Container-Scale Centralized System

5MWh Centralized Energy Storage System

Positioned for grid-side centralized energy applications, this system is presented for new-energy storage, thermal-power storage, grid-side standalone storage and transformer-area storage scenarios.

Use cases stated by the source include peak shaving, green-power consumption, reduced wind and solar curtailment, and station-revenue support.
The source also identifies grid stability, auxiliary power services, frequency regulation, voltage stabilization and black start.
Three-level fire protection, three-level pressure relief and a flexible modular expansion design.

Capacity: 5MWh
Cell capacity: 314Ah
Protection level: IP55
Nominal energy: 5015.96kWh
Nominal voltage: 1331.2Vdc
Operating voltage: 1040–1497.6Vdc
Charge / discharge rate: ≤0.5P
Operating environment: -30°C to 55°C; altitude below 3000m; humidity 0–95%

Source parameter-group values are shown with their original product scope; this configuration remains distinct from the string system.

Configuration-specific review

Review Safety and Lifecycle Requirements by Configuration

Safety descriptions on this page are product-specific: the eBox 261 source states seven-level safety emergency response and multi-layered protection; the 2.5MW/5MWh string and 5MWh centralized sources state three-level fire protection and three-level pressure relief; and the 6.25MWh source provides product-specific enclosure protection and standards information.

Lifecycle, warranty, cycle-count, retention and efficiency figures are not established by the evidence used for this page. Include the intended operating profile, environmental conditions and project schedule in the inquiry so those requirements can be addressed during configuration review.
