In the wave of global photovoltaic industry moving towards high efficiency and high power, precise detection of the power generation performance of photovoltaic modules and strings is the core link to ensure the power generation efficiency of power plants, control operation and maintenance costs, and evaluate asset value. Traditional IV testers suffer from pain points such as insufficient range, poor compatibility with dual glass components, and weak portability, making it difficult to meet the testing needs of current 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 profound technical accumulation and continuous innovation capabilities, it has launched the LX-PV33 portable IV tester, which redefines the photovoltaic IV testing standards with a 2000V/40A ultra large range, dual glass module exclusive testing algorithm, and lightweight portable design, providing efficient, accurate, and reliable testing solutions for the entire photovoltaic industry chain.

As the flagship photovoltaic performance testing equipment of LAILX, LX-PV33 has been focusing on the core pain points of the industry since its development, targeting the application bottlenecks of traditional equipment. In the current photovoltaic market, double glass modules have become the mainstream choice for power plants due to their high durability, long lifespan, and excellent environmental resistance. However, their double-sided power generation characteristics make it difficult for traditional IV testers to accurately separate positive and negative power generation data, resulting in large detection errors; At the same time, the popularity of high-power components and string connections has led to frequent range overflow problems in traditional equipment with a 1000V/20A range, making it impossible to complete complete complete testing. In response to these two core challenges, LX-PV33 has achieved a breakthrough technological upgrade by adopting a resistance based high-precision testing module developed by Lexus, expanding the testing range to 0-2000V and 0-40A, perfectly adapting to the needs of high-power components and long-distance string testing, and completely solving the pain point of insufficient range in the industry. In terms of double glass component detection, the equipment is equipped with a multi irradiation intelligent algorithm, which can accurately shield the interference of back panel power generation, independently calculate the power generation efficiency and STC conversion value of the front battery cells, and improve the accuracy by more than 30% compared to traditional equipment, achieving a leap from "fuzzy estimation" to "precise quantification" in double glass component detection.

In terms of performance accuracy and detection efficiency, LX-PV33 also demonstrates industry-leading strength. The equipment has a 10 second high-speed detection capability, and a single component or a whole string can quickly complete the IV curve drawing, open circuit voltage (Voc), short-circuit current (Isc), maximum power point (Pmax), fill factor (FF), conversion efficiency (η) and other key parameter measurements, greatly improving the efficiency of power station acceptance, operation and maintenance inspection, and fault troubleshooting. Built in high-precision capacitors and resistive loads, combined with intelligent data calibration algorithms, can effectively eliminate detection errors caused by environmental temperature and irradiance fluctuations, ensuring data stability and reliability. Whether in strong or weak light environments, it can output accurate detection results. At the same time, the device supports batch testing of multiple strings, which can quickly compare the differences in power generation performance between different strings, accurately screen abnormal strings, assist operation and maintenance personnel in optimizing MPPT parameters, improving inverter matching efficiency, and helping to increase the overall power generation of the power station.

Portable and intelligent design enables LX-PV33 to meet the needs of full field photovoltaic detection. The whole machine adopts integrated lightweight packaging technology, with a sturdy, durable and lightweight body. Paired with a dedicated portable case, it can be easily carried by a single person to various complex power plant scenarios such as mountains, rooftops, deserts, etc. The operation interface adopts high-definition touch color screen, supports bilingual switching between Chinese and English, has a simple and intuitive interface, and is equipped with a one click detection mode. Novices can quickly get started without professional training. The device is equipped with a large capacity storage, which can store more than 2000 sets of test data. It supports USB one click export and on-site printing. Paired with dedicated PC analysis software, it can achieve high-definition analysis of IV curves, automatic generation of data reports, and intelligent fault diagnosis, greatly reducing the cost of later data analysis and report preparation. In addition, LX-PV33 has wireless communication function, which can be wirelessly linked with radiation meters and temperature sensors to synchronize environmental data in real time, automatically complete STC standard condition correction, and further enhance the professionalism and authority of detection data.

With excellent performance and scene adaptation capabilities, LX-PV33 has been widely used in the entire industry chain, including photovoltaic module production quality inspection, power station completion acceptance, daily operation and maintenance inspection, and third-party testing agency evaluation. At the component production end, it is possible to accurately determine the efficiency of A-level boards, B-level board grades, and C-level board failures, helping enterprises strictly control the quality of factory products; At the power station operation and maintenance end, it is possible to quickly locate issues such as hidden cracks, hot spots, diode faults, and string mismatches in components, providing data support for operation and maintenance decisions; In the field of third-party testing, its accuracy and reliability have become industry benchmarks and have been recognized by numerous authoritative institutions.

Suzhou LAILX always adheres to the development concept of "technological innovation, quality first". The launch of LX-PV33 portable IV tester is not only a precise response to industry pain points, but also a concentrated display of its own technical strength. In the future, LAILX will continue to deeply cultivate the field of photovoltaic testing, guided by user needs, continuously iterate and upgrade product performance, launch more high-precision, intelligent, and portable testing equipment, and help the high-quality development of the global photovoltaic industry, contributing core strength to the clean energy industry.
