Victron Multiplus-II 3000VA 12V Inverter With 120A Charger 12/3000/120-32 230V

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 current sensor 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 (not available for the 8k and 10k models)

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: Cerbo GX,
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 Cerbo 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.
