Whole Home Generators 101
1. Automatic Backup Power
A whole home generator turns on automatically when utility power is lost, keeping your home running without any manual setup.
2. Professional Installation
These systems are professionally installed outside your home and connected directly to your electrical panel for safe, reliable operation.
3. Essential or Whole Home Power
Depending on the system, a generator can power essential circuits — or your entire home — during an outage.
4. No Refueling Required
Whole home generators use a steady, reliable fuel source, so there’s no refueling or fuel storage to worry about.
5. Built for Extended Outages
Unlike portable generators, whole home systems are built to run for extended periods during severe weather or widespread outages.
