In the full lifecycle operation of photovoltaic power plants, hidden defects such as internal cracks, broken grids, virtual soldering, and black core chips are like "invisible killers". Although they are invisible to the naked eye, they can cause a sudden drop in power generation efficiency, accelerate aging, and even trigger safety hazards such as hot spots and fires, seriously threatening the investment return and long-term stable operation of the power plant. Traditional manual inspection is inefficient and has a high rate of missed detections. Large fixed EL detection equipment is bulky, complex to operate, and relies on darkroom environments, making it difficult to meet the large-scale and high-efficiency on-site inspection needs of outdoor power plants. To address industry pain points, Laix New Energy Technology Co., Ltd. (LAILX) in Suzhou has assembled a core R&D team and, after years of technical accumulation and field testing, has launched the LXG30 portable EL detector. With revolutionary advantages such as 24 million pixel ultra clear imaging, full dark light autofocus, outdoor strong light adaptation, and ultimate portability, it provides a one-stop non-destructive testing solution for photovoltaic module factory sampling, power plant operation and maintenance, and second-hand component screening, redefining the industry standard for portable EL testing.

The core competitiveness of the LXG30 portable EL detector lies in its precise defect recognition ability. It is equipped with an industrial grade high-resolution infrared CMOS detector, paired with professional infrared filter lenses and optimized optical path design. The imaging pixels far exceed those of similar portable devices in the industry, and can clearly capture infrared light with a wavelength of 900-1100nm. It can accurately identify fine hidden cracks, fine grid fractures, virtual soldering, black heart defects and other defects at the 0.1mm level. Even small defects in N-type high-efficiency components and ultra-thin silicon wafer components can be fully captured, completely eliminating defect detection and providing clear and intuitive image basis for component quality judgment. Based on the core principle of electroluminescence (EL), the device can excite the internal current of photovoltaic modules to generate weak luminescent signals. Through high-definition imaging technology, the internal structure of the modules can be visualized, which can not only accurately detect common defects, but also identify subtle problems such as edge damage of solar cells and misalignment of interconnect strips, fully covering the detection needs of internal defects in photovoltaic modules.

To overcome the technical challenge of outdoor strong light interference, the LXG30 is equipped with an intelligent light control adaptive system and a built-in high-sensitivity ambient light sensor that can monitor the on-site light intensity in real time. When the light exceeds 5000lux, the special light shield and shutter synchronization algorithm are automatically activated to block external light at the moment of shooting, ensuring that the weak electroluminescent signal of the component is accurately captured. Through actual testing, even in a strong noon light environment, its imaging clarity and detection accuracy are not affected, completely eliminating the dependence of traditional EL detection equipment on darkroom environments, achieving all-weather outdoor detection operations, and greatly improving the efficiency of power plant operation and maintenance. At the same time, the equipment adopts a modular integrated design, with light weight and small size. It is equipped with a dedicated three proof suitcase and portable backpack, which can be easily carried and quickly transported by a single person without the need for multiple people to cooperate in handling and setting up. It completely breaks the limitations of the site, whether it is distributed photovoltaic systems on rooftops, mountain and hilly power stations, large ground power stations, or household photovoltaic projects, testing operations can be carried out anytime and anywhere, truly realizing the concept of "testing on the go".

In terms of operational experience and durability, LXG30 fully balances professionalism and convenience. The device is equipped with a high-definition touch screen, and the operation interface is simple and friendly. It supports bilingual switching between Chinese and English, and can be quickly started without professional technical background. It can complete single component defect inspection in 30 seconds, and the daily detection volume can reach hundreds of pieces, greatly improving operation and maintenance efficiency. At the same time, the entire equipment is made of high-strength and wear-resistant engineering plastic material, with a protection level of IP65. It has waterproof, dustproof, and anti drop characteristics, and can adapt to various extreme working environments such as deserts, high altitudes, humidity, and low temperatures. The working temperature range covers -20 ℃ to 50 ℃, with industry-leading stability and durability, effectively reducing equipment maintenance costs and extending service life. In addition, LXG30 supports real-time storage of detection images, historical record queries, image exports, and wireless transmission. It can be integrated with computer software for image analysis and report generation, providing complete data support for power plant operation and maintenance management, and helping photovoltaic power plants achieve refined and intelligent operation and maintenance.

With its core advantages of high-definition imaging, super portability, all-weather detection, and stability and durability, the LXG30 portable EL detector has become a "mobile health inspector" for photovoltaic power plant operation and maintenance since its launch. It is widely used in major photovoltaic power plants, component manufacturers, and third-party testing institutions around the world, and has received unanimous praise from the industry. In the future, LAILX in Suzhou will continue to focus on innovation in photovoltaic detection technology, continuously iterate and optimize products, empower the high-quality development of the photovoltaic industry with hard core technology, and safeguard the quality control of photovoltaic modules and the safe and efficient operation of power plants.
