Mastervolt CombiMaster Pure Sine Wave Marine Inverter/Charger 3000W 24VDC to 230VAC

Unmatched performance and user-friendly design

Designed using the latest technology, the Mastervolt CombiMaster Inverter/Charger 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 landline or small generator.

The CombiMaster delivers unmatched performance and value for money. As you would expect from Mastervolt, it's completed with MasterBus, CZone and NMEA 2000 compatible communication, allowing for a broad range of monitoring and system integration options.

Remote Control and Monitoring Options:

• MasterBus compatible via SmartRemote or EasyView 5 display
• CZone / NMEA 2000 compatible via Touch 5 or Touch 10 display
• NMEA 2000 compatible via 3rd party multifunctional display
