Collection: Charger/Inverter Combos

A combined inverter and charger handles two jobs in one box: converting battery bank DC power into AC for onboard appliances, and charging those batteries from shore power or a generator. The units here, from Mastervolt, Samlex America, and Xantrex, range from 1200 to 4000 watts in both 12V and 24V configurations to match your existing electrical system. One key choice is sine wave type: pure sine suits sensitive electronics and variable speed motors, while modified sine covers simpler loads at a lower price.

Before buying, confirm your battery bank voltage, then size the inverter wattage to your peak AC load and the charger amperage to your battery capacity. Mastervolt's PowerCombi and CombiMaster lines are built for heavier-duty marine use, with charger outputs reaching 160 amps on 12V models. Xantrex Freedom units suit cruisers who want automatic transfer switching between shore power and inverter. Samlex covers 1500 to 4000 watts for installs needing that output range at a lower price. Measure available space before ordering, since ventilation clearance and cable runs affect where these units mount.
