A few improvements would be to A make the insulation above the engine not fall onto hot exhaust manifold and B make the outside access panel a little more rugged to it doesn't break off so easily as mine did when the generator is being moved into position during install. The insulation is stuck on with an adhesive and mine was laying on the engine when we uncrated it new. No retainer or anything holds it in place. That is a real fire hazard.

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!

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 .

Overall a very good product and value. I installed it myself and the process was straight forward and intuitive. The only recommendation I have for improvement involves access to pulling and termination of the power wiring. I installed the 22KW unit - largest in the series - 100A wire. Based on the conduit opening size and location, pulling this size wire and landing it was not an easy task. Making bends where it entered the unit in relationship to the internal equipment shrouds located nearby was quite difficult and routing the wire to the termination points requires a contorsionist. Otherwise, this is a nicely designed unit.

The generator does its test every Wednesday at 1pm and is only on for 10 minutes, power went out for a couple of hours and the generator came on within seconds after the power went out and shut off when the power was restored, so far so good and now I won't have the wife upset when we don't have power, thank you " one happy customer"

We had a 16 kw Briggs which burned up during the August, 2016 floods. We moved up to a 22 kw Generac in hopes that we would see an improvement in both performance and reliability. When our electrician started pulling more wires than the B&S needed I started questioning him. Seems we can delay our A/C and save the generator, and home system, from the serious re-lighting strain. Ya learn something new every day and Generac certainly is proving that quality has no price !

Nice complete package. I found the instructions for installation confusing. I would have liked all the specifications for installation in one place or chart. Wire and pipe sizing chart would be nice. Runs great, works great. Other than weekly exercising, it has only come on one time for about 15 minutes.

Installed 22kw unit in October 2016. We are away for several weeks during the winter and we were always fearful that a power outage would result in catastrophic damage to our home and business due to frozen pipes. We also have a sewer pump/grinder unit that only has a capacity of 100 gallons. If we lost power, we couldn't use water without fear of sewage backing up into our house.. My electrician recommended Generac over the other leading brand and reviews backed up his opinion. So we had it installed. It took about a week due to the additional installation of two propane tanks. To date it has given us peace of mind when we are away. The mobile link has worked great allowing us to check the status of the generator when we are out of state. We haven't had any power outages as of yet, but I'm sure one will happen sooner before later.

Service beyond the sale was great though I was given some confusing information from the the company recommended technician who serviced the product post installation. The 22kw generator was set up with parts supplied with the generator and was set up by an electrician as part of my new home build. Long story, short, there was a flex gas line supplied by the company to be used to connect the generator to the hard pipe gas line from my propane tank. The tech told me in no uncertain terms that the flex pipe was inappropriate to connect the main gas line to the supply line as the vibration caused by the generator could cause the flex line to fail and should have been hard piped directly to the generator. The propane supplier disputed that theory and told me that vibration caused by a hard piped connection would be more likely to crack and lead to either a fire and or explosion than a connection made with the flex pipe that was supplied with the generator. Otherwise, so far I'm satisfied with the product and follow up service that was provided.

Purchased 22KW Unit in Jul 2016. Installation instruction were excellent. The unit has furnished power during two outages since installed and operated flawlessly. I would recommend this unit to anyone who, like me, lives in a rural area where frequent loss of power is likely. CLM, Vanceboro, NC
