Victron Energy MultiPlus-II 48/3000 35-50 120V One Size. PowerControl and PowerAssist - Boosting the Capacity of the Grid or a GeneratorA 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 FailureThe 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 OutputsThe 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.
