Maximum Capacity in a Standard 20ft Container
The 5MWh Liquid-Cooled BESS is our highest-capacity liquid-cooled battery energy storage solution. Designed for utility-scale and large C&I applications, it delivers an industry-leading 5.015MWh of energy storage in a standard 20ft footprint. With advanced liquid cooling, 8,000+ cycle life, and dual fire suppression, it provides unmatched energy density and safety for grid-scale projects.
The Ultimate in Energy Density
The UE BESS Container 5MWh (Model: TD1-5015L) represents the pinnacle of energy storage density. With a massive 5.015MWh capacity packed into a standard 20ft container, this system delivers the highest energy storage per square meter in our portfolio.
Engineered for Utility-Scale Applications This battery-only container is designed for demanding applications requiring massive energy storage:
- Grid-scale energy storage for load balancing and frequency regulation
- Renewable energy integration for solar and wind farms
- Large industrial facilities requiring extended backup power
- Microgrids needing substantial energy reserves
Superior Thermal Management The advanced liquid cooling system maintains cell temperature differences within 3°C across all 416 cells (12P416S configuration). This precision cooling is achieved through:
- Variable-frequency compressor that adapts to temperature conditions
- Optimized liquid cooling circuits for each battery pack
- Reduced fan usage for lower noise and energy consumption
The result is 20-30% longer battery life compared to air-cooled systems and significantly improved voltage consistency.
Comprehensive Safety Systems Safety is paramount at this scale. The container features:
- Dual fire suppression: Aerosol system + Water spray system
- IP55-rated enclosure (PACK IP65) for environmental protection
- C4 anti-corrosion coating (C5 optional for harsh environments)
- Comprehensive certifications: UN3536, IEC62619, IEC63056, IEC62477-1
Lower Operating Costs The liquid cooling design significantly reduces:
- Self-power consumption through intelligent temperature management
- Operating noise by minimizing fan usage
- Maintenance requirements with fewer moving parts
- Installation costs with pre-integrated systems
