Product Description
Next-Generation Energy Storage in a Single Cabinet
The UE BESS Cabinet 80kW/216kWh represents the pinnacle of integrated energy storage technology. Designed for commercial and industrial applications, this all-in-one solution eliminates the complexity of traditional BESS installations by combining battery storage, power conversion, thermal management, and intelligent control systems into a single, compact enclosure.
Superior Battery Technology
At the heart of the system are premium 314Ah LiFePO4 (LFP) cells, configured in a 1P260S arrangement to deliver a nominal system voltage of 832V (range: 728-936V). These cells are engineered for longevity, providing over 8,000 charge-discharge cycles at 100% depth of discharge under optimal conditions (25±2°C). This translates to 15+ years of reliable service life, significantly reducing your total cost of ownership.
Advanced Thermal Management
Temperature uniformity is critical for battery performance and lifespan. Our hybrid liquid cooling + forced air cooling system actively manages thermal conditions across all battery modules, maintaining temperature differences within 3°C. This precision cooling not only extends battery life but also enables consistent high-power performance even in challenging ambient conditions from -25°C to 55°C.
Built for Harsh Environments
Unlike indoor-rated systems, the UE BESS Cabinet is engineered for outdoor deployment. The IP55-rated enclosure provides complete protection against dust ingress and low-pressure water jets from any direction. The C4 anti-corrosion coating (C5 optional) ensures durability in coastal or industrial environments. An integrated aerosol fire suppression system provides 24/7 protection, giving you peace of mind.
Solar Integration Made Simple
Maximize your solar investment with support for up to 250kW of PV input. The system features 10 independent MPPT trackers with a wide 150-950V operating range, allowing flexible solar array design and optimal energy harvest throughout the day. The 80kW AC output is ideal for medium to large commercial facilities, providing sufficient power for peak shaving, load shifting, and backup applications.
Smart & Scalable
The modular architecture supports easy parallel connection, allowing you to start small and expand as your energy needs grow. Compatible with multiple hybrid inverter brands and featuring Modbus TCP/IP communication, the system integrates seamlessly with existing energy management platforms. With a 90% round-trip efficiency, you get more usable energy from every kilowatt-hour stored.
