With the large-scale and refined development of the photovoltaic industry, the operation and maintenance testing, engineering acceptance, and fault diagnosis of distributed photovoltaic power stations and centralized photovoltaic bases are facing new challenges. Traditional desktop IV detection equipment is bulky, cumbersome to operate, and has poor environmental adaptability, making it difficult to meet the rapid detection needs of outdoor sites. The industry urgently needs lightweight, high-precision, and intelligent portable detection equipment. In response to the pain points of on-site testing in the photovoltaic industry, Jiangsu Jingwei is deeply involved in the field of new energy testing and has independently developed and launched the JW-IV12 portable IV tester. With the core advantages of portable body, precise detection, fast calculation, and full scene adaptation, it reconstructs the IV curve detection system of photovoltaic modules, providing hardcore equipment support for improving the quality and efficiency of photovoltaic power plants and standardizing operation and maintenance.

Compared to traditional testing equipment, the JW-IV12 portable IV tester has achieved a dual breakthrough in both structural and technical aspects. The equipment adopts an integrated lightweight and integrated design, abandoning the complex wiring structure and bulky body of traditional equipment. The whole machine is compact and portable, and can be easily carried by a single person to independently complete a complete set of testing operations. It perfectly adapts to complex outdoor scenarios such as rooftop photovoltaics, mountain photovoltaics, and agricultural photovoltaic complementary power stations, completely solving the industry problems of difficult equipment handling, cumbersome deployment, and high collaboration costs among multiple people. The equipment is equipped with an industrial grade high-precision ADC analog-to-digital conversion chip, combined with a self-developed high-speed scanning algorithm, which can achieve millisecond level data acquisition. With a single detection, more than ten core parameters such as open circuit voltage, short-circuit current, maximum power, fill factor, and conversion efficiency of photovoltaic modules can be synchronously obtained. It can quickly draw accurate IV and PV characteristic curves, and the detection efficiency far exceeds traditional equipment.
In terms of detection accuracy, JW-IV12 adheres to industrial grade detection standards and adopts a four wire precision detection architecture, effectively avoiding detection errors caused by line resistance. The voltage and current testing accuracy has reached the top level in the industry. The device is equipped with an intelligent environment perception module that can collect real-time data on on-site lighting intensity, environmental temperature, component temperature, etc. It relies on professional STC standard working condition correction algorithms to automatically calibrate the detection data in complex outdoor environments to standard testing conditions. Even in low light and large temperature fluctuations such as cloudy days, early morning, and evening, it can still output accurate, stable, and traceable detection data with data accuracy comparable to laboratory desktop detection equipment, fully meeting the strict requirements of photovoltaic module quality inspection, power station acceptance, and efficiency evaluation.
To meet the all-weather outdoor work requirements, JW-IV12 is equipped with multiple humanized designs and safety protection systems. The device adopts a dual operation mode of touch screen and physical buttons, which can be smoothly operated under strong light outdoors and wearing work gloves. The 4.3-inch high-definition and high brightness display screen is not afraid of direct sunlight, and the data display is clear and intuitive. Equipped with a large capacity long-lasting lithium battery, it can support uninterrupted batch testing operations all day long when fully charged, without the need for frequent charging, and is suitable for long-term field inspection work. At the same time, the equipment integrates multiple protection functions such as overvoltage, overcurrent, short circuit, and reverse connection, effectively avoiding the risk of circuit faults during outdoor testing, ensuring the safety of equipment and operators, and adapting to various high and low voltage photovoltaic module testing scenarios.
At the level of data management and application, JW-IV12 has powerful intelligent data processing capabilities. The device can store tens of thousands of sets of detection data locally, supporting real-time data viewing, historical data tracing, curve comparison analysis, and accurate judgment of photovoltaic module power attenuation, performance abnormalities, hidden faults, and other issues. Simultaneously supporting USB wired and Bluetooth wireless dual-mode data transmission, it can quickly export detection data to computers and mobile devices. Equipped with professional data analysis software, it can automatically generate standardized detection reports, data curves, and statistical reports, greatly simplifying the later data sorting, archiving, and traceability processes, helping operation and maintenance personnel accurately formulate component cleaning, maintenance, and replacement plans, and reducing power station operation and maintenance costs.
At present, Jiangsu Jingwei JW-IV12 portable IV tester has been widely used in various scenarios such as photovoltaic power plant engineering acceptance, daily operation and maintenance inspection, old power plant efficiency evaluation, component factory quality inspection, scientific research experiment testing, etc. With stable performance, accurate detection, and convenient operation, it has been widely recognized by industry customers. In the future, Jiangsu Jingwei will continue to deepen its cultivation in the field of new energy detection equipment, focus on industry pain points and technological iteration, continuously optimize product performance, and create more high-precision, intelligent, and portable detection equipment to safeguard the high-quality, standardized, and efficient development of the photovoltaic industry.
