Victron Energy MultiPlus-II 12V 3000VA 2x120V Inverter Charger 50A UL Approved

Victron Energy MultiPlus-II 12V 3000VA 2x120V Inverter Charger With PowerAssist & UPS Backup

The Victron Energy MultiPlus-II 12/3000 2x120V UL Approved Inverter Charger combines a powerful pure sine wave inverter, advanced battery charger, and intelligent energy management system into one compact solution. Designed for marine, RV, off-grid, backup power, and energy storage applications, the MultiPlus-II delivers reliable AC power with advanced features including PowerControl, PowerAssist, UPS functionality, and remote system monitoring.

Featuring a dual 120V AC output design, the MultiPlus-II is optimized for North American power systems requiring flexible AC distribution. It combines the trusted MultiPlus platform with MultiGrid technology, including built-in anti-islanding protection and advanced self-consumption optimization through external current sensing.

PowerAssist & PowerControl Technology

The integrated PowerAssist technology prevents limited AC sources such as generators or shore power connections from being overloaded. When available AC power is insufficient, the MultiPlus-II automatically supplements power from the connected battery bank to handle temporary peak loads.

With PowerControl, users can set a maximum input current limit. The MultiPlus-II intelligently manages available power by reducing battery charging when necessary to prevent overload conditions.

2x120V AC Output for Flexible Power Systems

The 2x120V configuration provides enhanced compatibility with North American electrical systems, making it ideal for RVs, marine applications, and off-grid installations requiring dependable 120V power distribution.

Uninterrupted UPS Backup Power

When shore power, grid power, or generator input is interrupted, the MultiPlus-II automatically switches to inverter operation to maintain power to connected equipment. With a transfer time of less than 20 milliseconds, sensitive electronics such as computers and communication equipment continue operating without interruption.

Compatible With Victron ESS Energy Storage Systems

The MultiPlus-II serves as a core component in Victron Energy Storage Systems (ESS), allowing integration with solar MPPT charge controllers and grid-connected solar inverters. It provides flexible energy management for backup power, solar storage, and off-grid applications.

Remote Monitoring & Control

When paired with a Victron GX device such as the Cerbo GX, users can monitor and control their complete power system locally or remotely. Access system information, adjust settings, monitor battery status, and manage connected equipment through a phone, tablet, laptop, or computer.
