2. DESCRIPTION
2.1 General
Multi Compact -functional
The MultiPlus Compact gets its name from the multiple functions it can perform. It is a
powerful true sine wave inverter, a sophisticated battery charger that features adaptive
charge technology and a high-speed AC transfer switch in a single compact enclosure.
Beside these primary functions, however, the MultiPlus Compact has several advanced
features that provide a range of new applications as outlined below.
Uninterrupted AC power
In the event of a grid failure, or shore or generator power being disconnected, the inverter
within the Multi Compact is automatically activated and takes over supply to the connected
loads. This happens so fast (less than 20 milliseconds) that computers and other electronic
equipment will continue to operate without disruption.
PowerControl – Dealing with limited generator or shore side power
With a Phoenix Multi Control Panel a maximum generator or shore current can be set. The
Multi Compact will then take account of other AC loads and use whatever is extra for
charging, thus preventing the generator or shore supply from being overloaded.
PowerAssist – Boosting the capacity of shore or generator power
This feature takes the principle of PowerControl to a further dimension allowing the MultiPlus
Compact to supplement the capacity of the alternative source. Where peak power is so often
required only for a limited period, it is possible to reduce the size of generator needed or
conversely enable more to be achieved from the typically limited shore connection. When the
load reduces, the spare power is used to recharge the battery.
Programmable relay
The MultiPlus is equipped with a programmable relay that by default is set as an alarm relay.
The relay can be programmed for all kinds of other applications however, for example as a
starter relay for a generator.
2.2 Battery charger
Adaptive 4-stage charging characteristics: bulk – absorption – float – storage
The microprocessor-driven adaptive battery management system can be adjusted for various
types of batteries. The adaptive function automatically adapts the charging process to battery
use.
The right amount of charge: variable absorption time
In the event of slight battery discharge, absorption is kept short to prevent overcharging and
excessive gas formation. After deep discharging, the absorption time is automatically
extended in order to fully charge the battery.
Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, damage due to excessive gassing will be prevented by
Appendix
Less maintenance and aging when the battery is not in use: the Storage
mode
The Storage mode kicks in whenever the battery has not been subjected to
discharge during 24 hours. In the Storage mode float voltage is reduced to
2,2V/cell (13,2V for 12V battery) to minimise gassing and corrosion of the
positive plates. Once a week the voltage is raised back to the absorption level to
‘equalize’ the battery. This feature prevents stratification of the electrolyte and
sulphation, a major cause of early battery failure.
EN
automatically limiting the rate of voltage increase once the gassing voltage has
been reached.
Two DC outputs for charging two batteries
The main DC terminal can supply the full output current. The second output, intended for
charging a starter battery, is limited to 4A and has a slightly lower output voltage.
Increasing service life of the battery: temperature compensation
The temperature sensor (supplied with the product) serves to reduce charging voltage when
battery temperature rises. This is particularly important for maintenance-free batteries, which
could otherwise dry out by overcharging.
More on batteries and charging
Our book ‘Energy Unlimited’ offers further information on batteries and battery charging, and
is available free of charge on our website (see www.victronenergy.com -> Support &
Downloads’ -> General Technical Information). For more information on adaptive charging,
please also refer to the General Technical Information our website.
2.3 Self consumption – solar energy storage systems
When the Multi/Quattro is used in a configuration in which it will feed back energy to the grid
it is required to enable grid code compliance by selecting the grid code country setting with
the VEConfigure tool.
This way the Multi/Quattro can comply to the local rules.
Once set, a password will be required to disable grid code compliance or change grid code
related parameters.
If the local grid code is not supported by the Multi/Quattro an external certified interface
device should be used to connect the Multi/Quattro to the grid.
Special note for Australian customers: IEC62109.1 certification and CEC approval for off-grid
use does NOT imply approval for grid-interactive installations. Additional certification to IEC
62109.2 and AS 4777.2.2015 are required before grid-interactive systems can be
implemented. Please check Clean Energy Council website for current approvals.
3. OPERATION
3.1 On/Off/Charger Only Switch
When switched to "on", the product is fully functional. The inverter will come into operation
and the LED "inverter on" will light up.
An AC voltage connected to the "AC in" terminal will be switched through to the "AC out"
terminal, if within specifications. The inverter will switch off, the "mains on" LED will light up
and the charger commences charging. The "bulk", "absorption" or "float" LEDs will light up,
depending on the charger mode.
If the voltage at the "AC-in" terminal is not within specifacations, the inverter will switch on.
When the switch is switched to "charger only", only the battery charger of the Phoenix Multi
will operate (if mains voltage is present). In this mode input voltage also is switched through
to the "AC out" terminal.
NOTE: When only the charger function is required, ensure that the switch is switched to
"charger only". This prevents the inverter from being switched on if the mains voltage is lost,
thus preventing your batteries from running flat.
3.2 Remote control
Remote control is possible with a 3-way switch or with a Multi Control panel.
The Multi Control panel has a simple rotary knob with which the maximum current of the AC
input can be set: see PowerControl and PowerAssist in Section 2.
For the appropriate DIP switch settings, see sect. 5.5.1.
3.3 Equalisation and forced absorption
3.3.1 Equalisation
Traction batteries may require regular equalisation charging. In the equalisation mode, the
MultiPlus will charge with increased voltage for one hour (1V above the absorption voltage
for a 12V battery, 2V for a 24V battery). The charging current is then limited to 1/4 of the set
value. The “bulk” and “absorption” LEDs flash intermittently.
Equalisation mode supplies a higher charging voltage than most DC consuming
devices can cope with. These devices must be disconnected before additional
charging takes place.
3.3.2 Forced absorption
Under certain circumstances, it can be desirable to charge the battery for a fixed time at
absorption voltage level. In Forced Absorption mode, the MultiPlus will charge at the normal
absorption voltage level during the set maximum absorption time. The “absorption” LED will
be ‘on’.
Appendix
If the switch is not in the required position after following this procedure, it can be
switched over quickly once. This will not change the charging state.
EN
3.3.3 Activating equalisation or forced absorption
The MultiPlus can be put into both these states from the remote panel as well as
with the front panel switch, provided that all switches (front, remote and panel)
are set to “on” and no switches are set to “charger only”.
In order to put the MultiPlus in this state, the procedure below should be followed.
NOTE: Switching from “on” to “charger only” and vice versa, as described below, must be
done quickly. The switch must be toggled such that the intermediate position is 'skipped', as
it were. If the switch remains in the “off” position even for a short time, the device may be turned off. In that
case, the procedure must be restarted at step 1. A certain degree of familiarisation is required when using
the front switch on the Compact in particular. When using the remote panel, this is less critical.
Procedure:
1.
2.
3.
4.
5.
6.
Check whether all switches (i.e. front switch, remote switch or remote panel switch if present)
are in the “on” position.
Activating equalisation or forced absorption is only meaningful if the normal charging cycle is
completed (charger is in 'Float').
To activate:
a. Switch rapidly from “on” to “charger only” and leave the switch in this position for ½ to 2
seconds.
b. Switch rapidly back from “charger only” to “on” and leave the switch in this position for ½ to
2 seconds.
c. Switch once more rapidly from “on” to “charger only” and leave the switch in this position.
On the MultiPlus the three LEDs “Inverter”, “Charger” and “Alarm” will now flash 5 times.
If a MultiControl panel is connected, on the panel the LEDs “bulk”, “absorption” and “float” will
also flash 5 times.
Subsequently, on the MultiPlus the LEDs “Bulk”, “Absorption” and “Float” will each light during
2 seconds.
If a MultiControl panel is connected, on the panel the LEDs “bulk”, “absorption” and “float” will
also each light during 2 seconds.
a. If the switch on the MultiPlus is set to “on” while the “Bulk” LED lights, the charger will switch
to equalisation.
Similarly, if the switch on the MultiControl panel is set to “on” while the “Bulk” LED lights, the
charger will switch to equalisation.
b. If the switch on the MultiPlus is set to “on” while the “Absorption” LED lights, the charger will
switch to forced absorption.
Similarly, if the switch on the MultiControl panel is set to “on” while the “Absorption” LED lights,
the charger will switch to forced absorption.
c. If the switch on the MultiPlus is set to “on” after the three LED sequence has finished, the
charger will switch to “Float”.
Similarly, if the switch on the MultiControl panel is set to “on” after the three LED sequence
has finished, the charger will switch to “float”.
d. If the switch is has not been moved, the MultiPlus will remain in ‘charger only’ mode and
switch to “Float”.

4. INSTALLATION
This product should be installed by a qualified electrician.
4.2 Location
The product must be installed in a dry and well-ventilated area, as close as possible to the
batteries. There should be a clear space of at least 10cm around the appliance for cooling.
Excessively high ambient temperature will result in the following:
Reduced service life.
Reduced charging current.
Reduced peak capacity, or shutdown of the inverter.
Never mount the appliance directly above the batteries.
The product is suitable for wall mounting. For mounting see appendix A.
The appliance can be mounted horizontally as well as vertically; vertical mounting is
preferable. The vertical position offers optimum cooling.
The interior of the product must remain accessible after installation.
Try and keep the distance between the product and the battery to a minimum in order to
minimize cable voltage losses.
For safety purposes, this product should be installed in a heat-resistant
environment if it is used with equipment where a substantial amount of power is
to be converted. You should prevent the presence of e.g. chemicals, synthetic
components, curtains or other textiles, etc., in the immediate vicinity.

Appendix
In order to fully utilize the full capacity of the product, batteries with sufficient
capacity and battery cables with sufficient cross section should be used. See
table.
Remark: Internal resistance is the important factor when working with low capacity batteries.
Please consult your supplier or the relevant sections of our book “electricity on board”,
downloadable from our website.
Procedure
Proceed as follows to connect the battery cables:
Use an insulated box spanner in order to avoid shorting the battery.
Avoid shorting the battery cables.
Connect the battery cables: the + (red) on the left and the - (black) on the right, to the
battery see appendix A.
Reverse polarity connection (+ to – and – to +) will cause damage to the product. (Safety
fuse inside the Multi Compact can be damaged)
Secure the nuts tightly in order to reduce the contact resistance as much as possible.
4.3 Connection of the AC cabling
This is a Safety Class I product (supplied with a protective grounding terminal).
Uninterruptible protective grounding must be provided at the AC input
and/or output terminals and/or chassis grounding point located externally
on the product.
The MultiPlus is provided with a ground relay (relay H, see appendix B) that
automatically connects the Neutral output to the chassis if no external AC
supply is available. If an external AC supply is provided, the ground relay H will
open before the input safety relay closes. This ensures the correct operation of
an earth leakage circuit breaker that is connected to the output.
─
In a fixed installation, an uninterruptable grounding can be secured by
means of the grounding wire of the AC input. Otherwise the casing must
be grounded.
─
In a mobile installation (for example, with a shore current plug), interrupting
the shore connection will simultaneously disconnect the grounding
connection. In that case, the casing must be connected to the chassis (of
the vehicle) or to the hull or grounding plate (of the boat).
In case of a boat, direct connection to the shore ground is not recommended
because of potential galvanic corrosion. The solution to this is using an isolation
transformer.
The mains -input & output terminal connector can be found on the bottom of the Multi
Compact, see appendix A.
•
•
AC-in
The AC input must be protected by a fuse or magnetic circuit breaker rated at 50A
or less, and cable cross-section must be sized accordingly. If the input AC supply
is rated at a lower value, the fuse or magnetic circuit breaker should be down sized
accordingly.
AC-out
With its PowerAssist feature the Multi can add up to 2kVA (that is 2000 / 120 = 17A) to
the output during periods of peak power requirement. Together with a maximum input
current of 50A this means that the output can supply up to 50 + 17 = 67A.
An earth leakage circuit breaker and a fuse or circuit breaker rated to support the
expected load must be included in series with the output, and cable cross-section
must be sized accordingly.
EN
4.4 Optional Connections
4.4.1 Second Battery
The MultiPlus Compact has a connection (+) for charging a starter battery. For
connection see appendix A.
Appendix
A number of optional connections are possible:
Undo the four screws at the front of the enclosure and remove the front panel.
4.4.2 Temperature Sensor
The temperature sensor supplied with the product may be used for temperaturecompensated charging. The sensor is insulated and must be mounted on the batteries minus
pole. Default output voltages for Float and Absorption are at 25°C. In adjust mode
temperature compensation is disabled.

4.4.3 Remote Control
The product can be remotely controlled in two ways:
- With an external 3-way switch
- With a Multi Control Panel
Please see section 5.5.1. for appropriate DIP switch settings.
4.4.4. Programmable relay
The MultiPlus is equipped with a multi-functional relay that by default is programmed as an
alarm relay. The relay can be programmed for all kinds of other applications however, for
example to start a generator (VEConfigure software needed).
Near the connection terminals an LED illuminates when the relay is activated (refer to S, see
appendix A).
4.4.5 Parallel Connection
The MultiPlus can be connected in parallel with several identical devices. To this end, a
connection is established between the devices by means of standard RJ45 UTP cables. The
system (one or more Multis plus optional control panel) will require subsequent configuration
(see Section 5).
In the event of connecting MultiPlus units in parallel, the following requirements must be met:
•
A maximum of six units connected in parallel.
•
Only identical devices may be connected in parallel.
•
The DC connection cables to the devices must be of equal length and cross-section.
•
If a positive and a negative DC distribution point is used, the cross-section of the connection
•
•
•
•
•
•
between the batteries and the DC distribution point must at least equal the sum of the required
cross-sections of the connections between the distribution point and the MultiPlus units.
Place the MultiPlus units close to each other, but allow at least 10 cm for ventilation purposes under,
above and beside the units.
UTP cables must be connected directly from one unit to the other (and to the remote panel).
Connection/splitter boxes are not permitted.
A battery-temperature sensor need only be connected to one unit in the system. If the temperature
of several batteries is to be measured, you can also connect the sensors of other MultiPlus units in
the system (with a maximum of one sensor per MultiPlus). Temperature compensation during
battery charging responds to the sensor indicating the highest temperature.
Voltage sensing must be connected to the master (see Section 5.5.1.4).
If more than three units are connected in parallel in one system, a dongle is required (see
Section 5).
Only one remote control means (panel or switch) can be connected to the system.
4.4.6 Three-phase operation
The MultiPlus can also be used in 3-phase wye (Y) configuration. To this end, a connection
between the devices is made by means of standard RJ45 UTP cables (the same as for
parallel operation). The system (Multis plus an optional control panel) will require
subsequently configuration (see Section 5).
Pre-requisites: see Section 4.4.6.
Note: the MultiPlus is not suitable for 3-phase delta (Δ) configuration.
5.1 Standard settings: ready for use
On delivery, the MultiPlus is set to standard factory values. In general, these
settings are suitable for single-unit operation.
Appendix
Settings may only be changed by a qualified engineer
Carefully read the instructions before changes are made.
Batteries should be placed in a dry and well-ventilated area during
charging.

5.2 Explanation of settings
Settings that are not self-explanatory are described briefly below. For further information,
please refer to the help files in the software configuration programs (see Section 5.3).
Inverter frequency
Output frequency if no AC is present at the input.
Adjustability: 50Hz; 60Hz
Input frequency range
Input frequency range accepted by the MultiPlus. The MultiPlus synchronises within this
range with the AC input frequency. The output frequency is then equal to the input
frequency.
Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz
Input voltage range
Voltage range accepted by the MultiPlus. The MultiPlus synchronises within this range with
the AC input voltage. The output voltage is then equal to the input voltage.
Adjustability:
Lower limit: 94 - 120V
Upper limit: 120 - 143V
Inverter voltage
Output voltage of the MultiPlus in battery operation.
Adjustability: 95 – 128V
Stand-alone / parallel operation / 2-3 phase setting
Using several devices, it is possible to:
•
increase total inverter power (several devices in parallel)
•
create a split-phase system
•
create a 3-phase system.
The standard product settings are for standalone operation. For parallel, three phase or split
phase operation see section 4.4.5 and 4.4.6.
Search Mode (Applicable in stand-alone configuration only)
If search mode is ‘on’, the power consumption in no-load operation is decreased by approx.
70%. In this mode the Compact, when operating in inverter mode, is switched off in case of
no load or very low load, and switches on every two seconds for a short period. If the output
current exceeds a set level, the inverter will continue to operate. If not, the inverter will shut
down again.
The Search Mode can be set with a DIP switch.
The Search Mode “shut down” and “remain on” load levels can be set with VEConfigure.
The standard settings are:
Shut down: 40 Watt (linear load)
Turn on: 100 Watt (linear load)
EN
Appendix
AES (Automatic Economy Switch)
Instead of the search mode, the AES can also be chosen (with help of
VEConfigure only).
If this setting is turned ‘on’, the power consumption in no-load operation and with
low loads is decreased by approx. 20%, by slightly 'narrowing' the sinusoidal
voltage. Not adjustable with DIP switches. Applicable in stand-alone configuration
only.
Ground relay (see appendix B)
With this relay (H), the neutral conductor of the AC output is grounded to the
chassis when the back feed safety relay is open. This ensures the correct
operation of earth leakage circuit breakers in the output.
If a non-grounded output is required during inverter operation, this function must be turned
off. (See also Section 4.5)
Not adjustable with DIP switches.
Battery charge curve
The standard setting is ‘Four-stage adaptive with BatterySafe mode’. See Section 2 for a
description.
This is the recommended charge curve. See the help files in the software configuration
programs for other features.
Battery type
The standard setting is the most suitable for Victron Gel Deep Discharge, Gel Exide A200,
and tubular plate stationary batteries (OPzS). This setting can also be used for many other
batteries: e.g. Victron AGM Deep Discharge and other AGM batteries, and many types of
flat-plate open batteries. Four charging voltages can be set with DIP switches.
Automatic equalisation charging
This setting is intended for tubular plate traction batteries. During absorption the voltage limit
increases to 2,83V/cell (34V for a 24V battery) once the charge current has tapered down to
less than 10% of the set maximum current.
Not adjustable with DIP switches.
See ’tubular plate traction battery charge curve’ in VEConfigure.
Absorption time
The absortion time depends on the bulk time (adaptive charge curve), so that the battery is
optimally charged. If the ‘fixed’ charging characteristic is selected, the absorption time is
fixed. For most batteries, a maximum absorption time of eight hours is suitable. If an extra
high absorption voltage is selected for rapid charging (only possible for open, flooded
batteries!), four hours is preferable. With DIP switches, a time of eight or four hours can be
set. For the adaptive charge curve, this determines the maximum absorption time.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Section 2. Not adjustable with DIP switches.
Bulk Protection
When this setting is ‘on’, the bulk charging time is limited to 10 hours. A longer charging time
could indicate a system error (e.g. a battery cell short-circuit). Not adjustable with DIP
switches.
AC input current limit
These are the current limit settings at which PowerControl and PowerAssist come into
operation. The factory setting is 30A.
See Section 2, the book 'Energy Unlimited', or the many descriptions of this unique feature
on our website www.victronenergy.com .
Remark: lowest allowable current setting for PowerAssist: 11A.
(11A per unit in case of parallel operation)
UPS feature
If this setting is ‘on’ and AC on the input fails, the MultiPlus switches to inverter operation
practically without interruption. The MultiPlus can therefore be used as an Uninterruptible
Power Supply (UPS) for sensitive equipment such as computers or communication systems.
The output voltage of some small generator sets is too unstable and distorted for using this
setting* – the MultiPlus would continually switch to inverter operation. For this reason, the
setting can be turned off. The MultiPlus will then respond less quickly to AC input voltage
deviations. The switchover time to inverter operation is consequently slightly longer, but most
equipment (most computers, clocks or household equipment) is not adversely impacted.
Recommendation: Turn the UPS feature off if the MultiPlus fails to synchronise, or
continually switches back to inverter operation.
*In general, the UPS setting can be left ‘on’ if the MultiPlus is connected to a generator with a
‘synchronous AVR regulated alternator’.
The UPS mode may have to be set to ‘off’ if the MultiPlus is connected to a generator with a
‘synchronous capacitor regulated alternator’ or an asynchronous alternator.
Dynamic current limiter
Intended for generators, the AC voltage being generated by means of a static inverter (socalled ‘inverter’ generators). In these generators, rpm is down-controlled if the load is low:
this reduces noise, fuel consumption and pollution. A disadvantage is that the output voltage
will drop severely or even completely fail in the event of a sudden load increase. More load
can only be supplied after the engine is up to speed.
If this setting is ‘on’, the MultiPlus will start supplying extra power at a low generator output
level and gradually allow the generator to supply more, until the set current limit is reached.
This allows the generator engine to get up to speed.
This setting is also often used for ‘classic’ generators that respond slowly to sudden load
variation.
EN
Appendix
WeakAC
Strong distortion of the input voltage can result in the charger hardly operating or
not operating at all. If WeakAC is set, the charger will also accept a strongly
distorted voltage, at the cost of greater distortion of the input current.
Recommendation: Turn WeakAC on if the charger is hardly charging or not
charging at all (which is quite rare!). Also turn on the dynamic current limiter
simultaneously, and reduce the maximum charging current to prevent
overloading the generator if necessary.
Not adjustable with DIP switches.
BoostFactor
Change this setting only after consulting with Victron Energy or with an engineer trained by
Victron Energy!
Not adjustable with DIP switches.
Programmable relay
By default, the programmable relay is set as an alarm relay, i.e. the relay will de-energise in
the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the input almost too
high, battery voltage almost too low).
Not adjustable with DIP switches.
Near the connection terminals an LED illuminates when the relay is activated (refer to S, see
appendix A).
VEConfigure software
With VEConfigure software the relay can also be programmed for other purposes, for
example to provide a generator starting signal.
With VEConfigure, several other special application modes of operation can be programmed.
Example: A house or an office connected to the public mains, fitted with solar panels with
energy storage in batteries.
The batteries are used to prevent return delivery to the mains. During the day, redundant
solar energy is stored in batteries. This energy is used in the evenings and at night. An
energy shortfall is compensated by the mains. The MultiPlus converts the battery DC voltage
to AC. The power is always less than or equal to the power consumption, so that return
delivery to the mains does not occur. In the event of mains failure, the MultiPlus isolates the
premises from the mains, which become autonomous (self-sufficient). In this way, a solar
energy installation or a combined micro-scale heating and power plant can be economically
used in areas with an unreliable mains supply and/or financially unfavourable energy-return
conditions.
5.3 Configuration by computer
All settings can be changed by means of a computer or with a VE.Net panel (except for the
multi-functional relay and the VirtualSwitch when using VE.Net).
Some settings can be changed with DIP switches (see Section 5.2).
For changing settings with the computer, the following is required:
•
VEConfigure3 software: can be downloaded free of charge at
www.victronenergy.com.
•
A MK3-USB (VE.Bus to USB) interface.
Alternatively, the Interface MK2.2b (VE.Bus to RS232) can be used (RJ45 UTP
cable needed).
5.3.1 VE.Bus Quick Configure Setup
VE.Bus Quick Configure Setup is a software program with which systems with a maximum
of three MultiPlus units (parallel or three phase operation) can be configured in a simple
manner.
The software can be downloaded free of charge at www.victronenergy.com .
5.3.2 VE.Bus System Configurator
For configuring advanced applications and/or systems with four or more MultiPlus units,
VE.Bus System Configurator software must be used. The software can be downloaded
free of charge at www.victronenergy.com .
5.4 Configuration with a VE.Net panel
To this end, a VE.Net panel and the VE.Net to VE.Bus converter are required.
With VE.Net all parameters are accessible, with the exception of the programmable relay and
some other advanced settings.
Some settings can be changed with DIP switches
Appendix
Procedure:
a) Turn the Compact on, preferably without load and without AC voltage on the
inputs. The Compact will then operate in inverter mode.
b) Set the dipswitches as required.
c) Store the settings by moving Dip switch 8 to “on” and back to “off”.

5.5 Configuration with DIP switches
5.5.1. DIP switch 1 and 2
Default setting: to operate the product with the “On/Off/Charger Only” switch
ds 1: “off”
ds 2: “on”
The default setting is required when using the “On/Off/Charger Only” switch in the front
panel.
Setting for remote operation with a Multi Control Panel:
ds 1: “on”
ds 2: “off”
This setting is required when a Multi Control Panel is connected.
The Multi Control panel must be connected to one of the two RJ48 sockets B, see appendix
A.
Setting for remote operation with a 3-way switch:
ds 1: “off”
ds 2: “off”
This setting is required when a 3-way switch is connected.
The 3-way switch must be wired to terminal L, see appendix A.
Only one remote control can be connected, i.e. either a switch or a remote control
panel.
In both cases the switch on the product itself should be “on”.
5.5.2. DIP switch 3 to 7
These DIP switches can be used to set:
- Battery charge voltage and Absorption time
- Inverter frequency
- Search mode
- AC input current limit 30A or 50A

Batteries with high antimony content can typically be charged with a lower absorption voltage
than batteries with low antimony content. (Please refer to our book “Electricity on Board”
downloadable from our website www.victronenergy.com for details and suggestions about
charging batteries). Contact your battery supplier for the correct charge voltages and change
(with VE-configure) the voltage settings if required.
The default charge current setting is 75% of the maximum charge current. This current will
be too high for most applications.
For most battery types the optimal charge current is 0.1-0.2x the battery capacity.

Bulk-mode: Entered when charger is started. Constant current is applied until the gassing voltage is reached (14.4V
resp. 28.8V, temperature compensated).
Battery Safe Mode: If, in order to quickly charge a battery, a high charge current in combination with a high absorption
voltage has been chosen, the Multi Compact / MultiPlus Compact will prevent damage due to excessive gassing by
automatically limiting the rate of voltage increase once the gassing voltage has been reached.The Battery Safe Mode is
part of the calculated absorption time.
Absorption-mode: A constant voltage period to fully charge the battery. The absorption time is equal to 20x bulk time
or the set maximum absorption time, whichever comes first.
Float-mode: Float voltage is applied to keep the battery fully charged and to protect it against self-discharge.Reduced
Float: After one day of Float charge a reduced Float charge is applied. This is 13,2V resp. 26,4V (for 12V and 24V
charger). This will limit water loss to a minimum when the battery is stored for the winter season.After an adjustable
time (default = 7 days) the charger will enter Repeated Absorption-mode for an adjustable time (default = 1 hour).
