The Victron Quattro-II 2x120V is built for large RVs and off-grid systems that need two AC inputs — connect both shore power and a generator, and the Quattro automatically switches to whichever source is active. Designed for North American 50A 120/240V split-phase service, it combines high-output inverting, powerful charging, PowerAssist, and parallel/3-phase scalability.
Quattro or MultiPlus? Our Victron inverter buyer's guide breaks down the choice. Browse all Victron inverter/chargers.
Similar to the MultiPlus-II 2x120V, the Quattro-II 2x120V is a combined inverter and charger specifically designed for standard North American 50A 120/240VAC split-phase applications. Additionally, it can accept two AC inputs and automatically connects to the active source.
Whether supplied from shore power or a generator, the Quattro-II 2x120V can accept and pass through both lines of a 120/240V supply, using the full 50A for charging and AC loads. When connected to a single-phase 120V supply, the L1 input accepts incoming power for charging and passthrough while combining the L1 and L2 outputs for single-phase 120V on each line.
The Quattro switches to inverter operation when no AC sources are available; the inverter output is 120V single-phase. 240VAC is only available when supplied by a split-phase 120/240VAC source, which prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.
The Quattro-II 2x120V includes all the expected features of our inverter/charger range — PowerControl, PowerAssist, Input Current Limit, two AC outputs, plus parallel and 3-phase configuration. Suitable for LiFePO4 and a variety of other battery technologies.
