On 1/02/2017 we lost electricity at 8:25 AM just as I began to work on an important project in my home office. In 7 seconds my General 22 kw generator turned on, restored power to all but a/c systems. After an additional 20 seconds the first a/c system came back and 15 seconds later the next one turned on. I was able to work for the 3 hours that it took for service to be restored. The generator is just outside my window and the sound is similar to a riding lawnmower at idle! What great peace of mind.

Received the unit in a timely manner, extremely well packed Was installed by me without drama, not the easiest for a somewhat non-qualified amateur but if you have reasonable electrical skills & a bit of common sense along with the willingness to follow instructions (not my greatest trait,, ) ,,,,,,,,,, it's not bad So far so good the only thing it doesn't like is my air compressor but I knew that going in as it draws ±180amps measured on start so is going to need a soft start modification & hopefully that will make it happy.

Thoroughly pleased with my standby generator. My mind is always at ease knowing that losing power in my house will be prevented by my Generac standby generator. We lost power about a month ago for an hour and within a few seconds my generator started and I had full electrical power throughout my house. What a great feeling!

My wife and I are in our mid seventies, and it's a nice feeling knowing we won't be without what we need when we need it. This is here for us, and we can't ask for anything more than that. One of the best investments we made for ourselves. Thank you Generac.

I have 2 outagedes already and the system work great, when the power went out and come on. This was great the first one was around 4 hours and I am total Electric, TV worked Lights worked, refrig stay on & the heater stay working. Great system. I am proud I bought it and it was a easy installed and delivery. A Big Thank you

I had my generator installed a few months ago. The transaction was top of the line. From the Owner (Russell) to the installer's, completely professional and courteous. Last week the main power went out and within seconds the generator automatically did exactly what it was supposed to do. Now I have the peace of mind knowing that even if I am away from home, my home will be supplied with power!! Great investment!!

I upgraded my Generac Guardian generator from 15KW version to a 22KW version (due to load increases). I have to say I am pleasantly surprised on the quality of power being delivered. The old generator fluctuated several hz (+-2 Hz) and had a hard time holding a steady voltage. We are using this generator to power a small data center, power quality is important as UPS don't like dirty power. This new generator holds voltage steady, the frequency is within +-0.1 Hz. Even when the large roof top air conditioning unit kicked in, the generator powered up and recovered the correct voltage and frequency within a second. The power monitoring is also a nice touch. Now I know when we loose power and if the generator kicked in or not. Although the old unit mechanically was working fine, visually the case was metal and rusted heavily. This new case is aluminum so we are expecting no rust.

Good product. Very good documentation. Installing a generator and transfer switch was a lot of fun for me. There is plenty of reference material on the web to help size gas pipe and wire and conduit. I used all 600 volt rated wire in pvc conduit. I was not impressed by the multi conductor cable that dealers were quoting. I'll be able to do all maintenance on the unit. Hopefully I won't need any warranty work.

We're about 6 months into ownership now, and have experienced 1 power outage. The machine performed flawlessly. We live in a rural area area where power is lost quite often due to storms and it's really comforting to know life is not interrupted because of that. That said, I wish to add the home surge protector was also a worthy investment. Thank you Generac.

This generator installed in September 2016 by and authorized dealer. Since then, we've had two power outages and the unit functioned perfectly both times. It's not too noisy (something we appreciate during the weekly self-test) and seems to be very fuel efficient. We have a 22 Kw system, and have been able to run pretty much everything we wanted when it was in operation. Overall, we're very pleased and wish we had gotten a Generac sooner.
