This is my second generac unit. The new one is much better than the first. The steel case on the first rusted very quickly here in S. Florida. The battery charger on the new unit was a terrific addition but did require some new wiring that the first unit didn't need. So far no problems (in use for six months).

Mine has worked exactly as I had hoped it would. That is, it only turns it's on Saturday at 2pm to perform its weekly check... Haven't had any power outages yet requiring its service but it has given me a comfort level knowing it will come on and my home will be powered since I have a disabled son here 24 hours per day.

On 1/02/2017 we lost electricity at 8:25 AM just as I began to work on an important project in my home office. In 7 seconds my General 22 kw generator turned on, restored power to all but a/c systems. After an additional 20 seconds the first a/c system came back and 15 seconds later the next one turned on. I was able to work for the 3 hours that it took for service to be restored. The generator is just outside my window and the sound is similar to a riding lawnmower at idle! What 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.

We purchased the Generac 22 kw Guardian system in October of 2015. I installed it over the next several months as I had the time. A few months later we had a power outage for about 5 hours. When the power went off the Generac powered up in about 15 seconds. Wonderful! I am writing this review 2 hours after our power has been restored this morning January 25, 2017 at 8:45 am. We had a very bad ice storm on January 14, 2017 and thousands of people have been without power. Many still have no electricity as I write this. We gave this generator a very good 10 days and 9 hour workout. My wife and I highly recommend this generator.

On returning home one day last summer we discovered the electrical power was out due to a storm. It was a really hot day. We had guest coming that evening. Thank goodness for the Generac generator. The generator worked as advertised. The house was cool. The sound of the Generac running was barely evident. THANK YOU GENERAC!

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.

We love our general. It was one of the best investment we made for 2016. We should done the same in New York when we lived there. We recommend every one who lives along the Gulf Coast of Florida, Alabama, Mississippi, and Georgia to get one for their home.

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 purchased the generator because of electrical outages during storms. It has provided backup power 3 times in the past six months. It's performance has been great. Most importantly, we are far more comfortable knowing we have reliable, sufficient backup power if a problem occurs.
