The Victron Energy MultiPlus-II 48V 5000VA 4000W 120V 50/60Hz Inverter Charger (Model 48/5000/70-95 120V, MPN PMP482505300) combines a pure sine wave inverter, a 70A adaptive battery charger, and an integrated high-speed transfer switch in one reliable energy management unit. Built for off-grid, marine, RV, solar storage, and backup power systems, this 48 volt inverter charger delivers dependable 120VAC power with 50/60Hz frequency support while efficiently charging your battery bank.

48V 5000VA / 4000W Pure Sine Wave Inverter Charger

The MultiPlus-II provides 5000VA / 4000W of continuous pure sine wave power and a built-in 70A adaptive charger. With 120VAC output and 50/60Hz frequency support, it suits a wide range of residential, commercial, marine, and mobile power systems.

PowerAssist and PowerControl for Grid, Generator, and Shore Power

PowerControl prevents overloads by intelligently managing available AC input from the grid, generator, or shore connection. During high demand, PowerAssist supplements limited AC power with stored battery energy to support peak loads.

High-Speed UPS Backup Power

During outages or shore power interruptions, the MultiPlus-II switches to inverter power in less than 20 milliseconds, keeping sensitive electronics, appliances, and critical equipment running without disruption.

ESS and Dynamic ESS Ready

The MultiPlus-II supports advanced Energy Storage System applications with smart grid, solar, and battery management. External current transformer support enables self-consumption optimization, and built-in anti-islanding protection supports grid-connected installations.

Remote Monitoring and Scalable Design

Paired with a Victron GX device such as the Cerbo GX, the MultiPlus-II supports remote monitoring, system configuration, generator control, and real-time performance tracking through the Victron VRM platform. Parallel and three-phase operation let your system expand as power needs grow.
