Learn about the Sungrow Temperature Sensor Error, its causes, and how to resolve it effectively.
A Temperature Sensor Error typically indicates that the inverter is detecting abnormal temperature readings. This could be due to a faulty sensor or overheating components.
To troubleshoot, check the sensor connections and ensure the inverter is not overheating. If the issue persists, consider contacting a technician for further diagnosis.
The inverter triggers a Temperature Sensor Error primarily to protect itself and the solar array from potential overheating. The inverter's internal logic continuously monitors the temperature of critical components via the temperature sensor. If the sensor detects temperatures outside the acceptable range, it may indicate overheating due to environmental factors or internal issues. This fault can also arise from improper insulation resistance measurement (RISO) or ground fault detection mechanisms that signal potential hazards, prompting the inverter to shut down to ensure safety.
When your Sungrow inverter displays a Temperature Sensor Error, you may observe specific visual cues such as a flashing LED indicator or an alert in the monitoring app indicating a fault. Additionally, you may notice a drop in energy production, as the inverter may limit output to prevent damage.
Always consult a licensed electrician or certified solar installer for troubleshooting and repairs to ensure compliance with safety regulations.
To avoid future Temperature Sensor Errors, ensure regular maintenance checks are performed on the inverter and its components. Keep the inverter area clear of debris to promote adequate ventilation. Additionally, verify that all wiring and connections adhere to NEC standards during system and any subsequent repairs.
