    SNEC PV Power Expo 2026 Concludes Successfully
    The 19th (2026) SNEC International Photovoltaic Power Generation and Smart Energy Conference & Exhibition (Shanghai) concluded successfully on June 5 at the National Exhibition and Convention Center (Shanghai). Each gathering in Shanghai serves as a pivotal platform for Anhui Jinli to showcase new products and technologies, connect with global clients, analyze industry trends, and forge collaborative opportunities; it also stands as powerful testimony to our deep commitment to the field of new energy safety protection and the steady strengthening of our brand. Grounded in the new landscape of industry development, Anhui Jinli remains steadfast in its core philosophy of "protecting users from lightning-related disruptions." At booth 6.1H-D665,Jinli Electricis showcasing a comprehensive range of products—including supporting equipment for solar-plus-storage applications across various scenarios and monitoring terminals—alongside integrated smart lightning protection solutions and a host of cutting-edge core technological achievements. Throughout the exhibition, the booth attracted significant interest and a steady stream of visitors. Industry peers and clients from both domestic and international markets visited to engage in in-depth discussions and consultations regarding core product performance, advantages in scenario adaptability, implementation technologies, and customized solutions. Focusing on High-Voltage Evolution | Full Series of DC 2000V SPDs Tailored for Next-Gen PV Systems Currently, the technology for core electrical equipment—such as switchgear, transmission cables, and lightning protection devices—designed for 2000V photovoltaic systems has matured sufficiently to meet the requirements for practical project implementation; however, the lag in updating industry standards has, to some extent, constrained the large-scale adoption and rollout of 2000V high-voltage photovoltaic power plants. Addressing industry pain points and essential market demands, Anhui Jinli has deeply cultivated the field of lightning protection technology, establishing a comprehensive and mature application system for high-voltage-rated Surge Protective Devices (SPDs). The company has developed a full series of surge protection products specifically designed for DC 2000V photovoltaic systems, precisely meeting the rigorous protection requirements of high-voltage PV power plants. Meanwhile, its mature series of board-mounted 1000V and 1200V surge protectors are fully compatible with standard photovoltaic system applications, enabling comprehensive coverage across both high- and low-voltage scenarios. Comprehensive Smart Protection | Smart Lightning Protection Systems Lead New Industry Trends Against the backdrop of the intelligent and digital upgrading of new energy power plants, traditional passive lightning protection methods can no longer meet the operational and maintenance needs of smart power plants. The smart lightning protection system innovatively dev...

  • Blazing a Trail, Rowing Toward the Future
    11/ May 2026
    Blazing a Trail, Rowing Toward the Future
    As spring gives way to summer, Jinli Lightning Protection’s first-half team-building retreat kicked off right on schedule. The entire team headed to Lujiang to embark on a one-day outdoor adventure themed: "Blazing a Trail, Rowing Toward the Future." Leaving behind the hustle and fatigue of work, we set out with light hearts—ready to enjoy a truly joyful and exhilarating team journey! In the morning, we gathered at the outdoor grounds of the Lujiang Gotion Hotel. Beneath a clear, boundless sky, we teamed up to tackle a series of fun-filled challenges. The Roman Catapult team exerts its collective strength, aiming at the target with seamless coordination. Archery Tag: A high-octane clash—where the interplay of offense and defense reveals true responsibility. Moving the yoga ball requires unity of heart and perfect synchronization; only by maintaining a consistent pace can we advance steadily. Every task demands a division of labor and mutual support; everyone fulfills their respective duties and cooperates fully, and amidst laughter and cheers, we engrave the very essence of "team" into our actions. In the afternoon, we arrived at the picturesque Jintang Lake Wetland Park. The azure waters mirrored the blue sky; and although the wind and waves were strong, they could not dampen everyone's enthusiasm. Under the guidance of professional instructors, we received comprehensive onshore training—covering everything from paddle grip and steering to forward and backward maneuvering—enabling everyone to quickly master the basics and take to the water for practice. Although the wind and waves were significant, and a few colleagues inadvertently fell overboard, no one showed the slightest hesitation; instead, they met these mishaps with laughter. Upon returning to shore, they quickly regrouped—their fighting spirit undiminished—remaining fully energized and completely committed to the activity! The Great Crayfish Challenge: Teams navigate the lake in kayaks, putting their keen eyesight and speed to the test as they compete to catch the greatest number of crayfish—a contest brimming with surprises and fun! Canoe & Kayak Round-Trip Sprint: Each team fields two vessels, with the entire crew working in perfect unison to cut through the waves. Amidst the splashing spray, they challenge the record for the fastest round-trip time—a true showcase of both speed and passion. The entire event was filled with joy and laughter, and before anyone knew it, it had turned into a lively water fight party; with water splashing everywhere and laughter ringing out continuously, everyone had a thoroughly enjoyable and happy time. As the event drew to a close, the various groups gathered in circles to debrief. Unity, vitality, positivity, perseverance, giving one's all, embracing challenges, fulfilling one's role—these resonant keywords represent not only the takeaways from the day but, more importantly, the very essence of the team. We understand that a truly great team is on...
