What it means
All hardware failure synthesis — Aggregate flag raised when hardware protection faults occur in combination. The manual notes this code has hardly ever appeared in the field.
Cause: Several hardware protection signals tripped together; the inverter raises this synthesized (aggregate) hardware-failure flag.
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
All hardware failure synthesis — Aggregate flag for combined hardware protection faults; on these models it can be triggered by hot-plugging the WiFi logger.
Cause: Plugging the WiFi logger in while the inverter is running raises F19; otherwise it is the aggregate flag for combined hardware protection trips.
How to fix it
Restart the inverter or perform a factory reset; if the error still exists, contact your installer or Deye service.

What it means
AFE-OCDL/OCD1/OCD2 — Hardware over-current discharge protection (OCD level 1/2/latch) from the BMS analog front end tripped.
Cause: The analog front-end chip detected discharge current above its hardware protection levels - a heavy surge or a short circuit on the battery terminals.
How to fix it
- 1Disconnect the load, inspect the DC cabling for shorts, and restart the battery.
- 2If the protection trips again immediately, contact Deye support.

What it means
ALARM_ID_SOC_LOW_LEV_2 — The SOC is too low.
Cause: State of charge fell below the allowed lower limit - the battery was discharged without timely recharging.
How to fix it
Recharge the battery promptly from PV or grid; check the PCS discharge cut-off settings so the bank is not run this low again.
