    • Very happy - money well spent.
Style: 22kW + 200A Switch
I feel sorry for those who received damaged/dented products, so I feel lucky that my unit arrived undamaged and in perfect condition. Having said that, I see how a flimsy layer of cardboard sheet attached to the base pallet may not provide much protection during shipping. Perhaps Generac should consider investing another $25 for a fully framed out protection. Speaking of delivery, my generator arrived 90 minutes later of the delivery window's upper limit. Since it was a Saturday, there was no-one available to talk to. Phone calls went to voicemail or calling the corporate number message was "mailbox full". Keep that in mind when you schedule delivery outside of normail business hours M-F. Prepare to buy a battery (about $60) and if you live in cold climate, a cold weather kit (around $200) to keep your battery and oild filter warm during winter. None of these are included. Currently working on hooking up the unit. Already ran the gas line and the wires to the Automatic Transfer Switch (ATF). I am giving a 5 star review in anticipation of everything working out as expected. Should something not, I will come back and update my review. 30 day update: We had a 1 hr unexpecred power outage. The generator kicked off and ran just fine. Automatically turned off once the power came back on. Very happy customer. 60 day update: Additional 2 power outages, each lasting about 8 hours. Generator worked flawlessly. Fired up in 10 seconds after the outage, ran smoothly providing electricity to the entire house and turned off automatically after utility power came back on. VERY HAPPY - money well spent. ... show more

    • It is controlled by a computer and NOT RELIABLE.
Style: 22kW + 200A Switch
I have owned a number of whole house Generators both diesel and propane that were reliable. If you want Reliability this is NOT IT. WHY? It has an onboard COMPUTER! It will NOT Run without the Computer. It WILL NOT START UNLESS IT IS ON Wi-Fi. Think EMP or Power Surge, either will knock out the fragile COMPUTER. Oh, they do sell a surge protector, but it won't protect the COMPUTER from lightning. Generac advertises you can monitor it from your phone. TRUE if you pay $70.00 a year for the app. The app wants to sell you filters and parts. If you want a generator for your mountain cabin or hunting camp you MUST have Wi-Fi to start it. If you want something reliable this is NOT it. This Generator with a COMPUTER was designed as a 7th grade science project that did not get honorable mention. Generac has lost its way. ... show more

    • Generac 70432 Home Standby Generator Guardian Series 22kW/19.5kW
Style: 22kW + 200A Switch
This is a great product. I had a qualified person to help install this unit. It was a little more involved because have two meters and the install required two automatic switches and some wiring issues to sync them together. Two days ago we had a major power outage and it work worked perfect without any issues. The system worked completely automatically with smooth transitions. I've waited some time to write this review because I was waiting for this to happen so I could validate an true test. Can't say enough what a great relief it has been having this unit. Worth the money, time and effort. ... show more

    • Acme was great merchant to work with!
Style: 22kW + 200A Switch
This was my third Generac purchase but my first from Acme Tools and I could not have been more satisfied. I contacted Acme initially after delivery to report a dent/scratch on back panel caused during shipping and was immediately refunded the amount necessary for replacement panel. One month later, I contacted them again because the initially reported damage had also resulted in damage to the wi-fi module that was not discovered until installation. After providing pictures, Acme once again refunded the amount necessary to replace the module. It should be noted they also provided for repair labor costs for both parts. ... show more
