Victron MultiPlus II 8000VA

The MultiPlus II inverter is a multi-functional inverter/charger with all the features of the MultiPlus, plus an external current sensor option that 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 is NERSA-approved.

Thanks to the programming features of this inverter, several system configurations are possible. For example, 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 for insufficient generator, shore or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery.
