Learn about Solis Error Code UN-G-V, its meaning, causes, and solutions for troubleshooting.
The UN-G-V error indicates an issue with grid voltage measurements at the inverter terminals. This can affect the inverter's performance and connection to the grid.
To troubleshoot the UN-G-V error, check the grid voltage levels and ensure they are within the acceptable range. Inspect the inverter connections and wiring for any faults.
The UN-G-V error code signifies that the inverter has detected an abnormal grid voltage condition. Inverters are designed to operate within specific voltage ranges as per the National Electrical Code (NEC) and manufacturer specifications. When the grid voltage exceeds these predefined limits, the inverter will trigger a fault to protect both itself and the solar array. This fault can arise from various factors, including grid fluctuations, improper transformer settings, or internal faults within the inverter's voltage sensing circuitry.
Homeowners may observe the inverter's LED indicator flashing a specific pattern indicating fault, or the monitoring app may display an alert for the UN-G-V error code. Additionally, there may be a noticeable drop in energy production, potentially leading to reduced system performance.
Always prioritize safety when working on electrical systems. It is essential to engage a licensed electrician or certified solar installer for any troubleshooting or repairs to ensure compliance with electrical codes and safety standards.
To avoid encountering the UN-G-V error in the future, regularly inspect and maintain the solar system, ensuring all connections are secure and free from corrosion. Schedule periodic inspections with a certified solar technician to verify the integrity of the inverter and associated components. Additionally, stay informed about any changes to local utility grid standards that may impact system performance.
