Product Description

The outdoor liquid cooling energy storage container equipped with an integrated outdoors container, with below main components:
>The system consists of liquid-cooled battery pack, which is equipped with 314Ah cells. It features a 1P48S configuration and employs liquid cooling to maintain a temperature difference among the cells within 3 ℃, thereby enhancing operational efficiency and extending the service life of the battery.
>9 modular bidirectional power converters (PCS), The container includes 2 PCS cabinets, with a total of 9 125kW PCS. Each PCS is connected to one battery cluster and controls the charging and discharging of this battery cluster.
>1 vertical 40kW liquid cooling unit and 1 aerosol fire extinguishing system to ensure the system work normally and safely in various environments.
>1 dynamic environment monitoring system and 1 container-level EMS control system.

System Wiring Connection
Modular Design: 9 × 125kW PCS units form a total 1125kW system, allowing flexible scalability and enhanced redundancy.
DC-side Parallel Configuration: Multiple battery clusters are connected in parallel to each PCS; battery consistency and cluster-level protection are essential.
Centralized AC Interconnection: All PCS units converge at the Grid-connected Cabinet, simplifying control, metering, and protection.
Typical Applications: Commercial & industrial (C&I) storage, PV-storage-charging integration, and sites requiring backup power capability.
