Fast Power Transfer

I finished installing generator a mouth ago. Pretty straightforward installation. I had my first outage during a storm last week. Generator started and transferred power within seconds. Very happy with quality and performance of my new generator system.

You won't be disappointed!

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!

Peace of Mind

I purchased this one year ago. It is whole-home capable, completely automatic and easy to monitor with the phone app and the Ecobee thermostat. The generator responds to power loss in seconds. It is very reassuring to know that if our home loses grid power while we are away the app will notify us.

The app is very good and verifies its working

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.

Best Buy Ever!

Best buy we have ever made. A month and a half after it was installed, we had a big windstorm in Montana (in December). Power was out for 3 days, but our Generac generator started right up and kept running for 3 days, with NO problems at all. Kept us warm, kept the lights on, kept the hot tub hot. We could cook and go on with our daily lives with no hitch. It's a Godsend!

Reliable Protection

Purchasing this generator was similar to putting up a magical ward against power failures. Where the original motivation was a frequent number of outages, we've not had any single outage since installation. In it's standby configuration it's met our expectations.

Beware of additional annual costs

Be careful about the add on costs for maintenance and other cost items not disclosed at purchase time. Could be over $600 annually .

Don't buy this unreliable generator

I bought this NextGen 28kW to replace a rusty but reliable 20 year old 35 kW Generac. Our NextGen failed immediately at our first power outage 3 weeks after installation and is still nonfunctional after 3 service trips and more than 4 hours labor over the last week.

Junk wish I would've went with a different company

L I bought this generator less than a month ago and it broke down within the first month installer keeps canceling my appointments to figure out what's wrong.
