Don't have operational time yet but all went very well with install of 22Kw and transfer switch that we placed inside the garage. Startup process proved system easily took the house without issues. Only two people (until a storm hits :>) ) and 2600 Sq Ft place. Write another review when the system is needed/used for the first real event.

Very impressed with performance of this unit. My wife has Alzheimer’s and we don’t have to worry about power outages anymore. An outage used to be very difficult because we’re on a well and septic system and it’s so nice to have all the other conveniences as well.

We had been researching stand-by generators for our home for the past two years and received two quotes from Generac Dealers in our area. The quotes were comprehensive and thoroughly explained. The dealer we chose completed the installation on time and as promised with quality workmanship from a 3 person crew. We are exceedingly happy with our choice of product, its performance to date and most particularly with our choice of dealer and the support they have provided. We would highly recommend this product and in particular Miskow Generators & Electric.

Shortly after the generator was installed, the power went out. I was just getting ready to leave for an important engagement, but my car was in the garage. I would not have been able to get out of the garage if not for the generator coming on and restoring power to the garage door opener. The power was out for almost 2 hours.

Nice looking unit. Noisier than I though it would be. Install took longer than it should have due to installer showing up with out necessary parts on a Friday and then had to wait till the following Monday to finish. Once installed unit fired up promptly and the "simulated" power outage had the unit start and within a few seconds the house had power. Obviously won't know how well it really works until an actual emergency and hopefully it works as promised. Wi-Fi set up SUCKs big time. NONE of the provided booklets explain it properly. Finally found a manual on-line (by Generac) that explained it. Why wasn't this manual provided with the paperwork? Wi-Fi still doesn't work and I'm not entirely sure why? Weak signal probably. Unit also a USB capability to update firmware but again NO manual explaining how that might work.

After several months of researching various generator brands I concluded that Generac was far superior to the others, especially when price is a factor. About seven months ago I finally made the purchase. I purchased a Generac 22kW standby generator with an automatic transfer switch included. We live in a rural area and have used the generator several times. Six seconds after the power goes off, like clock work, the generator comes on. Our special needs daughter lives with us and that fact alone makes a generator almost necessary. We could not be happier with our generator. I highly recommend a Generac generator.

Finally made the leap and had the 22K installed for our home. Product appears to be well made and will provide all the necessary power to keep our large home up and running. We have required durable medical equipment and power is a must!! Installer was knowledgeable and meticulous. Two transfer switches, generator and one power modulator as well as buried power and gas lines and you can't tell he was ever here. Generator ran its weekly test right on schedule. We are ready for "old man winter"

We installed this product, waiting for final startup. The generator has a 100 amp breaker yet is sold as a 22kw whole house backup. Granted that we probably don't peak over 100 amps very often but I was not clear that the product was limiting itself.

The generator has performed flawlessly each time we have lost power. It's a great source of comfort knowing we have this backup at the ready. We were concerned in advance about how loud it might be, based on some neighbors machines, but our Generac is considerably quieter than we thought it would be.

We just installed the unit. Test results were good, not able to give 5 stars yet as unit has not had a chance to perform. I’m confident that it will be fine. Was able to get good pricing from local retailer, with added rebate. Professional installation went well. Am very pleased thus far.
