In the booming trend of the global new energy industry, photovoltaics, as the core pillar of clean energy, have become increasingly crucial in controlling the scale of power plant construction and component quality. As a benchmark enterprise in the field of photovoltaic testing, LAILX in Suzhou has always driven industry progress with technological innovation. Recently, the LX-PV31 portable IV tester was launched, which provides an efficient and accurate integrated solution for photovoltaic module performance testing with high-precision testing capabilities, portable design, and intelligent operation experience, opening a new chapter in rapid on-site testing of photovoltaic power plants.

The IV characteristic curve of photovoltaic modules is the core basis for evaluating their power generation performance, conversion efficiency, and health status. Accurate IV test data has important guiding significance for power plant design, acceptance, operation and maintenance, and fault diagnosis. Traditional IV testing equipment often suffers from problems such as bulky size, complex operation, and inconvenient portability, making it difficult to meet the needs of field testing, distributed projects, and mobile detection in photovoltaic power plants. LAILX has been deeply involved in the field of photovoltaic testing for many years, providing precise insights into industry pain points. Based on its profound technical accumulation and extensive on-site application experience, it has independently developed and launched the LX-PV31 portable IV tester, breaking the limitations of traditional equipment and achieving a perfect balance between portability and accuracy.

The LX-PV31 portable IV tester has excellent core performance and can meet the testing needs of 1500VDC photovoltaic string systems. It supports a wide voltage range of 10V~1500V and a current range of 0.01A~30A for detection, and can test up to 30kW photovoltaic modules and strings. It is compatible with more than 95% of the specifications of photovoltaic panels on the market and has strong universality. The voltage measurement accuracy of the equipment is as high as ± 0.1V, the current measurement accuracy is ± 0.001A, and the testing accuracy is ± 0.5% ± 0.2V. It can accurately capture subtle changes in the IV curve, accurately measure more than ten key parameters such as short-circuit current, open circuit voltage, peak power, fill factor, conversion efficiency, etc., and provide reliable data support for the performance evaluation of photovoltaic modules.

In terms of design and operation, LX-PV31 fully embodies the concept of "portable, efficient, intelligent and convenient". The whole machine adopts integrated packaging technology, with a compact and sturdy structure, light weight, and is easy for single person carrying and field operations; The host and probe support 100 meter wireless communication, freeing themselves from cable constraints and adapting to complex power station testing scenarios. The device is equipped with a high brightness sunlight visible color touch screen, paired with keyboard operation. The Chinese and English interfaces are clear and easy to understand, and the functional layout is simple and intuitive, which can be quickly mastered without professional training; Built in massive photovoltaic panel specification data, supports one click import, quickly switches between different specification components for testing, single component or string testing can be completed in just 10 seconds, greatly improving testing efficiency.

To fully restore the actual working state of photovoltaic modules, LX-PV31 is equipped with high-precision irradiance meters, environmental temperature and solar panel temperature sensors, which can synchronously collect environmental parameters, accurately record the lighting and temperature conditions during testing, and achieve synchronous correlation between IV test data and environmental data, providing complete data support for STC nominal parameter conversion, power generation efficiency analysis and PR value calculation. At the same time, the equipment has a high-voltage isolation design, built-in overvoltage, overcurrent, and reverse connection protection functions, ensuring the safety and stability of the testing process; Support component barcode scanning and recognition to achieve intelligent management of components; The internal memory can store over 2000 sets of test data, supporting one click export for easy data archiving, analysis, and report generation.

With excellent performance and convenient operation, the LX-PV31 portable IV tester has a wide range of application scenarios, covering multiple fields such as photovoltaic power plant construction acceptance, daily operation and maintenance, fault diagnosis, third-party testing agency certification, photovoltaic module production quality inspection, and scientific research unit experimental research. In large ground power stations, string IV testing can be quickly completed to promptly detect issues such as power attenuation, hidden cracks, and hot spots; In distributed photovoltaic projects, portable bodies can adapt to complex scenarios such as household use and commercial rooftops, and flexibly complete component performance sampling; In operation and maintenance inspections, the efficient detection mode significantly shortens operation time, reduces operation and maintenance costs, and helps improve the quality and efficiency of power plants.

Suzhou LAILX always adheres to the development philosophy of "technological innovation, quality first, and service-oriented", establishing a full process quality control system from product research and development, production and manufacturing to after-sales service. As one of the core products of LAILX, the LX-PV31 portable IV tester has undergone rigorous environmental testing and extensive on-site verification. Its performance is stable and reliable, and it can adapt to harsh outdoor environments such as high temperature, low temperature, humidity, and sand and dust, meeting the long-term needs of field operations. At the same time, LAILX provides customers with one-stop services, including product installation and debugging, operation training, technical support, and after-sales maintenance.
