Only perform checks that are safe and within your knowledge. Do not open electrical equipment.

1. Note the fault code

Record the exact code shown on the inverter display or monitoring platform. A photo of the screen can also help our support team.

2. Check the system status

Confirm whether the inverter is powered on and whether the battery and grid/PV sources appear normal.

3. Check monitoring

If connected to Deye Cloud or another supported monitoring platform, check whether the system is online and whether additional alarms appear.

4. Still having the issue?

If the fault remains, open a support ticket with the fault code, equipment model and a short description.
