As a LAILX standard photovoltaic module IV curve testing equipment, LX-PV31 achieves multiple breakthroughs in core performance and accurately matches the testing requirements of high-voltage photovoltaic systems. The device supports 1500V DC photovoltaic string system testing, with a maximum testing current of 30A, covering a power range of 50W to 30kW, perfectly adapting to the testing needs of current mainstream 1500V high-voltage string and various specifications of components, completely solving the limitation of traditional equipment's 1000V range upper limit. In terms of measurement accuracy, LX-PV31 is equipped with a self-developed high-precision testing module, with a voltage measurement accuracy of 0.1V, a current measurement accuracy as low as 0.001A, and a power testing accuracy of better than ± 0.5% ± 0.2V. It can accurately capture the I-V curve and P-V curve of photovoltaic modules, synchronously measure more than ten key parameters such as short-circuit current, open circuit voltage, peak power, fill factor, conversion efficiency, etc., and provide accurate data support for photovoltaic module performance evaluation.

The complexity of outdoor detection scenarios imposes strict requirements on device portability and environmental adaptability. LX-PV31, based on users' actual operational needs, creates an ultimate experience of lightweight and anti-interference. The whole machine adopts an integrated packaging design, with a compact body and a light weight of up to 3.5kg. Paired with a dedicated portable case, it can be easily carried by a single person to various complex work scenarios such as mountains, hills, roofs, etc., completely eliminating the troubles of traditional large testing equipment handling and limited space. The equipment adopts industrial grade protection design, and the shell has dust-proof, waterproof, and anti vibration characteristics. It can operate stably in extreme temperature environments ranging from -20 ℃ to 60 ℃, adapt to complex weather conditions such as outdoor strong light, rain, sand and dust, and ensure uninterrupted testing work 24/7. At the same time, the host and detection probe are connected wirelessly, with a maximum transmission distance of 100 meters. This not only avoids safety hazards caused by cable entanglement during high-voltage detection, but also allows operators to stay away from high-voltage components, greatly improving operational safety, especially suitable for rapid inspection of large-area photovoltaic arrays.

Intelligent operation and comprehensive data management are the core advantages of LX-PV31 in improving detection efficiency and simplifying operation and maintenance processes. The device is equipped with a 3.5-inch high brightness touch color screen, which is clear and visible under sunlight. It supports bilingual operation interfaces in Chinese and English, with a simple and intuitive functional layout. Novices can quickly get started without professional training. Built in rich database of photovoltaic module parameters, covering mainstream manufacturers' module specifications at home and abroad, supporting one click parameter matching, without the need for manual tedious settings; Equipped with barcode scanning function, it can quickly identify component information, achieve precise binding between detection data and components, and facilitate subsequent traceability management. In terms of detection efficiency, LX-PV31 achieves fast detection of single components or strings in 10 seconds, supports automatic continuous testing, customizable testing intervals, and batch completion of multiple component detection. The efficiency of a single inspection is increased by more than 50% compared to traditional equipment. Convenient data storage and export, the built-in memory of the body can store more than 2000 sets of test data, supports USB one click export, and is matched with professional analysis software on the PC side. It can achieve functions such as deep data analysis, curve generation, and report printing, meeting the needs of multi scenario data management such as power plant operation and maintenance, third-party testing, and quality acceptance.

The power generation efficiency of photovoltaic modules is closely related to environmental factors. LX-PV31 comes standard with high-precision environmental detection probes to achieve comprehensive and accurate calibration of test data. The equipment is equipped with an irradiance meter, ambient temperature sensor, and component temperature sensor, which can monitor the irradiance, ambient temperature, and component temperature in real time during the testing process. The measured parameters are automatically corrected to standard test conditions (STC), eliminating the influence of environmental factors on the detection results, ensuring comparability of test data at different times and in different scenarios, and providing scientific basis for efficiency evaluation and fault diagnosis of photovoltaic power plants. Whether it is the completion acceptance of power plants, daily operation and maintenance inspections, component arrival sampling, or third-party quality evaluation, LX-PV31 can become a reliable tool in the field of photovoltaic testing with accurate, efficient, and convenient performance.

Relying on LAILX's technological accumulation and perfect service system in the field of photovoltaic testing, LX-PV31 strictly follows industry standards from research and development to production. After multiple rounds of rigorous testing and scenario verification, the stability and reliability of the product have been tested by the market. The company always adheres to the concept of "technological innovation and service-oriented", providing customers with one-stop services such as equipment installation and commissioning, operation training, technical consultation, after-sales maintenance, etc., establishing a rapid response mechanism, timely solving various problems encountered by customers during use, and eliminating worries.

With the continuous development of the photovoltaic industry towards high efficiency, intelligence, and safety, precise and efficient detection equipment has become a key support for ensuring the power generation efficiency of power plants and reducing operation and maintenance costs. The launch of the LAILX LX-PV31 portable IV tester in Suzhou not only fills the gap in the segmentation of high-end 1500V portable IV testing equipment, but also leads the industry upgrade with technological innovation, injecting strong impetus into the healthy and sustainable development of the global photovoltaic industry.
