During the production, transportation, installation, and long-term operation of photovoltaic modules, internal defects such as hidden cracks, broken grids, virtual soldering, and PID decay are prone to occur. These "hidden dangers" not only lead to a decrease in power generation efficiency and accelerated power decay of the modules, but also may cause safety issues such as hot spots and short circuits, seriously threatening the overall revenue and operational safety of the power station. To accurately solve the problem of internal defect detection in photovoltaic modules, Suzhou LAILX has launched a new portable EL detector LXG30. With the core advantages of high-definition imaging, intelligent detection, and portability, it creates a "golden eye" for internal quality inspection of photovoltaic modules and comprehensively safeguards the quality of power plants.

The LXG30 portable EL detector is developed based on the principle of electroluminescence (EL). By applying a forward bias current to the photovoltaic module, the battery cell is excited to emit near-infrared light. The high-sensitivity infrared camera is used to capture the luminescence image, intuitively presenting the internal structure and defect status of the module. Compared to traditional detection methods that can only detect surface issues, LXG30 can penetrate the surface of components and accurately identify dozens of internal defects such as hidden cracks, broken grids, fragments, broken pieces, virtual welding, sintered mesh patterns, black cores, black edges, edge overengraving, PID attenuation, hot spot hazards, mixing, and low efficiency chips, achieving "no dead corners" quality inspection and preventing inferior components from flowing into power plants from the source, avoiding huge economic losses caused by component defects in the later stage.

Imaging performance is the core competitiveness of EL detectors. The LXG30 is equipped with a 20 megapixel high-sensitivity infrared camera and professional optical lens, which has ultra-high resolution and ultra strong sensitivity. Even extremely subtle hidden cracks and tiny broken grids can be imaged clearly, with rich image details, high contrast, and clear defects at a glance. The device adopts LAILX patented fully automatic focusing technology, which does not require manual adjustment.

During the detection process, it automatically focuses accurately, completely solving the pain points of difficult focusing and blurry imaging in traditional EL devices, greatly improving detection efficiency and imaging quality. At the same time, equipped with a military grade anti infrared darkroom, it can effectively block external natural light interference, support all-weather detection during day and night, and is not limited by time or environment, truly achieving efficient detection anytime, anywhere.
LXG30 is designed with ultimate portability to meet the practical needs of on-site inspection of photovoltaic power plants. The whole machine adopts a modular structure, consisting of an infrared camera, an intelligent control tablet, a portable EL power supply, a tripod, a waterproof box, etc. It is easy to disassemble and carry, and a single person can complete the entire process of assembly, testing, and storage. The device is equipped with a large capacity lithium battery power supply system, which does not require external mains power and can be used on site. It supports 24-hour ultra long battery life and meets the needs of large-scale power station inspection and patrol. The detection process supports WIFI wireless remote control, allowing for camera shooting and power on/off control through a tablet or laptop. Operators can stay away from the components to avoid the risk of high voltage electric shock, making the detection safer and more flexible.

In terms of intelligent functions, LXG30 is equipped with professional EL defect analysis software, which has AI intelligent defect recognition, automatic labeling, classification and statistics functions. It can automatically identify defect types and locate defect locations without the need for manual analysis, greatly improving detection efficiency and accuracy. The software supports image storage, comparison, and export, and can automatically generate standardized inspection reports, including component information, inspection images, defect details, quality judgment, and other content, providing data support for component quality assessment, responsibility definition, and operation and maintenance decision-making. At the same time, the device supports barcode/QR code scanning, achieving one-to-one binding of component information and detection data, facilitating digital management and data traceability of the power station. In addition, LXG30 supports synchronous detection of single and multiple components, with a maximum detection capacity of 25 components at once. The detection efficiency far exceeds that of similar products, and it is suitable for full scenario applications such as component factory quality inspection, power plant entry acceptance, regular operation and maintenance, and fault troubleshooting.

In terms of quality and service, LXG30 strictly adheres to international quality standards, using high-quality components and exquisite craftsmanship to manufacture. The equipment has strong stability and durability, and can adapt to a wide temperature range of -20 ℃~50 ℃. It has excellent dust, water, and shock resistance, meeting the long-term use needs of complex outdoor working conditions. As a professional brand in the field of photovoltaic testing, LAILX provides comprehensive technical training, after-sales maintenance, and upgrade services to ensure that users can use it with peace of mind.

In the current situation where the investment cost of photovoltaic power plants continues to rise and the industry's requirements for component quality are increasingly stringent, the LAILX LXG30 portable EL detector has become the preferred equipment for detecting internal defects in photovoltaic modules with its excellent performance of precise imaging, intelligent detection, portability, high efficiency, safety and reliability. It not only builds a solid defense line for component quality control, but also provides a solid guarantee for the long-term stable power generation of the power station and the maximization of investment returns. In the future, LAILX will continue to deepen its innovation in photovoltaic detection technology, launch more high-quality products, and help promote the high-quality development of the global photovoltaic industry.
