The MultiPlus-II 2 x120V is the perfect one-box mobile solution for standard North American 50A 120/240VAC split-phase applications. Whether it is supplied from shore power or a generator, the MultiPlus-II 2x120V can accept and passthrough both lines of a 120/240V supply, with the capability to utilize the full 50A for charging and AC loads. When connecting to a single phase 120V supply, the L1 input of the MultiPlus-II 2x120V will accept incoming power for charging and passthrough, while combining the L1 and L2 outputs for single-phase 120V on each line.
The MultiPlus switches to inverter operation when no AC source is available. The inverter output is also 120V single phase. In inverter mode, the MultiPlus-II 2x120V internally connects both lines L1 and L2 together to provide 120VAC to loads on either output. Therefore, in all connection circumstances, both sides of a distribution panel will be supplied with 120V. However, 240VAC is only available when the MultiPlus is supplied by a split phase 120/240VAC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.
The MultiPlus-II 2x 120V has all of the expected features of our versatile inverter/charger range, including PowerControl, PowerAssist, Input Current Limit, two AC outputs, as well as parallel and 3ph configuration for larger capacity VE.Bus systems. Suitable for LiFePO4 batteries and a variety of other battery technologies.
Models:
3000VA
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.
When an AC source is available, the MultiPlus will feed through the AC to its output. The output will therefore mirror the
AC input.
The inverter/charger connects to the neutral and the preferred input line (L1). Power needed to charge the batteries will
therefore be drawn from L1.
The MultiPlus switches to inverter operation when no AC source is available. The inverter output is 120V single phase. In
invert mode, the MultiPlus connects both output lines (L1 and L2) together to provide 120VAC to loads on either line.
Any 240V loads will therefore be supplied only when the MultiPlus is supplied by a split phase AC source. This prevents
heavy loads such as water heaters or 240V 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 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. The MultiPlus 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. 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 Multis 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 VEConfigure software (computer or laptop and MK3-USB interface
needed).
Several monitoring and control options are available: Cerbo GX, Color Control GX, Venus 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.
