It comes on when power goes out.

Had 15 different power outages in the last 12 months and some outages lasted days. We have had no power outages yet sense we bought and installed the Generac generator. Now when storms come I'm not worried about power loss but I am scared of tornadoes.

Well engineered and assembled!

Although I have just had this unit installed a month or so ago, my wife and I are so happy of knowing that we will have power when there is an outage. The cool thing is that it is scheduled to run every 2 weeks for a few minutes. We have experienced this ‘run’ and it is very comforting to know we have a great solution in case of an outage. In addition, the noise level was outstanding!

warenty useless

after my original warranty ran out I purchased the next warranty and I have spent about $6,000 on repairs because it seems nothing is covered. Had to replace my mother board twice within about 18 months and neither one was covered under warranty along with other problems. It is strange Generac sells a warranty and I have not found one item that is actually covered

New and improved version

Just installed and completed and we have no issues. Had to leave our first Generac at the old house and now have the new and improved version. The simplicity of managing is great, have recommended to our neighbors and they are being installed and ordered as I type.

Generac's fine. Stay away from ACS Home Svcs Tampa

I am very satisfied with the unit itself, however I would never recommend the company used for the installation. They were the worst, most disreputable company ever (ACS Home Services of Tampa Florida) It took us 7 months to get it installed after signing the contract, and they demanded payment in full before they would even deliver the unit to our house after a $1,500.00 deposit at signing.

Nice, dependable system

We replaced an older “essential” circuits Generac generator with a 24kW whole house system. Very happy with both the installer and the new generator. If I would change anything on it, it would be the lid (very flimsy) and it would be much nicer if it were quieter. Other than those two items we’re very happy with everything.

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.

So far, so good!

I have had my generator for about six weeks so far. The installation was quickly and efficiently accomplished. The installation team answered all my questions and explained the operation of the unit. So far, the only experience I have with the unit is when it tests itself every week. I have yet to experience an actual power outage and run on my home on generator power alone.

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.

Portables are nice but whole house clearly better

We purchased a portable generator back in 1999 and used it several times throughout the years. But we are older now and the effort to maintain it and get it operational has become more challenging and so a whole-house "automatic" start generator made more sense.
