Product Description
The UEI-BESS-2.5MW / 5MWh is a turnkey containerized energy storage solution engineered for grid-scale and commercial energy management. Housed in a prefabricated 40ft container, the system integrates 2.5MW power conversion, 5MWh of high-voltage LFP batteries, a step-up MV transformer, and full monitoring and safety infrastructure.
It contains 14 battery clusters of 358.4kWh each (1280V @ 280Ah), two 1.25MW energy storage inverters (PCS), and all necessary components including DC combiner cabinets, MV switchgear, local communication and EMS cabinet, fire suppression, HVAC, lighting, and power systems.
The entire system is fully factory-tested and designed for plug-and-play installation with minimal on-site wiring. It supports black-start operation, peak shaving, load shifting, and microgrid integration, making it ideal for large factories, data centers, renewable integration, and backup applications.
