As it turned out, our Generac generator had a defective control panel. The defect prevented the generator from properly switching the house over from the electric company's power supply to the generator's power supply. So, the first time the power went out in a storm, the generator motor activated, but because of the defective control panel, we remained without power. That caused us some real concerns and worry, a long 3:00 a.m. conversation with our electrical contractor, and two warranty visits to get the new control panel installed. Since then, the generator appears to operate correctly. The power went out one other time, and we had no problems. Just the same, we have a small remaining "trust" issue with the unit. A manufacturer defect can occur in the producing any product; we certainly understand and accept that fact. Yet both the manufacturer and the unit installer would do well to test for control panel defects. On the plus side, Generac fully stood behind its warranties. All in all, we like the generator, and remain optimistic that it will give us many years of reliable service.

My wife and I are in our mid seventies, and it's a nice feeling knowing we won't be without what we need when we need it. This is here for us, and we can't ask for anything more than that. One of the best investments we made for ourselves. Thank you Generac.

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.

Apart from the weekly tests we have had one opportunity to see the generator in action when a nearby transformer failed. We had full power restored within a minute, and seamless transfer back to utility power once the repairs were complete. My only complaint is that as an engineer, I'd like to get more data from the weekly tests. All I get is "It started, it ran, it stopped". I would like to see logs of fuel consumption, oil pressure, temperature, and generators output. I've asked about this information but my requests went unanswered.

This is a very good product, the only complaint I have is It never came with a sticker for my elec meter that says there is a secondary source of electricity, just in case a firefighter pulls the meter in an emergency, please send me a MUST have sticker.

I think the washer will be great. It has good features for different uses, however, the first time we used it the high pressure water hose failed. Blew a hole in it. The company was quick to replace it, (but just saying.) Don't know if this is a common problem or just an odd occurance. Will know more after additional use.

This is my second hold house I have purchased, both be Generac. My first purchased preformed well, was an easy to install with straightforward institutions. I wouldn't recommend most people to do that, only if you have skill set to do so. The new control center setup is great update along access panels that easy remove for installation. Thank you Generac making the best full house generation on market, Marwood

Our 22KW has been installed a few months and already run a bit over 60 hours so enough use cycles have been experienced to let me recommend this unit to anyone looking to protect their home or business from periodic, even frequent, power outages. The only points keeping me from providing an unreserved five star rating are these: The unit looks fine: functional and solid. It is loud! Focusing the noise away from your house/business should be a consideration in placement. (Probably many generators of this size and construction have similar issues but I am more aware now!) The whole house transfer switch is critical and buying this as part of the generator bundle is a great value. No matter who you choose to do the installation (from DIY to independent contractor to Generac Recommended), be aware a proper installation requires expensive wiring; potential ground excavation; and a very competent electrician comfortable in all aspects of electrical wiring; general contracting and local building codes. This too is something any generator/transfer switch install will require, but be very aware installation can be a SIGNIFICANT cost of the total project. Finally, I don't have the add on unit which allows internet alerts (I am considering this additional expense), but I think it would be very convenient. The unit functions with minimal maintenence and has smart diagnostics, but being alerted remotely would be a real plus. I think this functionality should be built into the unit in today's age at some marginal added cost. (Adding this to every unit should bring the cost down to almost nothing for the manufacturer.) Overall, very pleased with the unit, build, design and value. Were I to make a purchase again, I wouldn't hesitate to buy from Generac. (In my location and situation I would/should have done it sooner!) I actually overbought for my situation. My home would likely work fine on a 16 KW, but on advice from knowlegable friends, it is always better to "overbuy" and not tax the generator than risk running at 80-100% capacity on full normal load. There are also some benefits to certain units. Shop for your needs now and in the future. This should be a great long term investment in your piece of mind and your property. Good luck!

Several of my friends have one and has never let them down. It has now given me peace of mind when I leave the house as I have a sump pump in the basement and with the new building code,, all the water goes there. They only drawback is the installation cost. Can't see how it cost almost as much as the generator and it takes them only 3 hours to install.

I truly can not totally review. The unit was installed on time and in a very professional manner. It tests itself every Monday and there are no issues. I have not had a poer outage, since the installation and would have no way to reate the unit until I have one. THANKS RICK
