In the event of receiving Alarm ID 013 through the App on a frequent manner, it is imperative to initiate the necessary corrective measures to counter this abnormal grid connection behavior.
The subsequent actions to be taken include:
Grid abnormal (Code 013)
Fault name | Grid abnormal (fault code: 013) |
Fault type | Failure shutdown |
Fault condition | Before the inverter is connected to the grid, the measured voltage and frequency values of the grid are not within the set ranges. |
Steps and method of troubleshooting | 1. Check whether the AC wiring is secure, including the AC distribution cabinet wiring. 2. Check whether the country selection is correct (the grid frequency is 50Hz or 60Hz). 3. Check whether the set voltage and frequency of the detection function are correct before grid connection. 4. Measure the AC voltage of the AC output and compare the measured value with the displayed voltage. If the measured voltage is abnormal, please check whether the parameter is set within the detection range before grid connection; If the measured voltage is normal and the displayed voltage is wrong, it can be inferred that the sampling is abnormal. It is recommended to replace the inverter. |
