SNEC PV+ 2025: PV-storage integration, smart storage for the future, successfully concluded

On June 11, the 18th (2025) International Solar Photovoltaic and Smart Energy (Shanghai) Conference was grandly opened at the National Exhibition and Convention Center. More than 3,000 energy companies from around the world presented their latest technological achievements, and more than 500,000 professional visitors from home and abroad visited the exhibition, fully demonstrating the vigorous vitality of the photovoltaic and energy storage industry. This exhibition attracted three representative international visitors: delegations from European economies such as Germany, France, Spain, and Italy, professional purchasing groups from mature markets such as the United States, Japan, and South Korea, and representatives from emerging industrial countries such as the Middle East, India, Southeast Asia, and South America. "Light chasers" in the new energy field from more than 90 countries and regions around the world gathered in Shanghai to witness this annual industry event that integrates technology display, business docking, and industry exchanges. As a senior exhibitor at the SNEC exhibition for more than ten years, Anhui Jinli has always adhered to the development concept of "protecting users from lightning". At this exhibition, it brought full-scene photovoltaic storage products, smart lightning protection overall solutions and cutting-edge technological achievements to the 6.1H-D220 booth. The full-chain technology display from photovoltaic energy storage system to intelligent lightning protection system attracted many professionals in the field of photovoltaic energy storage and international merchants to stop and watch. Industry enthusiasts from many parts of the world conducted in-depth consultations on product performance, technical applications and scenario solutions, and the on-site communication atmosphere was warm. Anhui Jinli has won wide recognition with its innovative technology and professional services. DC2000V Din rail SPD and PCB type SPD With the iterative innovation of photovoltaic technology and material science, the battery conversion efficiency, material insulation level and manufacturing process have achieved leapfrog development, creating technical conditions for the improvement of system voltage level. In this context, the power density of photovoltaic systems has been significantly optimized, driving the continuous decline of life cycle costs. At present, the technical maturity of key electrical equipment such as switchgear, transmission cables, and lightning protection devices supporting 2000V systems has met the needs of engineering applications, but the update of the industry standard system lags behind, which objectively restricts the large-scale promotion of 2000V photovoltaic power station systems. In the field of lightning protection technology, our company has built a mature SPD product application system that can accurately match the surge protection needs of DC2000V photovoltaic systems. By integrating intellig...

Hot early summer, enjoy sports: Jinli Electric's dynamic team-building trip
On the sunny day of May 6, Anhui Jinli Electric held a wonderful team-building activity with the theme of "Hot early summer, fun sports" at "My Gardener" in Feixi. This activity perfectly integrated fun sports with corporate culture, allowing employees to enjoy the joy of sports and also showing the unique corporate charm of Jinli Electric. Trolleybus: Keeping the same frequency and reaching the destination During the activity, the team members walked side by side with balloons on their heads. Only by keeping in step and cooperating throughout the process can mistakes be avoided. This is just like Jinli Electric's mission - in the face of complex technical challenges, only by resonating in the whole process of R&D, production, and after-sales can the promise of "protecting users from lightning intrusion" take root. Team Pyramid: Every goal is a "star" held together The 14 balls need to be placed on the top of the tower by the team pulling the ropes, just like every order and every goal ofJinli Electric, which requires the cooperation of marketing, technology, R&D, business, product and other departments. "Every ball on the top of the tower is the cornerstone of our vision of 'creating the world's best lightning protection brand'." Fun competition: Sports activate vitality, health is fighting power The "shouting in unison" of land dragon boat racing, the "quick eyes and quick hands" of Tetris, the "juggling race" with stars centering on the moon... Every event of the fun sports meeting allows employees to release stress through running and collaboration. With vitality as the sail, set sail towards "the best in the world" The setting sun draped a golden coat over "My Gardener", and this team building full of laughter and insights came to an end. But Jinli people's adherence to "safety" and "health" continues - just as the slogan shouted by everyone at the end of the event: "Hot early summer, enjoy sports; Jinli lightning protection, we are the best!" In the future, Jinli Electric will continue to use "original technology" as its paddle and "healthy team" as its sail to forge ahead on the journey of "creating the world's best lightning protection brand". Because we firmly believe that when every Jinli person becomes a guardian of safety and a practitioner of health, those "pyramid tips" that are jointly lifted up will eventually illuminate the sea of stars in the field of lightning protection.
