A 1044 kWh / 500 kW 10-ft liquid-cooled ESS container built for EPCs, distributors, and C&I energy storage buyers, supporting peak shaving, backup power, solar-plus-storage, and microgrid deployment.
Integrates 20 LFP battery PACKs, 4 PCS modules, grid connection, cooling, and fire protection inside one 10-ft container, delivering 1044 kWh capacity with a smaller site footprint and easier project deployment.
The built-in STS enables on/off-grid transfer within 20 ms, helping maintain stable power for critical loads during grid faults, outages, or weak-grid operation.
Independent battery string monitoring improves fault isolation, operating reliability, and maintenance visibility, making the system easier to manage in large C&I energy storage projects.
Reserved interfaces for PV inverters and diesel generators support solar-plus-storage, PV-BESS-diesel hybrid microgrids, backup power, and multi-source energy management.
Liquid cooling with forced air cooling helps control battery temperature during high-power charge and discharge, supporting long cycle life, stable output, and lower thermal stress.
Pre-integrated container design reduces on-site installation work, commissioning complexity, and project delivery risk, helping buyers shorten lead time and control total ESS system cost.

Everything You Need to Know About CubePal ECO-E10FT1044LP-2
The CubePal ECO-E10FT1044LP-2 is a 1044 kWh 10-ft liquid-cooled ESS container designed for commercial, industrial, and utility-scale energy storage projects. It integrates LFP battery packs, PCS modules, STS, EMS, liquid cooling, and fire protection into one factory-built containerized battery energy storage system.
It is suitable for factories, industrial parks, commercial buildings, solar-plus-storage plants, microgrid projects, renewable energy integration, and industrial backup power systems that require reliable C&I energy storage and flexible power management.
The system stores electricity during low-cost periods or when solar generation is available, then discharges during peak-demand hours. This supports peak shaving, load shifting, demand charge reduction, and better energy cost control for commercial and industrial users.
Liquid cooling provides more stable battery temperature control during frequent charging and discharging. Combined with forced air cooling, it helps reduce thermal stress, improve battery consistency, and support long-term operation in high-cycle energy storage applications.
Yes. The system supports integration with PV inverters and diesel generators, making it suitable for solar PV + energy storage systems, PV-BESS-diesel hybrid microgrids, off-grid backup power, and renewable energy utilization projects.
Yes. With integrated STS functionality and on/off-grid switching within 20 ms, the ECO-E10FT1044LP-2 can help maintain power supply for critical loads during grid interruptions, weak-grid conditions, or emergency backup scenarios.
The system uses LFP battery technology, intelligent BMS monitoring, high-voltage protection, liquid cooling, pack-level and container-level aerosol fire suppression, and a water spray system to improve operational safety throughout the energy storage lifecycle.
