Flexibility and scalability:

System flexibility is one of the key features of MG E-Rack. The combination of the modular rack and the HE batteries creates a powerful system for a wide range of applications with system voltages of 25.2V up to 465V and capacities of 7.5kWh up to several MWh

Redundancy:
 

Reliability of energy storage becomes more important as it is used in off-grid and backup power systems. E-racks can be set up to provide redundancy. In that case each E-Rack contains a master battery management system which is digitally combined to control chargers and inverters. Should one E-Rack fail, it goes to fail-safe and the system will keep operating with the other E-Racks.


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.
 

Remote and local monitoring:

The MG Energy monitor can optionally be added to the rack. This enables local and remote monitoring of the battery system. The integrated WiFi in the MG Energy monitor connects to the MG Energy Portal to view the status of the system and give insight in the energy flows.
