InverterReviewed Sep 2026

The short version

Works with your grid day to day, then takes over by itself when the power goes out.

Who it's for

Great for
  • Grid-tied homes that want backup
Not for
  • Fully off-grid homes (use the XP line)
The catch

Connecting it to your home's breaker panel needs a licensed electrician and usually a permit.
