3 out of 5 stars review

The WiFi doesn't work. It never did. I did everything I could on the home end of things but no dice. This also happened on the second unit as well (I purchased two). So I'm sure it's a good unit but it does me little good if I can't “see it” without actually going to where it's located and popping the hood. Maine winters make that an issue.

Runs quieter and has great App features.

We bought this 24KW four months ago and was only able to get it installed a month ago. So far we're very pleased with it. We bought a 22KW Generac 20 years ago and got a lot of usage out of it in south Louisiana. Back then it was referred to as a "whole house generator" but we soon learned that didn't mean you could run "everything" in the house on it. It running under a load because of a power outage and my wife was running the clothes washer, dryer, microwave, the electric oven and all the lights at the same time and it handling the load just fine until our 3.5 ton AC kicked on and it started to bog down badly. Lesson learned!! We have only used this one in the exercise schedule and not under a load yet. It is quieter than our old one though. Be sure to get the App for it if you want a more detailed status of it and setup an exercise schedule.

Seamless operation during power outage

Weekly test runs are going fine: starts on time and idles low after a short run at full speed (so it is much quieter). First power outage and the transfer switch, generator and power supply started, ran and shut off seamlessly. Impressive. The only improvement would be if it were not that loud: can be heard clearly in the house and even might affect level of speaking or certainly could affect getting to sleep.

No more power worries

I just had this whole house generator installed to my delight. It works seamlessly with household with low noise level. I can run everything in my household without interruption. The only difficulty was using their APP since we are not very Teck savvy.

Love our Generac❤️

We have been thinking about buying a Generac for years. So glad we finally did! Our neighbors had their installation done in 2018. Every time a storm caused an outage, they were completely comfortable, up and running! It has made us feel much more secure with the hurricane season coming.

If you have the extra money, put it to GOOD use!

We have had the unit for about 10 months. It now tests twice a month for 10 minutes self checking and keeping the oil moving around. We had an outage the week after it was installed while we were away. I received a notice of it working, via the app, as it was supposed to do. We have had two other outages last year. The unit performed perfectly. So far so good! I had a year of complimentary wireless coverage. I just signed up for the next year. While not really a cheap benefit, it is nice to have. I may change to testing once a month later. We used to have outages every other month around my neighborhood due to weather, trees and old lines. Consumers has done a good job of cleaning up the lines and overhanging trees. The outages are fewer now, but as an older person, I now join the group of people that are more susceptible to cold, heat and less flexibility in dealing with the inconveniences of power outages. Our Generac should make things easier!

Beware

Died 30 minutes into TS Helene 9/24. Even with all the $$ and "certified" service, a wrong oil filter was used causing an oil blowout through air cleaner. 24 hour support a joke, kept referring to companies inside the storm zone (they were wiped out). Took six month to repair after reaching out to a very large generator company 2 hours away. Oh and mobile kept reporting everything was ok (generator was off) for those 6 months.

Seamlessly continues power supply.

I bought this unit for a rental tiny home on my property. I had already installed a 17kv Generac which services the main house. We have electrical outages several times per year in our rural location and our Generacs work flawlessly to seamlessly continue to provide power when this occurs.

Now we have peace of mind in a storm

We bought our Stand by Generator recently and we are delighted with our purchase. I don't have to dread dragging my walker over the extension cords in the floor when the power is off. Now we simply go on as usual after a few seconds. Thank you Generac and Mr. Allen of Allen Residential Electrical for giving us peace of mind in stormy weather.

Power in mind

Our Generac was installed new, at the end of February and we are really excited to have it. Although the power has not failed as of yet we feel more secure having the backup/emergency power. I have been disabled for 10 years now and having to lug around a portable generator only to run a fridge and furnace fan was getting very hard to manage for me. Now I can sleep a lot better knowing all that and more will be working as it should when commercial power is not available.
