Jinko ESS has announced the delivery of 476MWh of its SunTera G2 5MWh liquid-cooled system as the first batch under a 1GWh PV+storage framework agreement signed with a major customer in northern Jiangsu. Designed to support distributed solar power plants, the project leverages an integrated “solar + storage” approach to improve renewable energy consumption and enhance regional energy structure and reliability.
To address the comprehensive needs of distributed PV projects in northern Jiangsu for safety, cost-efficiency and environmental adaptability, the SunTera G2 system features an industry-leading liquid thermal management system that keeps cell temperature differences within 2.5°C. It also includes five-layer protection across battery, module, rack, container and system levels, providing strong resilience against high humidity and temperature fluctuation. With a 94% RTE and lifecycle exceeding 8,000, the system is ideally suited for distributed PV stations that require stable and long-term energy storage operation, supporting the development of a clean, efficient and secure regional energy supply system.
Damon Duan, GM for Jinko ESS China, commented: “This marks a major step forward for Jinko ESS in scaling up user-side solar-plus-storage applications. As distributed energy becomes a pillar of future power systems, our 5MWh SunTera solution—designed with safety, intelligence and performance in mind—is emerging as a top choice. We will continue to push the boundaries of innovation to deliver smarter, more adaptable storage products for industrial, commercial and distributed customers alike.”
