The CubePal ECO-E20FT2170LP-2 is a 2170.3 kWh / 1125 kW 20ft liquid-cooled ESS container designed for utility-scale storage and large C&I energy projects. With factory-integrated PCS cabinets, 45 LFP battery PACKs, string-level management, hybrid cooling, and multi-level fire protection, it helps EPCs, distributors, and project owners build scalable solutions for solar-plus-storage, peak shaving, microgrid, and backup power applications.
The 20ft container delivers 2170.3 kWh battery capacity and 1125 kW rated output, supporting high-power utility-scale and industrial energy storage projects while reducing system integration complexity.
Liquid-cooled battery packs work with forced-air cooling for PCS and auxiliary equipment, helping maintain stable thermal performance, lower battery stress, and reliable operation in demanding outdoor environments.
Independent battery cluster monitoring improves fault isolation, energy consistency, and maintenance visibility across 45 LFP battery PACKs, making the system easier to manage for large BESS projects.
The pre-installed container integrates PCS, EMS, battery system, cooling, and fire protection before delivery, helping EPCs shorten commissioning time, reduce site work, and better control total project cost.
Pack-level and container-level aerosol fire suppression, water spray support, thermal monitoring, and high-voltage protection work together to improve safety across the full ESS lifecycle.
Built for solar-plus-storage, peak shaving, load shifting, microgrid, and backup power, the system supports flexible deployment for energy developers, distributors, and large commercial power users.
