Hello Everyone

Have a luxpower 5kva inverter with two 100amp  elfbulb batteries which have been working well for 14 months until late december then on the lcd screen the BMS anolog showed TCP failure . I have switched off batteries right away and have trying to figure out why TCP failure on BMS . Advice from factory has been hard. Question should the BMS be replaced. There is a scp fuse on bms board but where and Does Anyone had this happen to their Solar system

Any advice would be appreciatted
