In the wave of rapid development of the global new energy industry, the construction scale and component quality control of photovoltaic power plants have become the core issues of the industry. As a benchmark enterprise in the field of photovoltaic testing, LAILX in Suzhou has launched the LX-PV31 portable IV tester with deep technical accumulation and innovative research and development capabilities. With its core advantages of precision, efficiency, and portability, LAILX fully empowers the full life cycle testing of photovoltaic power plants, providing solid technical support for plant acceptance, operation, and quality control.

LX-PV31 is a portable device designed specifically for photovoltaic string performance testing, with a core focus on precise testing of 1500V photovoltaic strings, perfectly adapting to the power testing needs of current mainstream half cell modules. The device adopts an integrated packaging design, with a compact and lightweight body, and a dedicated protective box. It can be easily carried to the power plant site by a single person without complex installation. It can be put into use immediately after opening the box, completely breaking the space and scene limitations of traditional large-scale testing equipment.
In terms of testing performance, LX-PV31 has achieved industry-leading precision and speed. The device supports 1500V/30A wide range testing and can accurately capture core parameters such as the IV curve, open circuit voltage, short-circuit current, maximum power, and fill factor of photovoltaic modules under natural light, comprehensively covering key indicators for component performance evaluation. Relying on the high-precision capacitive/resistive load module developed by Laikesi, the equipment can complete a complete single string test in just 10 seconds, with a testing interval of 35 seconds. It supports uninterrupted continuous scanning, greatly improving the efficiency of batch testing in power plants.

To adapt to complex outdoor environments, LX-PV31 is equipped with multiple practical functions. The device is equipped with a high-precision irradiance meter and temperature sensor, which can synchronously collect data on environmental temperature, component temperature, solar irradiance, etc. It automatically completes STC standard condition correction to ensure that test results are not affected by environmental fluctuations. At the same time, the device is equipped with a high brightness color touch screen visible under sunlight, supporting both Chinese and English operation interfaces, and one click data export. The operation is simple and intuitive, and maintenance personnel can quickly get started.

In terms of data management, LX-PV31 has powerful storage and analysis capabilities. The machine can store over 2000 test waveforms, and the built-in SD card slot supports storage space expansion. The data can be synchronized to PC specific analysis software through the USB interface, achieving full process management such as data archiving, curve comparison, and report generation. The device also supports barcode scanning function, which can quickly identify component numbers, achieve precise binding of test data and component information, and establish a complete quality file for the power station.

In terms of application scenarios, LX-PV31 covers the full process detection requirements of photovoltaic power plants. During the construction phase of the power station, it can be used for component arrival acceptance, installation quality sampling, and screening of unqualified components; During the operation and maintenance phase, it is possible to regularly detect the performance degradation and fault location of the string, and promptly troubleshoot the issue of decreased power generation efficiency; Third party testing institutions and research institutions can use it as a standard testing tool to provide objective and accurate testing data for the photovoltaic industry.

LAILX has been deeply involved in the field of photovoltaic testing for many years, always driving industry progress with technological innovation. The launch of LX-PV31 portable IV tester is another important breakthrough for Lexus in the field of photovoltaic detection equipment. With its core advantages of "portability, precision, efficiency, and intelligence", it solves the pain points of traditional detection equipment and helps photovoltaic power plants achieve more efficient, safe, and economical operation. In the future, Lexus will continue to focus on the demand of the photovoltaic industry, launch more high-performance testing equipment, and contribute to the high-quality development of the global new energy industry.
