Will this size be large enough to power up my whole house in case of power outage

Asked by Dave March 19, 2021

Answers

The 22K Generac is the most popular generator probably because 200 amp electric panels cover most houses. To guarantee if it works in your house more info is needed such as size of house, location and if it is total electric. Most Generac dealers will due a free assessments and price to install.

We had the GENERAC professionally installed and had had the gas company install the gas line. Testing the GENERAC, it powered our whole house, garage, barn and workshop. You can hear the GENERAC running but it is not overly loud. Using a WiFi extender, I was able to connect it to my iPhone. Home Depot shipping was great, arriving on the day it was promised. The delivery men even placed it on the concrete paid I poured for it. Thanks Home Depot for a great product and shipping.

No more lost food and electronics, just peace of mind
The whole house generator works exactly as advertised. The available whole house surge protector from SPS is wonderful. I can now get rid of all the other ones scattered around the house protecting various electronics. Specialized Power Services is customer focused and did an excellent job installing and explaining its features. Two refrigerators and a chest freezer no longer are a concern when the power goes out from falling trees and best yet - our spa is useable. No more gasoline powered generator, attaching it in the rain or snow, to run some products e.g. furnace and a few selected items.

Just survived snowmageddon...Texas
February 2021 in North Texas and record low temperatures with electrical providers unable to supply power reliably, all we had was our Generac 22kW to survive the -16ºF week. We have an 'all electric' house with no gas appliances. No fall back position except... There is no better sound than the auto startup of your lifeline. The instant switchover on release back to electrical supplier means no flicker or resetting clocks. The power supplied by our Generac is virtually the same as that supplied by your power company - true sine wave output means no fluorescent light flicker or refrigerator hum. All in all our Generac ran over 100 hours over the week and supplied us with a true lifeline. We could not have survived at home without it.

No more warm beer!
After living in the Cape Fear area of North Carolina and experiencing various hurricane outages up to 10 days, we are glad we decided to install a 22K Guardian. The ability to live somewhat normally after a hurricane is a relief. No more hot, humid days and uncomfortable, dark. boring nights waiting in the heat for service to be restored. No more spoiled food. No more cold water showers. No more looking for sold out ice and supplies. No more warm beer! Did the load test today and no problems. We are ready!

A proven product that provides worry free peace of mind
We live in a rural area that has experienced several recent power outages. The derecho storm that affected the mid west this summer left us without power for five days. Since our install after the storm we have not been without power thanks to the automatic and reliable transfer to our Generac power source! Our qualified dealer installation was timely, and a neat job, done with perfection. We highly recommend Generac!

Great Job by Mohrmann Electric
Received about a half-dozen estimates before deciding on a 22KW generator and Mohrmann Electric to handle the installation. Felt very comfortable speaking with Fred, the owner and his son Dennis, about our needs and some other electric supply issues we had. They gave us a very fair price for the generator and installation (some estimates were for THOUSANDS more); were very knowledgeable in understanding our needs; laid out in detail the installation plan and timetable; met the original installation plan and timetable; and did an excellent job delivering EXACTLY what they promised. We also had them upgrade our circuit and electric panel to 200 amps. We were also extremely surprised by how knowledgeable and detail oriented their administrative staff were. Their administrative staff understood the entire generator, electric and natural gas plumbing installation process and the local permit processes in Huntington NY. They called in advance to schedule all the work; always told us what the next steps were and when they would occur and handled all loan application and billing needs. Never dealt with such a knowledgeable and professional administrative staff. Special thanks to Laura and Meg who we dealt with most of the time and also Theresa. Fred and Dennis - you have a wonderful organization.

Ran Great During Hurricane Sally 9/2020
In two year's time, other than the monthly tests, our generator had been running for less than two days, total- then Hurricane Sally hit our area. 200,000 homes were without power. Hundreds of telephone/electrical poles were snapped like matchsticks. Thanks to our Generac Guardian, our home had power for 70+ hours. It easily powered our 2,000 Sq. ft. home. Two of our neighbors bought Guardian 22KW generators, just like ours, after we recommended that model, so there were three Generac Guardian 22KW generators, less than 1/4 mile apart, that ran 70+ hours with absolutely no problems. It immediately shut down when the power grid returned. We could hear the gasoline generators of a few neighbors still running hours after our electricity returned as it was still daylight.

This will do all I need in a hurricane power outage.
I had been taking gas cans and getting them filled to run a 6500 watt generator for years during power outages from hurricanes, When i read up on Generac whole house generators and talked to some friends that had them I was sold. When it was started up and tested for the first time yesterday it was a good feeling, The unit ran perfectly and ran all of the utilities in the house including the air conditioner. It is a nice looking unit and will serve my electrical needs for years.
