Learn about Solis IGBT-OV-I error code, its causes, and solutions for overcurrent issues.
The IGBT-OV-I error code indicates an overcurrent condition in the inverter, often triggered by grid fluctuations. This can lead to system shutdown to protect the inverter.
To resolve the IGBT-OV-I error, check the grid stability and ensure proper connections. If the issue persists, consult the inverter manual or a qualified technician.
The IGBT-OV-I fault code indicates that the inverter has detected an overcurrent condition within its Insulated Gate Bipolar Transistor (IGBT) circuitry. This can occur when the current flowing through the inverter exceeds its rated capacity, often triggered by external factors such as grid instability or internal faults. When the inverter senses this overcurrent, it engages its protection mechanisms to prevent damage, which may include shutting down operations. Factors like RISO measurements, which assess insulation resistance, and ground fault detection protocols also play crucial roles in the inverter's ability to maintain safe operational parameters.
Upon encountering the IGBT-OV-I fault code, the inverter may display a solid red LED light, indicating an error state. Additionally, users may notice a drop in energy production reported through the monitoring app, often correlating with sudden fluctuations in grid voltage. The inverter may also enter a protective shutdown mode, ceasing to convert DC to AC power until the fault is resolved.
This troubleshooting process involves high voltage and current. It is essential to engage a licensed electrician or certified solar installer to perform any maintenance or repairs.
To prevent future occurrences of the IGBT-OV-I error, ensure that the inverter is installed in a well-ventilated area to prevent overheating. Regularly inspect and maintain the array and electrical connections to mitigate risks of short circuits or ground faults. Additionally, consider installing surge protection devices to safeguard against grid fluctuations and overvoltage conditions.
