Holiday Sale Quattro 48/3000/35-50/50 120V VE.Bus Inverter/Charger

Victron Quattro 48/3000/35-50/50 120V inverter/charger for 48V battery systems, featuring 3000 VA inverter output, 35A charging, two AC inputs, integrated transfer switching, PowerControl, PowerAssist, and lithium-ion battery compatibility for off-grid, backup, marine, RV, and alternative energy systems.

The Victron Quattro 48/3000/35-50/50 120V is a 48V inverter/charger designed to combine battery-based AC power, charging, and automatic source switching in one system. It can connect to two independent AC sources, such as grid and generator power or two generators, and automatically connects to the active source.

The main AC output provides no-break functionality, allowing the Quattro to take over connected loads when grid, shore, or generator power is disconnected. Transfer occurs in less than 20 milliseconds, helping computers and other sensitive electronics continue operating without interruption. A second AC output is also available and is live only when AC input power is present, making it useful for loads that should not discharge the battery.

PowerControl helps manage limited generator, shore, or grid capacity by limiting AC input current and using only available spare power for charging. PowerAssist can supplement limited AC source power with battery power during short peak-load periods, then recharge the battery when load demand decreases.
