The generator works

Love my new 22KW/999 generator! The first week it was installed I got to put it to use! A squirrel blew the transfer switch for our neighborhoods power! I was in the shower at the time and when the lights went out I thought oh no! But 10 seconds and I had power! The rest of the neighbors were out of power for 5 hours! Generator did it’s job!

Outstanding purchase

I live on the gulf coast were it is not if we have a storm and a power outage but when. I did a good deal of research before I decided on a Generac and was not disappointed when the install was complete. The peace of mind of knowing that I will have power when we have our next outage is worth every penny spent. Hurricane season is 6 months long and worrying about a storm gets old. The installers were professionals and did an excellent job. When we did the first load test you could not even hear the generator running inside the house.

Waiting for a Storm

I purchased the Guardian 18KW Whole House WI-FI Enabled Model. It looks Awesome and it kicks on every Monday at 10am for a test. The peace of mind it gives me is immeasurable. Every time there is an ice storm or a rain storm, I am not worried in the least that I will lose power. Just waiting for the storm ! ha ha

Works as Advertised, Smooth Transition to Backup Power

Like many, we just installed it to back up the whole house. The ATS works cleanly and efficiently. There is a couple second delay to engage when power goes out just as expected. This unit is 100 amp output and keeps up with most of our home's 3000 sq.ft. 2 AC units and electric tankless hot water. No one should ask that much of it. But we do and the only gotcha in our setup so far is the hot water heater drawing over 100 amps. (the generator protection mechanism engages properly shutting it down, no distress to it or the house, resetting is easy, which is a plus during a black out) So in backup mode, we have to kill one of the 3 40 amp breakers to the hot water heater. We are going to get the WiFi enabled smart breakers so we don't over tax the backup generator. But I am impressed that this little guy does exactly what it is designed to do, easy to use, and pray its longevity is as impressive.

Power and Convenience when you need it most!

I live in unincorporated New Lenox; seems we lost power a lot. (Older Section, Above Lines, Transformers) Now retired with my wife, don't want to be messing around with extension cords, portable generator that won't start @ 3:00AM in the morning (plus No gas). After talking to Baker Electric @ the Tinley Park, Illinois home show, I was SOLD! (And I went to buy windows, so go figure). The Generac is the CADILLAC of Whole House Generators the way I look at it. Generac's sale's representee's are extremely helpful, responsive, and informative! Plus, the 10year warranty helped persuade me too. WELL SPENT MONEY!

Think hard if you really need a generator!

If you live out in the country, you will have to do all the installation yourself and don't try and use the generic web site or try and talk with anyone at generic, you are on your own. If you can find someone that installs them, they might give you some free advice. I got lucky! If you live in a large city, you might have better luck finding a dealer, if not you are on your own.

New Installation with 40 hr Outage

This 14 KW Generator was installed on 12/8/21 by (3) installers with completion after about 6 hours. The installation looks professionally done. The generators WiFi module was connected to my WiFi and a simulated outage was successfully completed with the generator automatically being energized. The simulated outage was recorded on the Mobil Link 'Status' page. The Mobil Llnk App was showing a 4 - 6% signal strength. Three days after the installation, we had a 40 hr outage due to high wind and the generator performed flawlessly, but the WiFi Mobil Link, not so good. The operation of the generator during the actual outage was not recorded on the Mobil Link status page. I checked the signal strength of several of my devices at the generator site and they all picked up a full signal in comparison to the generator WiFi Module's 4-6% signal. A subsequent call to the installer resulted in my being redirected to the Mobil Link 855 number with a request to pass anything I learned back to the installer for their education. The first call to Mobil Link concluded with a recommendation that I needed one of their recommended WiFi extenders because the generator WiFi Module doesn't work well with dual band WiFi systems such as the GoogleNest mesh system I have. After purchasing and installing a TP Link N300 extender, I upgraded my signal strength from 6% to 20% for the WiFi Module and with a recent update to the Mobil Link app increasing it to 28%. Since this was still well below the 40% signal strength that is recommended in an article at the Mobil Link Tech Support website, I called their Mobil Link 855 number again with my previously opened case number and was told they didn't have any further recommendations to improve the WiFi signal and 28% was probably good enough to avoid disconnects. I think this should have been a turn key installation with the installer assessing what is existing at the proposed installation site, quoting what is required to make the system work as recommended (including the WiFi Module) and then assuring it does so when the installation is completed. I think there needs to be a WiFi antenna external to the generator housing, but apparently Generac doesn't yet.

Installation and testing

Fairly easy to install with instructions and wiring diagrams. I only tested it once and it transferred over fine. It has exercised twice for 15 minutes. So far it has passed the tests fine. One thing, I don't know what king of oil to use in the future as it is not written in any of the manuals.

This was a DIY project that went well.

We purchased a 14KW model generator and automatic transfer switch with distribution. Install and electrical was DIY while the gas connection was contracted. Coordination with an existing solar power system was accomplished and fully tested under load. The system is now standing by exactly as desired and fully inspected.

We are pleased with the Generac.

Since the Generator was installed, we have not lost electrical power to our home .However, we expect the Generator to perform as advertised. We were surprised at the number times the installer had to come back to get the Mobile Link feature operational. All in all, we are very pleased with the price, product and warranty.
