Basic Quick win

BackupFit

A brand-agnostic web calculator where homeowners enter their critical circuits and get a recommended battery/inverter capacity in kWh.

01

What to build

  • MVP

    A form-based calculator that takes appliance wattage and outage duration inputs and outputs a generic kWh sizing recommendation, similar to existing solar sizing tools.

  • Why it can be better

    Faster and cleaner than scattered GitHub scripts, but still just outputs a generic capacity number like Unbound Solar or WattMath without checking it against any real product's specs.

  • Revenue model

    Affiliate links to battery/generator retailers on the results page.

  • Target user

    Homeowners researching backup power after a search for 'how much battery do I need'.

02

Context

The opportunity this answers

Build a brand-agnostic backup-sizing and load-matching advisor that recommends the exact battery, inverter, and panel setup for a specific home.

Why now

Backup brands have just pivoted from single-purpose portable power stations to whole-home marketing, splitting the market into incompatible tiers right as low-upfront-cost entrants like Base Power change the economics of adoption, so buyers face more confusing choices exactly when volatile, storm-driven search spikes push them to decide fast without any neutral way to compare branded tiers against their actual home loads.
