Installation
Review this section and the Important Product Safety Instructions on page ii
before proceeding with the installation of your remote.
WARNING: Installations should be performed by qualified personnel, such as a licensed or certified electrician. The installer
determines which safety codes apply and ensures all applicable
installation requirements are followed. Applicable installation codes
vary depending on the specific location and application.
CAUTION: When connecting battery power to the inverter, all
battery negative connections must be connected prior to the battery positive connections. When removing battery power from the
inverter, the battery positive should be removed before any battery
negative connections are disconnected. This prevents any communication chips/lines from becoming the DC return path to the
battery—causing permanent damage to all connected accessories.
Summation: Ensure all battery negative circuits are always connected before connecting or disconnecting battery positive.
2.1
Pre-Installation
Before proceeding, read the entire Installation section to determine how best
to install your ME-RC remote. The more thorough you plan in the beginning,
the better your inverter needs will be met.
2.1.1
•
•
•
•
Installation Guidelines
Before connecting any wires, determine the remote’s cable route throughout the home or vehicle/boat, both to and from the inverter.
Always check for existing electrical, plumbing, or other areas of potential
damage BEFORE drilling or cutting into walls to mount the remote.
Make sure all wires have a smooth bend radius and do not become kinked.
If installing this remote in a boat, RV, or truck ensure the conductors
passing through walls, bulkheads, or other structural members are protected. This minimizes insulation damage (such as chafing) which can
be caused by vibration or constant rubbing.
2.1.2
Unpacking and Inspection
Carefully remove the ME-RC remote from its shipping container and inspect
all contents. Verify the following items are included:
•
The ME-RC remote
•
50’ remote cable
•
Four #8 x 3/4 Phillips screws
•
ME-RC Owner’s Manual
If items appear to be missing or damaged, contact your authorized Magnum
Energy dealer or Magnum Energy, Inc. Save your proof-of-purchase as a
record of your ownership; it is needed if the unit should require in-warranty
service.
2.1.3
Tools Required
Installing the remote control is simple and requires the following tools:
• Phillips screwdriver
• Level
• Drill
• Cut-out tool (knife/saw)
• Pencil
• Drill Bit (7/64”)

2.2
Connecting the Remote Cable
The ME-RC comes with a remote cable to enable communication between
the inverter and the remote. The remote cable is a 50-foot, 4-conductor,
round twisted-pair, telephony standard with 6P4C (6-position/4-conductor)
connectors on each end. When the 6P4C connectors are held side by side with
both of the connector tabs facing the same way, the color of the conductors
in each connector is the opposite from top to bottom (see Figure 2-1).
Info: Twisted-pair cabling is a common form of wiring in which two
conductors are wound around each other for the purpose of cancelling out electromagnetic interference (i.e., crosstalk).

Note: The remote cable can be extended up to a length of 200 feet without
data degradation.

The ME-RC can be flush mounted through an opening in the wall. Find a
location that is clean, dry and protected. Allow room to access the remote’s
SELECT knob and to view the LEDs/display.
CAUTION: Ensure that no AC power is connected to the inverter,
and then according your inverter owner’s manual correctly connect
the inverter to the batteries.
CAUTION: Always check for hidden electrical wires, pipes and
cables BEFORE drilling, cutting, or screwing into walls or cabinets.
Info: The ME-RC can be surface mounted on a wall using the optional ME-BZ (remote bezel).

2.4.1
Flush Mount Installation Procedure
To flush mount, the wall opening must have at least a 2” (5 cm) depth to
allow room for the remote and the cable.
1. Cut an opening in the wall (Figure 2-4). Ensure there are no openings
around the display and enough material for the screws to secure the unit.
2. Drill four pilot holes for the #8 x 3/4 screws that will attach the remote to
the wall (refer to Figure 2-3 for remote hole locations and dimensions).
3. Route one end of the cable through the wall opening to the inverter/
charger, and then plug it into the RJ11 REMOTE port (blue label) on the
inverter/charger—inverter has DC power, but is OFF. See Figure 2-2.
4. Take the other end of the remote cable and while plugging it into the
back of the ME-RC, view the remote’s display to ensure the Power-up
Self Test initiates (see Section 2.5).
5. If the self test is successful, secure the ME-RC to the wall using the
four supplied Phillips screws. If the self test is unsuccessful, refer to the
Troubleshooting section.

Remote Feature to Inverter Compatibility
The ME-RC has many settings and is designed to work with the standard
features in your Magnum inverter—and/or other Magnum devices (i.e., MEAGS-N or ME-BMK). The ME-RC communicates with your inverter to allow
the set up and enabling of these standard features. However, when the MERC is released with new software, some of the features and functionality in
the remote may not be available in an inverter or networked accessory that
has an earlier software level. In this case, the setting is not recognized and
will not function. Use the steps below to help you determine which ME-RC
(Revision 2.7) menus/features are compatible with your inverter.
1. Go to: http://www.magnumenergy.com/Service/Compatibility.htm to
determine your inverter’s compatibility level (L1, L2, L3, or L4).
2. Use Table 3-1 to determine which ME-RC features/settings you want to
use, and what inverter compatibility level is required (see the “Inverter
Model/Level Required” column in Table 3-1).
3. If your inverter compatibility level is the same or greater than the level
required, your inverter can support the setting/feature you want.
4. If your inverter does not have the required compatibility level for a feature/setting you want, contact Magnum Energy for a software upgrade.
Info: The ME-RC compatibility matrix below is also available online to
download/print as a single page document and to enter user settings.

Remote Buttons and Menu Items
The five menu pushbuttons (SHORE, AGS, METER, SETUP, or TECH) allow the
inverter/charger system to be configured to your specific preferences. These
menus also allow you to access menu items that can help with monitoring
and troubleshooting your system.
This section covers each menu button’s function and its various configurable
settings. This helps to optimize the operation of the inverter/charger.
3.3.1
SHORE Menu
This menu button enables you to quickly change your Shore Max setting to
coordinate with the circuit breaker rating from the incoming AC source.
•
SHORE: Shore Max – This ensures the inverter AC loads receive the
maximum current available from the utility/generator. Whenever the
utility/generator is connected to the inverter (via AC HOT 1), the current
used to power the AC loads and to charge the batteries is monitored.
When the total current used to power the AC loads and charge the
batteries begins to approach the Shore Max setting, the current that was
used for charging the batteries is automatically reduced. This ensures
the AC loads have the needed current. (Not available on MM/MM-E/
MM-AE/MMS/MMS-E models)
Default setting: Shore Max = 30A
Range: 5-60A

Where should I set: Set the Shore Max setting to match the current rating
of the utility power or the generator’s circuit breaker. This setting controls
the input current differently depending on the inverter/charger model and
the AC input wiring configuration. Set per your inverter model below.
CAUTION: The Shore Max setting does not limit the current to the
inverter loads. If the current from the loads on the output of the
inverter are greater than the circuit breaker rating on the incoming
AC source, you may experience nuisance tripping on this breaker.
ME, MS, and RD Series: These models have two inputs (HOT IN 1 and HOT
IN 2), but the current is only monitored on HOT IN 1. On these models, when
wired as a dual-in configuration or as a single-in configuration—with only
the HOT IN 1 connected—the Shore Max setting should be set to the size
of the AC circuit breaker that feeds the HOT IN 1 input. On these models,
when wired as a single-in configuration with HOT IN 1 and HOT IN 2 jumped
together, set the Shore Max setting to half (x½) the input breaker size—as
half the current will pass through HOT IN 1 and the other half through HOT
IN 2 simultaneously.
MS-AE and MS-PAE Series: These models have two inputs (HOT IN 1 and
HOT IN 2), with the current monitored on each input at the same time. On
these models, since the input is from a single AC source, both of the input
currents are added together and divided in half to determine the Shore Max
setting. Whether the input circuit breaker is a dual-pole (120/240 VAC input)
or a single-pole (120 VAC only), set the Shore Max setting to the value of
only one of the breaker poles (i.e., 30A dual-pole = 30A setting, 30A singlepole = 30A setting).
MS-E, MS-PE, MSH-RE and MSH-M Series: These models may have
one (AC1) or two (AC2) inputs, with the current monitored on each input
separately. On these models, set the Shore Max setting to match the input
AC circuit breaker size.
Note: If the ME-RC is connected to a MSH-RE inverter, the Shore Max setting
applies to both inputs (AC1 and AC2).
Note: The MS Hybrid (MSH) Series inverter/chargers have Load Support Mode,
which allows the inverter power to operate in parallel with the incoming AC
power (Grid or Gen). This feature uses additional power from the inverter’s
battery to run loads greater than what the incoming AC power can run alone,
and prioritizes the power of any external DC source (i.e., solar, wind, etc.,)
over the incoming AC power to run inverter loads.

MM, MM-AE and MMS Series (and any export version of these
models): These models do not monitor current on the input, therefore
cannot benefit from the Shore Max setting or feature. On these models, the
Shore Max setting may be displayed and allow selection/adjustment, but will
not do anything to reduce the battery charger current.

METER: 01 INV/CHG Meter – This menu item displays the DC voltage
and current while either inverting or charging.
DC: V (Volts) & A (Amps): First value displays the voltage from the
batteries connected to the inverter. This reading’s accuracy is ±1.5%
with a 0.1 VDC resolution. Second value displays (while inverting) a
negative number to show the battery current used by the inverter. If
charging, the DC: A (Amps) reading displays a positive number to show
the amount of current delivered to the batteries. The accuracy of this
display below 1 amp AC (~10 amps DC @ 12VDC) is not detected. When
the current into or out of the batteries is greater than 1 amp AC, the
display accuracy is ±20%.
VAC Out: Display provides the AC voltage measurement at the inverter’s
output terminals. If inverting, this measures the inverter’s output
voltage. When in Standby mode, this measures the AC voltage that is
passing through the inverter from the source (e.g., grid or generator).
Hz Out: Displays (while inverting) the output frequency of the inverter.
When in Standby mode, this meter displays the frequency of the
incoming AC source (i.e., grid or generator) that is passing through the
inverter to the inverter’s output terminals. Frequency in Hertz (Hz).
Load Amps: Displays the AC amps as measured on the inverter’s AC
output terminals. The reading is positive (+) if power is being pulled

from the inverter to run an AC load—either using the batteries in
Inverter mode, or from the AC input source in Standby mode. The
reading is negative (–) to indicate power is being returned to the inverter
through the AC output terminals—possible in an AC coupled installation.
(MS-PAE, MS-PE and MSH Series models only)
Input Amp: Displays the total AC amps being used by the inverter
for charging and for powering any connected load at the output of the
inverter. This reading is always displayed as a positive (+) number. (MSPAE, MS-PE and MSH Series models only)
Example: If the charger is using 20A from the AC source and the load
connected to the inverter output is using 10A, the combined load on
the incoming AC source is 30A. So, 30A is displayed as the input amps.
I/C Amps: Displays the inverter or charger amps. A negative (–) amps
reading indicates the inverter is powering the inverter loads and the
batteries are discharging (inverter amps). A positive (+) amps reading
indicates the inverter is using the AC input source to charge the batteries
(charger amps). (MS-PAE, MS-PE and MSH Series models only)
AC Input: Displays the RMS value of the AC voltage at the inverter’s
AC1/HOT IN 1 and NEUTRAL terminals. (MSH Models only)

Figure 3-6, SETUP: 01 Search Watts Selections
Info: When the Search Watts feature is active, “Searching” appears on
the top line of the LCD display and the green INV LED will slowly flash.
What is the Search Watts feature? This feature is used to help save
battery power by reducing the inverter’s output to search pulses when there
is no detectable load. If a load greater than the wattage level setting turns
on while the inverter is searching, the inverter will start inverting to provide
full voltage on its output.
Should I use the Search Watts feature? If the inverter can spend a great
deal of time searching (to reduce the power drain on your batteries) and you
can tolerate small loads (<5 watts) being off, then the Search mode feature
should be used. However, if some small loads (i.e., digital clocks, satellite
receivers, answering machines, etc.,) are required to be on, then this feature
should be turned off (Search = OFF).
Where should I set Search Watts? This setting should be adjusted to the
same power level (or the next lower setting) of the smallest load that you plan
to run. If you don’t know the wattage of the smallest load, turn the load on and
decrease the Search Watts setting until the load comes on and stays on.
Info: Even though the Search feature is on, some connected equipment—even if they are off—may draw enough current to keep the
inverter in the Inverting mode (i.e., not “Searching”).
•
SETUP: 02 LowBattCutOut – The LBCO setting is used to set the DC
voltage level that turns off the inverter to help protect the batteries from
over-discharge damage. If the battery voltage drops below the LBCO
selected set-point continuously for more than one minute, the FAULT
LED will come on, the inverter will turn off, and the display will show
a Low Battery status. If the battery voltage falls below 8.5 volts (12volt models), 17.0 (24-volt models) or 34.0 volts (48-volt models), the
FAULT LED and Low Battery status display will be immediate.
Default settings: LBCO = 10.0 VDC (12v models), 20.0 VDC (24v
models), or 40.0 VDC (48v models)
Range: 9.0-12.2 VDC (12v inverter), 18.0-24.4 VDC (24v inverter), or
36.0-48.8 VDC (48v inverter)
Info: The inverter automatically begins inverting when the DC voltage increases to ≥ 12.5 VDC (12-volt models), ≥ 25.0 VDC (24-volt
models), or ≥ 50.0 VDC (48-volt models). If AC power is available
and connected to the inverter’s input, the inverter automatically
clears the low battery fault, passes the input AC power to the output,
and begins charging the batteries.

Where do I set the LBCO setting? If you want to cycle the batteries
slightly—but don’t want to discharge them more than 20%*—then the LBCO
setting should be set from 11.5-12.2 VDC (12-volt models), 23.0-24.4 VDC
(24-volt models), or 46.0-48.8 (48-volt models). In some applications, such
as those installed in an off-grid home or when doing a lot of dry-camping
in your RV, you may want to cycle down to 50%* by setting the LBCO from
10.0-11.4 VDC (12-volt models), 20.0-22.8 VDC (24-volt models), or 40.045.6 VDC (48-volt models). In extreme circumstances, you have the ability
to discharge the batteries to 80%* by setting the LBCO to 9.0-9.5 VDC (12volt models), 18.0-19.0 VDC (24-volt models), or 36.0-38.0 VDC (48-volt
models) before recharging.
* These are rough estimates. For accurate battery monitoring, a battery
monitor such as Magnum’s ME-BMK/ME-BMK-NS is required.
Info: The higher the LBCO setting, the less the inverter discharges
the batteries; which allows the batteries to have a longer life. The
down side to a higher LBCO setting is the need to charge more often
to prevent the inverter from shutting off in Fault mode.
Info: If there is an AGS-N installed, it should be set to start ≥1.0
volts higher than the LBCO setting—this is to prevent the inverter
from shutting down before the generator comes on.
•
SETUP: 03 Absorb Time – Used to determine when the charger
completes the Absorption stage and transitions to the Float stage.
Absorption is the second stage of the battery charging process and the
batteries will be almost fully charged. Refer to Table 3-2 to correlate the
battery capacity to the absorption time.
Default setting: Absorb Hrs = 1.5
Range: 0.0-25.5 Hrs
Info: If the Absorption stage is short or terminated, the batteries
may not receive a full charge. In contrast, if the Absorption stage
is too long the batteries may be overcharged. Either scenario may
cause damage to the batteries. Contact the battery manufacturer
for the best charge settings for your type of batteries.
Info: The range of the Absorb Time setting is dependent on the
revision of your inverter. With inverters having a revision 5.0 or
greater, the available range to use is 0.5-25.5 hrs. However, if your
inverter revision is less than 5.0, the actual range is only from 1.0
to 6.5 hrs. Any setting less than 1.0 hr or greater than 6.5 hrs is
not recognized and will cause the charger to revert to the default
setting of 1.5 hrs.

How do I determine my Battery Amp-Hour capacity? The inverter
requires deep cycle batteries, which are specifically made for continuous
use. The batteries are rated either by AHrs or reserve capacity in minutes.
•
Amp-hour (AH) capacity is a measurement of how many amps a battery
can deliver for a specified length of time (usually 20 hours) until the
voltage achieves 1.75 VDC/cell at 80° F.
•
Reserve Capacity (RC) is a measure of how many minutes a battery can
deliver a certain amount of current (usually 25A) and maintain a voltage
above 1.75 VDC/cell at 80° F.
Info: If using the Reserve Capacity (25A), the 20-hour AH capacity
can be estimated by multiplying ‘minutes reserve capacity’ by 50%.
Table 3-3 provides an estimated 20-hour amp-hour capacity based on the
group/code size, physical size, and voltage of the battery. If you are not
sure of your battery’s 20-hour AH rating, consult your battery manufacturer/
dealer or use the table below to obtain an estimate.

Once you’ve determined the amp-hour capacity of each battery, review how
your batteries are connected (parallel or series) to determine the total amphour capacity of the battery bank:
Parallel connection – batteries connected in parallel (positive to positive,
negative to negative) increase the AHr capacity of the battery bank, but
the voltage remains the same.
Example: A 12-volt battery bank with three 12-volt batteries that are rated
at 125 AHrs each. Each of the positive terminals are connected together and
each of the negative terminals are connected together (i.e., connected in
parallel). The AHrs of each battery connected in parallel are added together
(125 AH + 125 AH + 125 AH = 375 AH), but the voltage of the battery bank
stays the same (12 VDC).
Series connection – batteries connected in series (pos. to neg.) increase
the voltage of the battery bank, but the AHr rate remains the same.
Example: A 12-volt battery bank with two 6-volt batteries that are rated
at 220 AHrs. The positive terminal of the first battery is connected to the
negative terminal of the second battery (i.e., connected in series). Since the
two 6-volt batteries are connected in series, the voltage of the batteries are
added together to produce 12-volts (6 VDC + 6 VDC = 12 VDC), but the
amp-hour capacity of the battery bank does not change (220 AH).
In battery banks where you have batteries connected in series and in parallel,
the rules are the same. The batteries connected in series are referred to as a
‘series string’ and the amp-hour capacity doesn’t change. Each series string
is connected together in parallel to increase the amp-hour capacity. Add the
amp-hour capacity of each series string connected in parallel to determine
the total amp-hour capacity of the battery bank.

SETUP: 04 Battery Type – Used to select the battery type, which
determines the battery charge profile and ensures the batteries are
receiving the proper charge voltage. The fixed voltage selections are:
GEL (for Gel batteries), Flooded (for liquid lead acid batteries), AGM 1
(for Lifeline AGM batteries), and AGM 2 (for East Penn/Deka/Discover/
Trojan AGM batteries). The Custom selection allows the Float, Absorb,
and EQ voltage settings to be individually adjusted. See Table 3-4 to
determine specific charge voltage based on the battery type selected.
Default setting: BatType = Flooded, (Custom – Absorb = 14.4V,
Float = 13.2V, Equalize = 15.6V)
Range: Gel, Flooded, AGM 1, AGM 2, Custom (12.0-16.0V for 12v)

Info: The voltage settings in Table 3-4 are based on the Battery
Temperature Sensor (BTS) at a temperature of 77° F (25° C), or
the BTS not connected. If the BTS is connected, the actual charge
voltage will increase if the temperature around the BTS is below
77° F (25° C), and decrease if higher than 77° F (25° C). This ensures the batteries receive the correct charge voltage regardless
of temperature.

SETUP: 05 Charge Rate – Sets the maximum charge rate allowed
to charge the batteries during Bulk, Absorption, Float, and Equalize
charging. The Max Charge = 0% setting helps minimize charging
while continuing to allow pass-thru power. The rest of the selections
are provided to limit the charge rate to the battery bank, which helps
prevent battery overheating caused by charging at too high a charge rate.
The Max Charge selections are provided as a percentage of the inverter/
charger’s maximum charging capability. Refer to the label on the side of
the inverter (or owner’s manual) to determine the inverter’s maximum
charge rate. Once you find this maximum charge rate, determine the
percentage needed to limit the charge rate to your battery bank.
Default setting: Max Charge = 80%
Range: 0-100%
Example: The maximum charge rate of your inverter/charger is 120
amps and you need to limit the charge rate to 72 amps. Choose the
Max Charge = 60% setting (72 amps = 60% of 120 amps).
Info: If Max Charge = 0%, the topology of the inverter—when
connected to an AC source—will override the 0% setting and start
charging if the battery voltage is <11 VDC (12v models), <22 VDC
(24v models), or <44 VDC (48v models).

Figure 3-10, SETUP: 05 Charge Rate Selections
Where should I set my Maximum Charge Rate? The maximum charge
rate is generally set to a C/5* rate (C = the total amp-hour capacity of the
battery bank—using the 20-hour AH rate). The C/5 rate is usually used when
the objective is to charge the batteries as quickly as possible (i.e., 400 AH ÷
5 = 80 amp maximum charge rate). A lower rate such as C/20* is used when
the batteries need to be charged as slow as possible.
CAUTION: The C/5 or C/20 charge rate settings are guidelines; they
are not requirements on how you should set your battery charge
rate. For specific charge rate requirements, refer to your battery’s
manufacturer.
Info: If multiple inverter/chargers are used on a single battery bank,
you must ensure that the total charge rate from all inverter/chargers is limited to the maximum charge rate needed for your battery
bank. The maximum Charge Rate setting only limits the charging
on each inverter/charger individually, not on all inverter/chargers.
* C/5 or C/20 rate – charge rates are commonly expressed as a ratio of the total
amp-hour (AH) capacity of the battery bank. For example, with a 400 AH battery
bank (C = 400), the C/5 charge rate is 80 A (400/5 = 80 A).

SETUP: 06 VAC Dropout – Used to select the minimum AC voltage that
must be present on the input before the inverter/charger switches from
Inverter to Standby mode. This setting also determines the minimum
AC voltage threshold where the charger disengages and the inverter
(when turned on) will provide AC power from the batteries. This protects
AC loads from utility outages.
Default setting: Dropout = 80 VAC (Export models = 150 VAC)
Range: US models: 60-100 VAC, UPS Mode; Export models: 110-190
VAC, UPS Mode
Example: If this setting is set to Dropout = 60 VAC, then the AC input
voltage must be above 60 volts before the inverter will switch from Inverter
mode to Standby mode.
Example: If this setting is set to Dropout = 60 VAC, when the AC input
voltage drops to 60 volts the inverter will switch from Standby mode to
Inverter mode.

Figure 3-11, SETUP: 06 VAC Dropout Selections
Where do I set my VAC Dropout? It depends on the application and what
you are using as the AC source. The settings not only look at the incoming
voltage level to determine when to transfer, but also determine how quickly
the charger disconnects and starts inverting based of the fluctuations of the
incoming AC voltage.
Note: If the ME-RC is connected to a MSH-RE inverter, the VAC Dropout
setting applies to both inputs (AC1 and AC2).
Dropout = 60 VAC to 100 VAC (export inverter models – Dropout
= 120 VAC to 200 VAC): Use a VAC dropout setting from 60 VAC to 100
VAC (export models—dropout from 110 VAC to 190 VAC) when the AC
source may have fluctuations in RMS voltage. These settings attempt to
prevent the charger from disengaging unnecessarily due to poor quality
voltage, and are highly recommended if using a generator for charging.
The transfer time from Standby mode to Inverter mode is >16 milliseconds when using these settings.
Dropout = UPSmode: Use the UPS Mode setting when the AC source
is well regulated above 105 VAC (200 VAC for export inverter models)
and the inverter loads are sensitive to voltage fluctuations. This setting
is intolerant of voltage fluctuations and will provide a quick transfer. The
transfer time from Charge mode to Inverter mode is ≤16 milliseconds
when using this setting. Do not use this setting if using a generator as
your AC source.
Info: If you get nuisance AC disconnects, either change the setting
to 100 VAC or less (export inverter models—190 VAC or less), or
obtain a better voltage-regulated AC source.

SETUP: 09 Final Charge – The Final Charge stage setting is the stage
to which the charger will transition after the absorption stage has
finished—as set in the 03 Absorb Time menu.
Default setting: Final = Multi
Range: Multi, Float, Silent (Rebulk)
Set Final Charge = Multi – The Multi setting (which is short for “MultiStage”), transitions from the Absorption stage to Float. Once in the
Float stage for four hours with no DC load on the batteries, the charger
will enter the Full Charge stage (i.e., Battery Saver mode). In Full
Charge mode, the charger automatically stops charging but is still on
and actively monitoring the battery voltage. The charger will remain in
the Full Charge stage until the battery voltage drops below 12.7 VDC
for 12-volt batteries, 25.4 VDC for 24-volt batteries, and 50.8 VDC for
48-volt batteries—at which time it will return to the Float stage. These
battery voltages are the fully charged voltages of a battery at rest. The
charger will continue to cycle between Float and Full Charge as long as
incoming AC is available.
Info: When Multi is selected and the charger goes to Full Charge
mode, if another charge source (such as PV or wind) is charging the
batteries above the fully charged voltage, the charger will remain
in the Full Charge stage.
Why should I use Multi-Stage? Multi is the most commonly used charge
mode. It is suitable for most applications and will assure a full charge to
the batteries, without overcharging. If there is another alternate charge
source charging the batteries, such as PV, wind or hydro, then Multi mode
will use the inverter/charger to complete a full charge. The inverter/charger
will transition to Full Charge mode and the alternate charge source will then
maintain the battery voltage. If the alternate source is unable to maintain the
voltage, the charger will enter Float mode for another four hour period. The
Full Charge feature in the Multi mode also helps reduce water consumption
in flooded batteries when they are left in the charge mode for extended
periods, such as in a backup power application.
Set Final Charge Stage = Float – The Float stage is a maintenance
charge mode that maintains a constant voltage—while delivering up
to the maximum rated current of the charger in order to power any
DC loads connected to the batteries. Most 3-stage chargers finish the
charge mode in Float and remain in Float as long as an AC source is
available on the input of the charger. The float voltage is determined
by the battery type selected in the 03 Battery Type menu. Unlike Multi
mode, in Float mode there is no Full Charge feature.
Why should I use the Float Charge Stage? Float mode is typically used
when the charger is the only charge source connected to the batteries.
This mode will maintain the batteries at the float voltage. If using flooded
batteries and the charger is in float for an extended period, the water level
should be checked every two to three weeks for proper levels.
Set Final Charge Stage = Silent – Silent mode stops charging once it
transitions from Absorb mode to ‘Silent’. Once the charger enters Silent
mode the battery voltage is continuously monitored. If the batteries
fall to the Rebulk value, the charger restarts the Bulk Charge mode
and then transitions to Absorb Charge mode. After the Absorb Charge
mode, the charger again transitions to Silent mode. This silent to rebulk
to absorb and back to silent cycle will continue as long as it is required.
©2013 Magnum Energy, Inc.
24
3.0 Setup
ReBulk – When Silent mode is selected, you must also set the DC
voltage set-point where the charger restarts the Bulk Charge mode.
This setting should be at the lowest DC volts you want the batteries to
fall before starting a new bulk charge. Typically, the lowest DC volts the
batteries are allowed to fall is 12.0 to 12.2 VDC (12-volt systems), 24.0
to 24.4 VDC (24-volt systems), and 48.0 to 48.8 VDC (48-volt systems)
respectively.
Default setting: Rebulk = 12.0V (for 12v inverter)
Ranges: 12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0 VDC (48v)
Why should I use the Silent Stage? Silent mode is typically used when
an alternate charge source is available and able to fully charge or finish the
charge cycle after the Absorb stage. A major difference between Multi mode
and Silent mode is that the Silent mode returns to Bulk mode instead of Float
mode. In Silent mode you can also adjust the Rebulk set-point in order to
allow the alternate charge source to provide more of the battery charging.
•
SETUP: 10 Pwr Up Always – Allows the inverter to power up and
provide AC power automatically once DC voltage is connected to the
inverter.
Default setting: Pwr Up = NO
Range: YES, NO
What is the Power Up Always feature? Normally, when DC power is
connected to the inverter, the user is required to press the power button—on
the inverter or remote—to turn the inverter on. When the Power Up Always
feature is activated by selecting YES, the inverter is automatically turned
on and starts searching or inverting—depending on the 01 Search Watts
setting. Once the inverter has connected to DC power and is automatically
turned on, the power button—on the inverter or remote—can be used to turn
the inverter on or off.
Why use the Power Up Always feature? Some customers are familiar
with Uninterruptible Power Supplies (UPS) that power-up automatically
when DC power is connected. The Power Up Always feature can be used by
customers that want to obtain the same automatic power-up feature with
which they are familiar.

Operating the Inverter/Charger
5.2.1
Inverter Mode
Turning the inverter on: Press the ON/OFF INVERTER button to activate
the inverter function. The inverter will either be actively “inverting” by
using power from the batteries to power the AC loads; or, the inverter will
be “searching” for a load by using very little power from the batteries, if
in Search mode. The green INV LED is on when the inverter is actively
inverting, and flashes while searching.
Turning the inverter off: While the inverter is actively inverting or
searching, press the ON/OFF INVERTER button to switch the inverter function
off. This will turn the green INV LED off.
Inverter Standby – The inverter is a slave unit in a parallel stacked system.
Inverter Standby occurs when the inverter is enabled (green INV LED is on),
but not actively providing power from the batteries to the inverter loads.
During Inverter Standby mode, the loads connected to the inverter are
powered by the other inverters in the parallel stacked system. The standby
inverter will come on automatically if the AC loads increase and require more
inverter power.
5.2.2
Charger Mode
Turning the charger on: The Charge mode is automatically activated
and begins when acceptable AC power (utility or generator) is connected
to the input of the inverter. When in Charge mode, the display may show:
Absorb Charging, AC Coupling, Bulk Charging, Charger Standby, Charging,
Equalizing, Float Charging, Full Charge, Load Support AAC, Load Support
VDC, and Silent.
Charger Standby – While the charger is actively charging, press the ON/
OFF CHARGER button to switch the charger to Charger Standby. While in
Charger Standby, the incoming AC is still available on the inverter’s output,
but the charger is not allowed to charge. The LCD displays “Charger Standby”
and the CHG LED flashes.
Info: To resume charging, press the ON/OFF CHARGER button or
disconnect/reconnect AC power to the inverter’s input.
Equalize charging: Equalizing is a “controlled overcharge” performed after
the batteries have been fully charged. It helps to mix the battery electrolyte
(to reverse the buildup of stratification) and to remove sulfates that may
have built up on the plates. These conditions if left unchecked, will reduce
the overall capacity of the battery. To enable the Equalization charge, see
Figure 5-11 and the information on pages 39-40.
WARNING: Do not perform an Equalization charge without reading and following all safety precautions pertaining to charging/
equalization as noted in this manual and provided by the battery
manufacturer, and any equalization information in the inverter
owner’s manual.

Figure 5-11, Equalizing Mode
•
Equalizing – The battery charger is delivering the equalize voltage
to the batteries; see Table 3-4 to determine the equalize voltage for your
battery type.
Equalize charging can be enabled by the ON/OFF CHARGER button—if the
SETUP menu’s 04 Battery Type selection allows. Equalization charging can
only be enabled while the charger is in Float Charge or in Battery Saver mode
(i.e., Full Charge). To turn on Equalize charging, ensure the LCD display reads
“Float Charging” or “Full Charge”, then press and hold the ON/OFF CHARGER
button down (about 5 seconds) until the LCD screen displays “Equalizing”.
The Equalize charge will continue for 4 hours and then automatically stop and
return to Float Charging. The Equalize charge can be manually stopped by
pressing and holding the ON/OFF CHARGER button down (about 5 seconds)
until the LCD screen displays “Float Charging”.
During the Equalize Charge stage the batteries will begin gassing and
bubbling vigorously, which consumes water. Ensure each cell has adequate
distilled water levels prior to equalizing, and add water as needed after
equalizing.
How often should I equalize? Some experts recommend that heavily
used batteries should be equalized periodically, ranging anywhere from once
a month to once or twice per year. Other experts only recommend equalizing
when the cells have a low specific gravity, or when the difference between
any individual cell has a specific gravity reading greater than .015 after
being fully charged.
How long should I equalize? While the batteries are gassing, monitor the
specific gravity readings every hour. When the specific gravity readings no
longer increase, the Equalization charge is complete and should be stopped.
WARNING: Equalizing produces hydrogen and oxygen gas. Ensure
the battery compartment has adequate ventilation to dissipate this
gas to avoid explosions.
CAUTION: Ensure your batteries can be equalized—only equalize
your batteries if permitted by your battery manufacturer or dealer.
Performing an Equalize Charge on batteries other than liquid lead
acid or certain AGM types could permanently damage them. Refer
to your battery manufacturer/dealer for instructions on how to
properly equalize your batteries.
CAUTION: Ensure the DC loads will not be damaged by the higher
voltage applied to the batteries during the Equalize Charge. If in
doubt, disconnect the DC loads to prevent damage.
Info: Equalization charging is not available if GEL or AGM 2 is selected under the SETUP menu’s 04 Battery Type menu.

preventing excessive loss of water in flooded batteries or drying out of GEL/
AGM batteries. After 4 hours Float Charging, the charger will turn off and “Full
Charge” is displayed (charger is now in Battery Saver™ mode). If the battery
voltage drops to ≤12.6 (12-volt models), ≤25.2 (24-volt models) or ≤50.4
(48-volt models), the charger will automatically initiate another 4 hours of

Figure 5-14, Load Support AAC Mode
•
Load Support AAC – The inverter is in the Load Support (Amps AC)
mode because the inverter load is requiring more power than the incoming
AC source can provide on its own. The inverter pulls the additional current—
needed for the loads—from the inverter batteries to keep the incoming AC
current from exceeding the SHORE: Shore Max setting.
Info: The Load Support AAC feature operates in parallel with the
AC input to support the inverter loads and is only available on MSH
Series inverter/chargers. It is only active when the AC input is qualified and connected, and the inverter is enabled (INV LED is on).

Info: When the inverter is in Inverter Standby mode (charging and
pass-thru), the current is normally a positive value. However, in Load
Support AAC mode, the inverter amps reading is a negative number
to indicate how much current is being provided/removed from the
inverter batteries. The inverter batteries will continue to provide
current to assist the AC input current until the battery reaches 0.5

•
Load Support VDC – The inverter/charger is in the Load Support (Volts
DC) mode because an external DC source (solar, wind, etc.,) is providing
more current than needed—which causes the battery voltage to rise. The
inverter/charger reduces the incoming AC current in an effort to keep the
battery voltage from rising above the temperature-compensated SETUP: 04
Battery Type setting.
Info: The Load Support VDC feature operates in parallel with the

The FAULT LED comes on and a fault status is displayed when an abnormal
condition is detected. View the LCD display and use the information in this
section to determine and correct the issue.
Info: Many of the faults will automatically restart when the fault
is cleared. Some faults will require a manual restart (ON/OFF INVERTER button on remote is pressed and released). Finally, if the
fault does not clear, an inverter reset (Section 6.2) may be required.

•
AC Backfeed – This fault message causes the inverter to shut down
because AC voltage from an external AC source has been detected on the
inverter’s AC output. An inverter reset or power reset will be required to
resume operation (see Sections 6.2 & 6.3).
Remedy: This fault usually occurs because the AC output wiring is
connected to (or able to be connected to) the incoming AC source.
When this fault happens, all system wiring should be re-checked
to ensure the incoming hot and/or neutral wires are not able to be
connected to the AC output.

•
AC Overload – This fault message displays when the AC load on the
inverter/charger’s output has exceeded the inverter’s AC current protection
limits. If the overload lasts for less than 10 seconds, the unit will automatically
restart and resume operation. However, if the overload occurs for more than
10 seconds, the unit will shut down and will require a manual restart.
Remedy: This fault usually occurs because the connected AC loads
are larger than inverter’s output capacity, there is a wiring short
on the output, or the output wires are incorrectly wired. Once the
AC loads are reduced or the output wiring is corrected, the inverter
can be restarted after a manual restart has been accomplished.

Dead Battery Charge – This fault has detected a very discharged
battery bank, or a battery bank not connected to the inverter. The unit is
attempting to enter the Charge mode, but has detected less than 9 volts
(12-volt models), 18 volts (for 24-volt models), or 36 volts (for 48-volt
models) on the battery bank.
Remedy: Check the DC voltage on the inverter’s DC terminals
and ensure it is the same as the battery bank—these two voltages
should be very close (<0.5 VDC difference). If not, check to ensure
all connections are tight and the fuse/circuit breaker between the
inverter and battery bank is good.
This fault automatically clears if the AC input power is removed or
when the voltage is greater than 12.6 volts (12-volt models), 25.2

•
FET Overload – This fault message indicates the inverter/charger has
shut down because the internal FETs (Field Effect Transistors) have quickly
exceeded a safe operating temperature. When the FETs have cooled, the unit
will require a manual restart to resume operation.
Remedy: If the fault continues to occur, disconnect all the inverter’s
AC output wires and reset the inverter (see Section 6.2). If this fault

High Battery – The inverter has turned off because the battery voltage
is at a very high level. The fault occurs when the battery voltage is above the
High Battery Cut-Out (HBCO) value. The inverter will automatically restart
and resume operation when the battery voltage drops 0.3 VDC (12-volt
models), 0.6 VDC (24-volt models), or 1.2 VDC (48-volt models) below the
HBCO value.
Info: The HBCO value is dependent on your inverter revision and
model. Normally, the HBCO value for ME/MM/RD Series inverters is
preset to 16 VDC (12-volt models) or 32 VDC (24-volt models). The
HBCO value for MS/MMS Series inverters is preset to 17 VDC (12volt models), 34 VDC (24-volt models), or 68 VDC (48-volt models).

•
High Battery Temperature – This fault message indicates the inverter/
charger has shut down because the Battery Temperature Sensor (BTS) has
reached a temperature greater than 54°C/129°F.
Remedy: Once the BTS cools down (≤49°C/120°F) it automatically
restarts and continues operation. As a precaution, check the BTS
location; if placed on a battery, ensure they are not overheated, or
that the BTS hasn’t been placed in a hot area or near a hot device.
If neither of these are the issue, then monitor the BTS display under
the TECH/01 Temperatures menu—this reading should be above
54°C/129°F. Now remove the BTS from the inverter BTS port. If
the BTS reading goes to 25°C/77°F, replace the BTS. If the reading
does not go to 25°C/77°F, then inspect the BTS port for cleanliness
and/or have the inverter/charger serviced.

condition lasts for less than 10 seconds, the unit will automatically restart
and resume operation. However, if the overcurrent condition occurs for more
than 10 seconds, the unit will shut down and will require a manual restart.
Remedy: This fault usually occurs because the connected AC loads
are larger than the inverter’s output capacity, there is a wiring short
on the AC output, or the wires are incorrectly installed. Once the
AC loads are reduced or the output wiring is corrected, manually
restart the inverter to resume operation. If this fault condition continues after all these recommendations, perform a inverter reset

©2013 Magnum Energy, Inc.
5.0 Operation
Remedy: The AC pass-thru relay is most likely stuck. A relay usually sticks because of damage to the contacts from trying to handle
currents greater than they are rated. This is usually caused by not
protecting the relay from handling high continuous currents, or by
switching high current inductive loads. The internal relay contacts are
rated to handle 30 amps AC continuously and should be protected
with a breaker sized no larger than 30 amps. If you are connected
to an AC source (grid or generator) and running large inductive
loads (i.e., pumps, motors, etc.,) on the inverter output, turn those
particular loads off prior to removing the AC input source. This fault
requires an inverter or power reset (Sections 6.2 & 6.3) to clear.

Inverter/Charger Troubleshooting Tips
6.1.1
Inverter Problems
•
Inverter turned on, green INV LED on inverter blinking, no
output: Inverter is in Search mode. Either turn off Search mode—if not
needed—or turn on loads greater than the Search Watts setting.
6.1.2
Charger Problems
•
Unit won’t transfer to Charge mode with AC applied: Is charge
(CHG) LED on remote blinking? If not, then the charger does not recognize
the incoming AC being within acceptable limits. Measure the input AC voltage
at the inverter input terminals—should be 120VAC +/ 20 VAC (230 VAC +/40 VAC for export models). Also, check that the VAC Dropout setting on the
remote is 80 VAC or less (160 VAC or less for export models). If the CHG LED
is blinking, the transfer relay should close within 20 seconds and the unit
should then begin charging. If the LED is on solid, the transfer relay should
be closed and the charger should be charging.
•
Transfer relay closes, then opens and continues to cycle: AC
voltage is too low, or has transients that drop the AC voltage momentarily.
Change the VAC Dropout setting to 60 VAC (110 VAC for export models) and
check for improvements. If the cycling continues, back off the Charge Rate
from 100% to 10% (or OFF, if available).
This cycling may also occur if the AC output of the inverter is connected to
the inverter’s AC input. Check for proper input and output AC wiring.
•
Charger not charging even though CHG LED is on steady and the
unit says “Charging”: Full charge rates are not obtained in Charging mode,
only obtained after this mode changes to Bulk Charging, Absorb Charging, or
Float Charging modes.
•
Charger not charging even though CHG LED is on steady and the
unit says “Bulk Charging” (or “Absorb Charging”): Check the DC Amps
and the DC Volts meters on the ME-RC display, it should be 80% or more of
rated charge current if the battery voltage is under 14.0 VDC (28.0 VDC on
24-volt models or 48.0 VDC for 48-volt models). If not, check the 05 Charge
Rate setting and verify the setting is 80% or greater. Still low charge rate?
Check the Shore Max setting to verify. If no AC loads are being ‘passed thru’
the inverter, the Shore Max setting must be 15 amps (25 amps for 3kW unit)
or greater, to receive full charge rate.
•
Charger says “Float Charging” not “Bulk Charging” when the AC
is first plugged in: Check the DC Volts meter on the ME-RC display. If
the battery is over 13.0 VDC (26.0 VDC for 24-volt models or 52.0 VDC
for 48-volt models) then the battery was already charged, and the charger
automatically goes to Float Charging to keep from overcharging the batteries.
•
Charge amps are lower than expected, or is 0 amps DC: Measure
input AC voltage and increase if the input voltage is under 90 VAC. The
charge rate is reduced to keep the input voltage above 90 VAC. Also, check
the Shore Max and 05 Charge Rate settings to determine if the current is
being limited.
•
Charger output voltage is higher than expected: Check the Battery
Temperature Sensor (BTS) temperature. If the BTS is installed, the charge
voltage settings will increase if the temperature around the BTS is below 77°
F (25° C), and will decrease if the temperature around the BTS is higher than
77° F (25° C).

6.2
Performing an Inverter Reset
To perform an inverter reset (i.e., “soft reset”):
1. Remove all AC power (utility or generator power) to the inverter.
2. Press and hold the inverter’s Power ON/OFF pushbutton (see Figure 6-1)
for approximately fifteen (15) seconds—until the inverter’s Charging/
Inverting Status LED comes on and flashes rapidly.
3. Once the rapid flashing has begun, release the Power ON/OFF
pushbutton. The Status LED will go off after the button is released.
4. After the inverter reset is completed, press the inverter’s Power ON/OFF
pushbutton to turn on the inverter.
Some older inverter models do not allow an inverter reset. If the inverter
reset fails, you will need to perform a power reset using the procedure below.
In either case, if an internal fault does not clear the inverter will require
repair at a Magnum Authorized Service Center (ASC).
Info: The Power ON/OFF pushbutton is a small momentary type
switch which operates by lightly pressing and releasing.
Info: All adjustable inverter/charger settings in the ME-RC (except
for the SHORE menu’s Shore Max and SETUP menu’s 08 Screen Setup settings (which revert back to default) are saved in non-volatile
memory and are preserved until changed—even if an inverter reset
is performed, or if all power to the remote or inverter is removed.
1. Ensure all AC power (i.e.,
shorepower or generator) is
removed from the inverter’s input.
2. Press and hold the Power ON/
OFF pushbutton for 15 seconds.
3. Watch the Charging/Inverting
Status LED, after approximately 15
seconds it should come on and flash
rapidly to indicate the inverter has
reset. The Status LED will go off
after the pushbutton is released.
Figure 6-1, Performing an Inverter Reset
6.3
Performing a Power Reset
To perform a power reset (i.e., “hard reset”):
1. Remove all AC power (utility or generator power) to the inverter.
2. Open all the inverter DC disconnects (or disconnect the positive battery
cable to the inverter).
3. Ensure the inverter and the remote are disconnected from all AC and DC
power (the remote display will be blank).
4. After the inverter has been disconnected from all power for 30 seconds,
reconnect the inverter DC disconnects (or reconnect the positive battery
cable) and resume operation.
Info: If DC disconnects are not used, there may be a momentary
spark when the positive battery cable is connected to the inverter’s
terminal. This is normal and indicates that the inverter’s internal
capacitors are being charged.

Press the AGS button on ME-RC remote (Figure 7-1), and then rotate
the SELECT knob to navigate to the AGS menus. These menus allow the
generator to be automatically started and stopped based on different
parameters. Using Table 7-1, determine the specific autostart and autostop
condition with which you want the generator to be automatically controlled,
and then use that specific menu setting to configure the AGS.
Note: For information on using the AGS: 01 AGS Control, AGS: 02 AGS

AGS: 03 Run Time Hour Menu
This menu provides the settings that determine the length of time the
generator will run once it has been autostarted by the AGS.
Default setting: Run Time = 2.0 Hrs
Range: 0.5 - 25.5 Hrs (0.5 hr increments)
How long should I set the generator run time? This depends on whether
you are using the high temperature or low battery voltage autostart feature.
•
Using high temperature to autostart: When using the high
temperature autostart feature, the generator autostarts and runs until
the AGS: 04 Start Temp F setting is reached. This means you could set
the time to the lowest time setting (0.5 Hrs), knowing the generator will
run until the temperature setting is satisfied.
•
Using low battery voltage to autostart: When using the low battery
voltage autostart feature, the generator run time is normally set to
help re-charge the batteries. Use Table 7-2 below to help determine the
generator run time setting based on the 20-hour AH capacity of your
inverter’s battery bank.

AGS: 04 Start Temp F Menu
This menu allows you to set and enable a temperature value that will cause
the generator to automatically start—to power an air conditioner (A/C)
unit for cooling—based on an increase in temperature, or by using an air
conditioning thermostat control.
Info: Optional ME-PT1 or ME-PT2 pigtail adapters can be used to
connect an AC control circuit or a relay control circuit. For more
info, refer to the instruction sheet for each pigtail adapter—part #
64-0025 (ME-PT1 instructions), or #64-0026 (ME-PT2 instructions).
This temperature autostart feature requires that the AGS’s remote
temperature sensor cable or an optional ME-PT1 or ME-PT2 pigtail adapter
be connected to the REMOTE port on the AGS. The location of the remote
temperature sensor determines the area being monitored for temperature.
When the temperature around the remote temperature sensor (based on
the AGS: 08 AGS TECH menu’s Temp display) increases to the AGS: 04
Start Temp F setting, the generator automatically starts and runs based on
the AGS: 03 Run Time Hour setting. When this run time period is finished,
the temperature sensor reading is checked. If the temperature sensor (or
thermostat control—if using the optional pigtail adapter) reading is below the
AGS: 04 Start Temp F setting, the generator will autostop. If the temperature
©2013 Magnum Energy, Inc.

7.0 Using an AGS Module
sensor (or thermostat control) reading is above the AGS: 04 Start Temp F
setting, the generator will continue to run for a second run time period. At
the end of this second run time period, the temperature sensor reading (or
thermostat control) is checked again. This cycle continues as long as the
AGS: 01 AGS Control menu is set to Enable (or Enable w/QT).
If the temperature autostart feature is not needed, set to the OFF position.
•
65F - 95F – This setting determines the rising temperature value that
will trigger a generator autostart.
•
Ext Input – This setting is used when an optional AGS adapter (PT1 or
PT2) is used. When an AGS adapter is connected to the AGS’s REMOTE
port, an external command from a thermostat connection on an A/C
control unit causes the generator to start. See the ME-PT1 or ME-PT2
instruction sheets for info on pigtail adapters. (See 08 AGS TECH: Temp)
Default setting: StartTemp = OFF
Range: OFF, Ext Input, 65F - 95F (5 deg. increments)
Why should I use Start Temp? Typically, in a mobile application (RV or
boat) where the A/C unit is too much power for the inverter to run from the
batteries, this feature is used to start the generator to run an A/C unit. Many
RV and marine customers travel with pets and do not want them to be at risk
from dangerous inside temperatures if they are away from the coach/boat.
With this feature, you can set the A/C to turn on and then leave. If the inside
temperature rises to the start setting, the generator automatically starts to
provide power to the A/C unit. This keeps the area cool and comfortable—
plus, while the generator is on, the inverter batteries are being charged.
Where should I set Start Temp? If you are using this feature to power
an air conditioning unit, the AGS: 04 Start Temp F setting should be slightly
above the A/C unit’s thermostat “cool” temperature (usually around 70-72F).
Once the temperature setting is reached, the generator will start providing
power to the A/C unit. The reason the temperature is set above the A/C
unit’s thermostat is to ensure the A/C unit will run when the generator starts.
If the AGS’s temperature setting is below that of the air conditioning unit’s
thermostat setting, the generator will run, but the A/C unit is not calling for
a run period or cooling; your generator is running, but the power is not being
used by the A/C unit—resulting in wasted fuel and run time.
Info: If using temperature autostart to start a generator that is
powering two A/C units, it is suggested that the second A/C unit’s
thermostat be set 2° to 5° higher than the first A/C unit. This staggered setting will allow the first A/C unit to start and run in an effort
to keep the coach cool. If the temperature continues to rise inside
the coach, the second A/C unit will turn on to further cool the coach.
AGS: 05 Start Volts Menu
This menu allows you to set and enable a battery voltage value that causes
the generator to automatically start. Starting the generator on voltage is the
most common method of autostarting the generator—it is considered the
simplest and easiest to understand. When the battery voltage (on Terminals
#3 & #4) decreases to or below this setting for two continuous minutes,
the generator will automatically start and run based on the AGS: 03 Run
Time Hour setting. If the DC voltage start feature is not needed, ensure this
setting is set to the OFF position.
Default setting: Start VDC = 11.0 VDC (12v), 22.0 VDC (24v), 44.0
VDC (48v)
Range: 10.0-12.2 VDC (12v), 20.0-24.4 VDC (24v), 40.0-48.8 VDC (48v)
57
©2013 Magnum Energy, Inc.
7.0 Using an AGS Module
Info: The default settings and range are automatically determined
based on the connected inverter and the measured VDC.
Where should I set Start Volts? When setting the VDC start voltage, it
must be high enough to not over-discharge the battery, but also low enough
to keep from nuisance starting the generator. Typically, start volts is set based
on what is determined to be approximately 50% of the battery capacity.
Since this is an inverter/battery system, and the battery is normally loaded,
the VDC used to determine 50% battery capacity should be set lower than
what is shown on typical battery voltage SOC charts (approximately 11-11.5
in a 12-volt system), which show the battery at rest (not loaded).
Info: The DC voltage the AGS uses to determine when to autostart is
displayed in the AGS: 08 AGS TECH menu under the AGS VDC meter.
AGS: 06 Set Time Menu
This menu is used to set the ME-RC remote’s internal clock. The ME-RC
contains a real time clock that must be set for proper operation of the AGS
button’s 07 Quiet Time feature. If the Quiet Time feature is not used, the
time does not need to be set.
Info: The clock obtains power from the inverter and resets if the MERC is disconnected from the inverter, or the inverter is powered down.
To set the current time:
(From the 06 Set Time menu)
•
Hour – Rotate the SELECT knob to the correct hour of day, and then
press SELECT.
•
Minute – Rotate the SELECT knob to the correct minute setting, and
then press SELECT.
•
AM-PM – Rotate the SELECT knob to the appropriate AM or PM setting,
and then press SELECT.
AGS: 07 Quiet Time Menu
This setting is used to prevent the generator from autostarting during a
specific designated time period each day.
Info: If the generator is running when the Quiet Time start time
setting is reached, it automatically stops and does not allow the
generator` to autostart until after the Quiet Time stop time setting
has passed.
To enable, access the Quiet Time menu and select a time period.
Default setting: Quiet = OFF
Range: OFF, 9PM-7AM, 9PM-8AM, 9PM-9AM, 10PM-8AM, 11PM-8AM
Why should I use Quiet Time? Quiet Time is used when there are park
rules or local noise regulations that prevent generators from running during
a certain time. It is usually set in consideration of when people may be
sleeping. If there are no local rules or regulations, you may not want to use
Quiet Time—which would allow the generator to run at any time in a 24-hour
period.
Where should I set Quiet Time? Select the time period that coincides with
any local noise requirements, or any time period that you do not want the
generator to automatically run.

7.2
AGS Functional Tests
Once you establish all the autostart/autostop settings you need, perform the
following tests to verify that the AGS system is functioning correctly and the
communication from the remote/inverter to the ME-AGS-N is correct.
7.2.1
Remote to Generator Communication Test
This section describes how to determine the current AGS status and how to
use the ME-RC remote to start the generator.
7.2.1.1 Determining AGS Status
Use your ME-RC to determine the AGS’s status by pressing the AGS button,
rotating the SELECT knob to the 02 AGS Status menu, and then pressing
the SELECT knob.
The AGS’s status should be Off or Ready. If it displays either status, then
the remote/inverter is correctly communicating with the AGS. If the AGS
status displayed is not Off or Ready, then refer to Section 7.8.2 “Resolving
Operational Statuses” or Section 7.8.3 “Resolving Fault Statuses” for
assistance before continuing.
7.2.1.2 Starting the Generator from the Remote
To confirm that the generator will turn on and run from the remote:
1. Press the AGS button, the bottom line of the remote should display the
01 AGS Control menu.
2. Press the SELECT knob and rotate it to AGS = Test.
3. Press the SELECT knob to activate the generator test.
Once the generator starts, it should run for approximately 30-60 seconds
before automatically turning off. View the AGS module’s STATUS LED and
ensure it turns solid green (solid green STATUS LED means the generator
has started successfully and is providing the gen run sense signal to the AGS
module).
Note: If the generator attempted to start but did not run, continue to wait,
the AGS will attempt to start the generator 3 more times.
If your AGS/generator system passes all three steps (may attempt an
autostart 4 times), then the wiring from the AGS to the generator is correct.
You are now ready to activate the AGS using your remote control panel.
Info: The AGS attempts to start the generator 4 times. If after 4
attempts the generator fails to start, the STATUS LED turns red—
indicating a fault.
If the remote control displays an AGS fault (under 02 AGS Status) or the
AGS module’s STATUS LED shows a fault condition (solid red LED indication),
refer to Section 7.8.3 for assistance.
7.3
AGS Operation/Monitoring
This section covers the AGS menus in the ME-RC remote that determine how
to control and operate the generator. The section also includes menus that
are used to monitor starting and running conditions for the AGS and the
generator.
7.3.1
Controlling the AGS using the ME-RC
Press the AGS button, and then rotate and press the SELECT knob to access
the following menus:
59

7.0 Using an AGS Module
AGS: 01 AGS Control Menu
This menu is used to enable the AGS (selecting Enable or Enable
w/QT). A “Test” setting is also available to ensure the start/stop wiring from
the generator to the ME-AGS-N is correct. The available settings are:
•
OFF – This option disables the AGS’s generator start/stop functions. It
also turns the generator off if it is running from an autostart command.
When OFF is selected, the generator will not start automatically. This is
the default setting. If you have an AGS fault, select OFF to clear it.
Info: If DC power is lost to the remote or to the system, this menu
resets to the default OFF position for safety.
•
•
•
Enable – Select this option to have the AGS monitor temperature (04
Start Temp F) and/or the inverter’s battery voltage (05 Start Volts) to
determine when to automatically start the generator.
Test – Select this option to test the generator. This option starts the
generator, runs it for approximately 30-60 seconds, and then stops the
generator. Use this setting for testing generator wiring and operation.
After a successful start/stop sequence test, this selection returns to OFF.
Enable w/QT – Select this option to have the AGS monitor temperature
(04 Start Temp F) and/or the inverter’s battery voltage (05 Start Volts)
to determine when to automatically start the generator—with the Quiet
Time parameters enabled.
WARNING: Never allow the generator to start/run in an enclosed
garage or any other type of enclosed structure without proper ventilation. Carbon monoxide, an odorless, colorless, deadly gas may
accumulate and cause serious injury or death.
7.3.2
Monitoring the AGS using the ME-RC
The following menus are helpful for the proper operation and monitoring
of your AGS/generator system. Press the AGS button, and then rotate and
press the SELECT knob to access the following menus:
AGS: 02 AGS Status Menu
This menu allows you to view the AGS’s current status. There are 14
different status messages to identify the AGS’s current state, but only one is
displayed at any one time (refer to Figure 7-2).

7.0 Using an AGS Module
AGS: 08 AGS TECH Menu
This menu displays meter data on the operating condition of the generator
and AGS, and has an AGS mode setting.
•
Gen Run – Displays the number of hours the generator has been
currently running from an autostart condition. This menu does not
determine run time when the generator has been manually started.
•
AGS VDC – Displays the battery voltage currently connected to the AGS
(on Terminals #3 and #4). This voltage is used to power the AGS and is
the voltage reading the 05 Start Volts setting is monitoring to determine
when to start.
•
Temp – Displays the current temperature reading (##C/##F) of the
AGS temp sensor, and is the temperature the 04 Start Temp F setting is
monitoring to determine when to start. The following may also display:
TS Open: indicates the temperature sensor is not connected.
40C/104F: indicating a very hot temperature, this display usually
appears because there is a short (i.e., wires crossed, touching) in the
temperature sensor wires.
1C/33F: indicating a very cold temperature, this display usually appears
because there is an open (i.e., not connected, cut) in the temperature
sensor wires.
No Comm: there is no AGS connected.
•
AGS Rev – Displays the software revision of the connected AGS.
Info: The AGS accessory may display a “0.0” revision for several
reasons. Either the AGS is not installed, there is no communication
because of a bad or miswired network cable, the AGS is not powered, or the AGS is bad.
•
AGS Mode – This setting allows you to configure the AGS to comply with
RVIA standards¹. When the AGS is set to “RV”, the AGS is automatically
disabled any time the generator is manually turned on or off. Select
Other if your system is not for a RV, or your requirements do not need
the AGS to be disabled should the generator be manually started/
stopped.
Default setting: AGS Mode = RV
Settings: RV, Other
Info: When the RV mode is used and the AGS system feature is
required, the user will need to re-enable the AGS system each time
the generator is manually turned on or off.
Info: If the AGS is automatically disabled when using RV mode, the
AGS status displays “Lockout”.
Note¹ - RV manufacturers use the NFPA 1192 Standard on Recreational
Vehicles for installing an AGS system. This standard has a requirement that
states when the generator is manually turned on or off, the AGS system
must also be turned off. Selecting the “RV” setting satisfies this requirement
by automatically disabling the AGS system when it senses that the generator
has been manually turned on or off. In installations where the requirement
to automatically disable the AGS system is not needed, the “Other” setting
can be chosen. When the AGS is in the “Other” mode, manually turning the
generator off or on will not automatically disable the AGS system.

ME-AGS-N Remote Status Messages
A status message may be an operational or a fault message. Access the AGS
status menu (AGS button’s 02 AGS Status menu) to view the AGS’s current
operating status. This menu is important when determining if the AGS is
working correctly, or for troubleshooting an AGS installation.
7.7.1
AGS Remote Operational Statuses
Refer to Table 7-3 for a brief description of the possible AGS operational
statuses that may display.
Table 7-3, AGS Remote Operational Statuses
STATUS
DESCRIPTION
Ready
The AGS: 01 AGS Control menu is set to Enable or to Enable
w/QT, and the AGS is ready to automatically start the generator based on the AGS button’s active autostart settings.
No Comm
The AGS is not communicating with the inverter/remote.
This is a normal status if there is no AGS (Network version)
connected in the system. If an AGS is installed, then refer to
Section 7.8.2 “Resolving Operational Statuses”.
AC In
The inverter/charger is connected to another source such as
a grid or an alternate generator, and is not controlled by the
AGS. When AC In displays, the AGS is prevented or locked
out from all autostarting conditions, except for when the
generator needs to exercise—if enabled.
Off
The AGS: 01 AGS Control menu is set to OFF. This setting
will not allow the AGS to autostart the generator.
Manual
Run
Generator was started manually from a start/stop switch directly connected to the generator, and the AGS Mode = Other (if the AGS Mode=RV, a Lockout fault displays instead).
Note: AGS determines the generator has been manually turned on by
sensing a gen run sense voltage to Terminal #2 on the AGS’s 8-port terminal block. However, if the Gen Type DIP switch is set to “2-Wire Standby”—which does not require a gen run sense voltage—manually turning
the generator on displays a status of AC In rather than Manual Run.
Quiet
Time
The ME-AGS-N has entered Quiet Time per the AGS: 07
Quiet Time setting.
Note: The generator will not autostart during Quiet Time.
Lockout
Lockout occurs when the AGS system is automatically disabled because the generator has been started or stopped for
any condition outside the control of the AGS. This an RVIA

General AGS Operational Notes
If a fault condition occurs, select the OFF setting from the 01 AGS
Control menu, and then select Enable or Test. If the problem persists,
refer to your AGS Owner’s Manual.
When the gen control setting in the remote is in the OFF position,
all generator autostart functions are disabled and the AGS module’s
STATUS indicator will also be off.
When AGS control is set to Enabled and an autostart condition occurs,
it attempts an automatic generator start. This is done by closing its
internal relays (based on the Gen Type selection) to control the starter—
much like a person does when manually starting the generator. The
starter is turned on for short periods of time and then turned off. If the
AGS determines that the engine has started while cranking (STATUS
indicator lights solid green), the starter is turned off after a short delay.
If the engine does not start, another attempt is made to turn on the
starter after a long delay period. This is repeated until the generator

7.0 Using an AGS Module
starts or until all its start attempts are reached, which causes the AGS to
go into a fault condition (indicated by a blinking FAULT indication on the
remote and a solid red STATUS indicator on the AGS Module).
If using the temperature autostart feature in an RV coach, set the air
conditioner thermostat slightly less than the setting (04 Start Temp
F menu). If using two air conditioners, set the second air conditioner
thermostat 2° to 5° higher than the first air conditioner. This staggered
setting will allow the first air conditioner to start and run in an effort
to keep the coach cool. If the temperature continues to rise inside the
coach, the second air conditioner will turn on to further cool the coach.
When the generator starts successfully, the STATUS indicator on the AGS
module will turn solid green. The generator will run until an autostop
condition is reached or until it is manually turned off; at which time a
stop signal will be sent to the generator.
If the generator is running when the AGS module’s TEST button is
pressed (or the Test setting is selected from the 01 AGS Control menu),
the generator will stop and then start again. The generator will then run
for approximately 30-60 seconds before shutting off.
When using a ME-RC remote, there is a two-minute delay before the
AGS attempts to start the generator if the voltage to the AGS module
falls to the 05 Start Volts setting. There is no delay if the AGS attempts
to start the generator when the temperature around the remote AGS
temp sensor rises to the 04 Start Temp F setting.
Several autostart/autostop settings can be active at once. However, once
an autostart condition becomes active, all other autostart conditions are
ignored until the specific condition that caused the generator to start is
satisfied by its autostop condition. Once the generator has completed
this autostart/autostop cycle, the AGS immediately begins to monitor
for any active autostart/autostop settings again.

Resolving Operational Statuses
The following operational statuses can display on your remote control, and
some may indicate an abnormal condition. Use the info below to resolve.
•
No Comm – This is a normal status if there is no AGS installed. If an
AGS is installed, use the information below to determine the remedy.
Remedy: If an AGS is installed, then follow these steps:
1. Ensure the green READY indicator on the AGS module is on (blinking or solid) to indicate the AGS is getting power.
2. Ensure the communications cable is connected from the inverter’s
Network port to the AGS’s NETWORK port.
3. Ensure you have the correct communications cable.
•
AC In – A normal status when the input to the inverter/charger is
connected to an AC source such as utility/grid power, or to an alternate
generator that may not be controlled by the AGS.
Remedy: The AC In status prevents the AGS from autostarting. To
enable the AGS to autostart the generator, remove any AC power
connected to the input of the inverter/charger.
•
Lockout – This status indicates the AGS has been configured to comply
with RVIA requirements (for use in an RV). Lockout displays whenever
the generator is started/stopped for any condition outside the control
of the AGS. To clear or disable this status, refer to the remedies below.
Remedy: To clear a Lockout status: Go to the AGS: 01 AGS Control
menu (the current setting should be AGS = OFF), then press the
SELECT knob to re-enter the “OFF” selection. Once you re-select
the OFF setting, the Lockout status clears (now should read “OFF”).
You must re-enable the AGS for autostart operation by changing the
AGS control from AGS = OFF to AGS = Enable, or AGS = Enable w/
QT (under the AGS: 01 AGS Control menu).
Remedy: To disable the Lockout feature: If the AGS is not used in
an RV installation (or you do not need to comply with RVIA requirements), you can disable the Lockout feature. Under the AGS: 08
AGS TECH menu, access the AGS Mode setting and change it from
RV to Other (AGS Mode = Other).
7.8.3
Resolving Fault Statuses
For these faults, refer to the remedy that follows.
•
Fault Temp – The generator failed to autostart and run per the 04 Start
Temp F menu’s start parameters.
•
Fault Test – The generator failed to start and run after pressing the red
TEST pushbutton on the AGS module.
•
Fault VDC – The generator failed to autostart and run per the 05 Start
Volts menu’s start parameters.
Remedy: Fault message may display on the remote control if:
A. The AGS attempts to start the generator four times, but the gen
failed to start and run per the specific autostart parameters; or,
B. The generator started, but did not provide the correct gen run
sense signal to the AGS module. For either scenario, refer to the
AGS Owner’s Manual to troubleshoot.
©2013 Magnum Energy, Inc.
68
7.0 Using an AGS Module
Fault Gen Run – The generator successfully started and ran for more than
two minutes, but the generator unexpectedly stopped by itself before the
active AGS autostop condition was finished.
Info: The AGS module determines the generator is running by
monitoring the gen run sense voltage/signal. When this gen run
sense voltage/signal is no longer available, the AGS thinks the gen
is off or has stopped.
Info: Gen run fault detection is not active if the generator is manually started.
Remedy:
A. If the generator is still running: Confirm you are getting the correct gen run sense signal to the AGS module. For further assistance,
refer to your AGS Owner’s Manual.
B. If the generator is not running: Check the generator for fault
codes and adequate fuel. If neither is an issue, check the generator’s owner’s manual for troubleshooting tips to determine why it
may have shut down on its own.
7.8.4
How to Clear AGS Faults
Go to the AGS: 01 AGS Control menu and select AGS= OFF.
Note: After the fault clears and the reason for the fault is determined, be
sure to re-enable the AGS to autostart. Go to the AGS: 01 AGS Control menu
and select AGS= Enable or AGS= Enable w/QT.
Once the fault is cleared and the reason for the fault is determined, you
should re-enable the AGS to see if the fault returns, or test the AGS/
generator system by performing the AGS Functional Test for your remote
(see your AGS Owner’s Manual).

8.0 Using a BMK
8.0
Using a ME-BMK
This section discusses how to set up and operate the BMK using the ME-RC50
remote. It also shows what BMK menu options are available using this remote.
8.1
Understanding Charge Efficiency
The first section provides information about charge efficiency and how to
manually access/adjust this setting. Normally, the ME-BMK battery monitor
automatically calculates the battery’s efficiency.
What is Charge Efficiency? When a certain amount of energy is removed
or discharged from the battery, this removed energy will need to be returned
to keep the batteries at a 100% state of charge. As batteries are being
charged, they lose energy; either in the form of heat, or while gassing. This
loss of energy while charging means the battery will not be fully charged
if you only return the current that was removed. To compensate for the
battery’s inefficiencies while charging, a charge efficiency setting is provided.
The charge efficiency setting compensates the AH I/O (Amp-Hrs In/Out)
reading by ensuring the AHrs returned to the battery are greater than the
AHrs removed.
For example, if your AH I/O display reads “000” and you begin powering a 25
amp load for two hours, the display will show -050. This indicates that you
have discharged 50 AHrs (2 x 25) from the battery. If the charge efficiency
setting is set to 95%, then as you begin charging and return 50 AHrs, the AH
I/O reading will be less than zero, indicating that the AHrs removed have not
been fully returned. The 95% charge efficiency setting requires 52.5 AHrs
(50/95) to be returned before the AH I/O returns to 0.
Info: The factory default charge efficiency setting is Auto. This setting allows the charging efficiency to be automatically calculated.
In most circumstances, the Auto setting will determine the best
charge efficiency.
CAUTION: If you do not know your battery’s charging efficiency,
leave it at the factory default setting. If the setting is manually set
but incorrect, the state-of-charge information will become more
inaccurate with every charge.
8.1.1

8.1.2
Adjusting the Charge Efficiency Setting
The Charge Efficiency setting determines how the battery monitor calculates
the battery’s charge efficiency. The charge efficiency can be calculated
automatically using the Auto setting, or can be manually programmed by
the user (see Figure 8-2).
The battery monitor is shipped with the charge efficiency set to Auto. This
allows the battery monitor to automatically calculate variables that affect the
charging efficiency—such as battery type, battery age, and how the batteries
are maintained—which is not always constant. With the Auto setting, the
efficiency is recalculated each time the batteries reach a 100% SOC.
This setting can also be manually adjusted from 50% to 97% to calculate the
AH I/O reading—if the battery’s charge efficiency is known. For example, if
you set the charge efficiency to 90%, and 100 AHrs are removed from the
battery, the AH I/O display would read 000 only after 111 AHrs have been
returned to the battery.

Figure 8-2, Adjusting the Charge Efficiency Setting
If the charge efficiency is manually set and inaccurate, the SOC information
will be more inaccurate with every charge. For this reason, continually
monitor the AH I/O display under the remote’s METER button.
To access the AH I/O display: press the METER button, turn the SELECT
knob until the 03 BM: Meters menu appears, press the SELECT knob again,
and then turn the SELECT knob to the AH I/O display.
After several charge/discharge cycles (below 80% SOC), the AH I/O reading
should be slightly positive when the 02 BM: SOC Batt SOC display reads 99%.
To view the Batt SOC display: press the METER button, turn the SELECT
knob until the 02 BM: SOC menu appears. If the AH I/O reading is below 000
(negative#) when the Batt SOC display reads 99%, then increase the charge
efficiency setting. If you find that the AH I/O reading is substantially above
zero when Batt SOC reads 99%, then decrease the charge efficiency setting.
8.2
Adjusting the Batt AmpHrs Setting
It is important that the METER button’s 05 BM: Setup menu’s Batt Amphrs
setting is correct or else the calculations used to determine the 02 BM: SOC
display will be inaccurate.
To access the Batt AmpHrs setting: Press the METER button on the MERC, and then rotate the SELECT knob until the display shows the 05 BM:
Setup menu. When the 05 BM: Setup menu appears, press the SELECT knob
to display the BM Charge Eff menu item. Turn the SELECT knob until the BM

8.4
Operating the BMK using the ME-RC
This section explains how the ME-BMK battery monitor works, and how to
use the ME-RC50 remote control to obtain battery bank information. It also
covers the various LCD displays that are related to the battery monitor and
the status of the Sense Module’s LED indicator.
8.4.1
How the Battery Monitor (ME-BMK) Operates
The ME-BMK battery monitor uses a precision resistor known as a shunt
to measure current flow into and out of the battery. The shunt provides a
small voltage to the Sense Module that is proportional to the current flow.
When current starts flowing into or out of the battery, the Sense Module
measures the current flow and determines the amount of current removed
from and returned to the battery. The amount of current (or AHrs) removed
or returned is displayed on the remote control as the AH I/O (AHrs In/
Out). The AH I/O number is compensated by a charging efficiency value that
accounts for energy loses while charging, and is one of the factors used to
determine the battery’s State Of Charge (SOC).
The battery’s state of charge—which is the best indicator of the condition of
the batteries—is indicated on the Batt SOC display. This display will show that
the batteries are fully charged (i.e., Batt SOC = 100%) once the following
three conditions have been met:
1. The charging voltage has stabilized over a period of time.
2. The charging current has decreased to a low percentage of the amphour capacity—normally less than 2%.
3. The AHrs that were removed from the battery are within 1% of fully
being returned.
After the batteries have reached 100% SOC and have discharged ≥ 0.5% of
the battery capacity setting, the charge efficiency value will be recalculated
and the AH I/O read-out will reset to the recalculated value.
Info: Charging from a generator (non-inverter topology) adds some
concern about the cost of fuel. A balance should be considered
between the use of fuel and the need to charge your batteries to
100% SOC—to maintain the full service life of a battery. Batteries
discharged to 50% SOC and then normally recharged to 85-90%
SOC would be an efficient compromise between fuel cost and battery life. Trying to restore the last 10-15% of a full battery charge
requires a long time—typically several hours.
8.5
ME-RC METER Menu Items and Settings for BMK
Press the METER button on the ME-RC to access the different meters that
determine the status of the inverter/charger and battery system.
01 INV/CHG Meter – This menu provides the DC voltage and current of the
inverter/charger when inverting or charging. These are not BMK readings.
02 BM: SOC – This display is the best way to monitor the actual state of
the battery. The read only display shows the State Of Charge (SOC) for the
connected battery bank. The SOC represents the condition of the battery as
a percentage of the available capacity left in the battery. The range is 0% to
100%, where 100% represents a fully charged battery and 0% means the
battery is completely discharged.
When the Sense Module is first connected, the batteries will need to be fully
charged (i.e., Batt SOC = 100%) at least once to establish a SOC reference
73
©2013 Magnum Energy, Inc.
8.0 Using a BMK
point. While this reference point is being calculated, the display will show
“Think’n”, to indicate that the SOC reference point is being calculated. After
the batteries are fully charged, the display will change from Think’n to 100%
and begin to provide accurate SOC percentage values.
Info: Think’n can take up to several days depending on the charge
source and its ability to completely recharge the batteries (e.g., a
small PV array may not be large enough to replace all the AHrs in
a reasonable amount of time).
If the Sense Module is disconnected from power, this display resets to Think’n
and the batteries will require another full charge before this display begins
providing SOC percentage information.
Info: Try to limit battery discharging to 50% of capacity (keep
battery above 50% SOC). If batteries are allowed to be continually
discharged below 50% SOC, their effective service life will be considerably shorter. This 50% rule has been determined to be the best
compromise between available energy and the maximum number
of discharge cycles a battery can provide.
03 BM: Meters – This menu shows the battery bank’s DC voltage, DC
current, and AH information that has been provided by the battery meter.
The values for these meter displays are updated each second.
•
DC Volts – Displays the real-time battery voltage from
07.00 to 70.00 volts (± 0.02 volts).
•
DC Amps – Displays the real-time charge current (amps into the
battery) or discharge current (amps out of the battery). Charging is
shown as a positive (+) number and discharging is shown as a negative
(-) number. The range is from ±0.1 to 999 amps, with a 1.0% accuracy.
•
AH I/O (Amp-Hours In/Out) – Displays the AHrs returned to/removed
from the battery. When the value is positive, it represents AHrs returned
to the battery during any subsequent charging. A negative value
represents AHrs removed from a full battery. The range is ±32,768 AH.
When using the charge efficiency’s Auto setting, the AH I/O value is
recalculated after the battery has been fully charged (i.e., 100% SOC)
and ≥0.5% of the battery capacity has been discharged. If the Sense
Module is disconnected from power, the AH I/O value resets to zero.
Info: The AH I/O display correlates with the battery’s Batt Amphr
setting to help determine the 02 BM: SOC display.
Info: AH I/O example: if you run a 10-amp load for three hours,
the display will show -30 AH. When you begin charging, the display
will count from -30 AH back toward 0 AH.
•
rAH Out (Resettable AHrs Removed) – This meter displays the
total AHrs removed from the battery since it was last reset. This
display can be used as a battery load indicator to help identify and
monitor the battery load consumption. The range is 0 to 65,535.0
AHrs (0.1 amp-hour resolution).
To reset the AHrs value to zero, press and hold the rotary SELECT knob
for >5 seconds when this display is shown. After this display has been
reset, it will begin calculating and displaying new rAH Out values. This
display automatically resets to zero if the Sense Module is disconnected
from power.

•
tAH Out (Total AHrs Removed) – This meter displays the total AHrs
removed from the battery since the Sense Module was first connected.
This display can be used as a battery service life indicator. The value
is displayed in 0.1k [or 100 AHrs (“k” equals 1000)] resolution up to a
maximum of 6,553.5k AHrs (6,553,500 AHrs). The displayed number
resets to 0.0k when the Sense Module is disconnected from power.
04 BM: Status – This menu selection offers read only displays that give the
current operating status of the battery monitor. This selection also provides
information to determine if there is a power-up fault condition.
•
BM: Factory Fault – The BMK has lost its calibration setpoints that
were established at the factory.
•
BM: No Comm – The battery monitor is not communicating with the
remote. This typically means a ME-BMK is not installed in the system.
If installed, view the Sense Module LED and refer to your BMK owner’s
manual to help determine the issue.
•
BM: Pwr-up Fault – The battery monitor faulted when it was poweredup. The fault occurred because the power-up self-test failed. Refer to
your BMK owner’s manual.
•
BM: Ready – The battery monitor is connected and actively monitoring
the battery system.
05 BM: Setup – This menu allows the battery’s charging efficiency to be
automatically calculated or manually selected, and the battery’s amp-hours
to be set. Refer to Section 8.1 for more information on the Charge Efficiency
setting, and to Section 8.2 for the Batt AmpHr setting.
06 BM: TECH – These menu selections allow you to access the system
information used to assist service technicians in troubleshooting the battery
monitor or the charging system.
•

last reset. The voltage shown on the display is averaged each second,
and is helpful when troubleshooting or detecting an over-discharge
condition.
To reset this display, press and hold the rotary SELECT knob for 5 seconds
while the Min DC display is shown. After this value has been reset, the
display will begin monitoring and showing new minimum DC input values.
If the battery monitor is not connected or not communicating, the display
will show “0.0”.
•
Max DC – This menu displays the highest battery voltage since the last
reset. The voltage shown on the display is averaged each second, and
this allows you to check your charging system (battery charger, charge
controller, etc.,) to ensure the charging voltage has been attained. This
display is also helpful when troubleshooting or detecting if an overcharge condition has occurred.
To reset this display, press and hold the rotary SELECT knob for 5 seconds
while the Max DC display is shown. After this value has been reset, the
