- Generac generators and engines are engineered and assembled in the USA*.
- Generac's G-Force Engine is a purpose-built, pressure-lubricated engine capable of handling the rigors of generator use, resulting in power that’s more reliable and requires less routine maintenance than any competitive engine.
- Quiet-Test™ Self-Test Mode runs at a lower RPM for a five or twelve minute test, making generators significantly quieter than other brands while consuming less fuel.
- 24/7/365 Customer Support Team standing by all day, every day from our headquarters in Wisconsin to answer any questions you might have.

Generac 6551 Guardian 22kW Standby Generator New w/ 200 Amp Automatic Transfer Switch New
I ordered a 22kw generator and ATS for my house. Ordered on August 10, delivered on August 17. Wish it would have come with a battery, even if added as an accessory. Just a suggestion.
best place to purchase Generator good customer services
I received the generator early. I still don’t have it in service but plan on starting the installation next week.
My friend has one and he loves his.
