Description
Victron Energy MultiPlus-II 12V 3000VA 120A Pure Sine Wave Inverter/Charger 2×120V — a premium all-in-one inverter/charger engineered for backup, off-grid, and mobile power systems demanding seamless, uninterruptible performance.
Key Features
- PowerControl & PowerAssist: Intelligently manages grid or generator input limits and supplements power from the battery during peak demand on L1.
- Two AC Outputs: Main output transfers in under 18ms for uninterrupted power to critical loads, while the auxiliary output protects battery from non-essential draws.
- Split Phase & Single Phase Input: Accepts both 120/240VAC split phase and 120VAC single phase sources with full feed-through capability.
- Parallel & Three Phase Ready: Up to six units can operate in parallel, with three-unit configurations available for three-phase output setups.
- Remote Monitoring & Control: Compatible with Cerbo GX, VRM Portal, VE.Bus, and Bluetooth via optional VE.Bus Smart Dongle for full system oversight.
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%, making it a powerhouse for RV, marine, backup, and off-grid installations. A programmable relay adds flexibility for general alarm, DC under-voltage, or genset start/stop automation.
The integrated 120A battery charger features absorption, float, and storage charging modes with a built-in battery temperature sensor for optimized charge management. PowerControl ensures the charger never overloads your generator or grid by automatically adjusting charge current based on available capacity.
System configuration and monitoring are handled through VEConfigure software, with full remote access via the VRM Online Portal at no charge. The steel IP22-rated enclosure with fan-assisted cooling supports operation across an exceptional -40°C to +65°C temperature range, built for the most demanding real-world environments.
