Utility-Scale Power in a Standard 20ft Container
The UE 20ft Liquid Cooling BESS Container 1000kW/2170kWh is a highly integrated, liquid-cooled energy storage solution designed for large commercial, industrial, and utility-scale applications. Delivering 1MW of power and 2.17MWh of capacity, it features a hybrid cooling system, string-based battery management, and dual-layer fire protection. Pre-installed and pre-tested, it ensures rapid deployment and maximum ROI.
The Future of Large-Scale Energy Storage
The UE BESS Container (Model: BK1-2170L) represents the pinnacle of energy density and integration. Designed for projects requiring megawatt-scale power, this all-in-one solution integrates the 3S system (BMS, EMS, PCS), cooling, fire protection, and AC combiner into a single standard 20ft container.
Engineered for Efficiency & Reliability At the core is a hybrid cooling system: the battery packs utilize advanced liquid cooling to maintain temperature uniformity within 3°C, while the PCS uses forced air cooling. This dual approach ensures high efficiency and extends battery life. The string-based solution means each battery cluster is managed independently, preventing single-point failures and maximizing system uptime.
Safety You Can Trust Safety is paramount in large-scale storage. This container features a comprehensive dual fire suppression system combining aerosol and water spray, providing the highest level of protection against thermal runaway. Certified to UL9540A and IEC62619, it meets the strictest global safety standards.
Fast Deployment, Low Cost Unlike traditional site-built systems, the UE BESS Container is pre-tested and pre-installed at the factory. This significantly reduces on-site construction time, lowers installation costs, and shortens the lead time to operation. Whether for peak shaving, renewable integration, or microgrids, this container delivers immediate value.
