Maximize Energy Efficiency in Just 1.4m².
Maximize Energy Efficiency in Just 1.4m². The UE BESS Cabinet is a fully integrated, liquid-cooled energy storage solution designed for C&I applications. Combining 75kW AC output with 216kWh LFP storage, this unit features IP55 outdoor protection, support for up to 250kW PV input, and a cycle life of over 8,000 cycles. It’s the ultimate plug-and-play solution for reducing energy costs and ensuring power reliability.
The Smarter Way to Store Energy
The UE BESS Cabinet (Model: FL1-261L Series) redefines commercial energy storage by integrating complexity into simplicity. Instead of managing separate components, you get a single, robust unit that handles everything from energy storage to thermal management.
Engineered for Longevity & Safety At the core of this system are high-performance 314Ah LiFePO4 cells, rated for ≥ 8,000 cycles. But capacity is nothing without control. Our proprietary Liquid Cooling + Forced Air Cooling system actively manages battery temperature, keeping the variance within 3°C. This precision not only prevents hotspots but significantly extends the usable life of your investment. Housed in an IP55-rated enclosure with C4/C5 anti-corrosion coating, this cabinet is built to withstand harsh outdoor environments, from freezing winters to scorching summers (-25°C to 55°C).
Solar-Ready & Scalable Designed for the modern grid, the cabinet supports a massive 250kW PV input, allowing you to pair it with large solar arrays to maximize self-consumption and reduce peak demand charges. The modular design means you aren't locked in; as your energy needs grow, you can easily parallel connect multiple cabinets to expand capacity. With a 90% Round Trip Efficiency and compatibility with major hybrid inverter brands, the UE BESS Cabinet ensures you get the most power for your money.
