Under the accelerating trend of the global photovoltaic industry iterating towards 1500V high-voltage systems and high-power components, the demand for photovoltaic module power generation efficiency testing, power station acceptance and operation, and third-party quality inspection is 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 adapt to the efficient detection needs of large-scale photovoltaic power plants. Shanghai LAILX has been deeply involved in the field of photovoltaic testing for many years. With profound technical accumulation and industry insights, it has launched the LX-PV31 portable IV tester, which solves industry testing problems with its core advantages of precision, efficiency, and portability, injecting hardcore power into the high-quality development of the photovoltaic industry.

As a LAILX standard photovoltaic module IV curve testing equipment, LX-PV31 accurately targets the performance shortcomings of traditional equipment, achieving comprehensive breakthroughs in core performance. The device supports a large testing range of 1500V/30A, perfectly adapting to the current mainstream 1500V high-voltage photovoltaic system and high-power component testing needs, completely solving the pain point of insufficient range of traditional 1000V/20A devices, 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. It can accurately capture more than 20 core parameters such as IV curve, PV curve, short-circuit current, open circuit voltage, peak power, filling factor, conversion efficiency, etc., providing accurate data support for component performance evaluation.

Efficient and convenient design greatly improves the efficiency of outdoor inspection operations. The LX-PV31 adopts an integrated portable chassis design, with a lightweight and sturdy body, suitable for complex outdoor work environments, and can be easily carried and operated by a single person. The device is equipped with a high brightness sunlight visible color touch screen, paired with a physical keyboard, with a simple and intuitive operation interface that supports switching between Chinese and English. Novices can quickly get started without training. In terms of core detection efficiency, LX-PV31 achieves 10 second high-speed scanning, and single component or string detection is completed in one step, improving efficiency by more than 50% compared to traditional devices; The internal memory can store more than 2000 test waveforms, and the built-in SD card slot supports storage space expansion. Combined with wireless data transmission function, it can export detection data with one click, which is convenient for later analysis and report generation.

Relying on LAILX's comprehensive R&D and service system, LX-PV31 has undergone strict quality control from R&D to production. The core components are equipped with industrial grade configurations and have high-voltage isolation protection and overvoltage/overcurrent protection functions, ensuring the safe and stable operation of the equipment in high-voltage testing scenarios. At present, LX-PV31 has been widely used in major photovoltaic power stations, module production enterprises, and third-party testing institutions in China, and exported to overseas markets such as North America and the Middle East. With stable performance and precise testing capabilities, it has gained high recognition from industry customers.
