The 261 kWh / 125 kW liquid-cooled string Battery Energy Storage System (BESS) is a compact and modular energy storage solution designed for commercial and industrial applications requiring high efficiency, fast dynamic response, and long operational life. The system uses high-performance LFP battery cells with a 314 Ah capacity, ensuring excellent thermal stability, high safety margins, and long cycle life.
Each unit integrates a bidirectional string PCS, enabling precise charge and discharge control along with seamless grid interaction. Liquid-cooling technology is applied to both battery modules and power electronics to maintain uniform operating temperatures, improve system efficiency, and minimize cell ageing.
A hierarchical BMS architecture combined with an intelligent EMS provides real-time monitoring, protection, fault diagnostics, and optimized energy management. The system supports modular parallel operation and can be scaled up to 8 identical units, allowing flexible expansion to meet higher power and energy demands for peak shaving, load shifting, renewable energy integration, and backup power applications.
