The Victron 24V Quattro-II 3kVA 2X120V comes with a built-in PowerAssist that can help out when the AC input fails by drawing on the battery. Or if needed, completely switch off the grid and run solely on battery power. In an on-grid scenario, the ESS mode allows for grid-sellback functionality. With a two-pole transfer switch, the Quattro-II 2x120V can have two AC inputs that work independently of each other.

The 24V Quattro-II offers clean uninterrupted power to keep your devices running. Being able to be used in a UPS function with less than 20 millisecond transfer time, all that is needed is to turn the setting on. The Quattro-II has a low idle draw of 13W and a high efficiency of 94%, this makes it good for both mobile and residential systems.
