How Inverter Sizing Works In GridGap

The Inverter tab is trying to answer two different questions at once: what the inverter must handle continuously, and what it must survive during surge-heavy moments.

Continuous power

Minimum continuous inverter is the lower bound based on the modeled running demand. Recommended inverter is the more practical planning recommendation after headroom and conservatism are applied.

System Voltage reminds you of the DC system context, which matters for the wider battery and charging design.

Surge interpretation

Minimum surge, recommended surge, and worst-case surge show the app's attempt to surface the startup stress caused by motors, compressors, pumps, and similar loads.

Surge assumptions is there to remind you that the surge side of inverter planning is only as good as the appliance surge data you entered.

Load percent

Inverter load percent helps you see how hard the chosen or implied inverter size is being pushed under the scenario assumptions. A high value is not automatically wrong, but it usually deserves closer review.
