About Home Power Calc

Home Power & Project Calculators is a static-first calculator website for home backup power planning. The MVP focuses on generator sizing, battery runtime, solar charging, UPS runtime, CPAP backup estimates, RV camping power, and home outage planning.

The site is built around transparent formulas and user-provided inputs. It does not rank products, recommend brands, publish testimonials, or claim real-world test results.

Every result should be treated as a planning estimate. Device labels, manufacturer manuals, qualified professionals, and local safety guidance should be used for safety-critical decisions.
