According to Official Ammount @gJinkoSolar, on April 10th, ESIE2025, the 13th International Energy Storage Conference & Expo, grandly opened in Beijing. As a global leader in the integrated PV and energy storage field, JinkoSolar showcased its photovoltaic and energy storage smart energy solutions at the exhibition and launched its new generation of Blue Whale SunTera G3 6.25MWh battery energy storage system. This energy storage product, which embodies cutting-edge technology, has garnered significant attention since its release and is expected to officially begin global delivery in the fourth quarter of 2025, injecting new momentum into the global energy transition.
Through continuous exploration and in-depth research, the Jinko Blue Whale SunTera G3 6.25MWh battery energy storage system redefines new standards for energy storage products with its core of innovative technology. The system adopts a 20-foot standard container design, compatible with global markets, and has a rated capacity of up to 6.251MWh, meeting large-scale energy storage demands. With a cycle life of over 10,000 cycles and a cycle efficiency of over 95%, SunTera G3 significantly increases discharge capacity throughout its entire life cycle, providing a reliable guarantee for the energy transition. The system has an IP55 protection rating and a C5 anti-corrosion rating, and supports operation at altitudes up to 4,000 meters, adapting to various extreme conditions without fear of harsh environments.
In addition, the Jinko Blue Whale SunTera G3 builds an all-around protection system with "safety as the cornerstone," creating industry-leading safety standards through structural safety, electrical safety, and fire safety. In terms of structure, it features a unique five-level protection architecture from cell to system, supporting cell-level anomaly early warning, 2-hour fire resistance for the container, and equipped with system-level fire suppression gas, eliminating the spread of potential hazards. In terms of electrical safety, it adopts a three-level fuse technology to accurately cut off fault currents, combined with real-time cluster-level leakage detection to ensure stable and controllable current systems. In terms of fire safety, it achieves three levels of protection: pack-level fire suppression, container-level gas fire suppression, and container-level water fire suppression. From the microscopic cell to the macroscopic system, JinkoSolar uses progressively advanced safety technology innovations to build an indestructible defense network for energy storage systems, ensuring that technological innovation always operates on a safe track.
To achieve intelligent management of energy storage systems, the Jinko Blue Whale SunTera G3 uses digital technology as a link, building a smart operation and maintenance system covering the entire life cycle through a fully self-developed "end-domain-cloud" integrated architecture platform, empowering energy storage systems to be safer, more efficient, and more economical. Jinko has built an overall data security guarantee from the end to the cloud based on a cloud computing security system. Its information security management system meets the ISO27001 standard, and the JKOS security architecture complies with the IEC62443 standard. Currently, Jinko's cloud service deployment covers the globe, providing integrated and intelligent big data cloud services for domestic and international commercial and industrial, as well as large-scale energy storage projects.
With the accelerating global energy transition, energy storage technology is becoming a key force in promoting the adoption of clean energy and optimizing energy structures. The launch of Jinko Blue Whale SunTera G3 is not only a significant breakthrough for JinkoSolar in the energy storage field but also a fulfillment of its commitment to a "zero-carbon future." In the future, JinkoSolar will continue to deepen technological innovation and application scenarios, providing global users with more efficient and sustainable energy storage solutions through a more intelligent and safer energy storage ecosystem.
