For the toughest tasks
Mass battery chargers, sine wave inverters and DC-DC converters are designed for the toughest conditions for professional, semi-professional and recreational purposes. Even under the most extreme conditions the products from the Mass series operate faultlessly, giving you round-the-clock output when necessary. The sustainability and technologies that underpin the Mass concept have long been proven in practice. With an MTBF of 280,000 hours at full capacity and 24/7 use, the Mass products are ideal for the toughest tasks and any situation that requires a reliable power supply. You can always rely on their proven and technically advanced components.
Making the best even better
The reliability and long lifespan of Mastervolt’s battery chargers, sine wave inverters and DC-DC converters have been established beyond doubt over the past decade. While the Mass products have evolved with the latest technological developments, the dimensions and connections have remained the same. As a result it is exceptionally easy to replace one unit with another with only negligible downtime.
Mastervolt Green by Heart
As part of our constant search for eco-friendly and long-lasting solutions, Mastervolt has developed the Green by Heart programme. Its impact on the Mass battery chargers, Mass Sine inverters and Mac & Magic DC-DC converters include:
An exceptionally effective use of the consumed input current (cos phi) > 0.98!
Faster charging of batteries, even when the input current is limited.
Use of top quality components with a long lifespan.
Savings in weight and space.
Fewer installation materials.
