Victron MultiPlus-II 12VDC/3000VA/120-50 Inverter/Charger - 2 X 120V Model

New from Victron Energy: The MultiPlus-II 12VDC/3KVA/120-50 2x120V Inverter/Charger!

Please note that this is a complex product, and should only be installed by reputable, experienced, Victron-trained systems installers.

120/240V input and output or 120V input and output (always 120V output when in inverter mode)

The AC input can be supplied from a split-phase 120/240V source, or single-phase 120V source.

The MultiPlus-II switches to inverter operation when no AC source is available. The inverter output is 120V single-phase. If split-phase 120/240 is required from inverted power, two MultiPlus-II units may be connected in parallel split-phase mode just like the MultiPlus and Quattro line of inverter/chargers.

In invert mode, the MultiPlus connects both output lines (L1 and L2) together to provide 120V to loads on either line. Any 240V loads will therefore be supplied only when the MultiPlus-II is supplied by a split-phase AC source. This prevents heavy 240V loads such as water heaters or air conditioners from discharging the battery.

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 (available on L1 input only).

Two AC Outputs

The main output has no-break functionality (UPS function). The MultiPlus-II takes over the supply to the connected 120V loads in the event of a grid failure or when shore/generator power is disconnected. The transfer time of the L1 output is less than 18 milliseconds so that computers and other electronic equipment will continue to operate without disruption.

The transfer time of the L2 output is longer: approximately 40 milliseconds.

The second (auxiliary) output is live only when AC is available on the input of the MultiPlus-II. Loads that should not discharge the battery can be connected to this output.

Virtually unlimited power thanks to parallel and three phase operation

Up to 6 MultiPlus-II units can operate in parallel to achieve higher power output.

In addition to parallel connection, three units of the same model can be configured for three-phase output.

In multi-phase setups, L2 is disabled on all units.

On-site system configuring, monitoring and control

Settings can be changed in a matter of minutes with Victron's free VictronConnect software (computer and MK3-USB Interface required).

As with all MultiPlus and Quattro units, the MultiPlus-II can be connected to any of Victron's monitoring and control solutions like the Cerbo GX with GX Touch 50 or GX Touch 70 accessory screen, Color Control GX (deprecated), Venus GX, CANvu GX, laptop or computer running VictronConnect through an MK3-USB Interface, Bluetooth with the optional VE.Bus Smart Dongle, and Digital Multi Control Panel.

Remote configuring and monitoring

Install a Cerbo GX or other GX device to connect to the internet.

Operational data can be stored and displayed on the VRM (Victron Remote Management) website, free of charge.

When connected to the internet, systems can be accessed remotely, and many settings can be changed.
