The 215kWh system typically consists of multiple battery modules built with 3.2V 280Ah LiFePO₄ cells arranged in high-voltage series (e.g., 51.2V or 102.4V per module), stacked into racks within an IP54-rated cabinet. Integrated BMS, air cooling units, fire protection, and EMS interface ensure safety and real-time control.
Air cooling offers a cost-effective and low-maintenance thermal management solution for mid-scale systems. It ensures consistent airflow across battery modules through built-in fans and ducts, keeping operating temperatures within 15–35°C for extended cycle life without the complexity of liquid cooling.
This system is ideal for C&I solar storage integration, demand charge reduction, emergency backup, microgrid stabilization, and EV charging stations. It can be deployed as a stand-alone unit or combined into larger systems (e.g., 430kWh, 860kWh) based on user demand.
The system complies with IEC 62619, UN38.3, CE, and optional UL9540A standards. It features multi-level protections: BMS (overvoltage, overcurrent, overtemperature), thermal sensors, airflow monitoring, smoke detection, and optional aerosol fire suppression.
The system supports remote and local monitoring through EMS and SCADA platforms. Real-time data includes voltage, current, SoC, temperature, and alarm logs. Maintenance includes routine fan filter cleaning and system firmware updates. Modular design simplifies servicing and expansion.
Smart Cities and Green Buildings: Ideal for urban developments and eco-friendly buildings, providing intelligent energy storage solutions that stabilize the grid and reduce energy costs in densely populated areas.
Distributed Energy Systems: Suitable for microgrid applications, helping companies in remote or off-grid locations achieve energy independence and reduce reliance on centralized power sources.
