As the name suggests, the MultiPlus is a combination of an inverter and a charger. This elegant solution offers numerous features such as those of a true sine wave inverter, an adaptive charging function, hybrid PowerAssist technology, and multiple options for system integration. The MultiPlus prevents a limited AC source, such as a generator or shore power connection, from being overloaded. First, the battery charging process is automatically reduced to protect against overload. Next, the power from a generator or shore power supply is boosted with energy from the battery.
