Designed with the customer in mind and using the latest technology, the CombiMaster range is all about user-friendliness and reliability. But don’t let that friendly appearance misguide you: the powerful CombiMaster range drives even the heaviest and most sensitive loads with ease!
With the CombiMaster, power dips and failures belong to the past. The automatic AC transfer system switches between generator or mains and inverter output, ensuring a constant power supply. Its Power Assist function prevents tripping of the mains fuse in case you’re connected to a weak land line or small generator.
The CombiMaster range delivers unmatched performance and value for money. As you would expect from Mastervolt, the CombiMaster is completed with MasterBus, CZone and NMEA 2000 compatible communication, allowing for a broad range of monitoring and system integration options.
The CombiMaster 3500/4500/5000 functionality goes beyond stand-alone operation, the design also allows parallel and split phase configurations for larger applications up to 35 kW.
