The generator works as advertised

We just finished the install and 2 days later lost power. Everything worked as advertised and we were pleased to have a working generator for the 2-3 hour period while our power was down. Haven't really read and learned about all of the features i.e. wifi yet but will shortly. The install went very well and we were pleased with the communication, completed work and clean up.

Great Unit, worked the first time!

Overall this unit met all my expectations. It worked the first time it was turned on transferring to the load correctly and shutting off. The unit looks good next to the house and has very understandable features. The unit has just been installed so will have to see over time about reliability. I would recommend this product to anyone having reliability problems with their local electric utility.

clean design

The only reason I gave four stars is, we have not had to use our Generac since it's been installed. Though I'm sure it will perform as it should. The test run that Samual (crew leader) did was very precise with lots of information on how it should work. Mathew was an all day crew worker and didn't leave until the job was finished. The actual unit has a very clean line look, which doesn't make it unsightly. Thank you Holly Electric, for the ease leading to our installation date.

Peace of Mind

How do you spell peace of mind? How about G-e-n-e-r-a-c. We installed the 22kw model a couple months ago, and I rest easy, knowing my generator is standing by in the event of a power emergency. Each week the unit fires up for about five minutes in test mode, reminding me it's ready to go. We installed the generator as part of a swimming pool project, so the unit sits nicely among the rest of the pool equipment - compact and out of the way. I can't imagine owning a home without a backup generator, especially with our aging grid system and the looming threat of cyber attacks.

Excellent Features

Recently had the whole house generator installed. The employees doing the install were great and very knowledgeable. I did lose power about a week later for a short time and the generator came on exactly as it should. Would recommend this generator and Metro Electric to anyone in the market.

Post Installation

I just finished installation of a Generac 22kw 70422 unit to replace a 10 year old Generac 20kw model. The installation went very well as I was using my existing ATS. The wiring diagrams could of been a little clearer identifying where the wires needed to land and how many the unit actually needed to function properly. Four of the five terminals were clearly identified the 5th wire required a little research. It would have been helpful if I would have know the gas line from the unit was 3/4 inch rather than the 1/2 inch used by the 20kw model. The WiFi instructions were as little cloudy but after the calling the helpline I received outstanding service. Hopefully this unit will last for many years! I have installed about 6 of these units over the last 10 years and the 20kw model I just replaced is the only one I have had issues with. I would strongly recommend Generac to others seeking standby power options!

Cleanly designed product with room for feature improvement

The installation and initial burn-in went very well. We ran our ground source heat pump in A/C mode to give it a good test and the 26kw unit was up to the task. We are confident that we can travel without concerns for our pipes freezing while we're away. It could be improved if there were a way on the App to configure it to send email to the owner when a new item is entered into the History Log. As I write this I note that the unit has been off-line via wifi for the past 10 days and I had no idea.

WORKS GREAT

Our generator was installed on Friday March 10th. The very next morning our power went out! The generator performed flawlessly! Our house and greenhouse stayed lighted and warm!! Everything worked as if nothing was wrong. Then when the power came back on later that afternoon the generator switched off just like we had been told it would do! We are very pleased with our investment!

Excellent product

The generator has performed flawlessly each time we have lost power. It's a great source of comfort knowing we have this backup at the ready. We were concerned in advance about how loud it might be, based on some neighbors machines, but our Generac is considerably quieter than we thought it would be.

Excellent Product

We are very happy to have our back up generator. It looks nice and works like a champ. It is so nice to have the peace of mind, knowing that in the event of a power loss, we will be up and running. Also, it will add value to your home for future resale.
