Description
Victron Energy MultiPlus-II 12/3000/120-50 120V Pure Sine Wave Inverter/Charger — a professional-grade multifunctional inverter/charger with integrated Energy Storage System functionality for off-grid, marine, mobile, and grid-parallel applications.
Key Features
- PowerControl & PowerAssist: Intelligently prevents generator or grid overload and supplements power from the battery during peak demand periods.
- Two AC Outputs: Main output transfers in under 20ms for uninterrupted critical load protection, while the auxiliary output disconnects when AC input is unavailable.
- ESS Compatibility: Fully compatible with solar charge controllers and grid-tie inverters for seamless grid-parallel and off-grid PV system integration.
- Parallel & Three Phase Ready: Up to six units operate in parallel, with split-phase and three-phase configurations supported for scalable power expansion.
- Remote Monitoring & Control: Compatible with Cerbo GX, Ekrano GX, VRM Portal, VE.Bus, and Bluetooth via optional VE.Bus Smart Dongle.
The MultiPlus-II 12/3000/120-50 delivers 3000VA and 2400W of continuous pure sine wave output at 25°C with a peak efficiency of 93% and 5500W peak power capability. A programmable relay provides flexible automation for general alarm, DC under-voltage, or genset start/stop functions.
The integrated 120A battery charger features absorption, float, and storage charging modes with a built-in battery temperature sensor ensuring optimized, battery-safe charging at all times. PowerControl continuously monitors available AC input and automatically adjusts charge current to prevent generator or grid overload.
Full system configuration is handled via VEConfigure software with remote access through the free VRM Online Portal. The steel IP22-rated enclosure with fan-assisted cooling supports a wide -40°C to +60°C operating range, and is UL458 listed for demanding professional installations.
