How Battery Sizing Works In GridGap

The Battery tab shows both the theoretical requirement and the practical bank that would be needed to meet that requirement under the current assumptions.

Top battery metrics

Battery output required is the energy demand the battery must actually supply. Nominal capacity required, temperature adjusted capacity, Peukert factor, and final required battery capacity show how the requirement grows as the app applies more realistic constraints.

Required system Ah converts the requirement into system-level amp-hours at the chosen voltage.

Bank configuration

Series count, parallel strings, and total batteries describe the resulting bank layout. The aim is to show not just the energy target, but the practical number of units implied by the selected battery voltage and the chosen system voltage.

Battery Unit kWh / Ah, Battery Entry, and Battery Voltage help remind you what one battery unit represents and how the app interpreted the input.

Reserve and depletion

Actual installed capacity and actual usable capacity show the real bank totals based on the final battery count. Depletion percent and reserve Wh and percent indicate how hard the scenario pushes that bank under the current assumptions.
