Learn about the Solis S5 inverter error code OV-G-V, its meaning, causes, and solutions.
OV-G-V indicates an over grid voltage condition, meaning the voltage exceeds safe levels. 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 for further diagnosis.
The Solis S5 inverter is designed to monitor grid voltage continuously. When the voltage exceeds the preset threshold, the inverter triggers the "OV-G-V" fault code to protect itself and the connected solar array. This fault can result from high utility grid voltage due to local grid fluctuations, which may exceed the inverter's maximum input voltage limits. The inverter employs voltage sensing circuitry to detect these conditions, and if the voltage remains above the threshold for a specified duration, it will cease operation to prevent damage.
Homeowners may observe the inverter's LED indicator flashing a fault code, specifically "OV-G-V," indicating an over grid voltage condition. Additionally, monitoring apps may display alerts regarding the inverter's inability to feed power into the grid, resulting in a noticeable drop in energy production.
Always consult a licensed electrician or certified solar installer for any troubleshooting or repairs to ensure compliance with local codes and safety standards.
To avoid future occurrences of the "OV-G-V" fault, regularly monitor grid voltage using a multimeter and ensure that the inverter settings are updated according to any changes in local utility regulations. Additionally, maintain clear access to the inverter and junction box for periodic inspections, and consider installing surge protection devices to mitigate transient voltage spikes.
