Learn about Solis Error Code 12Power-FAULT, its causes, and how to resolve it effectively.
The 12Power-FAULT error indicates a failure in the 12V power supply of the inverter. This can lead to system shutdown or reduced performance.
To troubleshoot the 12Power-FAULT error, check the power supply connections and ensure they are secure. If the issue persists, consider replacing the power supply unit.
The Solis 12Power inverter triggers the 12Power-FAULT code when it detects a failure in its power supply circuit. This can occur due to insufficient input voltage from the PV array, which may fall below operational thresholds due to various factors such as shading or soiling. The inverter's built-in ground fault detection mechanism may also activate the fault code if it senses an anomaly that could indicate a short circuit or leakage current. The inverter continuously monitors grid frequency limits, and any deviations outside acceptable ranges can also prompt a fault response to protect both the inverter and the connected array.
Homeowners may observe the inverter's LED indicator flashing a specific fault pattern or displaying an error message on the monitoring app. Additionally, there may be a noticeable drop in energy production, with real-time monitoring showing zero or significantly reduced output.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical issues. Working with high-voltage systems can be dangerous and should only be handled by qualified licensed technicians.
Regular maintenance of the solar array, including cleaning and inspection of connections, can prevent many issues leading to the 12Power-FAULT code. Additionally, ensure that the inverter’s firmware is updated to the latest version and that all settings are correctly configured during system. Monitoring system performance regularly can help identify potential problems before they escalate.
