What is a BESS?
A Battery Energy Storage System (BESS) is an industrial-scale battery solution used for grid stabilization, peak load shaving, renewable energy integration, and backup power (UPS). These systems range from small-car-sized units to full shipping container installations, and include battery modules, power conversion systems (PCS), battery/energy management systems (BMS/EMS), thermal management, and protective enclosures.
