As the core power generation unit of a power station, photovoltaic modules have internal defects such as hidden cracks, broken grids, virtual soldering, PID attenuation, and hot spots, which are invisible killers that lead to decreased power generation efficiency, premature aging of components, and even safety accidents. Traditional appearance inspection methods are difficult to capture small internal defects, but the LXG50 portable EL detector independently developed by LAILX in Suzhou, with four core advantages of 30 million level high-definition imaging, AI intelligent defect recognition, all-weather rapid detection, and portable design, has become the "sharp eye" for internal defect detection of photovoltaic modules, providing efficient, accurate, and convenient solutions for quality control throughout the entire life cycle of photovoltaic power plants.

Electroluminescence (EL) imaging technology is currently the most effective means of detecting internal defects in photovoltaic modules. By applying a forward bias voltage to the module, it excites the module to emit infrared light, and then captures the image with a high-sensitivity infrared camera, which can clearly present the subtle defects inside the module. The LAILX LXG50 portable EL detector is designed specifically for on-site inspection of photovoltaic power plants, breaking through the limitations of traditional EL detectors such as large size, heavy weight, complex operation, and dependence on dark environments. It achieves "lightweight, intelligent, all-weather, and high-efficiency" detection, completely revolutionizing the photovoltaic defect detection mode and solving the industry's long-standing detection pain points.

High definition infrared imaging system accurately captures micrometer level defects. The LXG50 is equipped with a 30 megapixel full frame industrial grade CMOS infrared chip, paired with a 17mm/95 ° wide-angle infrared lens, with an imaging accuracy of over 0.2mm/pixel. It can clearly capture fine cracks with a width of less than 0.2 μ m, accurately identify more than ten internal defects such as hidden cracks, broken grids, fragments, virtual soldering, hot spots, PID attenuation, etc. The imaging clarity and defect recognition rate are at the forefront of the industry. Compared to traditional EL detectors, LXG50 has a wider imaging range, and a single image can cover the entire photovoltaic module without the need for multiple shots and splicing, greatly improving detection efficiency; Infrared sensitivity is higher, and it can still produce clear images in low light, cloudy and other environments without the need to build a darkroom, achieving all-weather outdoor detection and breaking the dependence of traditional equipment on dark environments.

AI intelligent recognition and wireless interconnection simplify operations and improve efficiency. The device is equipped with self-developed AI App intelligent detection software, compatible with Android and IOS systems, supports WIFI wireless operation, image transmission and data download, and does not require complicated wiring. One person can complete the entire process of device setup, parameter setting, detection and shooting, and data analysis. AI algorithms can automatically identify defect types, mark defect locations, count defect quantities, and generate standardized detection reports. Compared with manual visual interpretation, the efficiency is improved by more than 80%, and human errors are avoided. The detection results are more objective and accurate. At the same time, the software supports historical data storage, comparative analysis, and cloud backup, making it convenient for the operation and maintenance team to trace changes in component quality, providing accurate basis for component maintenance and replacement, and assisting in the refined operation and maintenance of photovoltaic power plants.

Extremely portable and durable, suitable for outdoor inspection in all scenarios. The LXG50 adopts a lightweight design, with a total weight of only 6.5kg (including camera, power supply, tripod), and a customized shock-absorbing protective box. It can be easily carried by a single person to various photovoltaic power plant sites such as mountains, roofs, and water surfaces, solving the problems of cumbersome equipment handling and poor outdoor adaptability of traditional equipment. The equipment casing is made of high-strength engineering materials, with a seismic, dustproof, and waterproof rating of IP64, suitable for outdoor extreme temperature environments ranging from -20 ℃ to 50 ℃. It is resistant to wind, sand, and corrosion, and can operate stably under harsh working conditions, extending the service life of the equipment. Equipped with a portable detection power supply, it has a compact size and long-lasting battery life. When fully charged, it can continuously detect more than 200 components, meeting the needs of large-scale power station inspections.

Flexible adaptation and wide application, covering the needs of the entire photovoltaic industry chain. LXG50 is suitable for all scenarios of photovoltaic module production quality inspection, arrival acceptance, pre grid connection testing of power plants, regular operation and maintenance of operating power plants, fault diagnosis, module scrap evaluation, etc. It is compatible with various types of photovoltaic modules such as monocrystalline, polycrystalline, PERC, TOPCon, HJT, and is suitable for testing large-sized modules such as 182mm and 210mm. Whether it is distributed household photovoltaics, industrial and commercial rooftop photovoltaics, or centralized large-scale ground power stations, LXG50 can be quickly deployed and accurately tested, providing reliable guarantee for component quality control. At present, the device has been put into use in multiple large photovoltaic power plants and module production enterprises in China, and has gained widespread recognition and praise from users for its excellent performance and stable performance.

Suzhou LAILX has been deeply involved in the field of photovoltaic testing for many years, always adhering to the concept of "technological innovation, quality-oriented, and service-oriented". The launch of the LXG50 portable EL detector is a major breakthrough for the company in the field of EL testing technology. In the future, LAILX will continue to increase research and development investment, continuously optimize product performance, enhance product intelligence level, and improve after-sales service system to provide users with comprehensive technical support and services, helping the photovoltaic industry improve quality and efficiency, promote healthy development, and contribute photovoltaic testing strength to achieve the "dual carbon" goal.
