In the wave of rapid development of the global photovoltaic industry, precise detection of the power generation performance of photovoltaic modules and strings is the core link of power station construction acceptance, daily operation and maintenance, and efficiency optimization. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of new energy testing for many years. With profound technical accumulation and continuous innovation capabilities, it has launched the LX-PV31 portable IV tester. This device has the core advantages of 1500V/30A wide range, 10 second high-speed detection, and high-precision data output, breaking the performance bottleneck of traditional detection equipment and providing an efficient, accurate, and portable integrated solution for the full life cycle performance testing of photovoltaic power plants, becoming a benchmark product in the field of photovoltaic operation and maintenance.

Under the background of large-scale development of photovoltaic power plants, traditional IV testers generally suffer from pain points such as insufficient range, slow detection speed, low accuracy, and poor portability. The current mainstream equipment mostly has a specification of 1000V/20A, which is difficult to adapt to the working current detection requirements of around 30A for 1500V high-voltage string and half piece components; At the same time, the detection process is cumbersome and the single test takes a long time, which cannot meet the efficiency requirements of large-scale power plant batch inspections; In addition, some equipment has insufficient accuracy and is easily affected by environmental light and temperature interference, resulting in detection data deviation and affecting the accuracy of power plant performance evaluation and fault diagnosis. The LAILX R&D team directly addresses industry pain points, relying on independently developed high-precision load modules and intelligent algorithms to create the LX-PV31 portable IV tester, achieving comprehensive breakthroughs in range, speed, accuracy, and portability, and accurately matching the high-voltage and high-efficiency development needs of the photovoltaic industry.

The core advantage of LX-PV31 portable IV tester lies in the perfect integration of wide range adaptation and high-precision detection. The device supports 1500VDC high-voltage string testing, with a current range covering 0.01~30A, perfectly solving the problem of insufficient range of traditional equipment. It can fully adapt to the detection needs of various photovoltaic modules and strings such as monocrystalline silicon, polycrystalline silicon, double glass, and half sheet. In terms of accuracy, the voltage testing accuracy reaches 0.1V, with an accuracy of ± 0.5% ± 0.2V; the current testing accuracy is 0.001A, with an accuracy of ± 0.5% ± 0.02A; the repeatability of high-power testing is controlled within ± 0.5% ± 3W, and the power accuracy converted to STC standard conditions is better than ± 5%, ensuring that each set of test data is accurate and reliable, providing authoritative data support for component level determination and power generation efficiency evaluation.

The efficient and convenient operation experience is another core highlight of LX-PV31. The device adopts an integrated portable design, with a compact and lightweight body, and is equipped with a high-strength protective box, making it easy to carry to various complex power plant sites such as mountains, deserts, and rooftops. It can be easily transported and operated by a single person. Equipped with a 6.5-inch high brightness color touch screen, visible under sunlight, supporting dual operation of touch screen and keyboard, bilingual interface in Chinese and English, simple and clear operation logic, even beginners can quickly get started. The detection efficiency has been greatly improved. Single component or string detection can complete the synchronous acquisition and analysis of 16 core parameters, including IV curve, PV curve, short-circuit current, open circuit voltage, peak power, conversion efficiency, etc., in just 10 seconds. This completely eliminates the drawbacks of traditional equipment waiting for a long time and greatly improves the efficiency of batch inspection of power plants.

To adapt to complex outdoor detection environments, LX-PV31 is equipped with a wireless radiometer and temperature sensing module. The host and irradiation probe support 100 meter wireless communication, which can synchronously collect environmental parameters such as irradiance, environmental temperature, and component temperature in real time, comprehensively record the environmental status during testing, and ensure that the detection data is traceable and comparable. The device is equipped with a large capacity memory that can store over 2000 test waveforms. It supports SD card expansion and USB data export, and is paired with dedicated IV curve analysis software to quickly generate detection reports and achieve deep analysis and management of data. It provides a complete data solution for power plant operation and maintenance, third-party testing, and scientific research institutions. In addition, the equipment has complete overvoltage, overcurrent, and short-circuit protection functions, adapts to a wide temperature range of -10 ℃ to 50 ℃, has strong anti-interference ability, and can still operate stably under harsh outdoor conditions such as strong light, high temperature, and humidity. Its reliability and durability are tested in harsh scenarios.

With excellent performance and reliable quality, the LX-PV31 portable IV tester has been widely used in various scenarios such as photovoltaic power plant construction acceptance, daily operation and maintenance, component selection, third-party testing, scientific research and teaching. In large ground power stations, batch detection of high-voltage strings can be quickly completed, and inefficient components and faulty strings can be accurately located; In the operation and maintenance of distributed photovoltaic power plants, the advantage of portability is highlighted, which can flexibly complete performance testing of small power plants such as roofs and households; In the process of component production and selection, the A/B/C level component grades can be accurately determined, efficient components can be screened, and the power generation efficiency of the power station can be guaranteed from the source. At present, the equipment has been highly recognized by many power plant owners, operation and maintenance enterprises, and testing institutions, with excellent market reputation, helping multiple photovoltaic projects achieve quality and efficiency improvement in operation and maintenance, and maximizing power generation revenue.

As an innovative leader in the field of new energy detection equipment, Suzhou LAILX has always adhered to the research and development concept of "precision, efficiency, portability, and reliability", focusing on the pain points and needs of the photovoltaic industry, and continuously launching high-quality detection equipment. The LX-PV31 portable IV tester launched this time is not only a concentrated reflection of LAILX's technological innovation capabilities, but also an important support for promoting the standardization and efficient development of the photovoltaic testing industry. In the future, LAILX will continue to deeply cultivate the field of new energy detection, increase research and development investment, break through core technologies, launch more innovative products that meet market demand, provide solid technical support and equipment guarantee for the high-quality development of the global photovoltaic industry, and help achieve the "dual carbon" goal as soon as possible.
