Victron Energy MultiPlus-II 12V 3000VA 2400W 120V Pure Sine Wave Inverter Charger, 120A Battery Charger, 50A Transfer Switch, PMP122305122

The Victron Energy MultiPlus-II 12V 3000VA 2400W 120V Inverter Charger (Model 12/3000 120V, MPN PMP122305122) combines a pure sine wave inverter, a 120A battery charger, and a 50A transfer switch in one compact unit. Built for off-grid, marine, RV, backup power, and energy storage applications, this 12 volt inverter charger pairs the proven MultiPlus and MultiGrid platforms to deliver reliable 120VAC power, intelligent battery charging, and seamless system integration.

12V 3000VA / 2400W Pure Sine Wave Inverter Charger

The MultiPlus-II provides 3000VA / 2400W of continuous pure sine wave power with 5500W peak capacity and up to 93% efficiency. Its 120A integrated charger and built-in battery temperature sensor deliver optimized charging for lithium and other battery systems.

PowerAssist and PowerControl for Generators, Shore, and Grid Power

PowerControl automatically adjusts battery charging to prevent overloading generators, shore power, or grid connections. When additional power is needed, PowerAssist supplements the available AC input with battery energy.

Built-In UPS Backup Power

During a grid, generator, or shore power failure, the MultiPlus-II automatically switches to inverter mode with an ultra-fast transfer time, keeping computers, sensitive electronics, and equipment running without interruption.

Energy Storage System (ESS) Compatible

The MultiPlus-II is a core component of Victron energy storage systems, working with Victron solar charge controllers, lithium battery systems, and grid-connected solar applications for greater energy independence.

Parallel, Split-Phase, and Three-Phase Operation

Multiple units can be connected for increased power output and configured for parallel, split-phase, or three-phase operation, making the MultiPlus-II suitable for residential backup, commercial installations, and large off-grid systems.

Remote Monitoring and Control

Paired with a Victron GX device, the MultiPlus-II can be monitored and controlled locally or remotely. Adjust settings, track battery performance, view system status, and manage connected equipment from a smartphone, tablet, or computer. A programmable relay supports alarms and generator control.
