Learn about Solis IG-AD current measurement failures after power surges and how to troubleshoot.
Current measurement failures can occur due to power surges, faulty sensors, or internal circuit issues. It's essential to inspect the inverter for any visible damage.
Start by checking the inverter's display for error codes. Ensure all connections are secure and inspect for any signs of damage from the power surge.
The Solis IG-AD inverter relies on precise current measurement to optimize energy conversion from the solar array. A power surge can induce transient voltages that exceed the inverter's designed tolerances, potentially damaging the current sensing circuitry. This can trigger internal fault detection mechanisms, such as Ground Fault Detection or RISO measurement, which monitor for insulation resistance and ground faults. If these measurements fall outside acceptable limits, the inverter will halt operation to prevent damage.
After a power surge, the Solis IG-AD inverter may display an error message on the monitoring app indicating a current measurement failure. Users may observe abnormal LED patterns, such as blinking or solid red lights, and a significant drop in energy production, potentially leading to the inverter shutting down.
Always consult a licensed electrician or certified solar installer when performing any diagnostic or repair work on solar inverters.
To avoid future current measurement failures, consider installing surge protection devices (SPDs) at the service entrance and inverter locations. Regularly inspect and maintain all electrical connections, ensuring they are secure and free from corrosion. Additionally, monitor the inverter's performance through the app to identify any anomalies early.
