Learn about Fronius Error Code 107, its causes, and how to resolve mains voltage issues.
Error Code 107 indicates that the mains voltage is outside the acceptable range for the inverter. This can lead to operational issues and requires immediate attention.
You can check your mains voltage using a multimeter to ensure it falls within the specified range. If it is outside the range, consult a qualified electrician.
The Fronius inverter triggers error 107 when it detects that the mains voltage is outside of the permissible range. This is a protective measure to prevent damage to the inverter and connected equipment. The inverter continuously monitors the input voltage through its internal measurement circuitry. If the measured voltage deviates from the allowable range (usually between 180V and 265V), it will initiate a shutdown to avoid potential electrical hazards or equipment failure. This can occur due to a variety of factors, including grid voltage fluctuations, improper inverter settings, or physical connection issues.
Homeowners may observe the inverter displaying an error 107 on its screen. This is often accompanied by a red LED indicator or alerts on the monitoring app, indicating that the inverter has shut down due to voltage issues. Additionally, there may be a noticeable drop in energy production, as the inverter will not operate under these conditions.
Always consult a licensed electrician or certified solar installer to diagnose and repair electrical issues to ensure safety and compliance with local codes.
Regularly schedule maintenance checks to ensure that all electrical connections are secure and free of corrosion. Monitor grid voltage trends and adjust inverter settings as necessary to accommodate local utility requirements. Consider installing surge protection devices to safeguard against voltage spikes.
