Range upgrade is the most core technological breakthrough of LX-PV33 portable IV tester, completely breaking the range limitations of traditional devices such as 1000V and 20A. This device is equipped with LAILX's self-developed resistive high-precision testing module, paired with imported high-speed sampling chips, to achieve accurate measurement of 0-2000V open circuit voltage and 0-40A short circuit current across the entire area. It is fully compatible with all single crystal, polycrystalline, half chip, stacked tile, double-sided double glass photovoltaic modules on the market, and is also suitable for high-voltage and large capacity string detection needs. Whether it is household small photovoltaic power plants, industrial and commercial distributed power plants, or high-power components and long-distance string of large ground photovoltaic power plants, it can achieve precise detection without dead corners, perfectly matching the current industry development trend of high-voltage and large current photovoltaic equipment.

The LX-PV33 is equipped with a dedicated multi irradiation intelligent correction algorithm to address the core pain points in the industry of double-sided double glass component testing. It can effectively shield the data interference caused by the back panel power generation of the component, independently calculate the core parameters such as the front cell power generation efficiency and STC conversion efficiency, accurately distinguish the front power generation and back gain data of the component, and solve the problem of large data deviation and inaccurate results in traditional equipment testing of double glass components. The equipment can quickly generate complete IV characteristic curves, accurately extract more than ten core data such as open circuit voltage, short-circuit current, maximum power, fill factor, conversion efficiency, etc. At the same time, it automatically completes data calibration and analysis, accurately locates hidden faults such as component attenuation, hidden cracks, virtual soldering, and string mismatch, and provides accurate data support for operation and maintenance personnel to identify equipment hazards and evaluate component performance.

In terms of device practicality and scene adaptability, LX-PV33 balances high precision and portability, perfectly adapting to complex outdoor work conditions. The device adopts an integrated lightweight design, with a compact and small body, abandoning the bulky and cumbersome structure of traditional detection equipment. It can be easily carried and operated independently by a single person, completely eliminating the limitations of laboratory space and fixed power supply. It can flexibly adapt to various complex outdoor work scenarios such as deserts, mountains, coasts, and rooftops. In terms of battery life, the device is equipped with a large capacity long-lasting lithium battery, which can work continuously for 8 hours on a single full charge, fully meeting the needs of large-scale inspections and batch testing of photovoltaic power plants throughout the day, greatly improving the efficiency of outdoor operation and maintenance work.

Safety protection design runs through the entire process of equipment development, providing comprehensive protection for the safety of operators and equipment. The LX-PV33 is equipped with a high-voltage isolation protection architecture and multiple protection mechanisms including overvoltage, overcurrent, overload, and reverse connection, effectively avoiding safety risks during high-voltage detection. At the same time, the equipment has excellent three proof performance, dust-proof, moisture-proof, and anti vibration, and can adapt to harsh outdoor environments such as high and low temperatures, high humidity, and high dust. It operates stably, has a low failure rate, and greatly reduces the maintenance costs of the equipment in the later stage. The device is equipped with a high-definition touch screen display, with a simple and intuitive operation interface. The intelligent operating system simplifies the detection process, without the need for professional debugging and training. Novices can quickly get started and complete the entire set of detection tasks.

As the core testing equipment for photovoltaic operation and maintenance, the LAILX LX-PV33 portable IV tester, with its comprehensive advantages of ultra large range, ultra-high precision, full field adaptation, safety and durability, accurately solves the industry pain points of new photovoltaic module testing and fills the market gap in portable testing of high-power and high-voltage photovoltaic modules. In the future, LAILX in Suzhou will continue to deepen its research and development of photovoltaic detection technology, continuously iterate and optimize product performance, empower the high-quality development of the photovoltaic industry with its hard core intelligent manufacturing strength, and safeguard the quality, efficiency, safety, and stable operation of photovoltaic power plants.
