The MultiPlus-II is a powerful all-in-one inverter and charger, building upon the trusted performance of the original MultiPlus with added features like an external current sensor option—extending PowerControl and PowerAssist capabilities up to 100A.
With the ability to set a maximum generator or grid input current, the MultiPlus-II intelligently manages power by prioritizing other AC loads and utilizing surplus power for battery charging—preventing system overloads through its advanced PowerControl function.
PowerAssist further enhances performance by drawing on battery reserves during short periods of high demand, supplementing grid, shore, or generator power. Once the demand drops, it automatically recharges the battery using the available spare energy.
Ideal for both off-grid and grid-connected systems, the MultiPlus-II integrates seamlessly with solar charge controllers and grid-tie inverters, offering a flexible and reliable solution for modern energy needs.
