This 1.2MWh/600kW all-in-one C&I energy storage cabinet utilizes Lithium Iron Phosphate (LFP) battery technology, featuring scalable capacity from 1MWh to 10MWh with 500kW rated power output. The pre-engineered container solution (20/40ft options) integrates PCS, BMS, EMS, PV/diesel generator interfaces, fire suppression, and liquid-cooled thermal management systems, supporting multi-cabinet parallel scalability. Intelligent operation enables cell-level monitoring via BMS/EMS integration, supporting multiple operational modes including peak-valley arbitrage, demand charge management, and backup power, with real-time performance visualization through a remote O&M platform. Designed with dual safety redundancy featuring aerosol fire suppression and liquid cooling thermal control, the system meets UL1973/CE/IEC62619 certifications and IP54 protection standards for industrial load peak-shaving, renewable energy curtailment reduction, EV charging power buffering, and emergency backup
