There are a number of advantages in installing an automatic home generator rather than using a portable generator during an outage. These include: Portable generators run the risk of deadly carbon monoxide poisoning when running. Propane is much more cost effective to power your home than gasoline during a power outage. A whole house generator will start within seconds of detecting a power outage. This eliminates the need to haul out your generator and run extension cords throughout your home. Home generators provide 24/7 protection, whether you’re away on vacation, sleeping, etc. There is no need to check if power has returned or monitor your system during an outage.n
