What Is a Victron Inverter/Charger?
An inverter/charger is an all-in-one power device that both converts DC battery power into AC household power (inverter) and charges your batteries from AC shore power or a generator (charger). In simple terms, it lets you run your regular appliances off your vehicle’s battery bank and then refill those batteries whenever you have access to grid or generator power—automatically and seamlessly.
