The Generac Protector 27 kW generator includes all of the same great features in the smaller 22 kilowatt version.

Plus, it features a more powerful Generac engine capable of producing an extra 5 kilowatts of electricity.

I have worked on this property for the previous owner since 1995 and had installed a manual generator system. The new home owner was not comfortable with having to go out in a storm and "Hook Up" the portable generator and also having such limited power available.

The house has 400 Amp service thru 2 - 200 Amp panels. We installed 1 - 27 KW Generac unit with 2 Auto Switches and load shed for 2 - 7 ton AC and 1- 5 ton AC. Transfer is in 20 seconds and the customer is bragging to... more

Very sorry to hear about the problems you've been having with your generators. Having two different failures on two different types of generators is almost unheard of if you're using these generators for what they're designed for, backing up a reliable utility source of electricity.

Please keep in mind that as an online retailer for Generac, all warranty work has to be performed by a Generac servicing dealer. If you're having issues locating a servicing dealer in your area, I would suggest contacting Generac directly @ 888-436-3722.
