Absolute reliability in the most harsh conditions


In commercial shipping, vessels such as tugs, inland vessels, supply vessels or transport vessels serve as places of work. Absolute reliability is of paramount importance and Mastervolt has developed specific products for the commercial sector that reflect this reality. Our Mass products offer premium functionality round the clock at high temperatures and in polluted environments. Featuring the best possible shock and vibration attenuation, Mass products meet the highest standards in the industry.

Commercial shipping requires products with a long lifespan, backed up by fast service, anywhere in the world. Because Mastervolt has been specialising in these aspects for the past 25 years, we maintain excellent relations with countless professional shipbuilders.

Whether you are off on a worldwide journey or a few days on the road, being independent from grid connected power requires alternative energy sources. Ultimately, an energy source that generates its own power will be required. Mastervolt offers a wide range of power solutions that generate energy from (solar) charge regulators to high-output alternators.
