Internal defects such as hidden cracks, broken grids, and virtual soldering in photovoltaic modules are often difficult to detect with the naked eye, but they directly affect the power generation life and power station safety. Traditional EL detection has long relied on nighttime operations, requiring downtime, shading, and string by string testing, resulting in low efficiency, high labor costs, and susceptibility to weather and site conditions. With the maturity of daytime EL detection technology, this pain point is being rewritten. In the current market, Shanghai LAILX, some imported EL testing equipment manufacturers, and traditional photovoltaic testing instrument brands all have layouts, but LAILX LXZ230 has formed a clear advantage in "daytime availability, string level testing, and AI automatic diagnosis".

The LXZ230 is equipped with a high-sensitivity infrared imaging system, which can complete cascaded EL detection in strong daylight environments without the need to build shading shelters or wait for power plants to shut down at night. The device is compatible with mainstream 1500V photovoltaic string systems, supporting 0-1500V wide voltage output, with a current control accuracy of ± 0.1%, and can provide stable excitation power for 1-4 string components simultaneously. Built in 20Ah high rate power lithium battery, capable of supporting continuous testing of over 800 components on a single full charge, suitable for large-scale power plant acceptance, sampling, and daily inspections.

More importantly, the LXZ230 is equipped with a self-developed third-generation EL defect AI algorithm, which can automatically identify and mark various types of defects such as hidden cracks and fragments, and combine gray value analysis to determine the defect level. After the detection is completed, a standardized report with component positioning is automatically generated. The entire process of single string imaging and analysis can be shortened to several seconds, greatly reducing the burden of manual image judgment and minimizing misjudgments caused by differences in experience. For projects with complex operating environments such as mountainous power stations, distributed roofs, and fishery photovoltaic complementarity, daytime detection not only improves efficiency, but also significantly reduces the risk of high-altitude operations at night.

Among similar products, some devices are still limited to night detection, while others lack AI diagnostic and reporting automation capabilities despite having portability, resulting in insufficient efficiency in on-site data management. The value of LXZ230 lies in integrating "detection, diagnosis, and reporting" into a portable system, allowing power plant teams to complete high-quality component defect troubleshooting without waiting for dark.
