What it means
Reactor B phase over current — Over-current through filter reactor phase B. The manual notes this code has hardly ever appeared in the field.
Cause: The current through filter reactor phase B exceeded the over-current limit.
How to fix it
Restart the inverter; if the code persists after the restart, contact your installer or Deye service and provide the inverter serial number, the installation date and the displayed error code.

What it means
Reactor B phase over current — Over-current through filter reactor phase B.
Cause: The current through filter reactor phase B exceeded the over-current limit.
How to fix it
Restart the inverter; if the fault is not ruled out, contact the installer or the manufacturer's customer service.

What it means
DRMs Stop — DRMs_Stop - the inverter has been stopped by a demand response (DRM) command.
Cause: A Demand Response Mode (DRM) command is active and has stopped the inverter.
How to fix it
Check whether the DRM function is active.

What it means
DRMs0 Stop — DRMs0_stop - the inverter has been stopped by a demand response (DRM0) command.
Cause: A Demand Response Mode (DRM0) command is active and has stopped the inverter.
How to fix it

What it means
DRMs0_stop — DRM0 stop (demand response, Australia).
Cause: The DRM0 demand-response signal commanded the inverter to stop, or the DRM function is enabled where it is not in use (the DRM function is for the Australia market only).
How to fix it
- 1Check whether the DRM function is active and disable it if unused.
- 2Seek help from Deye if the inverter does not return to normal after a system restart.
