The Automatic Alternative
If you have access to reliable natural gas or propane, sometimes a large emergency portable generator isn't the best option.
With a portable generator, you must manually set it up and refuel it with gasoline every time the power goes out. In addition, you'll need a 10-circuit manual transfer switch installed by an electrician.
As a better alternative, consider the new Generac CorePower automatic standby generator system.
It's installed outside your home like an air conditioner and automatically starts when power goes out. Since it produces the same wattage of a large portable generator, it can automatically energize 8 mission-critical circuits - minus a central air conditioner.
Best of all, the Generac CorePower costs about the same as a large portable generator and power transfer system combined. Both require electrical installation.
The CorePower will require a plumber to connect the fuel supply. However, the one-time plumbing cost is a better alternative to multiple trips to the gas station during a blackout.
