1. Product Overview
The 125kW/241kWh Air-Cooled Integrated Power Cabinet is a cost-effective commercial and industrial energy storage system designed for factories, industrial parks, renewable energy projects and off-grid microgrid applications.
With 241kWh battery capacity and 125kW rated power, this outdoor integrated ESS cabinet combines PCS, lithium iron phosphate battery modules, BMS, air cooling thermal management system, fire protection system and EMS energy management system into one complete solution.
The system is specially optimized for PV + Storage + Diesel microgrid applications, enabling intelligent coordination between solar power generation, battery energy storage and diesel generators to achieve stable and reliable power supply in areas with limited or unstable grid access.
Compared with liquid-cooled energy storage systems, the air-cooled design provides lower initial investment, simpler maintenance and higher cost efficiency, making it an ideal choice for budget-sensitive C&I energy storage projects with moderate continuous charge and discharge requirements.
Multiple cabinets can be connected in parallel to expand capacity and build MW-level commercial energy storage systems.
