At present, as the photovoltaic industry moves from high-speed construction to refined operation and maintenance, the quality of post operation and maintenance of power plants directly determines the long-term investment returns of projects. However, traditional IV detection equipment generally suffers from pain points such as bulky body, cumbersome wiring, and poor adaptability to outdoor environments, making it difficult to adapt to the rapid inspection needs of complex sites such as mountains and rooftops. In response to the pain points in this industry, Shanghai LAILX has launched the LX-PV32 portable IV tester, which redefines the new benchmark for string detection with its three core advantages of high precision, strong portability, and intelligence.

LX-PV32 is tailor-made for the current mainstream 1500V photovoltaic string system, with a maximum measurement range of 1500VDC/20A, perfectly adapting to the high-voltage testing needs of over 95% of mainstream photovoltaic modules and strings. The equipment adopts a self-developed high-precision testing module, with a voltage measurement accuracy of ± 0.5% ± 0.2V and a current measurement accuracy of ± 0.5% ± 0.01A. It can fully measure the I-V and P-V characteristic curves and synchronously output more than 20 key parameters such as short-circuit current, open circuit voltage, peak power, and conversion efficiency. At the same time, the built-in high-precision irradiance meter and temperature sensor can synchronously collect environmental data and perform real-time compensation calibration, completely eliminating the interference of environmental factors on the detection results and ensuring absolute accuracy of data under different working conditions.

LX-PV32 has achieved breakthrough innovation in portability and on-site operation efficiency. The device adopts an integrated and sturdy packaging, with a built-in large capacity rechargeable lithium battery, which can work continuously in the field for a long time without the need for external mains power. The host and irradiation temperature probe support wireless communication up to 100 meters away, completely eliminating the tedious long-distance wiring on site and greatly simplifying the wiring process. Combined with a 6.5-inch bright sunlight visible color touch screen and physical button dual operation mode, single component or string detection can be completed in just 10 seconds, reducing deployment time by more than 80% compared to traditional devices, truly achieving "testing on the go and inspection on the go".

Intelligent operation and data analysis are another major highlight of LX-PV32. The device is equipped with a global mainstream photovoltaic module specification database, supporting one click import of parameters and barcode scanning recognition, automatically matching detection standards and associating archived data. After the test is completed, PDF and Excel reports can be exported with just one click, and PR system performance ratio calculation is supported to help engineers accurately distinguish whether the power generation decline is caused by component performance degradation or external line losses, providing clear guidance for operation and maintenance.

Thanks to its outstanding performance, LX-PV32 has been widely used in various scenarios such as large-scale ground power station acceptance, daily operation and maintenance inspections, third-party quality appraisal, and scientific research experiments. Suzhou LAILX always adheres to driving industry progress through technological innovation. The launch of LX-PV32 is not only a precise response to industry pain points, but also provides solid hardware support for the quality control of the entire lifecycle of photovoltaic power plants, helping the new energy industry to develop towards high efficiency and intelligence with high quality.
