Description

12V MultiPlus-II 120V Inverter/Charger – Smart Energy Conversion & Battery Management

The Victron MultiPlus-II 12V Inverter/Charger combines a powerful inverter, sophisticated battery charger, and seamless AC transfer switch in one compact unit. Designed for both off-grid and grid-connected systems, this multifunctional solution brings high-performance energy management to RVs, marine setups, home backup systems, and solar installations.

With support for an external current sensor, the MultiPlus-II expands PowerControl and PowerAssist capabilities up to 100A, ensuring your system intelligently prioritizes energy flow. It automatically adjusts battery charging based on available power, preventing grid or generator overloads by accounting for other connected AC loads.

When high power demand peaks momentarily, PowerAssist allows the MultiPlus-II to supplement the grid or generator with battery power. As the load decreases, the system redirects surplus power to recharge the batteries—optimizing energy use and maintaining stability.

Engineered for flexible integration, the MultiPlus-II works seamlessly with solar charge controllers and grid-tie inverters, making it a versatile core component for your advanced energy setup.
