### Key Features:


- **Integrated Design**: The PowerStack is a highly integrated energy storage system (ESS) that simplifies transportation and operation and maintenance (O&M). It comes pre-assembled, eliminating the need for on-site battery module handling and enabling installation and commissioning within 8 hours.
- **Advanced Liquid Cooling**: Utilizing intelligent liquid-cooling temperature control, the system ensures balanced heat dissipation with a cell temperature difference of ≤2.5°C. This technology extends the system's lifespan to over 10 years and reduces auxiliary power consumption by 33% through AI-controlled thermal balance.
- **High Efficiency**: The built-in Power Conversion System (PCS) boasts a maximum efficiency of 99%, contributing to an overall system round-trip efficiency (RTE) of 90%. This ensures more efficient power supply and optimized energy usage.
- **Intelligent Energy Management**: Equipped with an intelligent Energy Management System (EMS), the PowerStack supports various functions such as Virtual Power Plant (VPP) integration and off-grid operation. It enables multi-dimensional dispatch across scenarios like photovoltaic (PV) integration, energy storage, charging stations, and diesel power generation control.
- **Enhanced Safety**: The system incorporates comprehensive safety features, including AI monitoring of cell health with early warning capabilities to manage thermal runaway, three-level overcurrent protection (PACK, RACK, PCS), and a three-level fire safety design with accurate early warning mechanisms to prevent fire events.


The Sungrow PowerStack 225kWh Liquid Cooled C&I Energy Storage System is an ideal choice for businesses seeking a reliable, efficient, and intelligent energy storage solution to optimize their energy management strategies.
