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 is as high as ± 0.1% FS, and the current measurement accuracy is ± 0.2% FS. It can accurately capture subtle changes in the IV curve, accurately obtain key parameters such as open circuit voltage, short-circuit current, peak power, fill factor, and conversion efficiency, and provide reliable data support for component quality evaluation and fault diagnosis. At the same time, the device is equipped with a high-precision irradiance meter and temperature sensor, which can synchronously collect environmental temperature, component temperature, irradiance and other data, achieving synchronous recording of test data and environmental parameters, ensuring the scientific and reference value of the test results.

Efficient and convenient is another major highlight of LX-PV31, Lex. The device adopts integrated packaging technology, with a compact and lightweight body weighing less than 6kg, and an external size of only 390300200mm. The operation and maintenance personnel can hold it in one hand and shuttle between photovoltaic arrays, suitable for complex work scenarios such as roofs and mountains, without the need for additional equipment transportation. In terms of operation, the device is equipped with a 6.5-inch color LCD touch screen, supporting bilingual operation interface in Chinese and English, with clear and easy to understand functional instructions, even novice operators can quickly get started; Equipped with one click detection and data export functions, the detection speed of a single component/string only takes 10 seconds, which significantly improves efficiency compared to traditional equipment and greatly shortens the detection time of large-scale photovoltaic power plants. At the same time, the device is equipped with a high-capacity replaceable lithium battery module, which can achieve 8 hours of continuous battery life on a single charge, perfectly solving the problem of insufficient power supply for outdoor operations.

In terms of intelligence and data management, LX-PV31 performs equally well. The host and irradiation probe are connected wirelessly, providing a maximum wireless communication connection of 100 meters, making testing more convenient and flexible. The device is equipped with rich peripheral interfaces, supporting multiple data transmission methods such as USB flash drive, Bluetooth, WiFi, etc. The detection data can be exported in real time to a computer or mobile device for easy analysis and archiving in the future. The internal memory can store over 2000 test waveform data, meeting the data storage requirements for large-scale power plant batch testing. In addition, the device comes with barcode scanning function, which can achieve intelligent recognition of components, quickly match component information with test data, simplify the detection process, and improve the efficiency of operation and maintenance management.

With excellent performance and reliable quality, the LX-PV31 portable IV tester has been widely used in various scenarios such as centralized ground power stations, industrial and commercial distributed photovoltaics, and household photovoltaics since its launch, becoming the first choice equipment for power station construction units, operation and maintenance teams, and third-party testing institutions. Whether it is component performance sampling during the completion and acceptance stage of power plants, troubleshooting of faulty components in daily operation and maintenance, or research on photovoltaic module performance by scientific research institutions, LX-PV31 can successfully complete testing tasks with its advantages of precision, efficiency, and portability, providing solid guarantees for the safe and stable operation and power generation efficiency improvement of photovoltaic power plants.
