Victron MultiPlus-II 12/3000 - 120V (UL Approved) is a versatile inverter/charger that combines the best of Victron’s MultiPlus and MultiGrid lines into a single, smart power solution. Engineered for backup power, off-grid, and Energy Storage Systems (ESS), it delivers reliable AC power, seamless automatic switching, and advanced monitoring options for total energy control.
Powerful Inverter, Smart Charger
- Inverter: 3000 VA / 2400 W continuous output at 25°C; 2200 W at 40°C; 1700 W at 65°C; peak power up to 5500 W; output: 120 VAC ±2% at 60 Hz ±0.1%
- Charger: up to 120 A charging current; AC input 90–140 VAC / 45–65 Hz; absorption 14.4 V; float 13.8 V; storage 13.2 V
- Maximum efficiency up to 93%; zero-load power as low as 3 W (in certain modes), 9–13 W depending on mode
- Continuous output ratings: 3000 VA / 2400 W (25°C); 2200 W (40°C); 1700 W (65°C); Maximum apparent feed-in power: 2500 VA
PowerControl & PowerAssist
- PowerControl prevents overloading a limited AC source (generator or shore power) by reducing battery charging when an overload would occur
- PowerAssist boosts the global supply by drawing power from the battery to maintain loads when needed
- External current transformer option (up to 32 A) enables precise external current sensing for optimized self-consumption and PowerAssist integration
Energy Storage Systems (ESS) & UPS
- ESS-ready: seamlessly pairs with MPPT solar chargers or grid-tie PV inverters to form a complete energy storage solution
- Uninterrupted Power Supply (UPS): in the event of grid failure or disconnection, the inverter automatically takes over in under 20 milliseconds for seamless operation of connected devices
Remote Monitoring & Control
Coupled with a Victron GX device (e.g., Cerbo GX), monitor and control the MultiPlus-II locally (LAN) or remotely via the free VRM app and VRM portal. Access from a phone, tablet, laptop or PC across multiple operating systems, with extensive control options—from system tweaks to auto-starting a backup generator.
