Victron MultiPlus-II 24V 3000VA 2x120 Inverter/Charger

Product Summary

The Victron MultiPlus-II 24/3000/70-50 2x120V is a 24V inverter/charger designed for professional-grade mobile and off-grid power systems. It combines a 3000VA inverter, 70A battery charger, and 50A transfer switch in one Victron platform for RV, marine, overland, mobile workspace, and off-grid installations.

This 2x120V model is especially useful in many 50A RV-style AC systems because, when operating from battery power, it provides 120V single-phase output to loads on both L1 and L2 output legs. It does not create 240V power from the battery by itself; 240V loads require a proper split-phase 120/240V AC source or a correctly designed multi-unit system.

As part of a complete Victron-based mobile power ecosystem, the MultiPlus-II can work with compatible monitoring, charging, battery, and control components to help customers build a more capable and visible power system for life on the move.

Real-World Power Expectations

As a single unit, this inverter/charger is best understood as a practical “one major appliance plus everyday background loads” power solution. In a properly sized system, it may typically support one larger AC load at a time along with smaller loads such as lights, fans, device chargers, TVs, routers, Starlink, computers, or a CPAP machine. Actual performance depends on battery capacity, wiring, installation, appliance draw, configuration, temperature, and what else is running at the same time.

For larger systems, Victron inverter/chargers can be used in expanded configurations when properly designed and configured. In those systems, total capability depends on the number of units, battery bank, AC layout, charging sources, and overall system design.
