The LiPal ESS-E261LP is engineered as a compact 261 kWh liquid-cooled ESS cabinet for commercial and industrial energy storage projects. With integrated PCS, BMS, EMS, liquid cooling and multi-level safety protection, it helps EPCs, project developers and facility owners simplify deployment, improve thermal stability and reduce long-term operating risk.
The space-saving cabinet design reduces installation area and simplifies project layout, making it suitable for factories, commercial buildings, industrial parks and retrofit C&I energy storage sites.
Battery packs, 125 kW PCS, BMS, EMS, liquid cooling and fire protection are integrated into one factory-built cabinet, helping reduce field wiring, commissioning time and system integration complexity.
The in-pack liquid cooling design helps maintain consistent battery temperature, reduce thermal stress and support stable charge-discharge performance in high-cycle C&I energy storage applications.
High-performance LiFePO4 battery cells deliver long cycle life, strong thermal stability and reliable energy output for peak shaving, PV self-consumption, backup power and demand charge management.
The modular architecture supports parallel expansion, allowing EPCs and energy storage system buyers to scale capacity based on load profile, site conditions and future power demand.
Real-time BMS monitoring, smoke and temperature detection, aerosol fire suppression, high-voltage protection and thermal event mitigation work together to enhance cabinet-level operating safety.
