Product Summary:

The Victron MultiPlus-II 12/3000/120-50 (UL 458) is a versatile 12V inverter/charger designed for mobile, off-grid, and hybrid energy systems. Delivering 3,000 VA of inverter power with a 120 A battery charger, it features an external current sensor that extends PowerControl and PowerAssist up to 100 A, allowing intelligent management of generator, shore, or grid input without overload.

 

With PowerControl, the MultiPlus-II limits incoming AC current while optimizing battery charging. PowerAssist supplements peak loads by drawing from the battery when external power is insufficient, then automatically recharges the battery as demand decreases. Compatible with solar charge controllers and grid-tie inverters, and certified to UL 458, the Victron MultiPlus-II 12/3000 is ideal for RVs, marine systems, backup power, and advanced off-grid installations requiring reliable, clean AC power.
