Steps and method of troubleshooting

Normally the inverter will re-connect to the grid after the internal temperature returns to normal, if the fault recurs:

1. Check whether the inverter is directly exposed to sunlight. If so, take some shading measures.
2. Check and clean the air ducts.
3. Check whether there is 070 (fan anomaly) alarm via the APP or the LED. If so, replace the fans.

If the fault is not caused by the foregoing reasons and still exists, please contact Sungrow Service.
