MG Master LV — BMS for low-voltage battery systems 12–96 V
Country: Netherlands · Model: Master LV
The master BMS Master LV manages MG low-voltage batteries of 12–96 V and switches a current of up to 1000 A with a built-in main contactor. The unit is installed in marine, transport and off-grid systems where the battery works with an inverter, chargers and a load on one bus.

Description
The device collects data from all modules, balances the cells and, as soon as the parameters go outside safe limits, disconnects the chargers and the load with the contactor. The 12 V and 24–48 V versions are made for 400, 600 or 1000 A, the 72–96 V version for 500 A. Up to 48 RS modules or up to 96 LFP or HE modules are connected to the 24–48 V / 600 A version. This unit is powered from 18–58 V DC. Data exchange goes over a CAN Bus with M12 connectors. The IP22 case is designed for mounting in a dry compartment, and compliance with IEC-EN 62619 (ES-TRIN) is confirmed.
How to choose
The version is chosen by the battery voltage and the load current. The contactor current must cover the peak current of the inverter and consumers with a margin, so for powerful 24 V systems take the 1000 A version. For batteries above 96 V or RS strings of up to 900 V a Master HV with a contactor of up to 500 A is needed.

FAQ
What maximum current does MG Master LV switch?
The main contactor is rated up to 1000 A, in the 24–48 V / 600 A version up to 600 A.
How many modules can be connected to Master LV?
The 24–48 V / 600 A version serves up to 48 RS modules or up to 96 LFP or HE modules.
What supply voltage does the Master LV 24–48 V BMS require?
The unit in the 24–48 V version is powered from 18–58 V DC, that is, directly from the battery it monitors.
What communication interface does Master LV have?
CAN Bus with M12 connectors; through it the BMS receives module data and passes on the system status.
How does Master LV differ from Master HV?
Master LV works with low-voltage systems of 12–96 V and a current of up to 1000 A, while Master HV manages high-voltage strings of up to 900 V DC with a contactor of up to 500 A.
