The Victron MultiPlus-II is a high-performance inverter/charger designed for advanced energy storage systems (ESS), off-grid installations, marine applications, and commercial power solutions. It combines a powerful pure sine wave inverter, an intelligent battery charger, and a fast automatic transfer switch in one robust unit.
Designed for both grid-connected and off-grid environments, the MultiPlus-II ensures seamless power continuity during outages by supplying critical loads without interruption. Integrated PowerControl and PowerAssist technology intelligently manage limited grid or generator power while supplementing peak demand using battery energy.
The MultiPlus-II integrates seamlessly with Victron GX devices and the VRM online portal, allowing remote monitoring, configuration, and system optimization. Its ability to operate in parallel or three-phase configurations makes it a scalable, future-ready solution for residential, commercial, and industrial energy systems.
