Dual AC input inverter/charger with automatic source transfer, parallel capability, and PowerAssist.
The Victron Quattro is a combined inverter and charger with two independent AC inputs, automatically connecting to whichever source is active. This makes it ideal for systems with both shore/grid power and a generator, eliminating the need for an external transfer switch. It delivers 5,000VA of true sine wave output with up to 10,000W peak power on the 48V model.
PowerAssist technology supplements limited AC sources by adding inverter power during peak loads. The adaptive charge algorithm supports lithium, AGM, gel, and flooded battery chemistries. Full VE.Bus integration enables parallel and three-phase configurations managed through a Cerbo GX or other GX device.
Used in Alchemy industrial power systems where both grid/shore and generator inputs need automatic failover and load management.
