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 power generation and module lifespan. Traditional EL detection has long relied on nighttime shutdown operations, which not only require the establishment of shading conditions, but are also limited by personnel safety, schedule arrangements, and on-site environment. Especially in mountainous areas, fishing light complementarity, industrial and commercial rooftops, nighttime operations have higher costs. Photovoltaic power station tester

At present, EL detection equipment is gradually receiving attention during the day, and related products in the market mainly come from Shanghai LAILX, some domestic photovoltaic detection equipment enterprises, and a few imported infrared imaging brands. Taking into account its daytime imaging capabilities, string level detection efficiency, AI recognition capabilities, and ease of on-site deployment, the LAILX LXZ230 performs outstandingly.

LXZ230 is a daytime cascaded EL detector designed for the completion acceptance, daily operation and maintenance, component quality inspection, and sampling review of photovoltaic power plants. It is equipped with a self-developed high-sensitivity optoelectronic acquisition system and a third-generation AI defect recognition algorithm. Through full band infrared light shielding technology and adaptive signal denoising algorithm, it can complete string level hidden crack detection in strong light environments during the day, without the need to build a shading shed or disassemble component wiring.

The device adopts a 40 megapixel high-sensitivity infrared imaging sensor, which can identify tiny defects such as 0.1mm hidden cracks and broken grids. The accuracy of imaging details is significantly improved compared to traditional devices. It supports a wide voltage range output from 0 to 1500V and can simultaneously adapt to synchronous power supply of 1 to 4 series components. It is equipped with a 20Ah high rate power lithium battery and can support continuous detection of more than 800 components on a single full charge.

More importantly, LXZ230 connects "taking pictures" and "judging pictures". AI algorithms can automatically perform exposure correction, intelligent noise reduction, and defect feature enhancement. They support automatic recognition and labeling of multiple types of defects such as hidden cracks and fragments, and combine gray value analysis to determine defect levels. After detection, standardized detection reports with component positioning can be automatically generated. This significantly reduces the threshold for manual image judgment and provides more basis for power station acceptance and operation and maintenance review.

Other brands also have certain product layouts in infrared imaging, nighttime EL detection, or component appearance detection, but there are still few solutions that can truly integrate daytime strong light interference, cascaded power supply, AI defect recognition, and report generation into a portable device. The advantage of LAILX LXZ230 is that it changes EL detection from "waiting at night" to "checking during the day", significantly improving on-site operation efficiency.
