Need some help?

The range of Mastervolt products allow you to design an electrical system around your needs. From the small AC Master inverters and compact IVO Smart battery chargers to the Mass Chargers and Mass Sine inverters for larger systems, and the Mass Combi inverter chargers.

  • One of the specific advantages of a Mastervolt battery charger is the temperatures at which it can operate at (up to 60°C) allowing you the flexibility to mount it in places other brands would struggle. Their sealed cases and resistance to temperature gives you the option of mounting them out the way in the engine room. For specific technical information and detail on any of the product range visit their website at
  • The Mastervolt inverter charger combi unit is very tolerant of poor input voltages and frequencies from your shore power, its output is a pure sinewave at 230vAC so you can be confident that you can run your sensitive equipment through the Mass combi no matter where you are. The inverter-charger combination from Mastervolt is one of the most cost and space effective solutions for a highly effective marine electrical system.
