In the wave of large-scale development of the global photovoltaic industry, the power generation performance testing of photovoltaic strings is the core link of power station design, acceptance, and operation and maintenance. Traditional IV testing equipment is difficult to meet the mobile detection needs of complex scenarios such as mountains and rooftops due to its large size, complex operation, and poor outdoor adaptability. Suzhou LAILX New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of photovoltaic testing for many years. With its independent research and development strength and technological accumulation, it has launched the LX-PV32 portable IV tester, which solves industry testing problems and injects hardcore power into the high-quality development of the photovoltaic industry with its core advantages of precision, convenience, and full scene adaptation.

As a professional equipment specially designed for testing 1500V photovoltaic string, LX-PV32 has achieved multiple breakthroughs in technical performance. The device supports 1500VDC photovoltaic string system testing, with a current range of up to 20A. It can accurately measure more than 20 key parameters such as I-V curve, P-V curve, short-circuit current, open circuit voltage, peak power, fill factor, conversion efficiency, etc., fully covering the performance testing needs of photovoltaic strings. In response to the complexity of outdoor testing environments, the instrument is equipped with high-precision irradiance and temperature dual probes, which can synchronously collect environmental temperature, solar panel temperature, and irradiance data, accurately record the environmental status during testing, provide scientific calibration basis for testing results, and ensure that the data truly reflects the working characteristics of photovoltaic strings under natural light.

Portable design is one of the core highlights of LX-PV32. The device adopts an integrated lightweight architecture, paired with a 6.5-inch high-definition color LCD touch screen. The operation interface is simple and intuitive, supporting bilingual switching between Chinese and English. Non professionals can also quickly get started. Equipped with a high-capacity lithium-ion battery, it has a long-lasting battery life and can complete long-term outdoor operations without the need for an external power source, completely eliminating the dependence of traditional devices on mains electricity. The whole machine is highly portable, and can be easily carried by a single person to scenarios such as rooftop distributed power stations, mountainous and hilly power stations, and household photovoltaic projects, achieving "ready to test and inspection". Single block string detection can be completed in just 10 seconds, greatly improving the efficiency of operation and maintenance detection.

In terms of detection accuracy and stability, LX-PV32 has reached the industry-leading level. The equipment adopts high-precision capacitive/resistive load modules, with voltage measurement accuracy of 0.1V, current measurement accuracy of 0.001A, and testing accuracy of ± 0.5% ± 0.2V, which can accurately capture subtle performance differences of photovoltaic strings. At the same time, it has the function of STC nominal parameter conversion testing, which is suitable for over 95% of current photovoltaic panel specifications, and can automatically calculate the power generation efficiency and conversion rate of the panel; High voltage isolation design and intelligent cooling system effectively suppress outdoor electromagnetic interference and high temperature effects, ensuring stable operation of equipment in extreme environments ranging from -20 ℃ to 60 ℃, and eliminating data drift and false measurement problems.
In addition, LX-PV32 is equipped with an intelligent data management system that supports one click export of detection data, which can be quickly stored on mobile devices through a USB interface. Equipped with professional analysis software, it can analyze IV curves in high definition, generate standardized detection reports, and facilitate later data traceability and operation analysis. The device also has extended functions such as barcode scanning, 100 meter wireless communication, power generation irradiation monitoring, and PR value calculation, fully meeting the differentiated needs of different users such as power station operation and maintenance, third-party testing, and scientific research institutions.

From laboratory research and development to outdoor testing and optimization, LX-PV32 has undergone multiple rounds of rigorous testing, fully verifying its outstanding performance in precision, portability, and stability. As a core testing tool for the full lifecycle management of photovoltaic power plants, this equipment can assist power plant construction units in controlling construction quality, efficient inspection of performance hazards by operation and maintenance teams, and precise research on photovoltaic technology by scientific research institutions, providing solid guarantees for improving the quality and efficiency of photovoltaic power plants and extending their service life.

In the future, LAILX in Suzhou will continue to focus on innovation in photovoltaic detection technology, guided by user needs, continuously optimize product performance, enhance product competitiveness, and provide more efficient, accurate, and intelligent detection solutions for the global photovoltaic industry, helping the clean energy industry reach new heights.
