Victron Quattro-II 2×120 Inverter/Charger 120V

Description

The Victron Quattro-II 2×120 is a premium inverter/charger engineered specifically for North American 50A split-phase RV electrical systems. Combining a pure sine wave inverter, adaptive battery charger, and automatic transfer switching in one unit, it provides dependable power whether you’re connected to shore power, running a generator, or living off-grid.

Its biggest advantage is dual AC inputs, allowing you to connect both shore power and a generator at the same time. The Quattro-II automatically selects the available power source, eliminating the need for an external transfer switch and ensuring seamless operation wherever your travels take you.

Designed for 50A Split-Phase RV Service

Modern 50A RVs use two independent 120V legs (L1 & L2) to distribute power throughout the coach. The Quattro-II 2×120 is purpose-built for this configuration, delivering full pass-through power while simultaneously charging your battery bank whenever an external AC source is available.

Works on 50A, 30A, or 15A Hookups

Whether you’re plugged into a full 50A campground pedestal, a 30A hookup, or even a standard 15A household outlet, the Quattro-II automatically adapts to the available power source.

When connected to a single 120V supply, it intelligently powers both sides of your RV’s electrical panel, allowing more outlets and appliances to remain operational without manual switching.

Automatic Inverter Operation

If shore or generator power becomes unavailable, the Quattro-II instantly switches to inverter mode, supplying clean pure sine wave power from your battery bank with virtually uninterrupted operation.

To help protect your battery system, 240V loads are only energized when connected to a true split-phase AC source.

Intelligent Energy Management

Victron’s advanced power management technologies maximize every available power source.

PowerAssist automatically supplements limited shore or generator power with battery energy whenever demand temporarily exceeds the available AC supply.

PowerControl lets you set a maximum shore power input limit, helping prevent overloaded campground breakers while optimizing battery charging.
