261kWh All-in-One Liquid Cooled ESS Cabinet | High-Efficiency Energy Storage Solution

Overview

Our 261kWh All-in-One Liquid Cooled ESS Cabinet integrates LFP battery modules, liquid cooling, PCS, and intelligent control into a compact cabinet. It simplifies installation, saves space, and meets demanding energy storage needs (peak shaving, load shifting, backup power) with advanced cooling and global safety/grid compliance.

Core Advantages

All-in-One Design: Integrates batteries, PCS, cooling, fire suppression, and communication for plug-and-play installation. Compact size (1,050*1,350*2,400 mm) fits diverse scenarios.
Advanced Liquid Cooling: Dual-mode (liquid + forced air) thermal management maintains optimal temperature (-25℃~55℃), extending cycle life to ≥ 8,000 cycles and ensuring stable performance in extreme environments.
High Safety & Compliance: Aerosol fire suppression and IP55 protection; compliant with global safety standards (UN38.3, IEC62619, UL9540A) and grid codes (EN50549, G99, VDE4105, etc.).
Superior Performance: 89% max round-trip efficiency, 125kW rated output, 100% depth of discharge. Cobalt/nickel-free LFP cells offer thermal stability and sustainability.
Intelligent Management: Modbus TCP/IP communication enables real-time monitoring and remote system adjustment for efficient operation.
