A MultiPlus, plus ESS (Energy Storage System) functionality
The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external
currentsensor option which extends the PowerControl and PowerAssist function to 50A resp. 100A.
The MultiPlus-II is ideally suited for professional marine, yachting, vehicle and land based off-grid applications.
It also has built-in anti-islanding functionality, and an increasingly long list of country approvals for ESS application.
Several system configurations are possible. For more detailed information see the ESS Design and configuration manual.
PowerControl and PowerAssist – Boosting the capacity of the grid or a generator
A maximum grid or generator current can be set. The MultiPlus-II will then take account of other AC loads and use
whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl
function).
PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a
limited period, the MultiPlus-II will compensate insufficient generator, shore or grid power with power from the battery.
When the load reduces, the spare power is used to recharge the battery.
Solar energy: AC power available even during a grid failure
The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is
compatible with both solar charger controllers and grid-tie inverters.
Two AC Outputs
The main output has no break functionality. The MultiPlus-II takes over the supply to the connected loads in the event of
a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that
computers and other electronic equipment will continue to operate without disruption.
The second output is live only when AC is available on the input of the MultiPlus-II. Loads that should not discharge the
battery, like a water heater for example, can be connected to this output.
Virtually unlimited power thanks to parallel and three phase operation
Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/5000/70 units, for example, will provide
25 kW / 30 kVA output power with 420 Amps charging capacity.
In addition to parallel connection, three units of the same model can be configured for three phase output. But that’s not
all: up to 6 sets of three units can be parallel connected for a 75 kW / 90 kVA inverter and more than 1200 Amps charging
capacity.
On-site system configuring, monitoring and control
Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface
needed).
Several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer,
Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, Digital Multi Control Panel.
Remote configuring and monitoring
Install a Color Control GX or other GX product to connect to the internet.
Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
When connected to the internet, systems can be accessed remotely, and settings can be changed.

The second output is live only when AC is available on the input of the MultiPlus. Loads that should not
discharge the battery, like a water heater for example can be connected to this output (second output available
on models rated at 3 kVA and more).
Virtually unlimited power thanks to parallel operation
Up to 6 Multis can operate in parallel to achieve higher power output. Six 24/5000/120 units, for example, will
provide 25 kW / 30 kVA output power with 720 Amps charging capacity.
Three phase capability
In addition to parallel connection, three units of the same model can be configured for three phase output. But
that’s not all: up to 6 sets of three units can be parallel connected for a huge 75 kW / 90 kVA inverter and more
than 2000 Amps charging capacity.
PowerControl – Dealing with limited generator, shore side or grid power
The MultiPlus is a very powerful battery charger. It will therefore draw a lot of current from the generator or
shore side supply (nearly 10 A per 5 kVA Multi at 230 VAC). With the Multi Control Panel a maximum generator
or shore current can be set. The MultiPlus 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. It allows the MultiPlus to supplement
the capacity of the alternative source. Where peak power is so often required only for a limited period, the
MultiPlus will make sure that insufficient shore or generator power is immediately compensated for by power
from the battery. When the load reduces, the spare power is used to recharge the battery.
Solar energy: AC power available even during a grid failure
The MultiPlus can be used in off grid as well as grid connected PV and other alternative energy systems.
Loss of mains detection software is available.
System configuring
– In case of a stand-alone application, if settings have to be changed, this can be done in a matter of
minutes with a DIP switch setting procedure.
– Parallel and three phase applications can be configured with VE.Bus Quick Configure and VE.Bus System
Configurator software.
– Off grid, grid interactive and self-consumption applications, involving grid-tie inverters and/or MPPT
Solar Chargers can be configured with Assistants (dedicated software for specific applications).
On-site Monitoring and control
Several options are available: Battery Monitor, Multi Control Panel, Color Control GX or other GX devices,
smartphone or tablet (Bluetooth Smart), laptop or computer (USB or RS232).
Remote Monitoring and control
Color Control GX or other GX devices.
Data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
Remote configuring
When connected to the Ethernet, systems with a Color Control GX or other GX device can be accessed and
settings can be changed remotely.
