Maximum Capacity, Extended Runtime.
The UE Liquid Cooling BESS Cabinet 100kW/418kWh is our highest-capacity all-in-one energy storage solution. Delivering 418kWh of energy storage in just 2m², it's designed for facilities requiring extended backup times and large-scale energy shifting. With liquid cooling, 8,000+ cycle life, and IP55 outdoor protection, it provides exceptional value for demanding C&I applications.
When You Need More Energy Storage
The UE BESS Cabinet 100kW/418kWh is engineered for facilities that demand substantial energy storage capacity. With 418kWh of usable energy, this cabinet provides nearly double the storage of our 216kWh models, making it ideal for extended backup, large-scale load shifting, and microgrid applications.
Why Choose 418kWh? The massive 418kWh capacity allows you to:
- Store excess solar energy for overnight use
- Provide extended backup power for critical loads (8-12+ hours)
- Perform large-scale peak shaving for facilities with high demand charges
- Support microgrid operations with renewable integration
Advanced Thermal Management The system features pack-level liquid cooling with optimized in-PACK duct design. This ensures uniform temperature distribution across all 416 cells (1P416S configuration), maintaining temperature differences within 3°C. The result is enhanced cell consistency, improved safety, and extended battery life.
Flexible Voltage Options Unlike standard cabinets, the 418kWh model offers three voltage configurations:
- 400V for standard commercial applications
- 690V for industrial facilities
- 800V for high-voltage systems and future-proofing
This flexibility allows you to match the system to your specific infrastructure requirements.
Built for Long-Term Value With 8,000+ cycles at 100% depth of discharge and 89% round-trip efficiency, this cabinet delivers exceptional long-term performance. The modular design supports easy parallel expansion, and the 2m² footprint maximizes energy density per square meter.
