Victron Quattro-II 24V 3000VA 2x120 Inverter/Charger

The Victron Quattro-II 24/3000/70-50 2x120V is a premium inverter/charger designed for advanced mobile and off-grid power systems that require the flexibility of two independent AC power sources. Whether switching automatically between shore power and a generator or serving as the heart of a sophisticated Victron installation, the Quattro-II delivers reliable power management in one integrated platform.

Designed for 24V battery systems, this model combines a 3000VA pure sine wave inverter, a 70A battery charger, automatic transfer switching, and Victron's intelligent power management features into a single unit. It's an excellent choice for larger RVs, motorhomes, marine vessels, expedition vehicles, and other off-grid applications where dependable power and multiple AC inputs are essential.

Real-World Power Expectations

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 power one larger AC load while also supporting smaller loads such as lights, televisions, Starlink, routers, laptops, battery chargers, fans, and other everyday electronics. Actual performance depends on battery capacity, wiring, installation quality, appliance draw, temperature, and what else is 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 generate 240V power from the battery by itself. 240V loads are available only when the Quattro-II is supplied by an external split-phase 120/240V AC source or as part of a properly designed multi-unit Victron system.
