Tripp Lite's RV750ULHW Inverter/Charger is the quiet alternative to gas generators-with no fumes, fuel or noise to deal with! It provides equipment with utility- or generator-supplied AC electricity filtered through premium ISOBAR surge protection. This DC-to-AC inverter with automatic line-to-battery transfer and integrated charging system serves as an extended run UPS, a standalone power source or an automotive inverter. Supplies up to 750 watts of continuous 120V AC power from any 12V DC battery or automotive DC source. OverPower inverter output feature temporarily provides up to 150% of the continuous output for 1-60 minutes and DoubleBoost TM inverter output feature delivers up to 200% of the continuous output for up to 10 seconds. When hardwire AC input is energized, commercial power passes through to connected equipment and the battery set is recharged via 3 stage, selectable 11/45 amp charging system.
