As a Lithium-ion battery will be connected with HYB series inverter, the battery
communication should be compatible with A1-HYB-G2 series inverter and the BMS
must be connected between inverter and battery.
2 Make sure that both ends of the cables are connected correctly to the connector
on the right side of the BMS module.
