The Combimaster 12/3500-200 by Mastervolt is designed with the customer in mind. The CombiMaster range is all about user-friendliness and reliability. The automatic AC transfer system switches between generator or mains and inverter output, ensuring a constant power supply. The Power Assist function prevents tripping of the mains fuse in case you’re connected to a weak landline or small generator. The CombiMaster is completed with MasterBus, CZone, and NMEA 2000 compatible communication, allowing for a broad range of monitoring and system integration options.
