The Mastervolt CombiMaster range combines an intelligent 3 step battery charger providing fast and safe charging, along with a reliable true sine wave power inverter to provide AC output to operate household items. The unit can be connected up to shore power or generators for charging and the AC output will automatically switch between mains and inverter mode. The inverter/charger is built to be reliable and user friendly, with easy operation through MasterBus, CZone and NMEA 2000 communications, and with a wide range of control panels available.

The CombiMaster features the Power Assist function, which prevents main fuses or breakers being tripped in the event of a weak power supply. It also eliminates power failures and dips to maintain reliable performance. The unit is equally capable at handling heavy loads and more sensitive loads, and with a true sine wave output will not cause harm or damage to your appliances.
