Off-grid overvoltage (Code 064)
Fault name | Off-grid inverter overvoltage fault (fault code: 064) |
Fault type | Fault |
Fault condition | The effective value of inverter voltage is higher than the protection value under off-grid normal operation |
Steps and methods of troubleshooting | Use a multimeter to measure the off-grid port voltage and compare it with the displayed value. If there is a big difference, it is judged that the sampling is abnormal, and it is recommended to replace the inverter. |
Off-grid low frequency (Code 065)
Fault name | Off-grid port inverter low frequency fault (fault code: 065) |
Fault type | Fault |
Fault condition | The inverter frequency value is lower than the normal range under off-grid normal operation |
Steps and methods of troubleshooting | If the fault remains, it is recommended to replace the inverter. |
Off-grid high frequency (Code 066)
Fault name | Off-grid port inverter high frequency fault (fault code: 066) |
Fault type | Fault |
Fault condition | Inverter frequency value exceeds the standard under off-grid normal operation |
Steps and methods of troubleshooting | If the fault remains, it is recommended to replace the inverter. |
