Energy and power calculator
Home-battery backup selector
Households choosing a battery-backup class. The decision this page isolates is narrow on purpose: translate essential kwh into a home-battery class. Load and runtime are separate constraints. A watt number alone is not a complete answer.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank EcoFlow, Jackery, and Anker. It produces an explainable class so EcoFlow DELTA Pro, Jackery Explorer 2000, and Anker SOLIX F3800 can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in Generac. This page does not quote a price or rank a brand.
How to use this calculator
