Wedoany.com Report-Apr. 15, JinkoSolar showcased its advanced SunTera G3 battery energy storage system (BESS) at the 13th Energy Storage International Conference and Expo (ESIE2025) held in Beijing last week. The unveiling highlighted the company’s commitment to delivering innovative energy solutions tailored for global markets.
The SunTera G3, encased in a standard 20-foot container, offers a rated capacity of 6.251 MWh. Designed for durability, it supports over 10,000 operational cycles and achieves a roundtrip efficiency exceeding 95%, ensuring optimal energy output throughout its lifespan. The system is built to perform reliably in diverse conditions, with certifications for IP55 ingress protection and C5 anti-corrosion standards. It can operate at altitudes up to 4,000 meters, making it suitable for challenging environments worldwide.
Wu Dianfeng, general manager of JinkoSolar’s storage division, emphasized the system’s focus on safety: “Safety is the bottom line in energy storage, and our core design philosophy. Unlike electric vehicles, where safety concerns often stem from collisions, storage systems are grid-connected, requiring far more stringent attention to electrical safety.” This approach underscores the company’s priority to meet rigorous safety standards for grid-integrated applications.
The SunTera G3 is engineered to enhance energy storage efficiency, supporting applications in various global markets. Its robust design ensures consistent performance, contributing to the stability and sustainability of energy systems. The system’s high cycle life and efficiency make it a valuable asset for large-scale energy projects, addressing the growing demand for reliable storage solutions.
JinkoSolar’s presentation at ESIE2025 in Beijing reflects its ongoing efforts to advance energy storage technology. The SunTera G3 aligns with the industry’s shift toward sustainable energy infrastructure, offering a solution that balances performance, safety, and adaptability. By introducing this system, JinkoSolar strengthens its position as a key player in the global energy storage market, supporting the transition to cleaner energy worldwide.
