Complete Inverter and Charger Solution

The MultiPlus combines a true sine wave inverter with an advanced adaptive battery charger to provide clean AC power and optimized charging in one integrated package. This multifunctional design reduces installation complexity while delivering professional-grade performance.

PowerAssist Technology

The unique PowerAssist feature helps prevent overload conditions when using limited AC sources such as generators or shore power connections. When additional power is needed, the MultiPlus automatically supplements the available AC supply with energy from the connected battery bank.

Uninterrupted AC Power with UPS Function

The built-in UPS function provides seamless backup power when grid, generator, or shore power is disconnected. The inverter automatically takes over in less than 20 milliseconds, allowing computers, electronics, and other sensitive equipment to continue operating without interruption.

Expandable Power System

For larger energy requirements, up to six MultiPlus units can operate in parallel to increase available power output. Compatible configurations also support split-phase and three-phase operation for advanced electrical systems.

Remote Monitoring and Control

When connected with a compatible Victron GX device, the MultiPlus allows remote monitoring and system control through network connectivity. Users can view system performance, adjust settings, and manage their power system from a phone, tablet, laptop, or computer.
