Learn how to troubleshoot clicking noises and red fault lights in Aero-Sharp Inverters.
A clicking noise in an inverter often indicates a fault or malfunction. It may be due to internal issues or external factors affecting performance.
To reset your Aero-Sharp Inverter, turn off the power supply, wait for a few minutes, and then turn it back on. This can help clear minor faults.
The clicking noise and red fault light are indicative of the inverter's internal safety protocols being triggered. Inverters are designed to protect both the system and the utility grid, engaging fault detection mechanisms when electrical anomalies are detected. This could involve insulation resistance measurement (RISO) failures, where the inverter assesses the integrity of the wiring insulation. If the RISO measurement falls below acceptable thresholds, the inverter will cease operation to prevent potential damage or safety hazards. Ground fault detection may also activate if a short circuit or leakage current is identified, further prompting the inverter to enter a fault state. Additionally, grid frequency limits and overvoltage conditions can cause the inverter to disconnect to protect both itself and the connected array.
The Aero-Sharp inverter exhibits a persistent clicking noise accompanied by a red fault light indicator. Users may also notice a drop in energy production on the monitoring app, with alerts indicating a fault condition. The clicking noise is often rhythmic and may correlate with the inverter's attempts to restart or re-engage the grid connection.
Always consult a licensed electrician or certified solar installer before performing any troubleshooting or maintenance on solar inverters and associated electrical systems.
To avoid future occurrences of clicking noises and fault lights, ensure regular maintenance of the solar array and inverter. This includes periodic inspections for moisture or physical damage, verifying electrical connections, and cleaning the inverter’s ventilation areas. Implementing a proactive monitoring system for string voltages and environmental conditions can also help in early detection of issues.
