Learn how to troubleshoot the Solis ISO-PRO error that occurs during rain.
The error may be due to moisture affecting the inverter's components, leading to malfunction. Inspect for water ingress and ensure proper sealing.
Check the inverter for any signs of water damage and ensure all connections are secure. If the problem persists, consult a professional technician.
The Solis ISO-PRO inverter is equipped with various protection mechanisms, including RISO measurement and ground fault detection. When moisture infiltrates the inverter or associated wiring, it can lead to decreased insulation resistance. The inverter continuously monitors for potential ground faults, which can occur when water creates unintended conductive paths. This situation can trigger protective shutdowns to prevent damage or safety hazards, causing the inverter to display error states. Understanding these mechanisms is crucial for diagnosing the root cause of the issue.
When it rains, users may observe the inverter displaying error codes on the monitoring app or via LED indicators. Common symptoms include sudden drops in energy production, blinking error lights, or complete shutdown of the inverter. Users might also notice unusual sounds from the inverter, indicating potential internal issues.
Always ensure that a licensed electrician or certified solar installer performs maintenance and troubleshooting on solar systems to adhere to safety standards and electrical codes.
To prevent this issue in the future, ensure that all electrical connections are properly sealed and that junction boxes are rated for outdoor use and resistant to moisture. Regular maintenance checks should include inspection of seals, connections, and the integrity of the inverter enclosure. Consider installing protective covers or enclosures to shield the inverter from direct exposure to rain and moisture.
