Generally, the inverter will be reconnected to
the grid after the grid returns to normal. If the
fault occurs repeatedly:
1. Measure the actual grid frequency, and con-
tact the local electric power company for solu-
tions if the grid frequency is beyond the set
range.
2. Check whether the protection parameters
are appropriately set via the App or the LCD.
3. Contact Sungrow Customer Service if the
preceding causes are ruled out and the fault
persists.

place.

preceding causes are ruled out and the fault
persists.
