For professional use: GMDSS
The Mass series is designed for the most demanding situations. To comply with SOLAS (International Convention for the Safety of Life at Sea) regulations, all Mass battery chargers are compatible with the GMDSS system. GMDSS stands for Global Maritime Distress and Safety System, and it allows users to monitor various alarm functions. GMDSS Remote Panel independent, compatible with all Mass battery chargers.
Charge Lithium-Ion Batteries
Although Lithium-ion batteries are becoming increasingly popular, the charging process may not be entirely clear. This is not a problem for Mastervolt, as Mastervolt battery chargers communicate directly with the Lithium-ion battery via the integrated MasterBus.
Compatible with MasterBus
Mass battery chargers can easily be connected to a MasterBus network with a single cable and a single connection. As if that weren't enough, you have the option of monitoring, configuring, and controlling your system centrally, locally, or remotely.
