Application requirements
Specify the service first: load shifting, renewable integration, backup or grid support. Power in kW and energy in kWh describe different system characteristics.
Establish the battery, PCS, BMS/EMS, protection, thermal and installation boundaries. Nominal capacity alone cannot determine usable energy, savings or long-term performance.
Selection checklist
- Power and usable-energy boundary
- Battery, PCS and control interfaces
- Protection, environment and lifecycle service
