Seplos UltraPower 261 Liquid Cooling Microgrids BESS
The Seplos Ultra Power 261 is an all-in-one liquid-cooled ESS designed for commercial and industrial energy storage as well as utility-scale battery storage projects. It integrates 261kWh high voltage battery packs, PCS, BMS, EMS, and an advanced liquid cooling and fire protection system, delivering reliable and efficient energy management.
As a next-generation high voltage power supply solution, the system addresses key market challenges with precise thermal control (cell temperature difference ≤2.5°C) for extended battery life, as well as early thermal runaway warnings, gas detection, and automatic fire suppression for enhanced safety.
The system functions as a robust high voltage DC power supply for grid-tied, off-grid, and microgrid applications, including participation in virtual power plants and renewable energy integration. Its factory-prefabricated modular design minimizes installation and commissioning costs, while cloud-based monitoring and AI-driven predictive maintenance reduce O&M complexity and maximize ROI.
