Applications & selection

Size the energy-storage system around the load, not nameplate kWh alone

Typical fit

  • Scalable commercial and industrial storage
  • Indoor modular backup
  • Projects expected to expand in phases

Confirm before quotation

  • Load profile, peak kW and required usable kWh
  • Autonomy, C-rate, efficiency and temperature range
  • Site location, grid interface and control requirements

Engineering guides

Commercial BESS sizing checks Turn load data, usable energy, C-rate and site constraints into a defensible specification. Battery runtime calculation See which efficiency, temperature and aging losses reduce usable AC energy. Battery storage RFQ checklist Use the same technical inputs our engineers need to price and configure a system.
