The new updated hardware for the BMS123

Starting from May, the new deliveries of the BMS123 contain a new hardware with a slightly modified circuit. Now the BMS123 main unit hardware is identical for the regular BMS123 (with a separate power supply) and the BMS123 Off-Grid, with power supply from the battery pack. Now all of the BMS123 units integrate the same hardware and functional difference is made by the internal software (firmware). There are no changes in the operation of the BMS for the new hardware versions.

In case you have any questions related to the function of the BMS, we suggest first installing the controller software to verify the proper function of the BMS main unit.
