As the core power generation unit of a power station, the quality and stability of photovoltaic modules directly determine the overall life cycle benefits of the power station. During the production, transportation, installation, and long-term operation and maintenance processes, components are prone to internal defects such as hidden cracks, broken grids, virtual soldering, PID attenuation, and hot spots. These "hidden hazards" are difficult to identify with the naked eye and are not easily detected in the early stages, but can continue to cause a decrease in power generation efficiency, accelerated power attenuation, and in severe cases, lead to safety accidents such as short circuits and fires, causing huge economic losses to the power station. Traditional detection methods such as visual observation and multimeter measurement have drawbacks such as low detection accuracy, slow efficiency, and inability to visualize, making it difficult to meet the precise inspection needs of photovoltaic module defects. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of internal defect detection in photovoltaic modules and innovatively develops the LXG30 portable EL detector. With high-definition imaging technology, portable design, and intelligent operation, it achieves accurate, fast, and visual detection of internal defects in photovoltaic modules, providing core technical support for quality control, operation and maintenance of photovoltaic power plants, and becoming a recognized benchmark equipment for defect detection in the photovoltaic industry.

The LXG30 portable EL detector is based on the principle of electroluminescence (EL) detection. By applying a specific current to photovoltaic modules, it excites the solar cells to emit infrared light. Using a high-resolution infrared camera, it captures infrared images and clearly presents small defects such as hidden cracks, broken grids, virtual welding, low efficiency chips, mixed gears, and fragments inside the components. The detection accuracy can reach the micrometer level, completely solving the problem of traditional detection methods being unable to identify small internal defects. The equipment is equipped with a self-developed 24.16 million level high-definition infrared camera, equipped with a patented infrared chip and infrared lens. The infrared sensory chip has an efficiency of up to 99.8%, and the imaging clarity and sharpness are industry-leading. Even hair level hidden cracks and small virtual welds can be clearly presented, providing reliable basis for accurate defect judgment. Compared to similar products, LXG30 has optimized its infrared imaging algorithm, effectively reducing ambient light interference, supporting all-weather detection during both day and night, without the need for strict darkroom environments, greatly improving the adaptability and operational efficiency of detection scenarios.

Portability and efficient design are the core advantages of LXG30, perfectly adapting to the outdoor mobile detection needs of photovoltaic power plants. The equipment adopts a lightweight integrated design, with components such as the host, infrared camera, programmable constant current power supply, tripod, etc. made of lightweight and high-strength materials. The entire equipment is lightweight and comes with a three proof trolley case, which is dustproof, waterproof, and shockproof, making it easy to carry to various complex photovoltaic power plant scenarios such as mountains, deserts, roofs, and water surfaces. A single person can easily complete equipment transportation, deployment, and operation. Equipped with a 2-meter carbon fiber tripod, it is lightweight, high-strength, and supports multi angle adjustment. It can quickly fix the infrared camera in front of the photovoltaic module, achieving all-round and blind spot detection of the front and back of the module without disassembling the module, greatly reducing the workload of operation and maintenance, and reducing the risk of secondary damage to the module.

In terms of operational experience and intelligent functions, LXG30 demonstrates humanization and professionalism, significantly reducing operational barriers and improving detection efficiency. The device supports wireless control of tablet computers, enabling remote control, real-time image transmission, parameter settings, data storage, and other functions through a dedicated APP. Operators can complete detection operations without close contact with components, making it particularly suitable for high-altitude, high-pressure and other dangerous scene detection operations. The APP interface is simple and intuitive, and the operation process is simplified. Even non professionals can quickly get started after simple training, effectively reducing labor costs. The detection image can be previewed, zoomed in, and the defect location can be marked in real time. It supports one click saving, and the image format is compatible with commonly used formats, making it convenient for subsequent archiving, analysis, and report generation. At the same time, by integrating with the Laikesi Photovoltaic Cloud Platform, detection data can be directly uploaded to the cloud, enabling cloud storage, remote viewing, AI defect intelligent recognition, power plant modeling and analysis, and other functions, helping users achieve intelligent management of detection data and precise operation and maintenance decision-making.

The LXG30 is equipped with a programmable two in one detection power supply, supporting wide voltage output and adapting to the full specifications of 60V-1500V photovoltaic modules and string detection requirements. It can synchronously complete EL detection of single or multiple modules. The power supply adopts imported high-performance lithium batteries with strong endurance. When fully charged, it can support continuous testing of more than 500 components, meeting the batch testing needs of large-scale power plants. Equipped with multiple safety protection functions such as overvoltage, overcurrent, reverse connection, and overheating, the detection process is safe and reliable, effectively ensuring the safety of equipment and components. In addition, the device supports the string EL detection mode, which can directly detect the entire string components without dismantling them one by one, greatly improving the efficiency of string level defect detection and adapting to the scenarios of pre grid acceptance and batch inspection during operation and maintenance of power plants.

With excellent performance and reliable quality, the LXG30 portable EL detector has been widely used in the entire life cycle scenarios of photovoltaic module factory quality inspection, power station arrival acceptance, grid connection inspection after installation, regular inspection during operation and maintenance, and troubleshooting of faulty components. At the component production end, it can be used for component defect screening on the production line to prevent unqualified products from leaving the factory; At the construction end of the power station, it is possible to detect component hidden cracks and damages caused during transportation and installation, ensuring the quality of power station construction; On the operation and maintenance end, internal defects of components can be regularly inspected to promptly detect hidden dangers such as hot spots and hidden cracks, avoiding the expansion of defects that may lead to power generation losses and safety accidents.
