Couldn't load pickup availability
The Victron MultiPlus-II 12/3000/120-50 120V is the go-to 12V inverter/charger for RVs, vans, boats, and off-grid cabins — 3000VA of pure sine wave output, a powerful 120A multi-stage battery charger, and a 50A transfer switch in one unit. It combines the features of the MultiPlus and MultiGrid lines, with an external current transformer option for PowerControl/PowerAssist with external current sensing (max. 32A) and built-in anti-islanding.
Key features
- PowerAssist — prevents overload of a limited AC source such as a generator or shore power connection by adding inverter power when loads peak.
- Uninterrupted power — if grid, shore, or generator power fails, the inverter takes over the connected loads within 20 milliseconds.
- Scalable — up to 6 units in parallel for higher output; three units can be configured for three-phase output.
- VE.Bus — integrates with Cerbo GX for full remote monitoring via Victron VRM.
- 120A adaptive charger — charges lithium (LiFePO4), AGM, gel, and flooded banks with configurable charge profiles via VictronConnect.
