B000 on master and first slave inverter
Good day,
3 X 12kw sunsynks in parallel. 4X Freedom Won 10/8kw batteries in parallel. Comms cables between batteries where cables enter on can port and loops to next battery from bus to can. Termination block on last battery bus port. Comms between master inv to master battery from BMS port to CAN on master battery. Worked normally for 8 months.
Now master a first slave displayes code B000 and master online light goes off. If you change battery type to AGM V, everything normal again. Should be comms problem but cant find the fault code.
