About Photovoltaic inverter fan abnormality
Abnormal sounds from inverters can normally be categorized into the following categories: Fan noise: This often occurs when the inverter is running at high power or full power, and the fan needs to dissipate heat. If the fan isn't operating as it should, it will produce a more distinguishable sound – when prolonged this may affect the working .

Usually, the place where the inverter is installed has insufficient ventilation, the inverter is exposed to the sun, and the inverter fan is abnormal. To solve this problem, it is first necessary to ensure that the inverter installation site is ventilated to prevent the inverter from being exposed to the sun.
1.Check whether the internal fan of the inverter is abnormal and does not start; 2. Restart the inverter, if it is still not ruled out, please contact the manufacturer's customer service.
If the inverter displays an alarm code such as "Fan Abnormal" or "Over-Temperature Protection", it is necessary to check whether the inverter fan is running or if there is debris blocking the ducts. Clean up the foreign matter and clear the alarm code.
If your inverter is running hot, it would mean that the fan is not working properly, the inverter has poor ventilation or is overloaded, or the ambient temperature is too high. Power generation creates heat, so your inverters will get warm.

6 FAQs about [Photovoltaic inverter fan abnormality]
What are the causes of photovoltaic inverter failure?
Serious device fault: It includes excessively high temperature, over-current protection, bus voltage abnormality, delay abnormality, drive abnormality, auxiliary power source abnormality, etc. When the Photovoltaic inverter encounters hardware or software failure, it can not keep working and will stop.
How do I fix a faulty inverter fan?
Check whether the internal fan of the inverter is abnormal and does not start; try to restart the inverter. Check whether the external fan is abnormal and does not start; try to restart the inverter; refer to the manual to replace the external fan/clean the fan. Restart the inverter and replace the fuse referring to the manual.
What if a solar inverter is not working?
One of the fans is defective, causing the temperature in the system to be too high. Clear air inlets, keep the ambient temperature as low as possible.Also, engage the services of a professional for fan replacement. Solar Net communication is not possible. It happens when the inverter address is issued twice.
How common is the general failure of solar PV inverter?
The commonness of the general failure: The general failure will not cause serious impact on personnel safety and solar PV inverter safety. The situation will not become worse immediately and can be solved a little later. But it does not mean that the general failure does not need to be solved.
What happens if the PV inverter fails?
When some failures appear, the PV inverter only gives alarm and shows red light, but it will not stop immediately. When some other failures appear, the solar inverter will stop immediately but the stop time is different. Why? When people are ill, the illness degree will be different.
Why is my inverter fan so noisy?
Inverter fans can become noisy if the fan motor becomes worn due to overuse, when the load placed on the inverter is too high, or when the temperature in the inverter remains too high despite the fan running at full speed. Dust on the fan blades or air intake also causes the fans to be noisy.
