In the wave of global photovoltaic industry's comprehensive iteration towards 1500V high-voltage systems, on-site IV curve detection in power plants faces core pain points such as insufficient range, poor portability, low data accuracy, and weak outdoor adaptability, which seriously restrict the quality inspection of photovoltaic modules, power plant acceptance, and the improvement of operation and maintenance efficiency. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of photovoltaic testing for many years. With its core technology research and development strength and rich industry experience, it has launched the LX-PV31 portable IV tester, which redefines the standard for portable photovoltaic IV testing with a 1500V/30A ultra large range, high-precision measurement, ultimate portable design and intelligent integration function, providing efficient solutions for photovoltaic full scene testing and helping the high-quality development of the photovoltaic industry.

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 reaches 0.1V, the current measurement accuracy is as high as 0.001A, and the testing accuracy is controlled within ± 0.5% ± 0.2V. It can accurately capture more than 20 key parameters such as I-V curve, P-V curve, short-circuit current, open circuit voltage, peak power, fill factor, conversion efficiency, series resistance, parallel resistance, etc., comprehensively covering the core indicators of photovoltaic module power generation performance evaluation, providing authoritative data support for power plant design, acceptance, and operation.
To adapt to complex outdoor work scenarios, LX-PV31 adopts integrated packaging technology. The body structure is sturdy and durable, with good dustproof, moisture-proof, and seismic performance. It can adapt to harsh environments such as high temperature, low temperature, sand and dust, and humidity, ensuring long-term stable operation in the wild. The device host and detection probe adopt a dual communication mode of Bluetooth+RS232 serial port, with a wireless transmission distance of up to 100 meters. The signal transmission is stable and anti-interference, and real-time data synchronization can be achieved even in the dense electromagnetic environment of the power plant. This not only ensures that operators stay away from high-voltage components, improves work safety, but also breaks the cable length limit, making it easy to complete rapid inspection of large-scale photovoltaic arrays. Equipped with a patented probe box and temperature probe mounting bracket, the probe can be quickly fixed. It is paired with a high brightness color touch screen visible under sunlight and a keyboard dual operation mode. The Chinese and English interfaces are clear and intuitive, making it easy for beginners to get started quickly. Single component or string detection can be completed in just 10 seconds, greatly improving outdoor detection efficiency.

Intelligent functional design is one of the core highlights of LX-PV31. The device is equipped with a database of mainstream photovoltaic module parameters both domestically and internationally, covering over 95% of the module specifications available in the market. It supports one click parameter matching, eliminating the need for manual complex settings and allowing for quick switching between different specification components for testing. Equipped with barcode scanning function, it can quickly identify component information, achieve intelligent binding between components and test data, and facilitate later traceability management. The internal memory can store over 2000 test waveform data and supports one click export to the PC end. Equipped with professional analysis software, it can achieve deep data analysis and automatic report generation, greatly reducing manual workload. Simultaneously integrating environmental temperature, solar panel temperature, and irradiance detection probes, it can synchronously record test environmental parameters, automatically complete STC nominal parameter conversion and IV compensation, eliminate the influence of environmental factors on test results, and ensure accurate and reliable data.

Thanks to its outstanding performance and scene adaptation capabilities, LX-PV31 has been widely used in various scenarios such as distributed photovoltaic power plants, mountain photovoltaics, surface photovoltaics, module production quality inspection, and third-party testing institutions. In the operation and maintenance of distributed power plants, it is possible to quickly complete the performance inspection of string generation, accurately locate inefficient components and faulty strings; In the component production process, it can be used for factory quality inspection to strictly control the power generation efficiency and stability of the product; During the acceptance stage of the power station, authoritative testing data can be provided as the core basis for quality assessment of the power station. Since its launch, LX-PV31 has been widely recognized by industry customers for its stable performance, accurate data, and convenient operation, and has been exported to multiple countries and regions at home and abroad, becoming a benchmark product in the field of photovoltaic testing.

In the future, LAILX in Suzhou will continue to deepen its innovation in photovoltaic testing technology, focus on industry pain points and customer needs, continuously optimize product performance, enrich product functions, and empower the development of the photovoltaic industry with higher quality products and services. The launch of LX-PV31 portable IV tester not only demonstrates LAILX's technical strength in the field of photovoltaic detection, but also promotes the upgrading of photovoltaic detection equipment towards high voltage, precision, portability, and intelligence through practical actions, injecting strong impetus into the efficient, safe, and sustainable development of the global photovoltaic industry.
