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-tied voltage exceeds the
upper threshold and have
obtained the consent of the local
power operator, modify the
overvoltage protection threshold
through the mobile phone app,
SmartLogger, or NMS.
3. Check whether the peak power
grid voltage exceeds the upper
threshold.
