In recent years, the global photovoltaic industry has entered a fast lane of large-scale and efficient development, and the performance testing requirements for photovoltaic modules and power stations have become increasingly stringent. Traditional IV detection equipment commonly suffers from pain points such as limited range, cumbersome operation, and weak outdoor adaptability, making it difficult to meet the precise detection needs of 1500V high-voltage systems and high-power string systems. As a leading enterprise in the field of photovoltaic testing equipment in China, LAILX New Energy Technology Co., Ltd. (LAILX) has been deeply engaged in technology research and development for many years. With the core advantages of high precision, fast response, and strong portability, LAILX has launched the LX-PV31 portable IV tester, providing comprehensive solutions for photovoltaic module production quality inspection, on-site acceptance of power plants, daily operation and maintenance, and third-party testing, redefining the new benchmark for portable IV testing.

LX-PV31 is a standard photovoltaic module IV curve tester under the Lexus brand, with core performance benchmarking against international first-class standards, specially designed to solve the problem of insufficient testing range in mainstream markets. The maximum test voltage of the equipment reaches 1500V, and the test current is expanded to 30A, perfectly covering the mainstream 1000V and 1500V photovoltaic systems in the current market. It can accurately detect the power generation efficiency, conversion rate, and various electrical performance parameters of individual components and strings, especially suitable for the detection needs of half piece components and high-power components, completely bidding farewell to the dilemma of limited 20A range of traditional equipment. It adopts dynamic capacitor charging testing technology, combined with high-precision capacitive/resistive loads, with a voltage measurement accuracy of 0.1V and a current measurement accuracy of 0.001A. The testing accuracy is controlled within ± 0.5%, which can truly reproduce the I-V and P-V curve characteristics of photovoltaic modules under natural light, accurately obtain core data such as short-circuit current, open circuit voltage, peak power, fill factor, series resistance, etc., and provide reliable basis for component quality grading and power station performance evaluation.

Efficiency and convenience are another core highlight of LX-PV31. The equipment adopts an integrated military grade packaging design, with a compact and sturdy structure and a size of only 390300200mm. The whole machine is lightweight and can be easily carried by a single person with a dedicated protective box. It is suitable for outdoor power stations, high-altitude supports, laboratories and other multi scene testing. The operation interface adopts a bilingual design in Chinese and English, with clear and easy to understand functional identification. It is equipped with a high brightness color touch screen visible under sunlight and a dual operation mode of physical buttons. Data reading is clear in a strong light environment, and non professionals can quickly get started. The detection process is highly intelligent, and single component or string detection can be completed in just 10 seconds. It supports one click data export and has a built-in large capacity memory that can store over 2000 test waveforms. It is also equipped with an SD card slot for unlimited storage space expansion. The host, irradiance meter, and temperature probe are designed with a 100 meter wireless connection, breaking free from traditional wired constraints. Testing personnel can operate remotely, greatly improving the safety and flexibility of high-altitude and large-area power station testing.

In addition, LX-PV31 is equipped with powerful intelligent analysis functions, with over 95% of mainstream photovoltaic panel specification data built-in. It supports one click import, eliminating the need for manual parameter settings and effectively reducing the tedious process of switching and detecting components of different specifications. The equipment has a professional STC nominal parameter conversion function, which can automatically convert on-site test data into parameter values under standard testing conditions, eliminate the influence of environmental temperature and irradiance changes on the detection results, and ensure accurate data comparison. Equipped with exclusive IV curve analysis software, it can achieve real-time data transmission, high-definition curve analysis, and automatic report generation. It supports component barcode scanning and recognition, intelligently binds detection data with component information, and facilitates data traceability and management. LX-PV31 covers the entire process from component production and factory quality inspection, to power station construction acceptance, and later operation and maintenance performance investigation. It effectively helps enterprises control product quality, quickly locate component mismatches, hidden cracks, aging and other issues, reduce power station operation and maintenance costs, and improve power generation revenue.

As a national high-tech enterprise, Suzhou LAILX has always adhered to independent innovation and promoted the upgrading of the photovoltaic testing industry through technological breakthroughs. The LX-PV31 portable IV tester embodies the company's years of research and development efforts. From selecting core components to polishing the entire machine process, it has undergone rigorous testing and verification, and has good high and low temperature adaptability, anti-interference and stability. It can operate stably in outdoor environments ranging from -10 ℃ to 50 ℃. At present, this product has been widely used in State Grid, five major power generation groups, well-known photovoltaic module manufacturers, and third-party testing institutions, and has gained high market recognition for its excellent performance and reliable quality.

In the future, as the photovoltaic industry develops towards high voltage, high power, and large-scale, precise and efficient detection equipment will become an important support for industrial development. Suzhou LAILX will continue to be guided by market demand and driven by technological innovation, continuously optimizing and upgrading core products such as LX-PV31. At the same time, more testing equipment suitable for industry development will be launched to safeguard the high-quality development of the global photovoltaic industry and help steadily promote the "dual carbon" goal.
