The Mass Combi, inverter and battery charger in one, is increasingly playing a leading role in carefully designed electrical systems. Mastervolt has integrated the most advanced technology into a compact package, allowing owners to get the most value for their money. This offers you high-quality basic support for smaller systems without requiring a great deal of space. You will not have to worry anymore about the quality of shore power in any port - things will always work with the Mass Combi!
The most vital functions in your electrical system now come within reach: battery charging, supplying 230V power, switching and the use of extended AC loads to be utilized on board, even when limited shore power is available. Power can be drawn from a shore connection, generator or charged batteries. Mastervolt's three-step Plus© charging method guarantees more battery power and a longer life span. Batteries are always fully charged and fast, even when a generator is used. And the clean 230V/50Hz power supply is perfectly reliable.
