Product Description

Lithium Battery System

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.

Container Connection

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.

 

 

1MWH Battery Container

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.
