In the wave of rapid development of the global new energy industry, photovoltaics, as the core pillar of clean energy, precise detection and quality control of its component performance are key links to ensure efficient operation of power plants and improve power generation revenue. 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 generally suffer from pain points such as insufficient range, poor compatibility of double glass components, and weak portability, making it difficult to meet the current testing needs of high-power photovoltaic equipment. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of photovoltaic testing for many years. With its profound technical accumulation and innovative research and development capabilities, it has launched the LX-PV33 portable IV tester, which redefines the testing standards for photovoltaic modules with its three core advantages of "precise testing, versatile adaptation, and ultimate portability", providing a one-stop testing solution for the industry and promoting efficient upgrading in the photovoltaic testing field.

As a masterpiece created by LAILX focusing on the core requirements of on-site inspection of photovoltaic power plants, LX-PV33 has been anchored to the core goal of "breaking through limitations and adapting to rigid needs" since its development, comprehensively overcoming the technical bottlenecks and application pain points of traditional equipment. In terms of range design, the device accurately matches the current development trend of high voltage and high current in photovoltaic modules, supporting 2000V ultra large open circuit voltage and 40A strong short-circuit current testing, easily covering all types of photovoltaic modules and string testing on the market, including single crystal, polycrystalline, double glass, PERC, TOPCon, HJT, etc. Whether it is conventional modules or high-power high-efficiency modules, it can achieve precise measurement, completely solving the industry problem that small range devices cannot adapt to new modules. Especially in response to the market trend of the popularization of double glass components, LX-PV33 innovatively adopts a multi irradiation algorithm, which can effectively shield the influence of back panel electrical energy. It only calculates the power generation efficiency and STC conversion value of the front battery cells, perfectly adapting to the detection needs of double-sided double glass components and becoming a specialized tool for double glass component detection.

Accuracy is the core vitality of detection equipment, and LX-PV33 achieves comprehensive breakthroughs in performance, providing reliable data support for photovoltaic detection. The equipment adopts the latest resistance testing module from Lexus, paired with high-precision sampling chips. The current measurement accuracy reaches 0.001A, the voltage measurement accuracy reaches 0.1V, and the testing accuracy is as high as ± 0.5% ± 0.2V. The single component detection is more accurate and can truly restore the power generation performance of the components. At the same time, equipped with advanced capacitive electronic load technology, it achieves 10 second high-speed IV curve scanning, greatly improving on-site detection efficiency and meeting the needs of large-scale power plant batch detection. In addition, the device is equipped with a rich database of photovoltaic module correction models and supports STC nominal parameter conversion testing. It can automatically calculate the current power generation efficiency and conversion rate of the solar panel, matching over 95% of the current photovoltaic panel specifications without the need for manual parameter switching, making the operation more convenient.

At the design level, LX-PV33 deeply meets the requirements of outdoor inspection scenarios, balancing portability, durability, and ease of use. The whole machine adopts an integrated lightweight design, which is compact, lightweight and easy to carry. Paired with a high-strength protective box, it can be easily carried and transported by a single person, completely eliminating the limitations of laboratory space and power supply, and easily adapting to various complex outdoor scenes such as deserts, mountains, and coasts. The equipment adopts a high-voltage isolation design to ensure operational safety, and is equipped with a Chinese and English operation interface with clear functional instructions. It supports one click detection data export and is compatible with common formats such as Excel, making it easy to archive and analyze data. In addition, it supports component barcode scanning and environmental monitoring functions, equipped with a 100 meter wireless communication module, which can synchronously monitor environmental parameters such as irradiation and temperature, accurately calculate PR values, and provide comprehensive data support for power plant operation and maintenance.

With excellent performance and scene adaptation capabilities, LX-PV33 has been widely used in various scenarios such as photovoltaic module factory quality inspection, power station arrival acceptance, on-site installation and commissioning, daily operation and maintenance inspection, and third-party testing agency certification. At the component production end, it is possible to accurately screen for non-conforming products to ensure factory quality; At the operation and maintenance end of the power station, it is possible to quickly locate components with power attenuation, mismatch, and other issues, promptly troubleshoot faults, and improve the overall power generation efficiency of the power station; In the field of third-party testing, high-precision testing data can serve as an important basis for asset valuation and liability identification, helping to promote the standardized development of the photovoltaic industry.

As a leading enterprise in the field of domestic photovoltaic testing equipment, Suzhou LAILX always adheres to the development concept of "technological innovation, quality first", focuses on industry pain points, and continues to launch high-performance testing equipment. The heavyweight launch of the LX-PV33 portable IV tester is not only another important manifestation of LAILX's technological strength, but also will promote the upgrading of the photovoltaic detection industry towards precision, efficiency, and portability. In the future, LAILX will continue to deeply cultivate the field of photovoltaic testing, constantly break through technological bottlenecks, and contribute to the high-quality development of the global photovoltaic industry with better products and more comprehensive services, contributing to the clean energy industry.
