webapplications mg Applications:

The LFP series is designed for use in a large range of applications such as mobile, marine and off-grid. For example to power electric motors for hydraulic power packs or electric-hybrid propulsion systems.

Easy Installation:

Combining the LFP series batteries with the MG Master LV or MG Master HV creates a compact system with reduced wiring and external components. The MG Master LV combines battery monitoring and control, DC distribution, fuse box and shunt in one device which saves installation time and space.

websafety mg Safety:

Each battery module comes with an integrated battery management system (BMS). This is an intelligent electronic module (slave BMS), that measures all cell voltages and temperatures to control balancing on both battery cell and module level. The battery modules communicate by a galvanic isolated CAN-Bus with the MG Master LV or HV (master BMS), which collects and monitors the status of all battery modules. If the measured values from a battery module exceed the limit, the MG Master will automatically take action to protect the connected battery modules.

Battery Management Controllers:

Protecting, monitoring and controlling a battery system is very important to create a safe, reliable and easy-to-use system. The MG Master LV or HV is the safety and control unit of the battery system. It protects the connected battery modules against over-charging, over-discharging, over-temperature, under-temperature and controls the balancing of the battery cells. Besides a safety funtion, the MG Master LV or HV monitors and tracks other important parameters to give insight in the battery status and energy consumption. MG’s battery system CAN-bus protocol can be used to communicate with other equipment and multi functional display’s (MFD’s) by NMEA2000 and web interface. The MG Master LV and HV ensure an easy and proper installation. Thanks to the built-in safety components a reliable installation is guaranteed.

webscalability mg Energy Storage Systems:

System flexibility is one of the main key features of all MG products. Combining LFP series batteries together with one of the Master BMSs creates a powerful system for a complete range of applications. Redundant systems can be made by connecting multiple Master BMSs in parallel to increase system reliability and capacity.
