Automatic vs. Portable Generators

What are the differences between an automatic standby (permanent) generator and a portable generator?

During a utility power outage, an automatic standby generator provides numerous advantages over a portable generator:

Automatic standby generators keep your home protected from deadly carbon monoxide poisoning which is a much greater risk with portable generators.
A whole home backup generator runs on your home’s natural gas or propane fuel supply, making it is less expensive to operate than portable generators that are powered by gasoline.
Standby generators eliminate the hassle of hauling a portable generator outside or running extension cords throughout your home.
They provide protection 24/7, whether you’re home or away.
The units turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.
Because an automatic standby generator is hard-wired into the electrical system of your home, appliances like furnaces, well and sump pumps, and lights will operate as well as items you designate.
With their sound-deadening enclosures, automatic standby generators are much quieter than portable generators.
Automatic standby generators do not require refueling. Portable generators require gasoline and need to be refilled. Electrical outages may render gas pumps inoperable, and gas may be unavailable.
The American Red Cross recommends permanently installed standby generators as a safer way to provide backup power to a home than a portable generator, especially if you have family members who require oxygen or have other medical conditions.
