62Fault

DEYE inverter error 62 (F62)

Reactor B phase over current

Also displayed as F62 on some models.

Faultthe inverter cuts its output and the red LED stays solid until the fault is cleared.

The exact meaning depends on your model:

What it means

Reactor B phase over currentOver-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

DRMs StopDRMs_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.

Cause: A Demand Response Mode (DRM0) command is active and has stopped the inverter.

How to fix it

  1. Check whether the DRM function is active
  2. Seek help from us if it cannot go back to the normal state after restarting the system.

What it means

DRMs0_stopDRM0 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

  1. Check whether the DRM function is active and disable it if unused.
  2. Seek help from Deye if the inverter does not return to normal after a system restart.
