In the current rapid iteration of the global photovoltaic industry towards high voltage and high power, the performance testing of photovoltaic modules and power plants is facing higher requirements. Traditional IV testing equipment commonly suffers from pain points such as insufficient range, cumbersome operation, and poor outdoor adaptability, making it difficult to meet the testing needs of 1500V high-voltage systems and large-sized components. 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 industry insights, it has launched the LX-PV31 portable IV tester, which redefines the portable IV testing standards with the core advantages of precise testing, efficient operation, and portable design, providing a one-stop efficient solution for photovoltaic module production quality inspection, power station operation and maintenance, and third-party testing.

At present, the 1500V high-voltage system has become the mainstream configuration of large photovoltaic power plants, and the market share of high-power components such as half panels and stacked panels continues to rise. Traditional IV testers with a range of 1000V/20A frequently encounter problems such as range exceeding and large test data deviation when facing new scenarios, seriously affecting detection efficiency and result reliability. LX-PV31 accurately anchors industry pain points, achieving a breakthrough in core performance. The maximum test voltage of the equipment can reach 1500V, the upper limit of the test current can be expanded to 30A, and the effective test power covers 50W-30kW. It perfectly adapts to the testing needs of 1500V high-voltage strings and large-sized high-power components, solving the industry problem of insufficient range of traditional equipment from the root.

In terms of detection accuracy, LX-PV31 demonstrates a professional level, with a voltage measurement accuracy of 0.1V and a current measurement accuracy of 0.001A. It can accurately capture subtle parameter changes during the power generation process of photovoltaic modules, accurately draw IV curves, and provide reliable data support for component efficiency evaluation and fault diagnosis. The equipment is equipped with a high-precision irradiance meter and temperature sensor, which can synchronously detect the ambient temperature, solar panel temperature, and light intensity, comprehensively record the testing environment parameters, eliminate the interference of environmental factors on the test results, ensure accurate and traceable data, and meet the requirements of international testing standards such as IEC 61215.

The efficient and convenient design is another major highlight of LX-PV31. The equipment adopts an integrated packaging body, with a sturdy and durable structure, suitable for outdoor complex and harsh environment operations; Equipped with a high brightness color touch screen visible under sunlight, paired with a physical keyboard, the Chinese and English operation interface is clear and easy to understand, making it easy for beginners to quickly get started. Single component or string detection can be completed in just 10 seconds, increasing efficiency by over 50% compared to traditional devices; Built in multiple specifications of photovoltaic panels, supporting one click import, reducing the tedious operation of switching and testing components of different specifications, and significantly reducing labor costs.

To meet the flexible outdoor work requirements, LX-PV31 continues to optimize in terms of portability and intelligence. The host and probe adopt wireless connection technology, supporting wireless communication up to 100 meters, freeing themselves from cable constraints, and adapting to complex power station scene detection; Equipped with a patented probe box and temperature probe mounting bracket, it can quickly fix the probe and improve work efficiency; Unique barcode scanning function, which can achieve intelligent recognition of components, automatically match parameters and store data; The internal memory can store over 2000 test waveform data and supports one click export of data to a computer, facilitating subsequent analysis and report generation, meeting the data archiving needs of third-party testing institutions.

As a LAILX standard photovoltaic module IV curve testing equipment, LX-PV31 has focused on the actual needs of the industry since its inception. After multiple rounds of outdoor scene testing and technical optimization, the stability and reliability of the product have been fully verified. At present, this device has been widely used in scenarios such as factory quality inspection of photovoltaic modules, grid connection acceptance of power stations, daily operation and maintenance inspections, and third-party testing, and has been highly recognized by numerous photovoltaic enterprises, power station operators, and testing institutions.

In the future, LAILX in Suzhou will continue to deeply cultivate the field of photovoltaic detection technology, with independent innovation as the core driving force, continuously optimize product performance, expand product application scenarios, and launch more high-end detection equipment that meets industry needs. The heavyweight launch of the LX-PV31 portable IV tester is not only a concentrated reflection of LAILX's technological strength, but also will promote the upgrading of the photovoltaic detection industry towards precision, efficiency, and portability, help promote the high-quality development of China's photovoltaic industry, and contribute China's intelligent manufacturing strength to the global clean energy industry.
