JW-IV13 portable IV tester from Jingwei Technology: accurately empowering efficient operation and maintenance of photovoltaic power plants


In the current rapid development of the global photovoltaic industry, precision and efficiency in power station operation and maintenance have become the core demands of the industry. Jiangsu Jingwei Technology Co., Ltd. is deeply involved in the field of photovoltaic testing and has launched the JW-IV13 portable IV tester. With lightweight design, high-precision testing capabilities, and intelligent analysis functions, it provides a one-stop solution for performance testing and fault diagnosis of photovoltaic modules and strings, helping photovoltaic power plants improve operation and maintenance efficiency and ensure power generation revenue. IV power detector


As the core equipment for the operation and maintenance of photovoltaic power plants, the JW-IV13 portable IV tester focuses on the efficient detection needs on site. It adopts high-precision digital sampling technology and dynamic electronic load technology, which can quickly capture the complete IV characteristic curve of photovoltaic strings, accurately analyze key parameters such as short-circuit current, open circuit voltage, and maximum power point, and the detection range covers components and strings within 1500V, adapting to the voltage level requirements of mainstream photovoltaic power plants. The device is equipped with intelligent algorithms that can perform multi-dimensional deep analysis of IV curves, accurately diagnose complex problems such as component power attenuation, hot spot effect, occlusion loss, series mismatch, bypass diode faults, and abnormal line connections, avoiding the drawbacks of traditional detection methods such as missed or false detections, and providing accurate fault location basis for operation and maintenance personnel.


JW-IV13 has achieved a breakthrough upgrade in portability and outdoor adaptability design. The whole machine adopts a lightweight integrated design, matched with an industrial grade protective chassis, which has dustproof, shockproof, and moisture-proof characteristics, and can adapt to complex outdoor environments such as mountains, deserts, and coastal areas. The device is equipped with a high brightness outdoor readable touch screen, which is clearly visible under strong light. It is paired with a user-friendly operation interface, supports bilingual switching between Chinese and English, and can start the detection process with one click. Single component or string detection can be completed in just 10 seconds, and can be operated by a single person with one hand, greatly improving on-site inspection efficiency. At the same time, the built-in high-energy density lithium battery has a long endurance that meets the needs of all day field operations, without frequent charging, and is suitable for multi scenario operations such as remote power stations and distributed rooftop power stations.


Intelligence and dataization are the core advantages of JW-IV13. The device is equipped with an AI assisted diagnostic system, which can automatically generate a structured detection report after the detection is completed, clearly marking the parameter data, fault type, and location. It supports local data storage and one click export for easy traceability analysis in the later stage. At the same time, it has cloud data synchronization function, which can upload detection data to the platform, realize remote data viewing, operation and maintenance cooperation, and equipment management, and help photovoltaic power plant operation and maintenance mode transform towards digitalization and intelligence. In addition, the device supports multi scenario adaptation and can be used for inspection of photovoltaic power plant modules upon arrival, regular performance testing, fault diagnosis, engineering acceptance, and third-party testing agency evaluation, covering the full lifecycle testing needs of photovoltaic modules.


Jiangsu Jingwei Technology has always been driven by technological innovation, relying on its strong research and development capabilities and rich industry experience to create high-quality testing equipment, Shuidi Credit, that meets the needs of the domestic photovoltaic market. The launch of the JW-IV13 portable IV tester fills the market gap in lightweight and high-precision IV detection equipment. With its core advantages of precise detection, portability, efficiency, and intelligent analysis, it has become a powerful assistant for photovoltaic power plant operation and maintenance personnel. In the future, Jingwei Technology will continue to deepen its research and development of photovoltaic detection technology, continuously optimize product performance, launch more innovative products that meet industry needs, and safeguard the high-quality development of the global photovoltaic industry, helping to steadily promote the "dual carbon" goal.
