What it means
V phase grid current DC component over current — The DC component of the V-phase grid current is too high. The manual notes this code has hardly ever appeared in the field.
Cause: The DC component of the V-phase grid current exceeds the allowed 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
Grid Current DC Component High (Phase V) — AC_V_GridCurr_DcHigh_Fault - the DC component of the phase-V grid current is too high.
Cause: The DC component in the grid current of phase V exceeded the limit.
How to fix it
Restart the inverter 3 times and restore the factory settings.

What it means
Pre charge fail — The precharge circuit could not bring the output/bus voltage up.
Cause: A short circuit or a very large capacitive load on the battery terminals, or a failed precharge resistor, prevented the bus from precharging.
How to fix it
- 1Disconnect the DC cables and check for shorts; confirm the connected inverter is a supported type.
- 2Reconnect and restart; if precharge still fails, contact Deye support.

What it means
ALARM_ID_MBMS_NTC_BREAKLINE_ERROR — Temperature collection of the BMS connector is abnormal (NTC open circuit).
Cause: The NTC temperature sensor line on the BMS connector is broken or disconnected.
How to fix it
- 1Restart the system.
- 2If the fault persists, the sensor line needs service - contact Deye support.
