The Battery Management System (BMS) is the brain of the battery, focusing on monitoring, protecting, and optimizing battery performance. It continuously tracks essential parameters like voltage, current, temperature, and state of charge (SOC), ensuring the batteries operate within safe limits.
[pdf] For the BMS to communicate correctly with the inverter the battery must be set to the correct Modbus protocol. This can be done on the battery settings page. The inverter manuals have a list of compatible batteries detailing their Modbus protocol and whether they use CAN or RS485 communications.
