Maximum Power, Optimized Capacity.

The UE 125kW BESS Cabinet 261kWh delivers the highest power output in our standard cabinet series. Designed for demanding commercial applications, it combines 125kW of power with 261kWh of storage in a compact 1.4m² footprint. With liquid cooling, 8,000+ cycle life, and IP55 outdoor protection, it's the perfect solution for facilities requiring high power delivery with moderate energy storage.

High Power Meets Smart Design

The UE BESS Cabinet 125kW/261kWh is engineered for commercial facilities that prioritize power output. With the highest 125kW AC output in our standard cabinet series, it's ideal for facilities with heavy loads, rapid charging needs, or demanding peak shaving requirements.

Why Choose 125kW? The 125kW output allows you to:

  • Support larger commercial loads and multiple simultaneous equipment
  • Reduce or eliminate the need for parallel inverters
  • Provide rapid response for grid services and frequency regulation
  • Handle high-power applications like EV charging or industrial machinery

Efficient Thermal Management The system features optimized in-PACK duct design for liquid cooling, ensuring high-efficiency heat dissipation with minimal energy consumption. This maintains cell temperature differences within 3°C, extending battery life by 20-30% compared to standard air-cooled systems.

Built for Real-World Conditions With an IP55 rating, C4 anti-corrosion coating (C5 optional), and operating range from -25°C to 55°C, this cabinet thrives in outdoor environments. The integrated aerosol fire suppression system and comprehensive safety certifications (UN38.3, IEC62619, UL9540A) ensure 24/7 protection.

Smart & Scalable The modular design supports easy parallel expansion. Compatible with major hybrid inverter brands and featuring Modbus TCP/IP communication, integration is seamless. With 89% round-trip efficiency and ≤75 dB noise level, you get quiet, efficient operation.

FAQS

Q :

What makes the 125kW model different?

A :

The 125kW version provides the highest power output in our standard cabinet series, making it ideal for facilities with heavy loads or rapid power response needs. It's perfect when you need more power than capacity.

Q :

Can I use this for EV charging stations?

A :

Yes. The 125kW output is excellent for buffering power at EV charging stations, allowing you to charge multiple vehicles simultaneously without overloading the grid connection.

Q :

How long can it provide backup power?

A :

At full 125kW output, you get approximately 2 hours of backup. At partial loads (e.g., 50kW), runtime extends to 5+ hours. Actual duration depends on your specific load profile.

Q :

Is the system expandable?

A :

Absolutely. The modular design supports parallel connection of multiple cabinets. Start with one unit and scale as your energy needs grow.
