In the wave of rapid development of the global new energy industry, photovoltaics, as the core pillar of clean energy, have become a key link in ensuring efficient operation of power plants and improving power generation revenue through precise detection and quality control of their component performance. With the continuous iteration of photovoltaic technology, 1500V high-voltage systems and high-power components have gradually become mainstream in the market. Traditional IV testers with 1000V/20A specifications are unable to meet the core requirements of power plant acceptance, operation and maintenance, and third-party testing due to insufficient range, low efficiency, and poor portability. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of photovoltaic testing for more than ten years. With profound technical accumulation, continuous innovative research and development, and rich industry practice, it has launched the LX-PV31 portable IV tester, which redefines the portable IV testing standards with its core advantages of precision, efficiency, portability, and safety, injecting strong momentum into the high-quality development of the photovoltaic industry.

As a standard IV curve tester for Lexus photovoltaic modules, LX-PV31 accurately targets industry pain points and achieves multiple breakthrough upgrades in core performance. In response to the current trend of popularity of 1500V high-voltage photovoltaic systems, this equipment will upgrade its testing range to 1500V/30A, perfectly adapting to mainstream high-power component and string testing needs, completely solving the problem of insufficient range and inability to adapt to high current testing of half piece components in traditional equipment. In terms of detection accuracy, LX-PV31 is equipped with a high-precision capacitive resistive load module, with a voltage measurement accuracy of up to ± 0.1V and a current measurement accuracy of up to ± 0.001A. The testing accuracy is controlled within the range of ± 0.5% ± 0.2V, which can accurately capture the subtle fluctuations in the power generation performance of the components and truly reproduce the IV curve characteristics, providing reliable data support for component efficiency evaluation and fault location.

Efficient detection is one of the core competencies of LX-PV31. The equipment adopts integrated packaging technology and high-speed scanning algorithm, and the IV curve detection of a single component or string can be completed in just 10 seconds, which is more than 50% more efficient than traditional equipment and greatly shortens the inspection and acceptance cycle of power plants. At the same time, LX-PV31 integrates a synchronous monitoring module for irradiance and temperature, which can real-time collect environmental parameters and automatically complete STC standard condition conversion, accurately calculate the current power generation efficiency and conversion rate of components, effectively eliminate the interference of environmental factors on test results, and ensure data accuracy and comparability. The device is equipped with a high brightness color touch screen visible under sunlight, with a bilingual operation interface in Chinese and English. The functional layout is clear and intuitive, supporting one click start detection, automatic data storage, and fast report export. Even non professionals can quickly get started and operate it, reducing the threshold for use.

The portability and safety design make the LX-PV31 easily adaptable to all outdoor work needs. The whole machine adopts a lightweight structural design, matched with a high-strength protective shell, which is earthquake resistant, drop resistant, dustproof and waterproof, and can adapt to complex outdoor environments such as mountains, deserts, high temperatures and humidity. The device is equipped with a high-capacity lithium-ion battery with a battery life of up to 8 hours, which meets the needs of all day outdoor testing and does not require frequent external power supply. At the same time, equipped with a 100 meter wireless communication module, it supports remote data transmission and device control, and operation and maintenance personnel can operate far away from high-voltage testing areas to avoid the risk of electric shock. In addition, LX-PV31 is equipped with multiple safety protection mechanisms such as high voltage isolation, overvoltage and overcurrent protection, and reverse connection protection, ensuring comprehensive operation safety from hardware to software, making detection work worry free.

Thanks to its outstanding performance, LX-PV31 has been widely used in various scenarios such as photovoltaic power plant construction acceptance, daily operation and maintenance, component production quality inspection, third-party testing and certification. In the acceptance stage of the power station, it is possible to quickly complete the performance survey of all power station components and strings, and accurately screen for inefficient and faulty components; During the operation and maintenance phase, regular IV curve testing is conducted to promptly identify issues such as hidden cracks, hot spots, aging, and mismatches in components, providing data support for operation and maintenance decisions and ensuring the long-term efficient operation of the power station; At the component production end, it can be used for production line sampling to strictly control product quality and reduce defect rates. At present, LX-PV31 has been highly recognized by numerous power plant owners, operation and maintenance enterprises, and testing institutions. Its market covers multiple provinces across the country and is exported to many countries and regions overseas.

Suzhou LAILX always adheres to the development concept of "technological innovation, quality first, customer-oriented", deeply cultivates the research and development and production of photovoltaic testing equipment, and has established a good industry reputation with excellent product quality, leading technical strength, and perfect after-sales service system.
