About five years ago I was trapped for a week at a customer's island vacation home where I was staying while doing some remodeling. We had a bad storm that produced a micro-burst with straight line winds estimated at 80 mph. Downed trees and power poles blocked the only road in.
The year before the owner had installed a Generac whole-house generator. It ran everything for the entire week I was trapped there. It was like I never lost power. the only concern was running out of propane in his 500 gallon tank.

We have been experiencing power outages on a regular basis here in southeast PA for the last several years now. First Energy, our power company, does do not the maintenance or keep qualified personnel on the payroll, we customers pay the price. Outages are nearly monthly and last a minimum of twelve hours and are often days-long.

My Generac 5500 does a good job of providing us with the essentials during outages but it's a pain to drag out of the shop and hook up then put away again.

I'm seriously considering a whole-house set-up. If I go that route it will be a Generac. I've had good experience with their products and that's what all the folks around the lake where I was stuck on the island use.
