Verified Purchase

has weekly self test

Having the generator give peace of mind. I am disabled from a medical condition; do not have to worry about going outside awry about starting and fueling a standby unit.

Bought this a month ago and so far I'm fairly satisfied. Have had a couple of problems with it and still haven't received in paper my paperwork for my 10 year warranty

Peace of Mind and Reliable

Having experienced "Snowmageddon" in North Dallas a few years ago and without power backup, this new Generac whole home generator brings incredible peace of mind. It's good to know it is always there ready to take over should the power grid go down. The only reason I gave it a 4-rating is because of the delay between power failure and the generator starting. I wanted Tesla's system mainly because of its ability to take over within milliseconds of losing power unlike Generac. If power is out for more than a second, then there are several clocks that have to be reset. I've had days when the power blinked multiple times thereby requiring clock resetting each time. Very annoying. If Generac would develop a battery unit to incorporate with the generator that would bridge the gap between the grid failing and the generator taking over, then I would definitely give it a 5-star rating. That's my only complaint, and it really isn't a Generac fault since it operates as designed. I just wish the design would change a tad to eliminate the time gap.

Generac Generator

In my previous residence, I installed a Generac generator, and its reliability has consistently been exceptional. Furthermore, the maintenance process is straightforward and hassle-free. I have encountered no issues whatsoever with the Generac generator, making it a highly recommended investment.

We love our Generac!

We had our Generac installed during the winter. The process was handled with care and patience. We have family and friends with Generac home generators and we heard nothing but good things about them. The generator is turned on remotely once a week to make sure everything works properly. It's so good to hear it running and to know it's ready at a moments notice.

Fantastic insurance for inconvenience

At my age of 67, I am glad to finally get an install a Generac standby generator. Even if the power just goes out for a few hours, it will be much easier to put up with the inconvenience. Basically there won't be an inconvenience. I believe standby generators are worth every penny.

Works great when not triggering error messages

This is my second home with a generac and I am very disappointed in the new unit on my current home. It keeps encountering errors after it starts running which defeats the purpose of having a generator. It's terribly disappointing to spend so much money to prevent energy outage at our home/business, but with no better outcome than others that have not installed a generac. I truly hope that this software issue with our new generator will be resolved soon by generac.

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.

Never be with out

We have 2 homes. One is a small ranch in the country that has 10 other people on the power leg. It is not uncommon to have power outages frequently. During an ice storm power was out for 2 weeks. Not mine! The other home is a lake home which also takes a long time for power to return to normal. Bottom line is we will not have home with out a generator. We use the 22K on propane. The ranch has 2 large a/c units, 2 upright freezers and 2 refrigerators. The generator runs the whole house just fine.

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.
