CombiMaster 24/3000-70 (120 V) - The CombiMaster inverter/charger provides pure sine wave inverter power and multicharge battery charging, and its intelligent design communicates seamlessly with NMEA 2000, CZone and MasterBus networks.
The CombiMaster range is designed with the customer in mind and uses the most modern technology, and it is also reliable and easy to use. But don't let its good looks deceive you: the powerful CombiMaster range handles the heaviest and most delicate loads with ease!
With CombiMaster, voltage drops and breakdowns are a thing of the past. The automatic AC transfer system switches between generator or mains output and inverter output, ensuring a constant power supply. Its Power Assist function prevents the mains fuse from blowing if the user is connected to a weak shore power line or a small generator.
The CombiMaster range offers unmatched performance and value for money. As you would expect from Mastervolt, CombiMaster comes complete with communication compatible with MasterBus, CZone and NMEA 2000, offering a wide range of monitoring and system integration options.
