Mine is a whole house generator connected to the house electric system. It is scheduled to exercise once a week then send me a text and email. It does so without fail. I haven't had to actually use it in a power outage yet, but I am confident it will perform as it should. The recommended installer did a great job.

Since installation in early March, the unit has fired up 5 time for various power outages. Most recently just two days ago when a neighbor's moving truck took out two utility poles for eight hours. The unit worked flawlessly during the outage much to the envy of my neighbors.

This is my second Generac unit, the first a 20KW on another property installed 4 yrs ago. The newer unit has a better exercise program and controls and the R end panel removes for battery access. This is a really big improvement over the older unit. The elimination of the outside 20 watt plug is a step backward. Overall it is good value, reliable, and easy to service and I am very happy with it.

We're about 6 months into ownership now, and have experienced 1 power outage. The machine performed flawlessly. We live in a rural area area where power is lost quite often due to storms and it's really comforting to know life is not interrupted because of that. That said, I wish to add the home surge protector was also a worthy investment. Thank you Generac.

I bought a 22kw unit for our remote cabin as a backup to random power outages due to storms. Install went as planned and we tested it several times and the generator picked up the load as planned. Considering buying one for our home. What a great peace of mind!

We had a generac generator at our last house for 7 years, no problems. We have only tested this unit so far, no power outages yet, but tests were good. Only one problem, the load shed modules do NOT work as advertised. The specs say it can "disable" a circuit while on generator power. It cannot do this. It can disable the circuit in an overload situation only. We needed this feature to disconnect our solar panels while on generator power.

Less than two weeks after having our whole house generator installed, a wind storm passed through our state and knocked out our power for three days. Having two 80+ year old in-laws with medical conditions living with us made the power provided by the generator a literal life saver. I would highly recommend the Generac generator. My wife says it is the best investment that we have made in the last 25 years.

My unit was installed in March 2016. Other than the weekly exercise period, there have only been a few times when the generator kicked in due to loss of power. There has been no problem with almost immediate replacement of power. There has been no failure to kick in. I'm very satisfied and happy with my purchase and dealer/installer.

Replacement unit for lightning damaged unit on my home. Great replacement. No problems. Just wish I had an indicator for service in my home. Unit is a bit hard to get to for my age. My last unit had that feature included in the original installation.

I bought a Genrac generator 22k for a great price. Their sales people were very pleasant and easy to deal with. The Genrac 22k generator is a sleek nice looking piece of equipment. It is very quiet when in operation and has a outside protected cover with a built-in thief key lock protection system .
