Driven by the "dual carbon" goal, the photovoltaic industry is experiencing a wave of large-scale and efficient development. Double glass modules have become the mainstream in the market due to their high durability, long lifespan, and other advantages. However, their high voltage and high current characteristics impose strict requirements on detection equipment. LAILX has been deeply involved in the field of photovoltaic testing for many years. With its profound technical accumulation and continuous innovation capabilities, it has launched the LX-PV33 portable IV tester, which has a 2000V/40A ultra wide range, dual glass module exclusive testing algorithm, and portable intelligent design. It accurately solves the pain points of industry testing, provides a hardcore solution for photovoltaic module performance evaluation, power plant operation and maintenance, and quality acceptance, and sets a new benchmark in the field of photovoltaic IV testing.

The IV curve testing of photovoltaic modules is a core means of evaluating power generation efficiency, conversion rate, and health status. Traditional equipment generally has problems such as insufficient range, poor double glass adaptation, and low accuracy, making it difficult to adapt to the current testing needs of high-power double glass modules. As the flagship level IV testing equipment of LAILX, LX-PV33 breaks through technical bottlenecks and achieves a leapfrog upgrade in core performance. In terms of range specifications, the equipment breaks the industry's conventional limit of 1000V/20A, supports high-precision testing of 0-2000V voltage and 0-40A current, perfectly adapts to high-power double glass components and string detection, solves the measurement problem of working current of about 20A for half piece components, and covers more than 95% of mainstream photovoltaic module specifications. In terms of detection accuracy, the resistance testing module developed by Laikesi is used, with a voltage measurement accuracy of 0.1V and a current measurement accuracy of 0.001A. The testing accuracy is controlled within the range of ± 0.5% ± 0.2V and ± 0.5%+0.02A, with excellent repeatability accuracy, ensuring the authenticity and reliability of single component and string detection data, and accurately reflecting the power generation performance of components.

In response to the double-sided power generation characteristics of double glass components, LX-PV33 is equipped with a patented multi irradiation algorithm, which can accurately shield the interference of back panel electrical energy, independently calculate the power generation efficiency and STC conversion value of the front battery cells, solve the industry problem that traditional equipment cannot distinguish the performance of the front and back sides of double-sided components, and provide scientific basis for quality grading and defect determination of double glass components. The device supports fully automatic scanning of IV curves, conversion of STC nominal parameters, synchronous collection of irradiance, and analysis of power generation. Single component or string detection can be completed in just 10 seconds, and standardized testing reports can be generated with just one click, greatly improving the efficiency of power station inspection, arrival quality inspection, and third-party testing. At the same time, it is equipped with a built-in photovoltaic module correction database, which can automatically match the parameters of different specifications of components, quickly switch testing modes, without the need for manual cumbersome settings, and adapt to the rapid detection needs of multiple scenarios.

In terms of portability and intelligent design, LX-PV33 fully meets the needs of outdoor work scenarios, adopting integrated lightweight packaging technology. The whole machine is compact and portable, and is equipped with a dedicated protective box. It can be easily carried by a single person to complex working conditions such as roofs, mountains, deserts, etc., completely eliminating the limitations of traditional large-scale equipment transportation and deployment. The device is equipped with a high brightness sunlight visible color touch screen, supporting dual operation of touch screen and keyboard, switching between Chinese and English interfaces, clear and intuitive functional layout, and non professionals can quickly get started. Built in large capacity replaceable lithium battery with a battery life of over 10 hours, suitable for all day outdoor testing operations; Supports wireless data transmission and USB fast export, which can be synchronized to the PC for in-depth data analysis and report printing, facilitating data archiving and traceability management. In addition, the equipment has safety protection functions such as high-voltage isolation power supply design, overvoltage and overcurrent protection, and automatic range switching, which ensure the safety of operators and equipment from the hardware level and are suitable for photovoltaic high-voltage system detection scenarios.

With its core advantages of precision, efficiency, portability, intelligence, safety, and reliability, the LX-PV33 portable IV tester has been widely used in the full lifecycle detection scenarios of photovoltaic power plants. During the component arrival acceptance process, it is possible to quickly screen for components with substandard power generation efficiency, hidden cracks, attenuation, and other issues, in order to prevent inferior products from entering the installation process; In the daily operation and maintenance of power plants, regular inspections can timely detect hidden dangers such as component aging, hot spots, and diode failures, accurately locate performance degradation areas, provide data support for operation and maintenance decisions, and reduce power generation losses; In the field of third-party testing and scientific research, its high-precision testing capability can meet professional needs such as component quality certification, technology research and development, and performance comparison.

As a leading local photovoltaic testing equipment enterprise, Suzhou Laikesi has always adhered to independent research and technological innovation. The launch of LX-PV33 not only fills the gap of high-end double glass module IV testing equipment in China, but also breaks the monopoly of the imported equipment market with high cost-effectiveness. The company has established a comprehensive after-sales service system, providing 24-hour technical response, 1-year original factory warranty, free software and hardware upgrades, and customized solution services to completely solve users' worries. In the future, LAILX will continue to focus on innovation in photovoltaic detection technology, providing higher quality products and services to support the high-quality development of the photovoltaic industry and contribute local strength to the global energy transformation.
