Relying on a large-capacity centralized energy storage system, it provides integrated support for source-grid-load-storage for medium and large-scale scenarios. By smoothing out the output fluctuations of wind and solar power, it realizes the grid integration and accommodation of large-scale green electricity, participates in peak shaving, frequency regulation, and backup power services, alleviates peak grid pressure, and defers expansion investment. The equipment supports long-term stable and efficient operation under harsh conditions such as high temperature, high altitude, wind and sand, salt spray, and low temperature. Paired with a cloud O&M platform, it realizes full lifecycle status monitoring and intelligent scheduling, providing users with stable, economical, and efficient energy storage services.
