FOR FUTURE REFERENCE

.

This chapter contains important safety and installation instructions for the

Freedom SW Inverter/Charger (Freedom SW). Each time, before using the

Freedom SW, READ ALL instructions and cautionary markings on or provided with the inverter/charger, the batteries, and all appropriate sections of this guide.

NOTE: The Freedom SW contains no user-serviceable parts.

ELECTRICAL SHOCK HAZARD

• Do not expose the Freedom SW to rain, snow, spray, or bilge water.

This inverter/charger is designed for marine applications only when additional drip protection is installed in certain orientations. See the installation guide for information.

• Do not operate the inverter/charger if it has received a sharp blow, been dropped, has cracks or openings in the enclosure including if the

AC terminal cover has been lost, damaged, or will not close, or otherwise damaged in any other way.

• Do not disassemble the inverter/charger. Internal capacitors remain charged after all power is disconnected.

• Disconnect both AC and DC power from the inverter/charger before attempting any maintenance or cleaning or working on any circuits connected to the inverter/charger. The INVERTER ENABLE button on the front panel does not function like a power switch that energizes or de-energizes the unit arbitrarily. When AC and DC power sources are connected and present, the unit is always energized.

• Do not operate the inverter/charger with damaged or substandard wiring. Make sure that all wiring is in good condition and is not undersized.

Failure to follow these instructions will result in death or serious injury.

iv Freedom SW Owner’s Guide

Freedom SW 3K2K InvChg Owners Guide.book Page v Thursday, July 31, 2014 1:42 PM

FIRE AND BURN HAZARD

• Do not cover or obstruct the air intake vent openings and/or install in a zero-clearance compartment.

• Do not use transformerless battery chargers in conjunction with the inverter/charger due to overheating.


EXPLOSION HAZARD

• Charge only properly rated (such as 12 V) lead-acid (GEL, AGM,

Flooded, or lead-calcium) rechargeable batteries because other battery types may explode.

• Do not work in the vicinity of lead-acid batteries. Batteries generate explosive gases during normal operation. See note #1.

• Do not install and/or operate in compartments containing flammable materials or in locations that require ignition-protected equipment.

See notes #2 and #3.


NOTES:

1.

Follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery. Review cautionary markings on these products and on the engine.

2.

This inverter/charger contains components which tend to produce arcs or sparks.

3.

Locations include any space containing gasoline-powered machinery, fuel tanks, as well as joints, fittings, or other connections between components of the fuel system.

4.

Freedom SW inverter/charger products are designed for deep cycle lead-acid batteries only. Charging lithium-ion batteries are currently not supported and doing so is an explosion hazard.

Lithium-ion battery cells are individually monitored for voltage and temperature. The Freedom SW does not support this individual cell monitoring on lithium-ion batteries.

Precautions When Working With Batteries

BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE

AND EXPLOSION FROM VENTED GASES HAZARDS

• Always wear proper, non-absorbent gloves, complete eye protection, and clothing protection. Avoid touching your eyes and wiping your forehead while working near batteries. See note #4.

• Remove all personal metal items, like rings, bracelets, and watches when working with batteries. See notes #5 and #6 below.

• Never smoke or allow a spark or flame near the engine or batteries.

• Never charge a frozen battery.

Failure to follow these instructions can result in death or serious injury.

5.

Use extra caution to reduce the risk or dropping a metal tool on the battery. It could spark or short circuit the battery or other electrical parts and could cause an explosion.

6.

Batteries can produce a short circuit current high enough to weld a ring or metal bracelet or the like to the battery terminal, causing a severe burn.

7.

When removing a battery, always remove the negative terminal from the battery first for systems with grounded negative. If it is grounded positive, remove the positive terminal first. Make sure all loads connected to the battery and all accessories are off so you don’t cause an arc.

NOTES:

1.

Mount and place the Freedom SW Inverter/Charger unit away from batteries in a well ventilated compartment.

2.

Always have someone within range of your voice or close enough to come to your aid when you work near a lead-acid battery.

3.

Always have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

4.

If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.

Precautions When Preparing to Charge Precautions When Placing the Inverter/Charger

EXPOSURE TO CHEMICALS AND GASES HAZARD

• Make sure the area around the battery is well ventilated.

• Make sure the voltage of the batteries matches the output voltage of the inverter/charger.

• Be careful to keep corrosion from coming into contact with your eyes and skin when cleaning battery terminals.


NOTES:

• Study and follow all of the battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, whether equalization is acceptable for your battery, and recommended rates of charge.

• For flooded non-sealed batteries, add distilled water in each cell until battery acid reaches the level specified by the battery manufacturer.

This helps to purge excessive gas from cells. Do not overfill. For a battery without removable cell caps, carefully follow manufacturer's instructions.

RISK OF DAMAGE TO THE INVERTER/CHARGER

• Never allow battery acid to drip on the inverter/charger when reading gravity, or filling battery.

• Never place the Freedom SW Inverter/Charger unit directly above batteries; gases from a battery will corrode and damage the inverter/ charger.

• Do not place a battery on top of the inverter/charger.

Failure to follow these instructions can damage the unit and/or damage other equipment.

Introduction

Key Features

The Freedom SW Inverter/Charger is a true sine wave inverter/ charger that can be used for mobile, marine and commercial applications. The Freedom SW Inverter/Chargers are designed to operate with a wide variety of generators and are capable of operating in parallel with a generator for short durations to assist with starting large loads. The Freedom SW is a convenient combination of an inverter, multistage battery charger, and transfer switch in one electronic device.

• As an inverter, the Freedom SW provides true sine wave power for your microwave, entertainment system, computer, and other loads. This power is identical to the AC source provided from the utility grid (power company).

• Some of the benefits of true sine wave power include consistent cooking in your microwave, handling of sensitive loads such as your TV set, dimmer switches, and appliances with speed controls.

• Highly versatile platform capable of series stacking for 120/

240V line configurations and parallel stacking to increase power levels.

• High efficiency true sine wave output to power sensitive electrical and electronic equipment.

• Surge capacity to start difficult loads like refrigerators or A/C compressors.

• Power factor-corrected (PFC) input minimizes AC input current required for charging, increasing AC pass-through capacity.

• As a charger, it has high output, multistage charging capability minimizing charging time.

• Capable of operating from 50 Hz and 60 Hz power source by

extending AC qualification frequency range. See “ACIn

Settings” on page 55.

IMPORTANT: Dual Line models require only the Line 1 Input to be energized in order to qualify AC. Line 2 Input does not have to be powered in a single phase system.

• Temperature-controlled, variable-speed internal cooling fans.

The fans turn on when the internal temperature reaches 45 °C

(113 °F) and reaches maximum speed at 70 °C (158 °F). The fan turns off when the internal temperature falls to 40 °C

(104 °F).

• Designed with serviceability in mind via Authorized Service

Centers (ASC).

• The Freedom SW Inverter/Charger is also Xanbus-enabled which allows network compatibility and communication with other Xanbus-enabled devices. See more information under

“System Components” on page 6.

Introduction

Key Features Explained

Built-in Charge Formulas

For the unit to perform at the highest level, the batteries must be charged correctly. The Freedom SW has optimized algorithms for flooded, gel, and AGM batteries.

Battery Temperature Sensor

Since battery temperature is a key factor in correct charging, the charging formula must be adjusted

(automatically and in real time) according to the actual battery temperature to ensure that batteries are fully charged, but not overcharged. For this reason, a battery temperature sensor is included with your Freedom SW and has temperature compensated the charge formula.

Manual Equalization

Over a period of time, the cells in a flooded battery can develop uneven chemical states. This can result in a weak (undercharged) cell which, in turn, can reduce the overall capacity of the battery. To improve the life and performance of a non-sealed, flooded battery, the Freedom SW’s multistage charging cycle includes a manual equalize mode that can be used, if recommended by the battery manufacturer.

Dead Battery Charging

Another feature that the Freedom SW includes is dead battery charging. The Freedom SW—unlike many chargers—has the ability to recharge batteries even if the battery voltage is very low (5 volts for Freedom SW 2012 / 3012 units and

12 volts for Freedom SW 2024 / 3024 units).

Load Management

The Freedom SW has a built-in transfer relay that connects your inverter output or AC input from the utility grid or generator to your loads. Because the usual AC power sources such as campground outlets or small generators often have limited current availability, having the capability to manage your AC loads is extremely valuable. The Freedom SW provides a number of features to facilitate this:

• The charger is power factor corrected to use AC current as efficiently as possible. Minimizing the AC current used by the charger means more current is available for your AC loads.

• Freedom SW has a power share feature which prioritizes your

AC loads by reducing the charge current in an attempt to limit the total input current to less than the breaker setting.

Occasionally, AC input sources have low voltage. To avoid loading these weak sources any further, the charger automatically reduces its AC current draw as the AC voltage approaches the minimum acceptable level.

Introduction

Stacking

Supports stacking of two inverter/chargers to increase capacity. This also requires the installer to select a Master and Slave in order for the inverters to stack. Two configurations of stacking are supported:

Parallel stacking and Series stacking.

Parallel Stacking

Parallel stacking allows two inverter/chargers to operate in parallel thereby doubling the capacity in inverter mode. The two inverters communicate over the network and intelligently share the load and to balance the load between the two units. The Master Freedom SW broadcasts pulses on the Xanbus network to synchronize operation between the other paralleled unit.

When AC loads are present, both units produce power, effectively sharing the load. When Search mode is enabled, only the Master unit produces the AC output.

Series Stacking

Two units can be configured to generate 120/240

Split-phase power for load configurations that require both 120 and

240 volts. In this configuration, the AC source must be split-phase as well.

Stack Charging

Two Freedom SWs synchronize charging stages to ensure efficient charging of the battery bank. When a single unit transitions from bulk to absorption so do all other units. In absorption, all units must complete the absorption stage before transitioning to the next stage.

Note that units do not load share when charging except during the bulk stage. The Freedom SWs stop sharing charge current just before completing the bulk stage. The units do not share charge current during the absorption and float stages.

Each unit charges batteries based on the Max Charge Rate setting and active internal (temperature-based) deratings.

If equalization is enabled on one or more devices capable of equalization charging, only those devices perform an equalize cycle after absorption. Other devices transition to float (if three-stage charging is selected) or transition to AC pass-through (if two-stage charging is selected).

Generator Assist

The Freedom SW Series of inverter/chargers can operate in tandem with a generator to temporarily assist power loads with large startup demands such as air conditioners, water pumps etc. A Xanbus

AGS must be installed in the system in order for this feature work.

When this mode is enabled and generator capacity defined, the inverter will come on-line and assist the generator when the generator reaches its capacity. The battery bank must be well charged in order for the inverter to engage this mode. For more

details, see “Gen Support” on page 56.



Introduction

Basic Protection Features

The Freedom SW has the following protection features:

• Over temperature shutdown for critical components such as the transformer and the power board

• Battery temperature sensor (BTS) failure/battery temperature out-of-range fault protection

• DC output over voltage protection during charge mode

• AC transfer relay failure detection

• AC output overload and short circuit protection during invert mode

• AC backfeed

1

protection

• Short circuit protection for the BTS and communication connector ports including protection from incorrectly inserting the remote panel communication cable plug into the BTS port and vice versa

The Battery Temperature Sensor (BTS) provides these protection features:

• Battery over temperature charging protection preventing battery charging at 60 °C (140 °F) or higher

• Charging voltage compensation based on the temperature of the battery where the BTS is connected

1.An AC backfeed error occurs when the AC output of the inverter/charger is connected or routed back to the inverter/charger’s AC input terminal or if the internal transfer relay fails.

System Components

The Freedom SW uses Xanbus, a network communications protocol developed to communicate the Freedom SW’s settings and activity to other Xanbus-enabled devices.

You can configure and monitor the Freedom SW and every Xanbusenabled device in the system using an optional Xanbus System

Control Panel (SCP).

Another component is the optional Xanbus Automatic Generator

Start (AGS) which allows operation with a wide range of generators, supported through a dedicated generator input. Simply, the AGS automatically starts and stops your generator.

The Freedom Sequence Intelligent Power Manager is a fully integrated power management system that provides automatic power and load management for use in recreational vehicles (RV) while receiving power from a generator or shore power. This device works in the background to prevent monitored AC loads from exceeding shore and generator breaker capacity.

See “Xanbus-enabled Products and Accessories” on page 8 for part

numbers.

Xanbus System

The Xanbus system includes the Freedom SW and other Xanbusenabled devices. The Freedom SW is the device in a Xanbus system that typically provides network power—500 mA at 12 volts DC. All of the Xanbus-enabled devices, such as the Freedom SW, the SCP, and the AGS are able to communicate their settings and activity to

each other. See Figure 2.

Freedom Inverter/Charger Operation

Start Up Behavior

When the Freedom SW is powered up or has been reset, all of the front panel LEDs turn on and remain on for a minimum of five seconds. During this interval, the fans are also turned on as the unit executes internal diagnostics.

Out of the box from the factory, when the Freedom SW is powered up (that is, when AC and DC power sources are connected) for the first time, the inverter function is disabled by default. After powering up, the INVERTER ENABLE button (or the “Up” button on the SCP) can be used to enable or disable inverter function. See

“Inverter Operation Using the Front Panel” on page 16 and “Enable/ disable inverter function (EnInv/DsInv)” on page 25.

Enable versus Disable

When a function is enabled, it is allowed to occur but other conditions may have to be met before the function actually works. For example, the charger function on the Freedom

SW may be enabled, but will not charge the battery unless qualified

AC power is present. For more information, see “Enabling a function” and “Disabling a function” on page 20.

IMPORTANT:

Review the “Important Safety Instructions” on page iv before operating the inverter/charger.

Storing Inverter State Feature

You can enable or disable a feature called StoreInvState which, when enabled remembers the state of the inverter function prior to a power down (that is, when

AC and DC power sources are disconnected) or prior to a Standby

(Power Save) mode. When the Freedom SW is powered up again or put back on Operating mode, the inverter function reverts back to its

prior state. See “To store the state of the inverter to memory:” on page 62. This feature is disabled by default.

This feature is available only to Freedom SW 2024 (PN: 815-2024).

Freedom Inverter/Charger Operation

Inverter Operation Using the Front Panel

IMPORTANT:

Review the “Important Safety Instructions” on page iv before operating the inverter/charger.

Once the inverter/charger is installed, you can operate it in invert mode.

To operate in invert mode from the front panel:

1.

Press the INVERTER ENABLE button on the Freedom SW on the front panel. The INVERTER ENABLED LED turns on and connected loads will be energized.

2.

Note that if AC is present and being passed through, the

INVERTER ENABLED LED will still turn on to indicate

inverter mode has been enabled. However, AC will continue to be passed through to the loads until conditions exist that cause

AC to be disqualified, in which case the unit will transition to invert mode and power up critical loads.

3.

Connect AC input power.

The charger automatically starts up when qualified AC power is connected.

To operate the inverter with the System Control Panel, refer to

“Operating the Freedom SW with the SCP” on page 19.

4.

Disconnect AC power from inverter input by opening the breaker or disconnect.

5.

Place a load on the inverter. For example, plug a 100-watt light bulb into an outlet that the inverter is powering. Press the

INVERTER ENABLE button on the Freedom SW. The

INVERTER ENABLED LED turns on. The inverter should

run the load using battery power.

6.

To test the charger, reconnect the AC input power to allow AC to the AC input. The AC In/Charging LED should start flashing after a brief delay. Any AC loads previously powered by the inverter will also work at this time.

NOTE: On dual input models, only AC Input L1 needs to be

powered for the unit to operate.

7.

Remove the AC input power. The inverter/charger should transfer to invert mode immediately. (The transfer relay will make a clicking sound and the INVERTER ENABLED LED will turn on.) Loads should continue to operate uninterrupted.

If any part of this test fails, determine the cause before using the unit.

8.

Monitor the Freedom SW Front Panel.

The indicator LEDs on the front panel show you the operating status of the Freedom SW. A description of the LEDs is provided in Table 1.

If none of the front panel LEDs are on, see “Troubleshooting” on page 69.

A warning is detected.

Your battery bank is being replenished and AC loads are receiving power.

Investigate and clear the fault condition.

Investigate by examining warning logs on SCP.

Faults and Warnings

A fault affects the operation of the unit. A manual fault requires user intervention by clearing the condition and then pressing the CLEAR FAULT RESET button on the inverter/ charger’s front panel. See the Xanbus System Control Panel

Owner’s Guide for information on clearing faults from the SCP.

A warning alerts you to a condition that could possibly affect operation of the unit.

IMPORTANT:

If you are having problems with any of your loads,

refer to “Inverter Applications” on page 70.

Temperature

The Freedom SW series of inverter/chargers will operate at rated power continuously at 30 °C with some models capable of continuous operation at much higher ambient temperature. However, the continuous power rating at elevated ambient temperature may differ between models. See

“Specifications” on page 81 for full details. In higher ambient

temperatures, if the loads draw full power for an extended period of time, the unit may shut down to protect itself against overheating.

The Freedom SW series of inverter chargers feature a surge rating of 200% of rated power for five seconds at 25 °C. Operating the inverter/charger in conditions outside of power and temperature limits, however, will result in thermal shutdown and/or significantly decreased performance. In addition, operation in this range is outside the ratings covered by the regulatory approvals of the product.

Difficulty on starting loads

The inverter/charger should be able to operate all AC loads rated at or below its power rating. Some high horsepower induction motors used in pumps and other motoroperated equipment require very high surge currents to start, and the inverter/charger may have difficulty starting these loads.

If you have problems starting certain loads, ensure that:

• Battery connections are tight and clean.

• DC cabling is no longer than the recommended length. Refer to the Freedom SW Sine Wave Inverter/Chargers Installation

Guide for this information.

97-0019-01-01 17



•

•

AC wiring is of recommended size. Refer to the Freedom SW

Sine Wave Inverter/Chargers Installation Guide for this information.

Battery is of sufficient capacity and is fully charged.

NOTE: Many 24 V inverter battery banks have a capacity between

200–400 Ah and 12 V inverter battery banks have a capacity between 400–800 Ah. Refer to the Freedom SW Sine Wave Inverter/

Chargers Installation Guide for sizing requirements.

Operating Limits for Charger Operation

By default, the maximum charger output current is the rated charger output current for the particular model. Using the SCP, you can reduce the total output if you change the maximum charge rate (Max

Chg Rate

) on the Freedom SW Basic Settings menu or Inverter

Settings menu under Advanced Settings.

The charger can operate within an AC input range of 95–135 volts.

The default settings are 95 and 135, which are the ACIn Lo Volt and ACIn Hi Volt respectively. The ACIn Lo Volt setting has a range of 78–115 volts and the ACIn Hi Volt setting has between

125 –140 volts.

AC Frequency

The charger can also be configured to accept and operate from a wide AC source frequency of 40–68 Hz. Therefore, the Freedom SW can charge your batteries even when incoming AC voltage is less than ideal. The default settings are 45 and 55 Hz, which are the ACIn Lo Freq and ACIn Hi Freq settings respectively.

18

Power sharing

The Freedom SW charger uses incoming AC or shore power (see following note) to charge the batteries. The charger shares incoming AC power with AC loads on Line 1 only.

The AC loads have priority, which means that the charger will reduce its output with large AC loads and increase the output again when the AC load decreases. The regulatory maximum for

continuous AC loads is 80% of the breaker rating (see “AC1

Breaker

” on page 44) that the loads are connected to. The Freedom

SW senses pass-through current going to the AC load. The difference between the pass-through (load) and 80% of the AC1

Breaker

setting is the current that is available for charging the batteries.

For example, if the AC input of the Freedom SW is from an AC panel with a 30-amp breaker, the AC1 Breaker setting on the SCP should be selected as 30 amps. Based on this, the charger will control the charge current so that the total current draw is equal to or less than 24 amps in this case. Should the load current be more than

24 amps, the charger output will reduce to 0 amp, but the Freedom

SW will continue to supply the loads. The Freedom SW will continue to pass-through power to the loads, even if the load current exceeds the AC1 Breaker setting. In this case, it will be up to the user to remove/disconnect loads if tripping the AC input breaker supplying the Freedom SW is to be avoided.

NOTE: The AC1 Breaker setting can also be changed using the

Shr

soft key in the SCP (see “Soft Key Navigation” on page 25).

Shr

stands for shore power which refers to incoming AC power in the mobile industry.



Operating the Freedom SW with the SCP

This section contains detailed information and procedures for using your Freedom SW in conjunction with the System Control Panel

(SCP).

If you’re using the SCP to operate or monitor the status of the unit, you may also refer to the Xanbus System Control Panel Owner’s

Guide.

LIMITATIONS ON USE

Do not use in connection with life support systems or other medical equipment or devices.


The SCP provides operating, configuration, and monitoring capability for your Xanbus system.

The SCP:

• Monitors activity throughout your onboard power system.

• Displays the latest information about your inverter/charger, battery voltage level, battery charge output, and generator start and stop activity.

• Displays the settings for each Xanbus-enabled device in the system.

• Enables you to adjust the settings for each Xanbus-enabled device in the system.

• Preserves all of its settings if system power is interrupted. After power is restored, you don’t have to reconfigure the SCP or any of the Xanbus-enabled devices connected to it.

This section provides information on operating the Freedom SW with the SCP. Please refer to the System Control Panel Owner’s

Guide for complete information on using the System Control Panel.

97-0019-01-01 19


Operating the Freedom SW with the SCP

Using the Xanbus SCP

As shown in Figure 8, the SCP has these important features:

Display screen

System information is shown on the display screen with an adjustable backlight.

Indicator LEDs

Four indicator LEDs on the front panel indicate the operating status of the Xanbus system.

Push buttons

Four push buttons allow you to select device menus and change or display settings. The red STBY/ON Fault Clear button toggles the SCP and Xanbus-enabled devices between

Operating mode and Standby (Power Save) mode, if held down for more than five seconds. The button can also be used to clear any active faults or warnings by momentarily depressing the button.

Enabling a function

When a function is enabled, it is allowed to occur but other conditions may have to be met before the function actually works. For example, the charger function on the Freedom

SW may be enabled, but will not charge the battery unless qualified

AC power is present.

Disabling a function

When a function is disabled, it is not allowed to occur and if it is already occurring, it is terminated immediately. Regardless of other conditions, the function will not work. For example, even if AC power is present, if the charger function is disabled, the Freedom SW will not charge the battery.

NOTE: All functions on the front panel can also be controlled from

the SCP.

System Control Panel

The Xanbus System Control Panel (SCP) provides configuration and monitoring capability for all Xanbus-enabled devices on the network. All changes to the configuration of the Freedom SW are made with the SCP.

The front panel of the Freedom SW provides limited control, including reset; charger enable and disable; and inverter enable and disable.

Viewing the Select Device Menu

The System Status screen displays system activity. The information appearing on the System screen varies with the status of the

inverter/charger. See “Reading the System Status Screen” on page

29. Go back to “Reading the Freedom SW Device Setup Screen” on page 30 for an explanation of the different states of the inverter/

charger. For example, Figure 17 shows the Freedom SW in the bulk

stage of charging.

The Select Device menu is where you can view a list of all the

Xanbus-enabled devices in your power system.

At least two devices are sure to appear together with System

Settings and Clock – the Freedom SW Inverter/Charger and the

Xanbus SCP. Other devices such as the Xanbus AGS and the

Freedom Sequence Intelligent Power Manager appear only when they are connected and installed.

Why use Search mode?

Search mode allows the inverter to selectively power only items that draw more than a certain amount of power, which can result in power savings. The Freedom SW has a no-load power draw of about 28 watts. Enabling search mode reduces this power draw to less than 8 watts. Search mode operates differently in single-unit and multi-unit installations.

Single units

When a single Freedom SW has search mode enabled, the inverter sends electrical search pulses through its AC output. These search pulses look for connected AC loads. The delay between search pulses is set using the Search Delay setting. After a load larger than the Search Watts setting is detected, the inverter starts producing AC output.

Double units

To use search mode in parallel stacking, the Master unit must have

Search Mode

disabled. The Slave unit must have Search Mode enabled.

When configured for 120/240-volt series stacking, each inverter/charger operates independently in search mode and attempts to detect loads connected to its terminals only.

IMPORTANT: The Slave unit continuously monitors the output of the

Master unit. If the Master unit has more than 60% of the rated load (for example, 1800 watts on Freedom SW 3012), the Slave unit will assist the

Master and the two will share the load equally. Should the load on the

Master drop below 20% of rated load (600 watts for Freedom SW 3012), the Slave unit disengages and returns to a waiting state.

97-0019-01-01 39



When to set up Search mode

The search mode feature is only valuable if the inverter can spend a fair amount of time “sleeping” each day. Therefore, if search mode is to be used it must be adjusted properly. The initial adjustment should be made so that the inverter comes on only when needed.

Certain types of loads can cause search mode to work unexpectedly.

These types of loads are described in “Inverter Applications” on page 70

.

If these kinds of loads are in the system, follow the suggestions given to eliminate the problem.

If the problem loads cannot be eliminated, there are two workaround solutions:

1.

Disable search mode from the main Freedom SW Setup menu, causing the inverter to always remain at full output voltage.

2.

Use a search-friendly companion load whose only purpose is to be switched on to wake up the inverter to power the load that is unable to bring the inverter out of search mode.

NOTES:

• Search mode, by function, cannot work with clocks and timers or devices that need power 24 hours a day. Examples of devices with timers include video recorders, coffee makers with brew timers, refrigerators, and freezers with defrost timers. Examples of devices that need power 24 hours a day include telephone answering machines, alarm systems, motion detection lights, and some thermostats.

• When the inverter is searching the output for loads, lights that have a wattage lower than this setting may flash momentarily.




Equalization Procedure

To start equalizing the batteries, do one of the following:

• Apply AC voltage and ensure that the inverter/charger transfers

AC and starts charging.

• On the Xanbus Setup menu, highlight Equalize and select

Enable .

The unit will proceed and execute a complete bulk and absorption charge before transitioning to equalize.

IMPORTANT: The inverter/charger will not perform

equalization if AC is not present, the charger is disabled, or the selected battery type does not support equalization. If any of these cases happen, a warning is issued

If the Freedom SW will not perform the equalization, see“Detected

Warning Types and Behavior” on page 73.

IMPORTANT: In a system where more than one device is capable of equalizing batteries (such as stacked Freedom SWs), there is no system-wide equalization command for all devices. To equalize with two devices, each would have to be enabled individually. Alternatively, equalization can be performed using only one device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (two-stage charging).

EXPLOSION HAZARD

Equalize charge flooded or vented batteries only. Hydrogen and oxygen gases are produced when batteries are equalize charged. Provide adequate ventilation and remove all sources of ignition to prevent explosion.

Low Battery Cut Out (LBCO) controls when the inverter stops producing AC output due to a low battery voltage condition. The inverter will stop producing AC output only after this level has been reached for the period of time set by the LBCO Delay. This setting is not temperature compensated.




Changing Freedom SW Advanced Settings

Advanced Settings menu

The advanced settings option gives you access to the full range of Freedom SW settings, including everything displayed on the basic menu. As a safeguard against unintended advanced configuration, the Xanbus SCP displays the basic settings by default. To view the advanced settings, you must

perform a special keypress (see “Selecting Advanced Settings From the Device Setup Screen” on page 46).

NOTE:

This keypress enables the advanced settings for every device in the system. After performing the keypress, Advanced Settings appears in the list and Basic Settings disappears.

FIRE AND ELECTRICAL SHOCK HAZARD

Familiarize yourself with advanced settings and the system-wide impact of changing those settings. The advanced settings are intended for qualified installation/service personnel only. Setting parameters incorrectly could damage connected equipment (such as batteries) or could severely affect the performance of your system. Incorrect charging configuration can lead to battery damage and risk of fire.

Failure to follow these instructions can result in minor or moderate injury.

The Freedom SW advanced settings include menus for configuring:

•

Inverter settings (see page 49)

•

Charger settings (see page 51)

•

AC transfer limit settings (see page 55)

•

Generator support settings (see page 56)

• Stacking operation, including customizing the default model name of the Freedom SW, and setting its network device number. Setting the device number is important when two

Freedom SWs are on the Xanbus network and sharing connections such as AC loads, utility grid, and generator. The device number is also used when configuring paralleled

Freedom SWs for Master-Slave operation (see page 57)

•

Restoring default settings (see page 61) and other advanced

features (see page 62)

Low Batt Cut Out Low Battery Cut Out (LBCO) controls when the inverter stops producing AC output due to a low battery voltage condition. The inverter will stop producing AC output only after this level has been reached for the period of time set by the LBCO Delay. This setting is not temperature compensated.

LBCO Delay

LBCO Delay controls how long the inverter is allowed to operate at or below the Low Batt Cut Out level before turning off due to a low battery voltage condition. The inverter will stop producing AC output only after the Low Batt Cut Out level has been reached for this uninterrupted period of time.

Once the inverter has shut off, the battery voltage must rise 2 volts above the Low Batt Cut Out setting (4 volts for 24-volt systems) for inverter operation to resume.

Hi Batt Cut Out Hi Batt Cut Out sets the maximum battery voltage at which the inverter will operate. If the battery voltage exceeds this limit for more than one minute, the Freedom SW displays a fault message and shuts down. The inverter will not support AC loads when in this condition. If a qualified

AC source is present, the unit passes AC through to the loads. The inverter automatically restarts when the voltage drops to 1.5 volts

(12 volt system) or 3 volts (24 volt system) below the Hi Batt Cut

Out setting. If battery voltage continues to rise after shutdown, an external charger may still be charging the batteries. The Freedom SW cannot control how external chargers operate.

Search Watts

Search Watts sets the Freedom SW’s search sensitivity when search mode is enabled. When a load larger than this setting is present, the inverter starts producing AC output. Enabling search mode from the

Setup

menu (see page 57) can minimize power draw from the battery

during periods of low demand from loads. Also see “Using Search

Mode” on page 39.

97-0019-01-01 49



Table 9 Inverter Settings Description

Item

Search Delay

Description

Search Delay sets the time between search pulses. When searching for loads, the Freedom SW sends out search pulses to determine if a load is present. If the Freedom SW finds a load above the Search Watts setting, the inverter turns on. Freedom SW power draw while in search mode decreases when Search Delay is increased, but the Freedom

SW’s response time to active loads is slower.

Using the Low Battery Cut Out and LBCO Delay Settings

The Low Batt Cut Out setting is the lowest battery voltage level acceptable for use by the inverter. When the batteries discharge to the Low Batt Cut Out setting, and are held at or below this level for the LBCO Delay time, the inverter output shuts down and transfers any available AC source (generator or grid) to the charger to bring the battery level back above the Low Batt Cut Out setting. After shutdown, the inverter does not support any AC loads, and AC loads must be powered by either a generator or utility power.

• If using an automatic generator starting system, it is recommended to set the Xanbus AGS voltage trigger setting higher than the Freedom SW Low Batt Cut Out voltage.

• Although not recommended, if using an automatic generator starting system with the start trigger set to the same voltage as the LBCO voltage, do not set the LBCO Delay to less than the amount of time it takes the generator to start and connect.

Otherwise – in both of the scenarios above – inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the Xanbus AGS from starting the generator or result in the Freedom SW cycling on and off multiple times before the generator automatically starts.

Battery Charger Functions

When AC power is available, the Freedom SW can operate as a battery charger. Different battery types and chemistries require different charging voltage levels. Not charging batteries at the required levels can shorten battery life or damage the batteries. The

Freedom SW is configured at the factory to work with the battery types recommended for inverter applications. If the default settings do not work for your specific installation, you can adjust the charge stage settings (as recommended by the battery manufacturer) on the

Custom

(Battery) Settings menu (see page 53).

NOTE: This information is provided for guidance only. Variations in battery chemistry and site-specific environmental considerations mean that you should consult your system designer or battery manufacturer for specific recommendations for appropriate battery voltage and current settings.

Gen Support

GEN Support

is basically generator support for the Freedom SW that allows power to be automatically drawn from the batteries to assist an AC generator to support heavy loads (for example, loads that exceed the available current from the generator).

Generators have a limited output current and it is possible to reach this limit when operating heavy loads. The Freedom SW is designed to assist the generator when heavy current demands load down the generator by supplying additional power from the batteries.

In addition, the battery charger can reduce its charging current to the batteries so the combined charge AC current and total load current does not exceed the capacity of the generator or trip its output breakers or fuses.

Setting the Device Name

The Dev Name setting allows you to customize the name of the

Freedom SW as it is displayed on other screens and menus.

Changing the device name is not mandatory for stacking to be successful. It simply allows a user to distinguish between two inverter/chargers that are installed in the same system.

The available characters are:

• A to Z

• a to z

• 0 to 9

• space

NOTE: Increasing the number of characters in a device name may cause other text on the same line to run off the edge of the screen. Device names should be limited to 10 characters or less.

Some examples of names are: “Master”, “Slave”, “Main”, and

“Secondary”.

To customize the Freedom SW name:

1.

After pressing Enter to select the last character of your customized device name, press Enter again to return to the menu.




Setting the Device Number

Setting the device number gives a Xanbus-enabled device a unique identity when several devices of the same type are installed in the power system network. When each identical device has a unique number, the Xanbus SCP can correctly identify and display status information for each device. A device number consists of two digits ranging from 00 (default) to 31.

If only one of each type of device is installed in the network, you do not need to set the device number. However, setting the device number to a value other than 00 is recommended in case you need to use the Restore Defaults command (which resets the device number to 00). After performing the command, checking that the device number has returned to 00 indicates that the command was successfully completed.

Battery Charging Reference

This section describes the multistage charging algorithm (formula) of the Freedom SW.

Battery Types

Freedom SW charges flooded (or wet) lead-acid, Gel, AGM

(absorbed glass mat), and custom batteries.

•

Flooded (or wet) batteries have removable battery caps for

refilling with distilled water and testing the electrolyte.

•

Gel batteries have the electrolyte in the form of a gel rather

than a liquid and do not require topping up. Gel batteries are sealed and the battery caps are not removable.

•

AGM (Absorbed Glass Mat) batteries are similar to gel

batteries except that the electrolyte is absorbed into a fiberglass matting.

•

Custom battery is configured by the dealer, factory, or service

center for battery types other than those listed above.

Charge Algorithm Stages

Three-Stage charging

If three-stage charging is enabled, the Freedom SW will charge batteries in a sequence known as three-stage charging. Whenever qualified AC power is present at the inverter’s input, it passes power through to the connected load and begins charging the batteries. The charging voltage delivered to the battery depends on the battery’s:

• Type setting

• Temperature (by switch setting or battery temperature sensor)

• State of charge

RISK OF BATTERY DAMAGE

Do not mix battery types. The Freedom SW can only select one battery type setting for all batteries connected to its bank. All connected batteries should either be: Flooded (or wet) or Gel or AGM or Custom.


The three automatic stages are:

• Bulk

• Absorption

• Float

See Figure 35 for a graph of the three-stage charging profile.

97-0019-01-01 63


Battery Charging Reference

There is a fourth stage, equalization, which is initialized manually as it is only performed occasionally and only on flooded (or wet) batteries.

The charging cycle is a multistage (three-stage) process. Whenever qualified AC power is present at the inverter’s input, it passes power through to the connected load and begins charging the batteries.

NOTE:

When the charge cycle is interrupted, the charger will restart charging at the beginning of the multistage algorithm.

Exit Current Threshold can be effectively disabled by programming the amp-hour capacity to the minimum. In this case, absorption will only exit once the Max Absorption timer expires.

Charge current during equalize state (optional state not shown here) is normally limited to 10% of the programmed amp-hour capacity setting. If this setting is programmed to the maximum, the charge current during equalize is instead limited to whatever is programmed for the maximum current limit of the unit.

Synchronized charge states are active when more than one charging device is connected in the system via the Xanbus network.

• The first unit (Freedom SW) to enter bulk, causes all other chargers to enter bulk.

• The first Freedom SW to enter absorption causes all other Freedom

SWs to enter absorption.

• The last Freedom SW ready to exit absorption triggers all Freedom

SWs to exit absorption and exit charge.

Time

Bulk Stage

Bulk charge is the first stage in the charging process and provides the batteries with a controlled, constant current. Once the battery voltage rises to the absorption voltage threshold, the charger switches to the absorption stage.

Figure 35 Three-Stage Battery Charging Cycle





During the absorption stage, the Freedom SW begins operating in constant voltage mode and the current falls gradually as the amp hours are returned to the battery. By default, the bulk and absorption voltage settings are the same for all battery types. The voltage limit settings for bulk and absorption can be adjusted independently if the battery type is set to Custom.

Once the Freedom SW reaches the Bulk (Absorption, after the first 60 minutes) Voltage setting, the Freedom SW will operate in constant voltage mode, providing only the necessary current to maintain the voltage setting. As the amp hours are returned to the battery, the current required to maintain the voltage setting falls gradually.

The Freedom SW transitions to the float stage if either one of the following two conditions are met:

1.

The charge current allowed by the batteries falls below the exit current threshold, which is equal to 2% of the programmed battery capacity (for a 500 amp-hour battery bank, this would be 10 amps), for three minutes.

2.

The Freedom SW has been in absorption for the programmed maximum absorption time limit. The default is 3 hours, but the time limit is programmable from 1 minute to 8 hours.

NOTE: If there are DC loads on the batteries, the charger’s current may never decrease to a level to initiate the next stage of charging. In this case, the charger would stay in absorption until the Absorb Time setting is reached.

NOTE: To make sure the charger does not remain in absorption for too long, adjust Absorb Time on the Charger Settings menu. The timer begins at the start of the absorption stage and terminates absorption charging if the charge current does not decrease to below 2 per cent of the battery capacity before the Absorb Time setting expires. The Absorb

Time

setting may be increased if the charge cycle continually runs the full

Absorb Time in the absence of DC loads. This is an indication of too large a battery bank for the selected Absorb Time setting.

Float Stage

Float charge maintains the batteries slightly above the self discharge voltage of the batteries. The charge current in float is the current necessary to maintain the batteries at the Float Voltage setting, limited only by the inverter's capability or other settings that limit the inverter's maximum charge rate. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and makes sure the batteries are in a constant state of readiness.

When three-stage charging is selected, the charger automatically switches to the float stage after the batteries have received a bulk

and absorption charge (see Figure 35). The batteries are maintained

97-0019-01-01 65


Battery Charging Reference at the default float voltage level for the selected battery type or the voltage selected under Float Voltage on the Custom Battery

Settings

menu.

NOTE: If the AC input fails or drops below the lower VAC limit (as set in

AC Settings ), the complete multistage charge cycle (bulk, absorption, float/no float) restarts once the source AC recovers to within the acceptable range. If the batteries are already nearly full, the charge cycle will take little time to complete.

NOTE: The battery voltage can increase above the float voltage when using an external charging device such as PV arrays, wind turbines, and micro-hydro generators. Be sure to include appropriate charge management equipment with all external DC sources.

Two-Stage Charging Process

Two-stage (or no float) mode differs from an ordinary three-stage charge mode in that it does not continuously maintain the battery at float voltage. Instead, the Freedom SW begins charging the battery in bulk mode whenever the battery voltage drops below the recharge level. While the battery voltage is above the recharge level the inverter’s AC transfer switch continues to pass power through from the utility grid to the loads, but does not actively charge the batteries.

Two-stage mode increases efficiency of utility connected systems by reducing the amount of power consumed by the inverter and batteries compared to when the battery is continuously maintained at Float Voltage. This feature can extend the life of most batteries.

Charge current during equalize state (optional state not shown here) is normally limited to 10% of the programmed amp-hour capacity setting. If this setting is programmed to the maximum, the charge current during equalize is instead limited to whatever is programmed for the max current limit of the unit.

Synchronized charge states are active when more than one charging device is connected in the system via the Xanbus network.

• The first unit to enter bulk, causes all other chargers to enter bulk.

• The first Freedom SW to enter absorption causes all other Freedom

• The last Freedom SW ready to exit absorption triggers all Freedom

SWs to exit absorption and exit charge.

97-0019-01-01


Equalize Charging

Many battery manufacturers recommend periodic equalize charging to counter cell charge imbalance and capacity-robbing electrolyte stratification. Equalizing helps to improve battery performance and lifespan by encouraging more of the battery material to become active.

Battery equalization is a controlled overcharging method that mixes up stratified electrolyte and reactivates unused areas of the plate material. Periodic equalizing can help to regularly restore batteries to a full and healthy state of charge.

Consult the battery manufacturer's recommendation for equalize charging settings. Sealed batteries should never be equalized.

Consult the battery manufacturer for optimal charging procedures when using sealed batteries.

When Equalize mode is enabled, the battery is charged from bulk to absorption, and then to the equalize phase. The Freedom SW will transition from the absorption phase to equalize if:

• the DC charge current is below 2% of the configured battery capacity (for example, 8.8A for 440Ah)

• the absorption time is exceeded (for example, 180 min)

After absorption, the maximum charge DC current is set to 10% of

battery capacity (for example, 44A for 440Ah). See Figure 37. This

constant current charge will continue until the voltage has increased to the equalize voltage at which point the battery will be regulated at the temperature-compensated equalize voltage.

67



If the battery capacity is set to zero (Ah=0 effectively disables the exit current criteria for the absorption charge stage making the absorption stage defined by time only), the equalize charge current is fixed at maximum 100% of the charge rate.

Equalization duration is fixed at one hour.

Troubleshooting

Inverter Applications

The Freedom SW performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section.

Resistive Loads

Resistive loads are the easiest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another. Resistive loads generate heat in order to accomplish their tasks. Toasters, coffee pots, and incandescent lights are typical resistive loads. It is usually impractical to run larger resistive loads—such as electric stoves and water heaters—from an inverter due to their high current requirements. Even though the inverter may be able to accommodate the load, the size of battery bank will limit inverter run time.

the maximum surge current rating of the inverter. Since motor characteristics vary, only testing will determine whether a specific load can be started and how long it can be run.

If a motor fails to start within a few seconds or loses power after running for a time, it should be turned off. When the inverter attempts to start a load that is greater than it can handle, the inverter may shut down from an AC overload fault.

Problem Loads

Very Small Loads

If the power consumed by a device is less than the threshold of the search mode circuitry, and search mode is enabled, the inverter will not run. Most likely the solution will be to disable Search mode or lower the sense threshold.

Motor Loads

Induction motors (AC motors without brushes) require up to six times their running current on startup. The most demanding are those that start under load (for example, compressors and pumps).

Of the capacitor start motors (typical in drill presses and band saws, for example), the largest you can expect to run is one horsepower.

Universal motors are generally easier to start. Check that the

Locked Rotor Amps (LRA) rating of the motor load does not exceed

Fluorescent Lights and Power Supplies

Some devices cannot be detected when scanned by search mode circuitry. Small fluorescent lights are the most common example. Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads, either a small companion load like a light bulb rated for more than the Search

Watts

setting must be used to bring the inverter out of search mode, or the inverter may be programmed to remain on by disabling

Search

mode. (See “Using Search Mode” on page 39.)



Clocks

You may notice that your clocks are not accurate. Some of the clocks on your appliances may reset when the Freedom SW is in search mode.

Searching

When the inverter is in search mode, it may fail to start some loads even though the rated wattage on the load is more than the Search Watts setting. Disable Search or apply an additional load (companion load) to make the inverter exit search mode.

Troubleshooting

Troubleshooting the Freedom SW via the SCP

The Freedom SW is designed with a number of protection features to provide efficient operation. If, however, you have any problems operating your inverter/charger read this troubleshooting chapter.

If you cannot resolve the problem, record the information about your system. This information will help your dealer or customer service to assist you better when you contact them.

Detected Fault Types

There are three types of detected fault messages: automatic faults,

manual faults, and escalating automatic faults. Table 1 describes

how they differ in their behavior and how you can respond to them when they appear on the SCP.

ELECTRICAL SHOCK HAZARD

Do not disassemble the inverter/charger. The Freedom SW contains no user-serviceable parts.


When a detected fault or warning message appears, you can acknowledge the message to clear the screen. To acknowledge a fault or warning message, press the Enter button on the SCP. This action does not clear the fault or warning condition, so you should

consult “Detected Fault Messages” on page 74 and “Detected

Warning Messages” on page 80 for suggested actions after you have

acknowledged the message. Refer to the Xanbus System Control

Panel Owner’s Guide for more information on detected faults and warnings.

Table 1 Detected Fault Types and Behaviors

Fault type Behavior

Automatic fault

Manual fault

Clears automatically if the detected condition that generated the message goes away. You can also acknowledge automatic faults without waiting for them to clear automatically.

Requires you to clear it by:

• Selecting Clear Faults on the Freedom SW or on the device that generated the detected fault (if the condition still exists, the fault message reappears).

• Correcting the condition that detected the fault.



Table 1 Detected Fault Types and Behaviors

Fault type Behavior

Escalating automatic faults

Clears automatically if the detected fault condition goes away, just like an automatic fault.

However, if an escalating automatic fault occurs several times within a defined time period, the escalating automatic fault becomes a manual fault, requiring user intervention. For example, if three detected faults occur in one minute, it will no longer clear itself but becomes a manual fault. Then, you must identify the problem, correct the condition that detected the fault, and clear the fault or reset the device.

Troubleshooting

Detected Warning Types

There are two types of detected warnings: automatic and manual.

When the Freedom SW detects a warning condition, it displays a warning message on the SCP.

Table 2 describes how they differ in their behavior and in how you

can respond to them when they appear on the SCP.

Table 2 Detected Warning Types and Behavior

Warning type

Automatic warning

Manual warning

Behavior

Clears automatically if the detected condition that generated the message goes away. You can also acknowledge automatic warnings without waiting for them to clear automatically.

Requires you to acknowledge it before you can proceed with configuring or operating the

Freedom SW. Manual warnings are usually in the form of a Yes/No question that you may acknowledge by pressing the Enter button on the SCP for Yes and the Func button for No.
