As the core component of power generation in power plants, photovoltaic modules have microscopic defects such as hidden cracks, broken grids, virtual soldering, and PID decay, which are the core causes of the declining power generation efficiency, frequent hot spot faults, and shortened service life of power plants year by year. These hidden defects cannot be identified by naked eye or conventional detection methods, and their long-term existence can cause local overheating of components, sudden power drops, and even lead to safety accidents such as component burnout and system short circuits, causing huge economic losses to the power plant. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of internal defect detection in photovoltaic modules, and relies on core infrared imaging technology and years of industry experience to launch the LXG50 portable EL detector. This product has core advantages such as 30 million pixel industrial grade infrared imaging, wireless intelligent control, full scene adaptation detection, and AI intelligent recognition analysis, accurately capturing micro level hidden defects, providing professional and efficient solutions for photovoltaic module quality control, power station operation and maintenance testing, and fault tracing analysis, and building a solid defense line for photovoltaic power station quality and safety.

The core competitiveness of LXG50 portable EL detector lies in its ultimate imaging performance, which can accurately identify various small hidden defects. The device is equipped with a full frame industrial grade CMOS infrared chip, paired with a self-developed 99.8% high infrared sensory chip and a 17mm wide-angle infrared lens, to achieve 30 million pixel high-definition imaging with an imaging accuracy of>0.2mm/pixel. It can clearly detect fine cracks with a width of less than 0.2 μ m, and easily capture more than ten types of internal defects such as hidden cracks, broken grids, fragments, virtual soldering, sintering, PID attenuation, etc. It performs outstandingly in N-type half chip components and high-efficiency component detection, with a defect recognition rate increased by more than 40% compared to traditional equipment. Different from the limitations of traditional EL detectors that require dark environment detection, the LXG50 is equipped with a patented daytime detection module and uses high-sensitivity imaging technology to directly detect in natural light environments without the need to build a shading shed, greatly simplifying the detection process and improving outdoor work efficiency, truly achieving "day and night, anytime and anywhere" rapid detection.

The portable design and rapid deployment capability enable the LXG50 to perfectly adapt to various complex photovoltaic detection scenarios. The whole machine adopts a lightweight integrated design, with integrated packaging of core components. The total weight of the equipment is only 4.2kg, and it is equipped with a high-strength aluminum alloy portable case, which can be easily placed in the trunk of the vehicle. It can be carried by a single person to various photovoltaic power plant sites such as mountains, water surfaces, roofs, deserts, etc., completely solving the problems of difficult transportation and limited space of traditional large EL detectors. The device adopts a modular assembly design, which does not require professional tools and can quickly build the camera, bracket, and power supply in 3 minutes; Equipped with an adjustable tripod to meet the detection needs of components at different heights, the bracket has strong stability and outstanding wind resistance, and can also stably image in complex outdoor environments. At the same time, LXG50 adopts a wireless control design and supports WIFI wireless connection. It can achieve remote camera control, parameter adjustment, real-time image transmission and download through a mobile phone or tablet APP, without the need for close range operation, which not only improves the convenience of operation but also ensures the safety of personnel during high-voltage detection process.

The intelligent control system and AI defect recognition function significantly reduce the operating threshold and improve the efficiency of detection and analysis. The LXG50 is equipped with a full-time low light autofocus system, which does not require manual focusing or distance measurement. The device can automatically recognize the position of components, quickly and accurately focus, ensuring that every image is clear and without blur. Even beginners can easily obtain high-quality inspection images. Equipped with a dedicated EL detection app, the interface is simple and intuitive, supporting bilingual switching between Chinese and English. It integrates full process functions such as image capture, real-time preview, defect annotation, data storage, and report generation, making it easy to operate and learn. The core AI intelligent recognition module can automatically identify common defects such as hidden cracks, broken grids, and virtual welding, accurately mark the location, type, and size of defects, without the need for manual analysis of images one by one, greatly reducing manual workload, avoiding human omissions and misjudgments, and improving detection and analysis efficiency by more than 60%. At the same time, the device supports multi component synchronous imaging, which can complete 1-2 component inspections at once, with imaging speeds as fast as 3-10 seconds per image, suitable for large-scale power plant batch inspection needs.

Professional level testing power supply and multiple safety protections ensure stable and reliable testing process. The LXG50 is equipped with a programmable 2-in-1 detection power supply, built-in high-performance lithium battery, with a battery life of up to 8 hours, meeting all day outdoor detection needs; The power supply supports wireless control and can directly adjust the output current and voltage through the APP, adapting to the detection needs of different types of components. It supports high and low current switching and balances the detection of both conventional and subtle defects. At the same time, the power supply has overvoltage, overcurrent, short circuit, and reverse connection protection functions, effectively avoiding component damage and safety accidents caused by operational errors or equipment failures during the detection process. The equipment adopts industrial grade protection design, with a dust-proof, waterproof, and impact resistant shell. It can operate stably in a temperature environment of -10 ℃ to 50 ℃ and adapt to complex weather conditions such as strong outdoor light, rainy weather, and sand and dust, ensuring continuous testing work.

A comprehensive data management and traceability system that meets the quality control needs of the entire lifecycle of photovoltaics. The LXG50 has clear detection images and obvious defect features. It supports local image storage and cloud upload. The body can store more than 5000 sets of detection images, and the cloud can achieve permanent data storage for subsequent traceability queries and comparative analysis. The APP supports one click generation of detection reports, which include complete content such as component information, detection time, environmental parameters, defect images, defect analysis, etc. The format is standardized and can be directly used for power plant acceptance, operation and maintenance records, quality accountability, and other scenarios. Whether it is the factory quality inspection of photovoltaic module manufacturers, the arrival sampling and installation acceptance during the power station construction stage, or the regular operation and maintenance testing and troubleshooting of faulty components during the operation stage, LXG50 can meet the requirements of full scene testing with precision, efficiency, and convenience.
