48 V - Mass Combi

The Mastervolt Mass Combi combines the best of both worlds, with an advanced battery charger and silent inverter rolled into one compact device. It is ideal for most boats, from sloops to 16-metre yachts, as well as for heavy mobile applications (E-mark certified). Following the expansion of Mastervolt’s range with two 48 V models, the Mass Combi is now also available for electric propulsion.

One of the key reasons for the Mass Combi’s popularity is its versatility. The starter and service batteries are charged quickly and completely, while the inverter provides silent and clean power. When insufficient shore power is available, the Mass Combi battery provides a powerboost so that you can continue using your 230 V equipment. 

Modern technology

The design of the Mass Combi is both unique and characteristic of Mastervolt. Rather than installing heavy transformers, our lightweight, high-frequency technology offers major benefits regarding size, weight and sound (no hum!). The technology also ensures an exceptionally high efficiency with a minimal conversion loss and a low no-load consumption.
The Mass Combi meets all your requirements and more!
