Rated 5 out of 5 by from It really brings peace of mind, I have been really satisfied with my Generac. It starts and powers my house within seconds of an outage. The Generac employees have been very easy to work with.

Rated 4 out of 5 by from 38KV NICE, WIFI app not worth the recurring cost To be fair the 38KV has only been installed a week. I hope it performs correctly during an outage. The unit seems well engineered and the quality of workmanship looks good. The top of the unit should have just a little more taper to reduce the pooling of water on top. The Wifi finally connected after setting it up and a day later started communicating correctly without any other setting changes. With that being said, from what Information the connectivity gives you the recurring costs are NOT worth it especially after spending thousands on this generator and install. My home thermostat has more setting to interface with my HVAC system then the generac app and there are NO recurring cost. The same can be said for many home wifi units, garage door/cameras, speaker systems, and almost all kitchen appliances ovens, stoves, and fridges.

Rated 5 out of 5 by from Finally, got my Generac delivered I ordered this unit through a dealer on Feb 5, 2021, nearly 1 year ago. After multiple delays from Generac, the unit arrived January 23, 2022. The dealer installed the unit Feb 8th. Other than this delay of delivery, all has been great with Generac units. We had 18 KW, 1800 rpm, water cooled for 15 years. Upsized to this unit and gave the old unit to a neighbor for their use. I have been quite pleased with the performance of my Generac and expect the new one to provide another 15 years of back-up.

Rated 5 out of 5 by from RG03824ANAX Very impressed with the quietness of this unit. It is our second Generac. The first one is now 9 years old and has been trouble free. It is 27 KV. This new one, though larger, is just as quiet.

Rated 5 out of 5 by from 38KW Generator - glad with my choice! Very satisified with the 38KW generator bought - and was amazed on how "quiet" it is when turned on (the noise level is way lower than for smaler generators).
