The noise level is kinda load but I don't mind cuz I can know it have turned on while In the house. And it's bare able noise. Best to have it so when bad weather comes your ready to keep your family safe and house well lite. Continue your activities and keeps children from panicking. A very good item to have. Also it u can set a schedule on the mobile app to test run the unit that way it keeps all oils and moving parts lubricated and ready to work when it needs to. Also if there's anything wrong it should send information to your mobile app. Very well thought to protect your investment.

So far so good. It does it's periodic maintenance start up periods, but the peace of mind with the el nino winter we are suppose to have in Virginia was worth the costs. No one I checked with would touch this price plus the switch and 10 year warranty Happy camper so my tail is wagging!

Pattern Name: GeneratorStyle: 18kW + 200-Amp SwitchVerified Purchase

Although we haven’t had much opportunity to try the generator, I believe it will work well for us during power outages.
It took several days to get here, but when completed everything worked just as it was supposed to.

Reviewed in Canada on December 16, 2023

Pattern Name: GeneratorStyle: 10kW + 100-Amp SwitchVerified Purchase

Back up home power, Amazon delivered but Generac customer support did not. Generator has a low oil pressure warning fault and kicks off line. Filed a warranty claim. Local dealer, Whitepine Electric did the service call after a month, didn’t have parts, said they’d be back, that was two months Ago. Generac hasn’t followed up. Purchased in July, It’s now almost Christmas and still doesn’t work. Local dealer aren’t interested in serving if it wasn’t bought by them. Amazon needs to pressure Generac to service their products.

Excellent thing but not easy for installing.

Reviewed in Canada on April 17, 2023

Pattern Name: GeneratorStyle: 10kW + 100-Amp SwitchVerified Purchase

It is my second generator, first was in 2006, but because we are traveling we need to know status of the generator because is important in our situation. This generator has WiFi and I can control status from any place of the world.
Disadvantage - long time for delivery (100 miles take almost a week) and price over twice what I paid for old one and old one had completely set of wireling and materials for completing a job. Right now this materials cost a lot.
I hope that quality will be OK
