Victron Energy MultiPlus-II 12V 3000VA 2400W Pure Sine Wave Inverter Charger, 120A Battery Charger, 2x120V, 50A, VE.Bus, ESS Compatible

The Victron Energy MultiPlus-II 12V 3000VA 2400W Inverter Charger (Model 12/3000 120-50 2x120V, MPN PMP122305100) is a high-performance pure sine wave inverter charger built for marine, RV, off-grid solar, residential backup, and commercial energy storage systems. It combines a 3000VA inverter, a 120A adaptive battery charger, a 50A transfer switch, and dual 120V outputs in one compact unit, delivering dependable AC power while maximizing battery performance and system efficiency.

12V Pure Sine Wave Inverter Charger with Dual 120V Output

The MultiPlus-II provides 3000VA / 2400W of continuous pure sine wave power with 5500W peak capacity and up to 93% efficiency. Dual 120VAC outputs, built-in anti-islanding protection, and a 120A adaptive charger make it a versatile core for both mobile and stationary power systems.

PowerAssist and PowerControl for Generators and Shore Power

PowerAssist supplements limited shore power or generator capacity with battery power during periods of high demand. PowerControl automatically manages charging current to prevent overloading AC sources, keeping RV, marine, and off-grid systems running reliably.

Built-In UPS Backup Power

When shore, grid, or generator input is interrupted, the MultiPlus-II transfers connected loads to inverter power in less than 20 milliseconds. Sensitive electronics, networking equipment, and essential appliances continue operating without interruption.

Optimized for Victron Energy Storage Systems (ESS)

The MultiPlus-II serves as the central inverter charger in Victron ESS installations, supporting solar, battery storage, backup power, and hybrid energy systems. It integrates with MPPT solar charge controllers and grid-tie PV inverters to maximize self-consumption and energy independence.

Remote Monitoring and System Control

Paired with a compatible Victron GX device such as the Cerbo GX, the MultiPlus-II supports remote monitoring and management through the Victron Remote Management (VRM) platform. View battery status, inverter performance, charging data, and system diagnostics from anywhere.
