Product Group Information

The ESAI containerized series delivers turnkey, commercial and utility-grade battery energy storage by integrating batteries, power conversion systems (PCS), thermal management, fire protection, and supervisory controls into a single, factory-assembled container platform. Designed for MW/MWh-scale deployments, ESAI series reduces on-site complexity, accelerates project timelines, and minimizes integration risk. Built for grid services, renewable smoothing, microgrid applications, and large commercial energy optimization, ESAI provides high-efficiency power conversion, intelligent system monitoring, and modular scalability to match evolving capacity requirements. Factory integration and pre-validation streamline engineering, procurement, and commissioning, reducing field labor and improving schedule certainty.

Operating Temperature Range:

-4°F (-20°C) to 104°F (40°C)

Group Information:

Containerized, all-in-one battery energy storage systems integrating batteries, PCS, thermal management, and controls for utility-scale and MW/MWh commercial projects.

Product Description:

All-in-one energy storage built for performance, control, and long-term value. The ESAI-840/2064 (NA) delivers 840 kW of power and 2064 kWh of capacity in a fully integrated, high-capacity containerized energy storage system, designed for large-scale commercial, industrial, and grid applications. By combining batteries, PCS, and control systems into a single containerized platform, the all-in-one BESS enables streamlined deployment while supporting centralized energy strategies across complex sites and high-demand operations. Engineered for demanding applications, the system supports advanced operating modes, including grid-connected, off-grid, and hybrid, allowing operators to optimize energy flow, manage peak demand, and maintain resilience under varying load conditions. With scalable, parallel architecture and independently managed battery strings, the ESAI-CON Series enables efficient capacity expansion, simplified maintenance, and improved system performance over time. Advanced battery management, multi-layer safety systems, and compliance with global standards ensure safe, reliable operation while meeting regulatory and insurance requirements. Designed for long-term performance, the ESAI-840/2064 (NA) integrates advanced thermal management and intelligent controls to maximize efficiency, extend battery life, and deliver consistent, high-output energy at scale.
