The MultiPlus-II is a high-performance inverter/charger that combines the functions of the original MultiPlus with an external current sensor option, making it ideal for advanced Energy Storage Systems (ESS). It implements grid-interactive features like PowerControl, which prevents grid/generator overload by limiting charge current, and PowerAssist, which uses battery power to supplement insufficient grid/generator power during peak loads. It features an ultra-fast (<20ms) transfer switch for UPS functionality on its main output and a second AC output for non-essential loads. It is fully scalable, supporting parallel and three-phase operation, and serves as the core of a comprehensive Victron Energy system when paired with a GX device.
