I have been wanting to purchase a whole home generator for some time. Finally bit the bullet an got a 26KW with transfer switch about a month ago. 2 days ago, 08/13/26, the power died for about 4hours. Unit kicked in flawlessly and handled central AC, stove and package AC unit with ease. I like the fact that natural gas is always ready to go when problems arise. Install was truly professional and exactly as promised. I'm a satisfied customer!
Yes, I recommend this product.

The app is very good and verifies its working
3 days ago
Had this 6 weeks now, just before storm season. Good quality product but difference is the installation by a company that only does generators, not some diversified franchise or one-at-at-a-time electrician. Family run business that concentrates on Generac and installs 5- 7 per week. The price was $2800 less than other vendors and they gave me the confidence of a quality installation and maintenance program.
Yes, I recommend this product.
