Learn about the SunPower Maxeon Temperature Sensor Error, its meaning, causes, and solutions.
The error may be caused by a malfunctioning temperature sensor or wiring issues. It's important to check connections and sensor functionality.
Start by inspecting the sensor and its connections. If the issue persists, consult the user manual or contact support for further assistance.
The SunPower Maxeon inverter utilizes a temperature sensor to monitor the operational temperature of the unit, ensuring it remains within safe limits. If the inverter detects an abnormal temperature reading—either too high or too low—it triggers a fault to prevent damage. This can occur due to improper insulation resistance (RISO) measurements, which may indicate a ground fault or other electrical issues. The inverter also monitors grid frequency limits; if these are exceeded, it may lead to thermal management errors.
Homeowners may notice an alert on the monitoring app indicating a temperature sensor error. The inverter's LED may exhibit a steady red light, signaling a fault condition. Additionally, there may be a noticeable drop in energy production, which can be observed through daily performance metrics.
Always ensure that any diagnostics or repairs are conducted by a licensed electrician or certified solar installer to prevent electrical hazards.
To avoid future temperature sensor errors, ensure regular maintenance is performed on the inverter, including cleaning and inspection of the air intake areas. Additionally, monitor the inverter’s performance regularly through the app and address any alerts promptly. Keeping the inverter shaded from excessive heat and ensuring it has adequate airflow can also help prevent overheating.
