With the widespread adoption of solar photovoltaic (PV) systems, ensuring their efficient and stable operation is essential. However, during long-term operation, PV systems may encounter common faults.
Check the DC voltage at the inverter input to ensure proper connection between PV modules and the DC combiner box. Monitor the inverter screen or online monitoring system for fault codes and refer to the user manual for troubleshooting. Ensure the inverter is installed in a well-ventilated environment to prevent overheating. 3.
By comparing the simulation results with the actual parameters of the PV module in reality, we can determine whether the PV module has faults. This fault detection method based on mathematical model not only improves the accuracy of fault detection, but also provides strong support for the maintenance and optimization of PV system. Fig. 5.
In the future, with the continuous development of artificial intelligence technology, especially the application of big data analysis, image processing technology and self-supervised learning methods, the PV fault diagnosis system will be able to achieve more accurate and rapid fault detection and diagnosis.
