Description Key Features Fully Integrated All-in-One Design: Eliminates installation headaches by integrating the LiFePO4 battery pack, Power Conversion System (PCS), and Energy Management System (EMS) into one compact, ready-to-deploy cabinet. Precision Liquid Cooling System: Advanced thermal management maintains cell temperature differences within a tight 3–5°C margin. This ensures stable high-power performance, maximizes energy efficiency, and guarantees a 10-year calendar life. High-Capacity Powerhouse: Utilizing high-density 280Ah and 314Ah LiFePO4 cells, a single cabinet provides up to 261kWh of energy and 125kW of output power, perfect for heavy industrial and commercial loads. Massive 2.4MWh Scalability: Start with a single cabinet and scale your energy storage effortlessly. The modular architecture supports parallel expansion up to a massive 2.4 MWh to meet growing commercial energy needs. Hybrid On/Off-Grid Operation: Delivers seamless transitions (≤20ms) between grid-tied and off-grid modes for uninterrupted power. It can also be equipped with an optional MPPT controller for smooth and direct solar integration. Industrial-Grade Safety: Housed in an IP54 fire and explosion-proof enclosure, the system features a built-in Aerosol Safety System and an intelligent BMS for precise monitoring, ensuring ultimate protection against thermal events. Applications Commercial Peak Shaving: Perfect for factories, shopping malls, and large facilities to avoid crippling peak-demand utility charges and lower overall energy bills. Hybrid Microgrids: Integrates seamlessly with solar arrays and diesel generators to power remote industrial operations, campuses, or mining sites. EV Charging Hubs: Provides the massive energy buffer needed for multi-bay DC fast-charging stations without overloading the local grid infrastructure.
