New to Generac world

a month ago
Veery difficult to review a standby generator because an unexpected power failure is real test. Wee bought our 26KW Generac last year and hasn't seen a power failure yet. In fact, been in this house for last 20 years and lost power twice and not more than 8 hours either time. Generator looks well designed and exercise as programmed. Not very loud and sending notices via text messages via wifi connection is awesome. I hope I never needed to use it but it comforting to know that we have a standby generator just in case we loose power. Specially when my wife's health conditions do not allow to be without power for extended period of time. The mobilink app is good but should not have to a price to edit exercise schedule. I paid but didn't like that option. Overall I am happy so far.

love power outages

a month ago
i bought my generac 14 kw generator in october of 2021, so I think I can give it a fair review now in october 2025. The generator has been flawless, except last yr. on a sub zero afternoon it wouldn't start to run it's weekly maintenance cycle, but that's the only hiccup I've had with it. I would highly recommend this generator. Ive lost power countless times and it's always come through. I also like the fact that this model has the hydraulic valves that don't need adjusting.

An absolute dream

2 months ago
We live in a very wooded suburb of Boston. One might think that living 30 minutes outside of a city isn't the type of place for power issues, but our town is densely wooded with lots of tall mature pines everywhere. Whenever there's any kind of storm, be it a thunderstorm in the summer, a nor'easter or ice storm in the winter, we lose power almost guaranteed. The power company in our area is also extremely slow to restore power. Any outage guarantees at least 12+ hours of downtime, with many outages lasting 2-3 days. We got tired of spoiled food, no heat, and just huge headaches. We got this 18kW Generac 7226 installed by a local dealer last year, and it's already gotten us through two multi-day outages. It's so nice to not worry about our refrigerator and our heat in the wintertime anymore. We're able to continue our daily lives as normal while it just hums away outside powering our house. The automatic transfer switch takes care of switching back to main power after immediately once it's back, even in the middle of the night. If you're on the fence, go for a Generac. You won't be disappointed.

Yes, I recommend this product.

Good Machine but With Issue

2 months ago
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

No, I do not recommend this product.
