What it means

Master address repeat — Two batteries on the communication bus are using the same (master) address.

Cause: In a multi-battery bank, more than one battery is set to the same address, so two units try to act as master on the bus.

How to fix it

Set a unique address on each battery (one master, the rest slaves) per the parallel-connection instructions, then power-cycle the bank.

Also applies to:GB-A

What it means

ALARM_ID_PCS_RS485_COMM_ERROR — The PCS RS485 communication is abnormal.

Cause: The RS485 link between battery and PCS is delivering corrupted or intermittent data - wiring, termination, or interface fault.

How to fix it

  1. Check the RS485 cabling, pin order and terminations between battery and PCS; restart both units.
  2. Contact Deye support if it persists.
