-Deepen technical collaboration and build a new benchmark for the integration of lightning protection and new energy On the morning of March 7, the unveiling ceremony of the "Jinli-Sineng Joint Laboratory" jointly built by Anhui Jinli Electric Tech. Co., Ltd. and Sineng Electric Co., Ltd. was grandly held at the Jinli Electric headquarters. The general manager and team representatives of Anhui Jinli Electric and the general manager and team representatives of Sineng Electric Wuxi R&D platform attended the ceremony to witness this important moment. -Focus on technology collaboration to solve industry pain points During the ceremony, Yang Zhen, general manager of Jinli Electric, and Wu Yaping, general manager of Sineng Electric's Wuxi R&D platform, spoke highly of the joint laboratory and reached a broad consensus on how to carry out further cooperation based on the joint laboratory platform in the next stage. The joint laboratory is not only a hardware testing platform, but also a bridge for more efficient communication between the R&D teams of both sides. It will lay the foundation for further strategic cooperation in the future. It is hoped that both parties will give full play to their respective advantages, use the joint laboratory as a carrier, output more technical results, and jointly overcome the lightning protection problems in new energy scenarios. Laboratory core capabilities and future planning The joint laboratory relies on the five core laboratory resources of Jinli Electric, including: Surge Protection Device Key Laboratory: Passed UL, TUV and other international certifications, and has full testing capabilities for GB/T and IEC standards; Standardization research platform: led the compilation of three national standards including the "Technical Specifications for Lightning Protection of Photovoltaic Building Integrated Systems". In the future, the laboratory will focus on three major directions: Lightning protection technology for new energy scenarios: research and development of customized lightning protection solutions suitable for photovoltaic power stations and energy storage systems; Intelligent detection system: Develop an AI-driven online monitoring platform for lightning protection equipment; Standardization output: jointly formulate new energy lightning protection industry standards and promote standardized application of technology. Those who walk alone go fast, but those who walk together go far In his summary, the general manager of Anhui Jinli Electric quoted the saying “Those who walk alone go fast, but those who walk together go far”, emphasizing the importance of win-win cooperation: “Today’s unveiling is a starting point, not an end point. The laboratory will become the ‘innovation engine’ of the technical teams of both sides, guided by the ‘dual carbon’ goals, and forge ahead in the vast sea of green energy!”

Photovoltaic DC 2000V technology refers to the technology of transmitting and applying the DC power generated by photovoltaic modules at a voltage level of 2000V in photovoltaic power generation systems. Its working principle is based on the basic principle of photovoltaic power generation, that is, using the photovoltaic effect. When sunlight shines on photovoltaic modules, photons interact with electrons in semiconductor materials, allowing electrons to obtain enough energy to generate electrons and holes that move in a directional manner under the action of the electric field to form DC power. In the photovoltaic DC 2000V system, through special circuit design and component selection, the low-voltage DC power output by photovoltaic modules is boosted and transmitted in the form of 2000V high-voltage DC power. In photovoltaic systems, the improvement of voltage levels is an important direction of technological development. From the early lower voltage levels, it has gradually developed to the 1500V system that is now widely used. At present, photovoltaic DC 2000V technology is gradually emerging. Compared with the traditional 1000V and 1500V systems, photovoltaic DC 2000V has significant advantages. In theory, higher voltage can effectively reduce the current, thereby reducing the resistance loss during the transmission process and improving the overall efficiency of the system. From the perspective of voltage level, 2000V is significantly higher than 1500V and 1000V. In terms of power transmission, according to the power formula P = UI (where P is power, U is voltage, and I is current), under the same power transmission requirements, the higher the voltage, the smaller the current. According to Joule's law Q = I²Rt (where Q is heat, i.e., lost energy, I is current, R is resistance, and t is time), the reduction in current will greatly reduce the resistance loss in the line. Under the same line resistance and transmission time, the line loss of the 2000V system can be significantly reduced compared to the 1500V system. This can bring considerable economic benefits to large-scale photovoltaic power stations. In addition, the 2000V system also has certain advantages in equipment cost and floor space. Due to the reduction in current, thinner cables can be used, reducing the cost and weight of the cables, while also reducing the space required for cable laying and the difficulty of construction. At present, technologies such as artificial intelligence, digital twins, and cloud computing are constantly innovating, digital technology is deeply integrated with new energy system technology, and application scenarios are constantly enriched, achieving cost reduction and efficiency improvement throughout the photovoltaic life cycle. 2000Vplug-in SPDs used in combiner boxes,PCB type SPDs in inverters, line lightning arresters, and supporting monitoring terminals have emerged. Following the development trend of the industry,Anhui Jinli has m...
