Learn about the Solis S5 inverter error code OV-G-V, its causes, and solutions.
OV-G-V indicates Over Grid Voltage, meaning the voltage exceeds safe limits. This can lead to inverter shutdown to protect the system.
Check the grid voltage levels and ensure they are within specifications. If the issue persists, consult a professional technician.
The Solis S5 inverter is designed to monitor grid conditions continuously. When the inverter detects a voltage level exceeding its operational thresholds, it triggers the "OV-G-V" fault code. This is a protective measure to prevent damage to the inverter and connected solar array components. The inverter relies on accurate voltage readings from its internal voltage transformer. If these readings exceed the maximum allowable limits set by the manufacturer, the inverter will disconnect from the grid to protect itself and maintain safe operation.
Homeowners may notice the Solis S5 inverter displaying the fault code "OV-G-V" on its LED indicator. This may be accompanied by a drop in energy production visible on the monitoring app, indicating the inverter has shut down due to over grid voltage conditions. The LED may blink in a specific pattern, signaling the fault status.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical components to ensure safety and compliance with local codes.
To avoid future occurrences of the "OV-G-V" fault, ensure regular maintenance of the solar array and inverter. Schedule periodic inspections to check for loose connections, corrosion, and grounding integrity. Additionally, stay informed about local grid conditions and any utility advisories that may affect voltage levels.
