Mastervolt Mass Battery Charger 24/25-2
The right choice for demanding conditions
Mass battery chargers 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. The Mass products are ideal for the toughest tasks and any situation that requires a reliable power supply.
GMDSS Compatible
The Mass series are designed for the most demanding situations. To help you comply with SOLAS regulation, 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.
