Learn about Sungrow Error Code 106, its causes, and how to troubleshoot fan failure issues effectively.
Error Code 106 indicates a fan failure in the Sungrow inverter. This can lead to overheating and reduced performance.
To fix a fan failure, check for obstructions, ensure proper power supply, and consider replacing the fan if necessary.
The Sungrow inverter utilizes an internal cooling fan to maintain optimal operating temperatures. When the inverter detects that the fan is not functioning correctly, it triggers fault 106 to prevent overheating, which could lead to permanent damage. This fault is a protective measure, as excessive heat can affect the inverter's efficiency and longevity. The inverter continuously monitors the fan's operational status, and if it does not receive the expected feedback, it interprets this as a fault condition.
Homeowners may observe a fault 106 displayed on the inverter's screen, accompanied by a steady red LED indicator. Monitoring apps may also report reduced energy production or system shutdown alerts, indicating that the inverter is not functioning correctly. Additionally, users may notice abnormal noise levels if the fan is attempting to operate but is malfunctioning.
Always consult a licensed electrician or certified solar installer when troubleshooting or performing maintenance on solar inverters to ensure safety and compliance with local electrical codes.
To prevent future occurrences of fault 106, regularly clean the inverter's exterior and ensure that the fan intake is free from obstructions. Schedule routine maintenance checks to inspect electrical connections and the fan's operational status. Consider installing the inverter in a shaded or temperature-controlled environment to avoid overheating.
