Against the backdrop of the continuous promotion of the dual carbon strategy, the scale of the domestic photovoltaic industry continues to expand, and various ground power stations and distributed photovoltaic projects are blooming everywhere. Power station operation and maintenance, performance testing, and fault diagnosis have become key links to ensure the profitability of photovoltaic power generation. As the core means of evaluating the operation status of photovoltaic modules and strings, IV characteristic testing can intuitively reflect the power generation performance of equipment. Jiangsu Jingwei Technology is based on the actual needs of the industry and strives to create the JW-IV12 portable IV tester. With leading technology, excellent practicality, and stable performance, it provides reliable assistance for photovoltaic full scene detection work and promotes photovoltaic operation and maintenance towards refinement and intelligence.

During long-term operation, photovoltaic modules are prone to problems such as power attenuation, hot spots, diode damage, and poor line contact. These faults can directly reduce power generation efficiency, and traditional manual troubleshooting methods are inefficient and difficult to accurately locate the root cause of the problem. The JW-IV12 portable IV tester adopts advanced high-frequency sampling technology and adaptive load control scheme, which can fully capture the IV characteristic curve of photovoltaic string in a short time, synchronously calculate multiple core parameters such as open circuit voltage, short-circuit current, maximum power, fill factor, internal resistance, etc. The measurement data accuracy is at the forefront of the industry, providing solid data basis for technicians to analyze equipment status. The equipment is equipped with independently developed intelligent analysis algorithms that can automatically identify various common faults based on curve shapes. Whether it is power station completion acceptance, daily inspection, or energy efficiency evaluation of old equipment and difficult fault maintenance, it can quickly identify the problem, significantly reduce detection time, and lower operation and maintenance costs.
In response to the fact that photovoltaic testing is often carried out outdoors, this equipment takes into account both portability and environmental adaptability in its structural design. The whole machine adopts a lightweight integrated design, with a small size and portable grip. It is equipped with a dedicated protective box, and can be transported and operated by a single person without the need for multiple people to cooperate, greatly improving the efficiency of field operations. The equipment adopts industrial grade components, supports wide temperature operation, can work stably in the environment of minus 20 ℃ to 60 ℃, and has the ability to prevent dust, moisture, and electromagnetic interference. Complex scenes such as mountain, mudflat, plant roof, and water surface photovoltaic can be used normally, without fear of changing outdoor climate and site conditions.
In terms of operation and data management, JW-IV12 fully considers the operating habits of different users and is equipped with an outdoor high brightness touch display screen. The screen is still clear in strong light environments, and the layout of the all Chinese operation interface is simple with clear logic. Zero basic personnel can operate independently with simple guidance. The device is equipped with a large capacity lithium battery, which has excellent endurance performance and can meet continuous testing work for a whole day. It also supports real-time data storage and classification management. The data can be exported to the computer through both wired and wireless methods. The supporting analysis software can automatically generate standardized testing reports, making it convenient for enterprises to establish equipment testing files and achieve data traceability and replay. The addition of Bluetooth wireless transmission function also conforms to the trend of digital development in the photovoltaic industry, realizing remote synchronization of on-site data and making backend management more convenient.
Jiangsu Jingwei Technology has been deeply involved in the field of photovoltaic testing equipment for many years, always guided by market demand, insisting on technological innovation and quality control in parallel. From product research and development, component screening to complete machine assembly and factory testing, every process strictly follows industry standards to ensure the stable quality of each equipment. The JW-IV12 portable IV tester has broken through the technical barriers of high-end portable detection equipment. With its high cost-effectiveness advantage, it is widely used in various entities such as photovoltaic power station operation and maintenance enterprises, component manufacturers, and new energy research institutions. After extensive field application verification, it has received unanimous praise from the market and customers.
The photovoltaic industry is steadily moving towards a stage of high-quality development, and efficient, accurate, and intelligent detection equipment is an important support for industrial development. In the future, Jiangsu Jingwei Technology will continue to deeply cultivate the photovoltaic testing track, continuously optimize product performance, iterate and upgrade core technologies, and continuously improve the product system. With excellent products and thoughtful services, we assist major photovoltaic projects in stable operation, improve overall power generation efficiency, and work together with industry colleagues to promote the healthy development of the photovoltaic industry, fulfilling our corporate responsibility for achieving the national dual carbon goals.
