Under the accelerating trend of the global photovoltaic industry iterating towards 1500V high-voltage systems and high-power components, the standards for power generation efficiency testing, grid connection acceptance, and later operation and maintenance of photovoltaic power plants are becoming increasingly stringent. Traditional IV testing equipment generally suffers from pain points such as insufficient range, cumbersome operation, and poor outdoor adaptability, making it difficult to meet the efficient detection needs of large-scale photovoltaic power plants. In response to the current situation of this industry, Shanghai LAILX has launched the LX-PV31 portable IV tester, which has the core advantages of precision, efficiency, and portability, comprehensively solving the industry's detection problems and injecting hardcore power into the high-quality development of the photovoltaic industry.

As a standard photovoltaic module IV curve testing equipment, LX-PV31 has achieved comprehensive breakthroughs in core performance. The device supports a large testing range of 1500V/30A, perfectly adapting to the current mainstream high-voltage photovoltaic systems and high-power component testing needs, completely solving the shortcomings of traditional equipment's insufficient range, covering more than 95% of photovoltaic panel specifications. In terms of detection accuracy, LX-PV31 is equipped with a high-precision testing module, with voltage measurement accuracy of ± 0.1V, current measurement accuracy of ± 0.001A, and testing accuracy controlled within the range of ± 0.5% ± 0.2V. The device can accurately capture more than 20 core parameters such as IV curve, short-circuit current, open circuit voltage, peak power, fill factor, conversion efficiency, etc., providing solid data support for component performance evaluation.

In terms of efficient and convenient design, LX-PV31 significantly improves the efficiency of outdoor inspection operations. The device adopts an integrated portable chassis design, with a lightweight and sturdy body that can be easily carried and operated by a single person. Equipped with a high brightness sunlight visible color touch screen and a physical keyboard, the operation interface is simple and intuitive, supporting switching between Chinese and English, and beginners can quickly get started without training. In terms of core detection efficiency, LX-PV31 achieves a 10 second high-speed scan, with single component or string detection completed in one step, improving efficiency by more than 50% compared to traditional devices. At the same time, the internal memory can store more than 2000 test waveforms, and the built-in SD card slot supports expansion. With wireless data transmission function, detection data can be exported with one click, greatly facilitating later analysis and report generation.

LX-PV31 has full scene adaptation capability, which can cover the detection needs of the entire photovoltaic industry chain. The device comes with environmental temperature, solar panel temperature, and irradiance detection probes that can synchronously record testing environment parameters. It supports STC nominal parameter conversion testing and automatically calculates the current power generation efficiency and conversion rate of the components. Whether it is string testing for distributed photovoltaic power plants, large-scale ground power plants, or factory testing for component manufacturing enterprises and the diverse needs of third-party testing institutions, LX-PV31 is capable of handling it. Relying on a comprehensive R&D and service system, LX-PV31 has undergone strict quality control from research and development to production. The core components are equipped with industrial grade configurations and have high-voltage isolation and overvoltage/overcurrent protection functions, ensuring the safe and stable operation of the equipment in complex scenarios. It has become an indispensable "precision detection manager" for the entire photovoltaic industry chain.
