With the large-scale and high-voltage development of the new energy photovoltaic industry, 1500V high-voltage photovoltaic systems have been widely popularized, and high-power half cell modules and large capacity string components have become the mainstream of the industry. The pain points of traditional 1000V range IV testing equipment, such as insufficient range, low detection efficiency, and large data deviation, are becoming increasingly prominent, seriously restricting the precise implementation of photovoltaic power station acceptance, operation, and quality inspection work. In order to solve the industry's testing problems and deeply cultivate the field of new energy testing, Suzhou LAILX has launched the LX-PV31 portable IV tester based on years of technical accumulation and scene based research and development experience. With four core advantages of high voltage adaptation, fast detection, precise traceability, and portability and ease of use, it reconstructs a new standard for photovoltaic string and component performance testing, providing a professional and efficient integrated solution for quality control throughout the entire lifecycle of photovoltaics.

As a standard testing equipment suitable for current high-voltage photovoltaic systems, LX-PV31 completely breaks through the performance of traditional equipment. In terms of testing accuracy and efficiency, LX-PV31 achieves a balance between precision and efficiency. The device is equipped with high-precision acquisition chips, with a voltage measurement accuracy of ± 0.1% FS and a current measurement accuracy of ± 0.2% FS. It can accurately capture subtle fluctuations in the IV curve, accurately calculate more than ten core performance parameters such as open circuit voltage, short-circuit current, peak power, fill factor, and photoelectric conversion efficiency, and accurately locate various problems such as component attenuation, occlusion, hidden loss, and wiring faults, providing authoritative data support for component quality evaluation and fault diagnosis. At the same time, the equipment is equipped with a high-speed scanning algorithm, and the detection time for a single set of photovoltaic modules or string is only 10 seconds. It supports automatic continuous testing and custom testing intervals, and the batch detection efficiency is increased by more than 50% compared to traditional equipment, greatly reducing the inspection and acceptance period of power plants.
For complex outdoor work environments, LX-PV31 is equipped with an integrated environmental perception system, which includes high-precision irradiance meters and temperature sensors. It can synchronously collect peripheral parameters such as environmental irradiance, component temperature, and environmental temperature in real time, achieve synchronous recording and linked storage of test data and environmental parameters, completely avoid the interference of environmental factors on test data, ensure the authenticity, comparability, and accuracy of test data in different scenarios and time periods, and make photovoltaic performance testing free from environmental limitations, with more rigorous data traceability.

The portable and intelligent design significantly reduces the threshold for on-site operations. The equipment adopts a lightweight integrated packaging process, with a total weight controlled within 6kg. The body size is compact and small, and operation and maintenance personnel can easily carry and operate it with one hand, shuttling between complex photovoltaic arrays without the need for auxiliary handling equipment. It is perfectly suitable for work scenarios such as high-altitude roofs, steep mountain slopes, and water power stations where it is inconvenient to install large equipment. The device is equipped with a 6.5-inch high brightness color touch screen, which is clear and visible under strong light. It supports one click switching between Chinese and English, with a simple and intuitive operation interface and clear functional zoning. Novices can quickly get started without professional training and are suitable for various grassroots operation and maintenance personnel.

In terms of data management, LX-PV31 combines the advantages of large capacity storage and convenient export. The built-in memory of the body can store more than 2000 sets of complete test data and IV curve graphs, meeting the data retention needs of large-scale power plant batch testing. The device supports USB high-speed one click data export and is equipped with professional PC analysis software, which can achieve deep data analysis, curve comparison, automatic report generation, data cloud archiving and other functions, effectively simplifying the later data sorting, report preparation, quality review process, and helping photovoltaic enterprises achieve standardized and intelligent management of detection data.

Since its launch, the Suzhou LAILX LX-PV31 portable IV tester has been widely used in various scenarios such as photovoltaic power plant engineering acceptance, daily operation and maintenance, component factory quality inspection, and third-party authoritative testing, thanks to its stable performance, comprehensive adaptability, and ultra-high operating efficiency. It has become a core standard equipment for photovoltaic construction enterprises, operation and maintenance teams, and testing institutions. In the future, LAILX will continue to focus on the iteration of photovoltaic detection technology, deeply cultivate industry scene demands, and use hardcore technology to support the high-quality, high-efficiency, and standardized development of the photovoltaic industry.
