The 1.2MWh system integrates multiple battery racks composed of 314Ah LFP cells in series-parallel configurations, typically housed in an outdoor cabinet or container. It includes air-cooling fans, an integrated BMS, fire protection, and EMS communication interfaces.

Air cooling reduces system complexity and cost, making it ideal for moderate climates and applications with lower C-rate requirements. For 1.2MWh systems, enhanced airflow design and redundant fan architecture ensure safe and stable thermal management under continuous cycling.

This configuration is well-suited for commercial and industrial energy peak shaving, PV self-consumption optimization, microgrid support, backup power for data centers, or EV charging station load balancing in environments with mild-to-moderate temperature ranges.

The system includes intelligent BMS monitoring, over-temperature alarms, airflow detection, smoke/fire sensors, and automatic fire suppression (e.g., aerosol or gas type). Fan redundancy and thermal runaway isolation design further enhance operational safety.

Air-cooled BESS systems are easier to install and maintain compared to liquid-cooled units. Routine maintenance involves fan inspection, dust filter replacement, thermal sensor calibration, and remote diagnostics via EMS. The modular design allows rapid deployment and flexible site layout.
