This is my second purchase and it has many new features.

Recently purchased my second Generac getting a bigger unit for whole house power. The Generac unit I previously had was half the size of my new unit and had provided backup power on several occasions, the most was for 41 hours running uninterrupted. It has been the best investment for my home and an additional benefit was when I notified my insurance company of the installation they noted that I would get a credit on my policy for having the generator and that it would also add value to my home. IT WILL NEVER DISSAPOINT YOU!

One small drawback

Just had the Generac model 7226, 18 kW home standby generator installed and am very pleased with it. The one small drawback is the Status LED indicator light is on the right side of the unit, away from my street view. The unit should be designed to move the Status LED indicator light to the left side of the unit if needed to view it from the street.

Peace of mind

They just installed today .. The installers were hear as scheduled and went right to work .. Knew what they were doing .. Was only without power fir maybe 20 minutes during the hookup. Generator started right up ... Just knowing we won't be without power during power outages gives me much peace of mind ... Happy with the generator ...

Peace of Mind

I purchased and had the Guardian 22KW installed on 041615. We rarely have power outages in our area but I had the Generac installed specifically for Hurricane season. Lo and behold, the day after my generator was installed our area experienced a tornado and power was out in our area for 9 1/2 hours. Three days later we had another bad storm and the area power was out for 6 hours once again. The Generac did just what it is supposed to do. Within seconds of the electricity being disrupted, the Generac kicked on and powered everything we would normally be using for the entire time. We never even would have known the electricity had gone out if we couldn't hear the generator running outside and the few seconds the house went dark before the generator sensed the problem and started automatically. Our generator runs on propane and after being on for close to ten hours, hardly even budged the propane gauge on our 500 gallon tank. It did not even register a gallon used to power the unit for that length of time. We are extremely pleased with our new Generac 22KW and would highly recommend it to friends or family. The professional installers were very efficient and thorough. They did a beautiful job and even completed the installation even though it was storming outside before they were finished. We have had the generator running for only eleven days and it has powered us for (16) very unexpected outage hours. Apparently we got it just in time.

Nice looking unit with all the master features.

Our generator was installed August 6, 2020 but we are waiting on the propane tanks to be installed before start up can occur. There seems to be a shortage of tanks right now. Jason II, Eli and Johnny from Holly Electric did an excellent job with the installation.

Good Machine but With Issue

Just over a week or so ago I purchased a new 14 kw standby generator, and had it installed by Pine Tree Standby Power - They were excellent from start to finish - Generator wise, it seems to run well after test trials and has exercised twice since install - My heartburn comes from this - One of the advertised features of this unit is the ability to remotely monitor it via its onboard Wi-Fi module and a downloaded app on your smart phone - This was important to me as I am handicap and it is hard for me to get to the generator - A great feature if it actually worked - I must preface comments by saying I am retired from a 40 year career in network engineering so I know just a little - After hours of attempts to setup the generator Wi-Fi, all failures, I concluded that the unit was not communicating with the network - The unit is no more than 15 feet from the router, and yes I was sending 2.4Ghz signal to it. I began research only to find that this is a VERY common issue for this unit - I called support and got a gent who was very polite but lackluster - After making me walk through EVERYTHING I had already done (and told him so) he concluded the generator was not communicating with the network and wasn't going to it seemed - His suggestion was that I look into a Wi-Fi extender to increase signal or get a different Generac Wi-Fi module - After research, I learned that Generac has known about the weak Wi-Fi module issues yet let them exist and still keeps plugging the feature in ads and flyers - Yes I could buy a network extender. Yes I could order the replacement Generac Wi-Fi module from their website at a cost of over over $300 - BUT why should I have to pay to make the 14,000 dollar investment run as advertised? Any distance over 20 feet from the router and the supplied module will not get/hold connection - If you are thinking of this unit for the remote monitoring look elsewhere - As the unit is only two weeks old I am seriously thinking of calling the dealer to refund me, take it lout, and then get a more reliable one

Standby generator

Living down south we deal with storms half the year. I was tired of pulling out a portable generator and having it not start much of the time. I had this installed and a week later we had a storm which knocked out the electric at 2 am. It was nice to hear my generator kick on and the hum from it put my right back to sleep. Best investment for my home.

22kW Standby generator

I love my new generator. We have only had it for a couple weeks now and it has already done its duty twice. The lights flicker, hardly noticeable, but I go outside and find my generator has kicked in because the power has gone out again as another strong storm goes by. Wisest investment I ever made - I can hardly wait until winter!

Whole-house power at a decent price.

Purchased and installed 18 months ago. LPG fuel, whole-house coverage. To date it has powered our home for a total of 57 hours, with the longest single run being 31 hours. We live in a heavily-treed area where most power lines are above ground. Any time there's a windstorm, there's a good chance of a power outage. We depend on electricity for our water supply and to keep the house warm and pipes from freezing. Very pleased with the reliability and capability of this unit.

UPDATED REVIEW ( STILL THE BEST GENERATOR ON THE MARKET )

LAST MONTH, CHRISTMAS EVE MORNING I BELIEVE WE HAD A VERY SERIOUS COLD FRONT COME THROUGH TENNESSEE, 18 & 20 BELOW IN SOME AREAS, AND FOR TENNESSEE THAT’S PRETTY MUCH UNHEARD OF. WE WERE HAVING ROLLING OUTAGES EVERY 30 mins. WAS SUPPOSED EVERY HOUR, IN EACH GRID, MY GENERAC WAS PREFORMING FLAWLESSLY, BUT I WAS STILL CONCERNED ABOUT OUR APPLIANCES, HAVING JUST BOUGHT THIS HOME BECAUSE OF THE FLOOD THAT HAD CAME TROUGH WAVERLY, TN. ABOUT A YEAR AND A HALF EARLIER, WE HAD LOST EVERYTHING AND HAD TO REPLACE WITH NEW IN THE NEW HOUSE WE PURCHASED, SO I WENT OUT TO THE A.T.S AND THREW THE BREAKER, AND OUR 18KW GUARDIAN SERIES RAN LIKE A CHAMP !!!!!! WE HAD TO REPLACE ABSOLUTELY ZERO APPLIANCES, OR THE 2yr. OLD CENTRAL HEAT & AIR UNIT !!!!!! I CANNOT SAY ENOUGH POSITIVE THINGS ABOUT THE GENERAC GENATOR AND THE GENERAC COMPANY, AS WELL A.E.C. LLC ( ALPHA ELECTRIAL CONTRACTORS LLC. ). THIS GENATOR SAVED US THAT DAY !!!!! I RECOMMEND THE GENERAC GENATOR TO EVERYONE, THEY ARE REASONABLY PRICED & A.E.C. LLC. Keith Geoff, AND ALL THE GUYS THERE, YOU WON’T FIND A BETTER GENATOR OR A COMPANY TO DO THE INSTALLATION ANYWHERE !!!! THANK YOU GENERAC & A.E.C LLC. !!!!!
