Victron Quattro 24/5000/120-100/100 120V VE.Bus (UL 458)

The Victron Quattro 24/5000/120-100/100 is a 24V, 5000VA inverter/charger for 120V North American systems, listed to UL 458. What sets the Quattro apart from the MultiPlus is its second AC input: connect two independent sources, such as shore power and a generator or grid and a generator, and the built-in transfer switch automatically connects to whichever one is live. Each input passes up to 100A. PowerControl sets a current limit per input so the charger never overloads a small generator, and PowerAssist tops up a weak source with battery power during high-load moments. On loss of all AC sources the main output switches to inverter power in under 20 milliseconds. A second AC output is live only when AC input is present, for loads like a water heater that shouldn't run off the battery.

Going to 120/240V? Two Quattros can be configured for split-phase output, and up to four sets of three can be paralleled for very large systems. Other 120V Quattros: the Quattro 12/5000/220-100/100 for 12V banks and the Quattro 48/5000/70-100/100 for 48V.
