We have had this generator for 5 months and it was installed when we built the house. We had some storms come through this weekend in Mississippi and were able to use it for the first time. We were out of power for around 1 hour while we used it. It cycles once a month per my settings and when power goes out you will have power from generator within 10 seconds. When power from utilities comes back on there is no loss of power at that time. Only when you loose power, the reason is generator must warm um before it takes a load. Awesome product and for the price and performance of this unit it's a winner for all.

My unit has kicked in multiple times since our purchase, be it minutes are hours. There is a minimum loss of power from outage to generator transfer. When power restored, there is no "blink" to indicate house power back on. Once a week , as scheduled, it starts up to run a five minute test.

This is the second Generac generator. I move away from the first that was a 20KW on natural gas. I had no problems with it during the 7 years it was in service. I installed a 22KW on propane as soon I got settled here. No problems with this unit in the three months since installed. In Oklahoma we are subject to power outages any time.

After ordering our generator I found out on the Generac website there is an offer I get the warranty extended 2 years if you contact Generac before you order. It seems to me if you buy the product new from an authorized dealer you should be treated the same.

This unit is automated to work as it does each week on a test run.. We have peace of mind just knowing its ready to serve our entire dwelling needs for us.. No individual effort needed on our part for the backup.. Its a great arrangement for us.. Thank you, Generac..

Purchased the model #6551 22kw system for my new house. Power interruptions in our area are typical and storms can bring outages that last for days. Haven't had a serious outage since installation but the unit cycles once a week for self-check. During installation the unit checked out against a full house load. My four star rating on features is due to the engine noise. Better muffling could help. During self-check the unit runs at a lower rpm and the noise drops by half.

This is a great product. Gives a homeowner a sense of security. The price was good and the explanation of the product was easy to understand. I wish we had done this years ago. I look forward to recommending this product to any friends or relatives who may be in the market to purchase.

We have had the unit installed for several months. We have had one incident when our power went out. After about ten seconds, the unit kicked on and everything worked as planned. When our regular power was restored, the unit shut itself off. My wife and I really are pleased with this unit. I would highly recommend this generator for any home back-up.

Works like advertised. I would recommend to anyone using LP gas that are not near a major road get a 1000 gallon tank. I purchased a 500 gal not realizing that they only fill to 80% or 400 gallons. I wish they had put a opening on the bottom of the housing to make run electric lines underground and up through the slab easy. It was hard to cut a whole through the base with a new whole saw.

The dealer installation was accomplished in one day with great care taken not to damage our lawn with wheel ruts. The Generac unit has run several days during power outages providing all the power we need for normal activities in our home. It does exactly as your ad claims. Thank you.
