About The photovoltaic inverter displays abnormal frequency
Abnormal Grid Frequency: The actual grid frequency falls outside the inverter’s acceptable range: The inverter automatically recovers if grid conditions stabilise. Check that grid frequency is within the acceptable range. If it isn’t, contact the power operator, but if it is, contact Huawei support. 313: Low Insulation Resistance.

If it occurs frequently, please check the grid voltage and the grid frequency if it is within the standard protection range of the inverter. If not, please check whether the AC side circuit breaker and the output cable are connected properly.
Troubleshooting: Check AC Grid Frequency: Make sure to verify the grid frequency and confirm if it lies within the acceptable range mentioned in the user guide. For additional help and investigation regarding solar inverter problems and solutions, get in touch with the manufacturer. 30. Error Code W020.
FAC (Frequency and Amplitude Control) failure in solar inverters refers to issues with managing the frequency and amplitude of the output AC (Alternating Current) waveform. Frequency in this context relates to how often the AC waveform cycles per second, measured in hertz, which needs to match the grid's frequency to ensure synchronization.
What do Sungrow Inverter Errors 039 and 032 Mean? A low insulation resistance error shows that there could be an earth fault in the PV cluster. For grid-connected inverters, the Sungrow inverter error code is 039, and 302 is for hybrid inverters. There can be a couple of things causing this issue, thus, they should all be checked.

6 FAQs about [The photovoltaic inverter displays abnormal frequency]
What is FAC failure in solar inverters?
FAC (Frequency and Amplitude Control) failure in solar inverters refers to issues with managing the frequency and amplitude of the output AC (Alternating Current) waveform. Frequency in this context relates to how often the AC waveform cycles per second, measured in hertz, which needs to match the grid's frequency to ensure synchronization.
What are common solar inverter faults?
Learn how to identify and repair common solar inverter faults like overcurrent, undervoltage, islanding, overheating, and faulty communication. What is a solar inverter and why is it important?
What happens if a PV inverter fails?
Increase the number of PV modules connected in series to the inverter. The protection for the DC circuit is triggered. This occurs if the inverter input accidentally disconnects, the three phases of the grid become unbalanced or if there’s a fault on a circuit in the inverter. Turn off the AC output switch, then the DC input switch.
Do all inverter error codes mean a serious problem?
The different inverter brands have an array of unique error codes. True, not all inverter error codes mean a serious problem. Some are simply notifications, and some are automatically rectified.
What causes a solar inverter to fail?
Inverter failure can be caused by problems with the inverter itself (like worn out capacitors), problems with some other parts of the solar PV system (like the panels), and even by problems with elements outside the system (like grid voltage disturbances). An inverter failure is when the inverter develops faults that cause improper functioning.
How to maintain a faulty solar inverter display?
To maintain a faulty solar inverter display, you can proceed with the following steps: Begin with turning off the input PV switch on the photovoltaic inverter side. Next, disconnect the PV input DC switch and finally, switch off the battery switch.
