Suggestion
1.If the alarm occurs occasionally, the power grid may be abnormal temporarily. The inverter automatically recovers after detecting that the power grid becomes normal.
2.If the alarm occurs frequently, check whether the power grid frequency is within the allowed range. If not, contact the local power operator. If yes, upgrade the firmware to latest version.
3. If the problem remains, modify the power grid overfrequency\underfrequency protection threshold after obtaining the consent of the local power operator.
