In the current rapid iteration of the global photovoltaic industry towards high voltage and high power, the performance testing of photovoltaic modules and power plants is facing higher requirements. Traditional IV testing equipment commonly suffers from pain points such as insufficient range, cumbersome operation, and poor outdoor adaptability, making it difficult to meet the testing needs of 1500V high-voltage systems and large-sized components. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of photovoltaic testing for many years. With profound technical accumulation and industry insights, it has launched the LX-PV31 portable IV tester, which redefines the portable IV testing standards with the core advantages of precise testing, efficient operation, and portable design, providing a one-stop efficient solution for photovoltaic module production quality inspection, power station operation and maintenance, and third-party testing.

As a LAILX standard photovoltaic module IV curve testing equipment, LX-PV31 has achieved a breakthrough upgrade in core performance, accurately solving the industry's core pain points. The current mainstream equipment in the photovoltaic market has a range of 1000V/20A. When facing 1500V high-voltage string and half piece, large-sized high-power components, there are frequent problems of insufficient range and inaccurate testing. LX-PV31 is targeted for expansion, with a maximum test voltage of up to 1500V and a maximum test current of 30A, fully covering the testing needs of mainstream 1500V photovoltaic systems and various high-power components. It perfectly adapts to the measurement of working current of about 20A for half chip components, completely solving the problem of limited range of traditional equipment.

In terms of detection accuracy and efficiency, LX-PV31 has the dual advantages of high precision and fast response. The equipment adopts self-developed high-precision capacitive/resistive loads, combined with professional level radiometer operation modules. The voltage measurement accuracy reaches * * ± 0.1V * *, the current measurement accuracy reaches * * ± 0.001A * *, and the testing accuracy is controlled within the range of * * ± 0.5% ± 0.2V. It can accurately capture the subtle changes in component power generation efficiency, conversion rate, and IV curve, providing authoritative data support for component level determination and power station performance evaluation. At the same time, the equipment is equipped with high-speed scanning technology, and single component or string detection can be completed in just 10 seconds, which is more than 50% more efficient than traditional equipment and greatly reduces outdoor detection operation time. It is particularly suitable for batch operation and maintenance testing of large-scale photovoltaic power plants.

Portable and intelligent design make outdoor complex scene operations easier and more efficient. The LX-PV31 adopts integrated packaging technology, with a compact and sturdy body structure that balances earthquake resistance, dust prevention, and moisture resistance. It is suitable for various harsh outdoor environments such as mountains, deserts, and coastal areas. The whole machine is equipped with a high-capacity lithium-ion battery, which can meet the needs of all day outdoor operations and break free from power constraints; Paired with a high brightness color touch screen visible under sunlight, it supports dual operation of touch screen and keyboard. The Chinese and English operation interface is simple and intuitive, and the functional instructions are clear and easy to understand. Novices can quickly get started without complex training. In addition, the device is equipped with rich peripheral interfaces, supporting one click detection data export, component barcode scanning, 100 meter wireless communication and other functions. It can synchronously monitor irradiance and ambient temperature, automatically calculate power generation and PR value, and be paired with dedicated IV curve analysis software to high-definition analyze IV curves and generate standardized detection reports, achieving the full process intelligence of "detection analysis archiving".

With outstanding performance, LX-PV31 has been widely used in multiple core links of the photovoltaic industry chain. At the component production end, it can be used for high-precision efficiency testing of A-grade boards, grading of B-grade board components, and performance screening of C-grade boards, helping production enterprises strictly control product quality; Suitable for 1500V high-voltage string testing, power station acceptance testing, daily operation and maintenance inspections in power station construction and operation, quickly identifying issues such as abnormal power generation efficiency and component aging; In the field of third-party testing institutions, with accurate and reliable testing data, it has become the preferred configuration for photovoltaic module certification and power plant quality assessment.

Suzhou LAILX always adheres to the development concept of "technological innovation, quality first". The launch of LX-PV31 portable IV tester is another important achievement of the company's deep cultivation of photovoltaic detection technology. In the future, LAILX will continue to focus on industry pain points, increase research and development investment, launch more high-performance and high reliability testing equipment, help promote the high-quality development of the global photovoltaic industry, and contribute more to the clean energy industry.
