GMDSS Compatible

The Mass series are designed for the most demanding situations. To help you comply with SOLAS regulations, all Mass battery chargers are GMDSS compatible. GMDSS stands for Global Maritime Distress and Safety System and allows users to monitor various alarm functions. GMDSS versions of the Mass 24/25 DNV, Mass 24/50, Mass 24/75, Mass 24/100, and Mass 24/100-3ph are available.

A separate remote panel is available, which is compatible with all Mass battery chargers.

A single front display with GMDSS remote panel is available for:     

• Mass 24/25-2 DNV


• Mass 24/50-2


• Mass 24/75, Mass 24/100, Mass 24/100-3ph

Charging Lithium Ion batteries

Although Lithium Ion batteries are increasingly popular, there can be a lack of clarity when it comes to the charging process. This is not a problem with Mastervolt as the Mastervolt battery chargers communicate directly with the Lithium Ion battery via the integrated MasterBus (or have been adapted to the required charging voltages).

MasterBus compatible

Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. You can also choose central, local, or remote monitoring, configuration, and control of your system.
