ECO 125 kW / 261 kWh Commercial and Industrial Energy Storage Integrated Unit

The ECO125kW/261kWh is the flagship outdoor integrated cabinet product in Changhong’s commercial and industrial energy storage series. It has a rated output power of 125kW, a DC-side battery capacity of 261.2kWh, and adopts a 1P260S battery configuration with a voltage range of 650–949V. Featuring an outdoor integrated cabinet design, it is plug-and-play and boasts an IP55 protection rating and a corrosion resistance rating of C3/C5. Its liquid-cooling thermal management system ensures efficient and stable operation, while a combination of perfluorohexanone and cell-level targeted fire suppression provides multi-layered safety protection. The system supports 100% three-phase unbalance compensation and is compatible with grid-connected energy storage and voltage regulation for both urban and rural distribution networks. It complies with the national standards GB/T36276-2023, GB44240-2024, and GB/T44026-2024.
