About us

Home Backup Power Guide answers the practical questions US homeowners ask about backup power before the next outage.

Home Backup Power Guide is written and maintained by the Home Backup Power Guide editorial team. We cover how to size a portable power station or home battery, how generators compare, what a transfer switch or interlock does, and how to run backup power safely.

What we are, and what we aren't

We are not electricians, engineers or tax advisers. We research each topic from primary sources (government agencies, safety regulators, codes and manufacturer documentation), show our math, link every source, and tell you when to hire a licensed electrician.
