As a LAILX standard photovoltaic module IV curve testing equipment, LX-PV31 has achieved multiple breakthroughs in core performance, accurately adapting to the testing requirements of 1500V high-voltage photovoltaic string systems. It can stably complete the power generation characteristic testing of photovoltaic modules and strings in the range of 50W to 30kW, completely solving the industry problem of insufficient 1000V range limit for traditional equipment. The voltage measurement accuracy of the equipment can reach 0.1V, and the current measurement accuracy can reach 0.001A. It can accurately capture the changes in the power generation parameters of photovoltaic modules under different lighting and temperature conditions, providing reliable data support for component performance evaluation and fault diagnosis. Whether it is single component factory quality inspection, photovoltaic power station grid connection acceptance, or daily operation and maintenance of power generation attenuation investigation and hidden crack component positioning, LX-PV31 is capable of handling them and has become the core equipment for quality control throughout the entire lifecycle of photovoltaics.

Portability and outdoor adaptability are one of the core advantages of LX-PV31. The equipment adopts an integrated compact design, with a light weight and small volume, and is equipped with a high-strength protective box. It can be easily carried to various complex outdoor scenes such as mountains, deserts, rooftops, etc., and can be transported and operated by a single person, completely bidding farewell to the difficulties of transportation and deployment of traditional large testing equipment. The body adopts a waterproof and dustproof design, which can adapt to extreme temperature environments ranging from -20 ℃ to 60 ℃. It is not afraid of outdoor sun exposure, rain, and sandstorms, and can still operate stably under harsh working conditions, ensuring continuous testing work. At the same time, the device is equipped with a high brightness color touch screen visible under sunlight, coupled with a simple and intuitive operating interface. Even in strong light environments, data can be viewed clearly and operated smoothly without the need for additional shading devices, greatly improving outdoor detection efficiency.

With the support of intelligent functions, detection is more efficient and data management is more convenient. The LX-PV31 is equipped with a high-speed scanning module, and single string IV curve detection can be completed in just 10 seconds, which increases efficiency by more than 50% compared to traditional equipment, significantly shortens the power station inspection cycle, and reduces operation and maintenance costs. The device is equipped with a high-precision irradiance meter and temperature sensor, which can synchronously collect environmental temperature, component temperature, and solar irradiance data. It automatically completes STC standard condition correction, eliminates the interference of environmental factors on the detection results, and ensures data accuracy and comparability. At the same time, it supports 100 meter wireless communication and can remotely synchronize data to mobile phones or computers. Paired with dedicated analysis software, it can quickly generate detection reports and export data reports, meeting the needs of power plant operation and maintenance archives retention, third-party detection report issuance, etc. In addition, the device comes with a large capacity storage that can store over 2000 sets of test data, and supports one click data export for easy traceability and analysis in the future.

Secure design strengthens the defense line and adapts to the requirements of high-voltage detection scenarios. LX-PV31 adopts a high-voltage isolation design, with overvoltage, overcurrent, and reverse connection protection functions, which can effectively avoid safety accidents caused by operational errors or equipment failures, ensuring the safety of operators and equipment. The insulation performance of the equipment meets industry safety standards and can operate stably in a 1500V high voltage environment without fear of high voltage impact, adapting to the current mainstream high voltage photovoltaic system testing needs. At the same time, equipped with anti electric shock interface design, the risk of leakage is eliminated during the wiring process, further improving operational safety and allowing operation and maintenance personnel to carry out high-voltage testing work with confidence.

With excellent performance and reliable quality, the LX-PV31 portable IV tester has been widely used in photovoltaic module production enterprises, large photovoltaic power stations, third-party testing institutions, research institutions and other scenarios, and has been highly recognized by industry customers. In the future, LAILX in Suzhou will continue to deeply cultivate the field of photovoltaic testing, focus on industry pain points and customer needs, continuously optimize product performance, upgrade intelligent functions, launch more high-precision, highly portable, and highly reliable testing equipment, and help the photovoltaic industry develop towards high efficiency, intelligence, and safety, contributing Chinese strength to the global new energy industry.
