How It Sizes
Recommendations are based on average load, runtime target, reserve, AC efficiency, running watts, and startup surge.
Capacity first
The tool converts the selected load profile into Wh needed, then adds reserve and a sizing buffer.
Output second
Candidate models must clear running watts and source-backed surge checks before they appear.
Trust before ranking
Model suggestions are source-backed starting points, not paid placement or affiliate ranking.
