High-Efficiency Energy Storage Solution for Commercial and Industrial Applications
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 including peak shaving, load shifting, and backup power with advanced cooling and global safety/grid compliance.
Designed for commercial and industrial applications, this cabinet solution offers a perfect balance of capacity, power, and footprint, making it ideal for space-constrained installations requiring reliable energy storage.
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.
Dual-mode (liquid + forced air) thermal management maintains optimal temperature (-25℃~55℃), extending cycle life to ≥8,000 cycles and ensuring stable performance.
Aerosol fire suppression and IP55 protection; compliant with global safety standards (UN38.3, IEC62619, UL9540A) and grid codes (EN50549, G99, VDE4105, etc.).
89% max round-trip efficiency, 125kW rated output, 100% depth of discharge. Cobalt/nickel-free LFP cells offer thermal stability and sustainability.
The system efficiently stores electricity from the grid or renewable sources and dispatches it on demand. The integrated management systems ensure safety, efficiency, and longevity under various operating conditions.
AC power is converted to DC to charge the LFP battery system at rates up to 125kW.
261kWh of energy is stored in LFP cells. The liquid cooling system maintains uniform temperature across the battery modules.
Advanced EMS and BMS monitor and control the system for optimal performance, safety, and grid interaction.
DC power is converted back to AC and can supply up to 125kW to the grid or local loads as required.
Shopping malls, offices, hotels for peak shaving, backup power, and energy cost reduction.
Stabilize power supply, mitigate grid fluctuations, and optimize energy use in manufacturing facilities.
Store surplus solar/wind energy, improve grid integration, and provide firm capacity.
Provide reliable backup power for areas with unstable grid supply or off-grid applications.
Ensure continuous power supply and protect critical equipment from outages and voltage fluctuations.
Provide frequency regulation, voltage support, and other ancillary services to the utility grid.
