Introduction
Commercial & Industrial Energy Storage System|Liquid-cooled Integrated Energy Storage Cabinet
1. Product Overview
The 125kW-261kWh Liquid-cooled Integrated Energy Storage Cabinet is a turnkey commercial and industrial energy storage system designed for factories, industrial parks, commercial buildings and renewable energy projects.
With 261kWh battery capacity and 125kW rated power in a single outdoor cabinet, the system integrates all key energy storage components including PCS, lithium iron phosphate battery modules, BMS battery management system, liquid cooling thermal management system, fire protection system and EMS energy management system.
The cabinet is equipped with built-in PV access interface and STS static transfer switch, supporting grid-connected operation, off-grid backup power and PV + energy storage applications.
Compared with traditional air-cooled energy storage solutions, the liquid cooling system provides more uniform temperature control, lower temperature difference between battery cells and improved reliability during long-duration high-power charging and discharging operations.
Designed with an IP54 outdoor protection rating, the integrated energy storage cabinet can be directly installed outdoors without additional container rooms or complex infrastructure, significantly reducing project installation time.
It is widely used in:
- Industrial factory peak shaving
- Commercial solar + storage projects
- EV charging station energy storage
- Microgrid systems
- Critical load backup power
