Victron Energy MultiPlus-II 48V 5000VA 4000W 120V Pure Sine Wave Inverter Charger, 70A Battery Charger, 95A Transfer Switch, VE.Bus, ESS Compatible

The Victron Energy MultiPlus-II 48V 5000VA 4000W 120V Inverter Charger (MPN PMP482505110) combines a pure sine wave inverter, a 70A adaptive battery charger, and a 95A automatic transfer switch in one powerful energy management unit. Built for off-grid solar, home backup, RV, marine, and energy storage systems, this 48 volt inverter charger delivers reliable 120VAC power while intelligently managing battery charging and shore power or generator input.

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

The MultiPlus-II provides 5000VA / 4000W of continuous pure sine wave power, 9000W peak capacity, and up to 96% efficiency with fan-assisted cooling. Its 70A adaptive charger supports lithium, AGM, gel, and lead-acid battery banks, and dual AC outputs let you separate critical and non-critical loads.

PowerAssist and PowerControl for Generators and Shore Power

PowerControl prevents overloads on limited shore power or generator sources. During peak demand, PowerAssist supplements the AC input with battery power, and once demand drops, surplus power is redirected to recharge the battery bank.

95A Transfer Switch with UPS Backup

The integrated 95A transfer switch provides seamless power transfer in less than 20 milliseconds during utility or generator outages, keeping computers, networking equipment, sensitive electronics, and essential appliances running without interruption.

Solar, ESS, and Expandable System Support

The MultiPlus-II works with Victron MPPT solar charge controllers, grid-tie inverters, lithium batteries, and Victron Energy Storage Systems (ESS). Up to six units can operate in parallel, and split-phase 240V and three-phase configurations are supported as your power needs grow.

Remote Monitoring and VE.Bus Integration

VE.Bus communication enables advanced system integration, and when paired with a Victron GX device, the MultiPlus-II supports remote monitoring and control through the Victron VRM platform.
