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.

PowerControl and PowerAssist:  Boosts the generator's capacity.  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 overloading (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 for insufficient generator, shore or grid power with power from the battery.  When the load reduces, the spare capacity is used to recharge the battery. 

Two AC Outputs:  The main output has no-break functionality.  The MultiPlus-II takes over the supply to the connected loads when shore/generator power is disconnected.  This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will 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, can be connected to this output.

Virtually unlimited power thanks to parallel (not for the 8k, 10k and 15k models) and three-phase operation:  Up to 6 Multis can operate in parallel to achieve higher power output.  For example, six 48/5000/70 units will provide 25 kW / 30 kVA output power with 420 Amp 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 minutes with VE.Configure 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 the VRM (Victron Remote Management) website free of charge.  When connected to the internet, systems can be accessed remotely, and settings can be changed.
