Troubleshooting Suggestion
1. Check whether the grid
connection voltage exceeds the
upper threshold. If yes, contact
the local power operator.
2. If you have confirmed that the
grid connection voltage exceeds
the upper threshold and
obtained the consent of the
local power operator, modify the
overvoltage protection
threshold.
3. Check that the peak grid voltage
does not exceed the upper
threshold.
