As the core component of power generation in power plants, photovoltaic modules have internal defects such as hidden cracks, broken grids, and virtual welding, which are the core causes of power generation attenuation and premature module scrapping. These hidden defects cannot be recognized by the naked eye and require precise detection by professional equipment. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of photovoltaic defect detection for many years. It has launched the LXG50 portable EL detector, which is characterized by high-resolution imaging, intelligent defect recognition, all-weather detection capability, and portable design. It has become the "golden eye" for internal defect detection of photovoltaic modules, providing core guarantees for quality control, operation and maintenance improvement of photovoltaic power plants, and safeguarding the high-quality development of the photovoltaic industry.

The LXG50 portable EL detector is a benchmark product specially designed by LAILX for full scene defect detection of photovoltaic modules. It adopts advanced electroluminescent imaging technology to accurately capture micro defects inside photovoltaic modules, breaking the limitations of traditional detection equipment that cannot identify hidden faults. The device is equipped with a 26 million level high-sensitivity infrared camera, paired with a full frame industrial grade CMOS infrared chip and a 17mm/95 ° angle patented infrared lens. The imaging accuracy is greater than 0.2mm/pixel, and the sensitivity is extremely high. It can detect subtle hidden cracks with a width less than 0.2 μ m, clearly presenting more than ten types of internal defects such as broken grids, fragments, virtual soldering, hot spots, PID attenuation, etc. The imaging quality is clear, the details are sharp, and there is no noise interference, providing reliable visual support for accurate defect identification. Whether it is crystalline silicon modules, thin-film modules, or CIGS modules, they can be adapted for testing, covering mainstream module types in the photovoltaic market, and have strong universality.

24/7 detection capability, breaking through environmental limitations and adapting to various work scenarios. The traditional EL detector can only be used at night or in low light environments, with limited detection time and low efficiency. However, the LXG50 is equipped with the Lexus patented full-time dark light autofocus system, which does not require the assistance of a rangefinder. It can quickly and accurately focus under various lighting conditions such as strong light during the day, weak light at night, and cloudy days, and can complete single component imaging in 3-10 seconds, achieving 24-hour uninterrupted detection and completely breaking the limitations of time and environment. During daytime inspection, the device can effectively block strong light interference and clearly display internal defects of components; During nighttime inspections, there is no need for additional lighting equipment. High sensitivity infrared cameras can capture clear images, greatly improving the flexibility and efficiency of power station inspections and shortening the operation and maintenance cycle.

Integrated portable design, balancing practicality and convenience, suitable for complex outdoor scenes. The LXG50 machine adopts a lightweight architecture, with a lightweight and portable body, matched with a high-strength aluminum alloy portable case, which is shockproof, waterproof, and drop proof. It can be easily carried to various outdoor photovoltaic power plants such as roofs, mountains, deserts, etc., and can be transported, deployed, and operated by a single person without the need for professional team assistance, greatly reducing labor costs and operational barriers. The equipment is equipped with adjustable tripods to meet the detection needs of components at different heights. It can be deployed quickly and securely, avoiding image blurring; Adopting a wireless connection design, there is no need for complicated wiring between the camera, power supply, and control terminal, making the operation simple and efficient, reducing the risk of outdoor wiring failures. At the same time, the body adopts a waterproof and dustproof design, which can adapt to temperature environments ranging from -10 ℃ to 50 ℃, and is not afraid of harsh outdoor weather, ensuring stable testing work.

Empowered by intelligent technology, making detection more efficient and data management more intelligent. The LXG50 is equipped with a programmable 2-in-1 detection power supply, which can wirelessly control power parameter adjustment and power on/off settings through a dedicated EL detection APP. The power supply is stable, safe and reliable, meeting the detection needs of outdoor scenarios without fixed power sources. The APP supports Android and iOS systems, with a simple and intuitive interface that beginners can quickly get started with; Equipped with AI automatic defect recognition function, it can intelligently mark the location of hidden cracks, broken grids and other defects, automatically generate defect reports, without the need for manual inspection one by one, greatly improving the efficiency and accuracy of defect recognition. At the same time, it supports real-time uploading of detection images and data to the Lexus Photovoltaic Cloud Platform, enabling online data storage, analysis, and sharing, facilitating remote team collaboration, historical data tracing, and assisting in digital control of power plant operation and maintenance. In addition, the device supports one click image export and automatic report generation, with customizable formats to meet the needs of third-party inspection report issuance and power plant operation and maintenance file retention.

Excellent safety performance, building a strong defense line for high-voltage detection safety. The LXG50 is equipped with overvoltage, overcurrent, and short-circuit protection functions, ensuring stable power output and effectively avoiding safety accidents caused by operational errors or component failures; Adopting insulation protection design to eliminate the risk of electrical leakage and ensure the safety of operators. At the same time, the equipment is adapted to the detection requirements of 1500V high-voltage photovoltaic string, compatible with mainstream high-voltage systems, and has strong universality. It can complete high-voltage component detection without additional accessories, reducing the cost of use.

With its hardcore performance and reliable quality, the LXG50 portable EL detector has been widely used in photovoltaic module production quality inspection, power plant grid connection acceptance, daily operation and maintenance defect investigation, third-party testing institutions and other scenarios, covering major photovoltaic power plants in China and receiving unanimous praise from industry customers. In the future, LAILX in Suzhou will continue to focus on innovation in photovoltaic defect detection technology, continuously optimize product performance, upgrade AI recognition algorithms, and launch more efficient, intelligent, and portable detection equipment to help improve the quality, efficiency, safety, and stable operation of the photovoltaic industry.
