Against the backdrop of the continuous promotion of the "dual carbon" target and the steady expansion of the photovoltaic industry, the refined operation and precise fault diagnosis of photovoltaic power plants have become the core link to ensure power generation efficiency and reduce operating costs. Jiangsu Jingwei Technology Co., Ltd. is deeply engaged in the research and development of photovoltaic testing equipment. With solid technical accumulation and rich industry experience, it has launched the JW-IV11 portable IV tester. This device has the core advantages of high-precision measurement, intelligent analysis, and portable design, providing a one-stop solution for photovoltaic string performance testing and fault diagnosis, and helping photovoltaic power plants achieve efficient management throughout their entire lifecycle. IV power detector
As the core power generation unit of a power station, the current voltage (IV) characteristic curve of photovoltaic modules is a key basis for reflecting power generation performance and locating hidden faults. Traditional IV detection equipment often suffers from pain points such as insufficient accuracy, cumbersome operation, and poor environmental adaptability, making it difficult to meet the rapid detection needs in complex outdoor scenes. The Jiangsu Jingwei R&D team has targeted industry pain points with precision. The JW-IV11 portable IV tester is equipped with a high-precision data acquisition system and adaptive electronic load technology, which can quickly capture the complete IV characteristic curve of photovoltaic strings within 10 seconds, accurately measure key parameters such as open circuit voltage, short-circuit current, and maximum power point, with a measurement accuracy of up to ± 0.5% ± 0.2V, voltage measurement resolution of 0.1V, current measurement resolution of 0.001A, and is suitable for mainstream photovoltaic string detection needs within 1500V/30A, covering more than 95% of the market's photovoltaic panel specifications.
In terms of fault diagnosis capability, JW-IV11 relies on intelligent algorithms to deeply analyze the IV curve shape, accurately identifying hidden problems such as component power attenuation, hot spot effect, occlusion loss, series mismatch, bypass diode faults, insulation degradation, and connection abnormalities, breaking the limitations of traditional detection that can only identify explicit faults. The equipment is equipped with a professional analysis platform that can automatically compare theoretical parameters, generate in-depth diagnostic reports including fault types, locations, and severity, and provide optimization suggestions, greatly improving fault localization efficiency and reducing manual troubleshooting costs.
Portability and outdoor adaptability are the core highlights of JW-IV11. The equipment adopts industrial grade protection design, with a sturdy and wear-resistant shell that has dust-proof, moisture-proof, and impact resistant characteristics. It can operate stably in extreme temperature environments ranging from -20 ℃ to 60 ℃ and is suitable for complex photovoltaic power plant scenarios such as Gobi, desert, mountainous, and coastal areas. The whole machine is lightweight and compact in size, paired with a portable protective case, making it easy for one person to carry it to the testing site; Equipped with a high brightness outdoor visual touch screen, it is clearly visible under strong light, supports both Chinese and English operation interfaces, one click start detection, data export, and can be quickly mastered without professional training, balancing professionalism and usability.
In addition, JW-IV11 has strong data interconnection and expansion capabilities, supports Bluetooth wireless transmission, can achieve data synchronization within 100 meters, and with a dedicated APP, can remotely view detection data, IV curves, and diagnostic reports; Built in large capacity storage, capable of storing tens of thousands of sets of detection data, meeting long-term operation and maintenance data traceability needs. The equipment is widely used in photovoltaic power plant construction acceptance, regular performance evaluation, fault diagnosis, component quality sampling, and research and development testing scenarios. Whether it is a large-scale ground power plant, distributed photovoltaic system, or household photovoltaic project, it can provide reliable testing support.
As a benchmark product for domestic photovoltaic testing equipment, Jiangsu Jingwei JW-IV11 portable IV tester breaks the monopoly of imported equipment technology with its four core advantages of high precision, intelligence, strong adaptability, and easy operation, and reduces testing costs for photovoltaic enterprises with high cost-effectiveness. In the future, Jiangsu Jingwei will continue to focus on innovation in photovoltaic detection technology, continuously optimize product performance, launch more high-quality equipment that meets industry needs, and help China's photovoltaic industry develop towards high efficiency, intelligence, and refinement, injecting strong momentum into achieving the "dual carbon" goal.
