Victron Quattro 48/5000/70-100/100 120V VE.Bus

The Victron Quattro adds a second AC input with a fully integrated transfer switch to the standard MultiPlus feature set — ideal for systems that need to automatically switch between two AC sources, such as shore power and a generator, or grid and generator backup. PowerAssist boosts a limited AC source with battery power during high loads, and if both AC sources fail, the inverter takes over instantly to keep connected loads running.
