Learn how to troubleshoot the Solis OV-TEM fault and check the cooling fan operation effectively.
The OV-TEM fault indicates an overheating issue related to the inverter's cooling system. It is crucial to address this to prevent damage.
Ensure proper ventilation around the inverter and regularly check the cooling fan for obstructions or failures. Regular maintenance can help prevent overheating.
The OV-TEM fault is triggered when the inverter detects an over-temperature condition, which can occur due to various electrical and environmental factors. The inverter is equipped with thermal sensors that monitor internal temperatures. If the temperature exceeds the manufacturer's specified limits, the inverter automatically shuts down to prevent damage. This is often linked to insufficient cooling, which can be caused by a malfunctioning cooling fan or inadequate ventilation, leading to excessive heat buildup.
Homeowners may observe the inverter displaying an OV-TEM fault code on the monitoring app, accompanied by a shutdown of the system. LED indicators may flash a specific pattern indicating an overheating condition, and there may be a noticeable drop in energy production.
Always ensure that a licensed electrician or certified solar installer performs any troubleshooting or repairs to the inverter to prevent electrical hazards and ensure compliance with local codes.
To avoid future OV-TEM faults, ensure regular maintenance checks of the inverter, including cleaning air vents and verifying fan operation. Install the inverter in a well-ventilated area away from direct sunlight and heat sources. Consider implementing a thermal management system if the inverter operates in consistently high-temperature environments.
