The Victron Energy MultiPlus-II inverter is a pure sine wave device that combines an inverter, battery charger, and automatic transfer switch. It is designed for 24 V battery systems and use in energy storage systems (ESS). The UPS function automatically activates the inverter in less than 20 ms in the event of an unstable or interrupted grid supply.

The charger has a charging current of 120 A and uses the Adaptive Charge algorithm, which adjusts charging according to the battery’s condition. The PowerControl and PowerAssist functions manage the external power supply and supplement it with power from the battery when needed. The device connects to GX devices via the VE.Bus port for monitoring and configuration.
