Product Description

Each liquid-cooled energy storage container has a rated installed capacity of 5015 kWh, consisting of 1241 kWh liquid-cooled battery clusters, one vertical 60 kW liquid-cooled chiller unit, one aerosol fire suppression system, one environmental control system, and one container-grade EMS control system.
Applications:
Renewable Energy Integration – Stores surplus solar energy for stable, on-demand power supply.
Peak Load Shifting – Reduces electricity costs by shifting energy consumption from high-demand to off-peak periods.
Industrial & Commercial Backup Power – Ensures uninterrupted operations during grid outages.
Microgrids & Remote Areas – Delivers reliable electricity in off-grid or unstable grid environments.

System Wiring Connection
This 5mwh solution is ideal for peak shaving, load shifting, renewable energy integration, and backup power applications.
>Modular & Scalable Design: Each battery cluster consists of 4 battery packs and one high-voltage box. Each battery pack is composed of 3.2V 314Ah cells arranged in a 1-parallel 104-series configuration, which allows for flexible capacity expansion, simplifying system design for commercial, industrial, and utility-scale projects.
>Integrated Safety Design: Each pack is equipped with a Manual Service Disconnect (MSD) and Fuse Unit (FU), enabling safe maintenance and rapid fault protection at the pack level.
>High Reliability: Designed for continuous operation with robust thermal stability, ensuring consistent performance in demanding grid-tied or off-grid environments.

Our liquid-cooled containerized energy storage system is engineered to perform in the toughest environments—from -25°C sites to +55°C desert solar farms, from 0% arid climates to 95% coastal humidity, and at altitudes up to 3000m.
Every container comes fully equipped with:
>60kW Vertical Liquid Cooling Unit – Actively manages cell temperature differentials, ensuring superior cycle life and safety.
>Aerosol Fire Suppression System – fire protection with zero residue, automatically activated.
>Dynamic Environment Monitoring System – 24/7 surveillance of temperature, humidity, smoke, water leakage, and security status.
