Multiplus-II 2×120 Inverter/Charger 120V

Description

The Victron MultiPlus-II 2×120 is an advanced inverter/charger engineered specifically for North American 50A split-phase RV electrical systems. Whether you’re plugged into campground shore power, running a generator, or camping off-grid, it intelligently manages AC power and battery charging to keep your RV running smoothly.

Unlike standard inverter/chargers, the MultiPlus-II 2×120 is designed to work seamlessly with the two-leg electrical service found in 50A RVs, providing reliable power management without compromising the functionality of your onboard electrical system.

Designed for 50A Split-Phase RV Service

Most 50A RVs receive power through two independent 120V legs (L1 & L2). The MultiPlus-II 2×120 is purpose-built to operate with this configuration.

When connected to 50A shore power or a generator, it:

• Passes through both incoming 120V legs to your RV’s electrical panel.
• Charges your battery bank while powering your appliances.
• Automatically transfers between available power sources without interruption.

Keeps Both Sides of Your RV Powered

One of the MultiPlus-II 2×120’s standout features is its ability to operate when connected to 30A or even a standard 15A household outlet.

Instead of powering only one side of your RV’s breaker panel, it automatically bridges both 120V output legs so your RV’s circuits remain energized from a single 120V source. This means more outlets and appliances remain available even when you’re connected to limited shore power.

Automatic Inverter Power

When shore power or generator power is unavailable, the MultiPlus-II instantly switches to inverter mode.

It supplies clean, pure sine wave AC power from your battery bank to both 120V legs of your RV, allowing essential appliances and electronics to continue operating with virtually uninterrupted power.

PowerAssist Technology

Campground power isn’t always reliable. Victron’s exclusive PowerAssist feature helps prevent overloaded breakers by supplementing shore or generator power with energy from your batteries whenever demand temporarily exceeds the available supply.

When demand decreases, the unit automatically resumes charging the batteries.
