241kWh Commercial Energy Storage System (BESS) — 125kW All-in-One LiFePO₄ Battery Cabinet


Product Overview

The 241kWh BESS Cabinet is a turnkey commercial energy storage solution engineered for medium-to-large industrial and commercial applications. Integrating high-quality LiFePO₄ battery modules, a multi-level BMS, DC/AC distribution, and an enclosed air-conditioning cooling system within a single IP54-rated enclosure, it delivers safe, silent, and maintenance-friendly operation.

With a 125kW rated power output and support for parallel expansion up to 12 units (≈2.9MWh / 1.5MW), this system is ideally suited for:

  • Electricity cost reduction through peak shaving & valley filling


  • Demand charge management (reducing maximum demand penalties)


  • Critical load backup during grid outages


  • Buffering renewable energy in hybrid microgrids (when paired with external PCS)
