Victron Quattro-II 12V 3000VA 2x120 Inverter/Charger
The Victron Quattro-II 12/3000/120-50 2x120V is a premium inverter/charger designed for advanced mobile and off-grid power systems that need the flexibility of two independent AC inputs. Whether switching automatically between shore power and a generator or managing power in a larger Victron ecosystem, the Quattro-II helps keep your electrical system running seamlessly.
Built around Victron's proven inverter and charging technology, this model combines a 3000VA pure sine wave inverter, a high-output 120A battery charger, automatic transfer switching, and intelligent power management into a single platform. It is an excellent choice for larger RVs, marine applications, overland vehicles, and other mobile installations where multiple AC power sources are available.
As a single unit, the Quattro-II 3000VA is best understood as a practical "one major appliance plus everyday background loads" power solution. In a properly designed system, it can typically support one larger AC load while also powering smaller loads such as lights, televisions, routers, Starlink, laptops, battery chargers, fans, and similar everyday equipment. Actual performance depends on battery capacity, wiring, installation quality, appliance draw, system configuration, temperature, and other loads operating at the same time.
When operating from battery power, this 2x120V model supplies 120V AC on both L1 and L2 output legs. It does not create 240V power from the battery by itself. 240V loads are only supported when the unit is supplied by an external split-phase 120/240V AC source or as part of a properly designed multi-unit Victron system.
