The Victron Quattro-II is the compact, lighter generation of the Quattro: an inverter, charger and dual-input automatic transfer switch in one. It takes shore power or grid on one input and a generator on the other, picks the right source automatically, and switches to battery power in milliseconds if both drop out. It suits boats, off-grid homes and backup systems where you want genset plus grid or shore without extra switchgear.
