A MultiPlus, plus ESS (Energy Storage System) functionality The MultiPlus-II is a multifunctional inverter/charger feature packed. with PowerControl and PowerAssist function. The MultiPlus-II is ideally suited for land based off-grid applications, professional marine, yachting, and mobile vehicles. It also has built-in anti-islanding functionality, and an increasingly long list of country approvals for ESS application including Lebanon. Several system configurations are possible. 

Solar energy: AC power available even during a grid failure The 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 Fronius grid-tie inverters.

PowerControl and PowerAssist: Boosting the capacity of the grid or a generator.

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 insufficient generator, shore or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery.
