Part of our Backup Power & Generators Hub.

Home generators provide emergency electricity during power outages. Severe weather events, grid failures, and infrastructure disruptions can leave homes without power for hours or even days.

Backup generators allow homeowners to maintain electricity for essential appliances such as refrigerators, heating systems, internet routers, and medical equipment.

What Can a Home Generator Power?

The number of appliances a generator can power depends on its wattage capacity. Smaller portable generators typically power essential appliances, while standby generators can support entire homes.

  • Refrigerators and freezers
  • Lighting circuits
  • Internet routers and modems
  • Heating systems
  • Sump pumps
  • Medical equipment

Portable vs Standby Generators

Portable generators are more affordable and can be used during temporary outages. They require manual setup and fueling.

Standby generators are permanently installed and automatically start when the power grid fails. These systems are ideal for homes in regions with frequent outages.


Backup Power Alternatives

In addition to traditional generators, many homeowners are installing battery storage systems connected to solar panels. These systems provide quiet, renewable backup power without fuel.
