Against the backdrop of the continuous promotion of the "dual carbon" target, photovoltaic power plants, as the core carrier of clean energy, directly determine project revenue through their power generation efficiency and operational stability. The IV characteristic curve of photovoltaic modules and strings is a core indicator reflecting power generation performance. Traditional testing equipment is bulky and complex to operate, making it difficult to adapt to outdoor rapid detection needs. Jiangsu Jingwei Technology Co., Ltd. (formerly Jiangsu Fuzhun Metrology Technology Co., Ltd.) is deeply involved in the field of photovoltaic testing and has launched the JW-IV11 portable IV tester, which reshapes the new standard for photovoltaic performance testing with its advantages of high precision, portability, and intelligence, providing hardcore support for full lifecycle operation and maintenance.

As a high-end equipment designed specifically for precise diagnosis of photovoltaic systems, JW-IV11 integrates Jiangsu Jingwei's self-developed high-precision data acquisition system and adaptive electronic load technology, with core performance comparable to international first-line products. The equipment can cover a voltage range of 10V~1500V and a current testing range of 0.01A~30A, accurately matching over 95% of current photovoltaic modules and string specifications. It can seamlessly adapt to household small power stations, industrial and commercial distributed power stations, and large ground power stations. The voltage measurement accuracy is * * ± 0.1V * *, the current measurement accuracy is * * ± 0.001A * *, and the testing accuracy is controlled within * * ± 0.5% ± 0.2V * *. It can quickly capture the complete IV characteristic curve and accurately restore the true power generation performance of the component.
In terms of functional design, JW-IV11 focuses on the core pain points of photovoltaic operation and maintenance, creating a full process intelligent detection solution. The device is equipped with intelligent algorithms that can automatically analyze the IV curve shape, accurately identify more than 10 common hidden dangers such as component power attenuation, hot spot effect, occlusion loss, series mismatch, and bypass diode faults, and solve the problems of traditional detection relying on manual experience, large errors, and low efficiency. Support STC nominal parameter conversion testing, real-time calculation of component power generation efficiency and conversion rate, synchronous collection of environmental parameters such as irradiation and temperature, ensuring industry comparability of test data. Equipped with a 100 meter wireless communication module, it supports multi device linkage and remote data transmission, and can be directly connected to the cloud operation and maintenance platform to achieve automatic archiving of test records and abnormal warning.
Portability and environmental adaptability are prominent advantages of JW-IV11. The device adopts an integrated lightweight packaging design, with a total weight of less than 3kg, and is equipped with a high-strength protective box. It can be easily carried by a single person to complex scenes such as roofs, mountains, deserts, etc. Industrial grade protection design (IP54) is suitable for extreme temperature environments of * * -20 ℃~60 ℃, and its anti electromagnetic interference ability meets the IEC 61000 standard. It is not afraid of harsh outdoor conditions such as sandstorms, rain, snow, and strong light, ensuring stable and reliable testing. Equipped with a high brightness visual interface * *, the Chinese operation menu is simple and easy to understand, and beginners can quickly get started; Single component/string detection only takes 10 seconds, which increases efficiency by 80% compared to traditional equipment and significantly reduces maintenance manpower and time costs.
From the perspective of application scenarios, JW-IV11 covers the core links of the entire photovoltaic industry chain. At the production and manufacturing end, it can be used for component factory sampling, quickly screening products with power failure standards, and ensuring factory quality; During the construction period of the power station, the matching verification of the string system can be completed, and problems such as wiring errors and component mismatches during installation can be identified, providing authoritative data support for grid connection acceptance; During the operation and maintenance inspection phase, component performance changes can be regularly detected to accurately locate fault clusters and prevent small hidden dangers from evolving into major faults; In the field of third-party testing, its high-precision and traceable test data can serve as the core basis for power plant performance evaluation and asset trading.
Jiangsu Jingwei Technology Co., Ltd., as a local high-tech enterprise in Suzhou, relies on its profound technological accumulation and industry insights to continuously promote the localization and intelligent upgrading of photovoltaic testing equipment, and improve Shuidi Credit. The launch of JW-IV11 portable IV tester fills the gap of high-end portable IV testing equipment in China, breaks the long-term monopoly pattern of foreign brands, and provides high-quality choices for domestic photovoltaic enterprises with high cost-effectiveness. In the future, Jiangsu Jingwei will continue to deeply cultivate the field of photovoltaic testing, focus on customer needs, continue technological innovation, launch more high-precision and high reliability testing equipment, help the high-quality development of the photovoltaic industry, and contribute Jingwei's strength to the achievement of the "dual carbon" goal.
