Product details

Housed in a standard 20ft or 40ft shipping container, this battery energy storage system brings lithium-ion storage to utility and commercial sites. Offered from 1MWh to 5MWh, it combines liquid cooling, a built-in BMS, and IP67 protection to bank solar and grid power for peak-shaving, backup, and hybrid-grid use across industrial and commercial settings.

Design & Construction

  • Container shell equipped with liftable corner castings for transport handling
  • Vertical racks of stacked lithium modules, fitted with orange high-voltage connectors and organized cable runs
  • Dedicated PCS and control cabinet area with a monitoring and control panel
  • Closed liquid-cooling loop that evens out cell temperature and extends cycle life
  • Weatherproof IP67 build for outdoor installation

Applications

A fit for industrial and commercial storage projects, solar-plus-storage farms, peak-shaving and load-shifting schemes, and hybrid-grid backup at megawatt-hour scale.

Customisation Options

Capacity (1–5MWh), system voltage, container footprint (20ft/40ft), grid setup, and communication interface can be configured per project.

Ordering Information
