A containerized battery energy storage system (BESS) is a pre-assembled, all-in-one energy storage solution housed in a standard shipping container. Designed for commercial and industrial (C&I) peak shaving, these systems integrate LiFePO4 batteries, PCS, EMS, thermal management, and fire suppression into a single outdoor-rated enclosure. Our container energy storage systems range from 100kW/215kWh to 1000kW/2000kWh, supporting grid-connected and off-grid applications including solar integration, demand charge reduction, and backup power. Factory pre-commissioned for rapid deployment, each unit is UL9540A and IEC62619 certified for safety and reliability.
Our containerized BESS is factory pre-commissioned. On-site installation typically takes 1-3 days including electrical connection and system commissioning.
