BigBattery | Victron MultiPlus-II 24/3000/70-50 (UL 458) | INV016

The MultiPlus-II is a versatile inverter/charger that builds upon the proven capabilities of the MultiPlus series, enhanced with support for an external current sensor. This upgrade extends PowerControl and PowerAssist functionality up to 100A, delivering greater flexibility and performance in demanding power environments.

A maximum allowable current from the grid or generator can be configured. The MultiPlus-II intelligently accounts for other connected AC loads and allocates any remaining capacity to battery charging, effectively preventing grid or generator overload through its PowerControl feature.

PowerAssist further expands this capability by supplementing limited shore, generator, or grid power with battery power during short-term peak demands. Once the load decreases, available excess power is automatically redirected to recharge the batteries, ensuring optimal system efficiency.

Designed for both off-grid and grid-connected applications, the MultiPlus-II integrates seamlessly with PV systems and other alternative energy setups. It is fully compatible with solar charge controllers as well as grid-tie inverters, making it suitable for a wide range of residential and commercial energy solutions.
