Learn how to troubleshoot and resolve Goodwe Error Code 17 related to DC sensor abnormalities.
Error Code 17 indicates a DC sensor abnormality in the Goodwe inverter, which can affect performance.
To diagnose DC sensor issues, check the wiring connections and inspect the sensor for damage or faults.
Error 17 signifies a DC sensor abnormality, which typically arises when the inverter detects irregularities in the DC voltage or current inputs. This could occur due to improper insulation resistance (RISO) measurements, where the inverter's ground fault detection mechanisms identify potential leakage currents. Additionally, if the voltage from the solar array exceeds predefined thresholds, the inverter may trigger this fault to prevent damage. The inverter's internal logic relies on accurate readings from the DC sensors to ensure safe operation and optimal energy conversion.
Upon encountering Error 17 on a Goodwe inverter, users may observe the LED indicators flashing in a specific pattern, typically indicating a fault. Monitoring apps may display alerts regarding sensor abnormalities, and there may be a noticeable drop in energy production metrics.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical issues to ensure compliance with safety standards and local codes.
To prevent future occurrences of 17, regularly inspect and maintain all electrical connections, ensuring they are tight and free from corrosion. Schedule routine insulation resistance testing to identify potential ground faults early. Additionally, ensure that the inverter's firmware is kept up to date to mitigate software-related issues.
