A MultiPlus, plus ESS (Energy Storage System) function The MultiPlus-II is a multifunctional inverter/charger with all the functions of the MultiPlus and one additional function, namely that of an external current sensor. This extends the PowerControl and PowerAssist functions to 50 A and 100 A respectively. The MultiPlus-II is ideally suited for professional marine, yacht, vehicle and land-based, off-grid applications. The unit also has a built-in anti-islanding function and is gaining approval for an ESS application in more and more countries. Several different system configurations are possible. For more information, see the ESS Design & Configuration manual. PowerControl and PowerAssist - increasing mains or generator power A maximum mains or generator current can be set. The MultiPlus-II then takes into account other connected AC consumers and only uses the current that is "left over" to charge the battery. This prevents the generator or the mains connection from being overloaded (PowerControl function). The PowerAssist function adds a new dimension to the PowerControl principle. Load peaks often only occur for a limited period of time. In such a case, the MultiPlus-II immediately compensates for insufficient generator, shore power or mains power with energy from the battery. If the load is reduced, i.e. if consumers are switched off, the sufficient energy available can then be used to charge the batteries again. Solar power: alternating current even in the event of a grid failure The MultiPlus-II can be used with both non-grid-connected and grid-connected PV systems, as well as with other alternative energy systems. It can be used with both solar charge controllers and grid-connected inverters. Two AC outputs The main output ensures uninterrupted operation. In the event of a.
