In the event of receiving Alarm ID 009 through the App, it is imperative to initiate the necessary corrective measures to counter Grid Underfrequency.
The subsequent actions to be taken include:
Grid underfrequency (Code 009)
Fault name | Grid underfrequency (fault code: 009) |
Fault type | Failure shutdown |
Fault condition | The minimum frequency of the grid is lower than the set underfrequency-protection-value and the duration exceeds the set time. |
Steps and method of troubleshooting | 1. Check whether the country selection is correct (the grid frequency is 50Hz or 60Hz). 2. Check whether the set value of inverter underfrequency protection is correct. 3. Check whether the displayed frequency is consistent with the actual value. If the two values are different, it can be inferred that the sampling is abnormal. It is recommended to replace the inverter. |
