Rated 5 out of 5 by Very neatly installed; everything easily accessible with great options . This unit was chosen for its "simplicity" along with the great options for operation e.g LP adaption if needed; battery block heater/oil warmer. As well the size is perfect for homeowner use and siting. Maintenance is simple also as per a gasoline powered free-standing unit - this unit is hooked directly to the natural gas feed to the house.Price is totally competitive.The unit was installed by Vibe Electrical coordinated with a new furnace and A/C by my dealer - a seamless installation. All in all a good experience. August 21, 2014
Rated 5 out of 5 by Excellent product. July 2014 we replaced are old unit of 20 some yrs. with a new unit,and the old one was still working. This unit gives you such peace of mind knowing I will not be without electricity, We have 3 sump pumps in the basement and if the electricity were to be out we would have a horrific flood in the basement,no water to drink. bath. or flush toilets and of course no lights. We greatly appreciate this product. Thank you Generac. August 1, 2014
Rated 5 out of 5 by This was a lifesaver! During our last storm, our neighbors lost power, but thanks to our generac generator we were able to enjoy the comforts of our home.Best investment we ever made! July 16, 2014
Rated 3 out of 5 by Not reliable We've had our residential backup unit for about four years.It often doesn't start at all in really cold weather (it's supposed to run automatically for ten minutes once a week). We have the service people out when we notice this happening, but that hasn't seemed to help. I don't know if it's been this way since it was installed, but we've definitely noticed it in the last couple winters.We just had our annual inspection and got hit for $600 for a new controller board because the choke supposedly wasn't operating correctly.All in all, if doing it again, I would seriously look at other brands. We went with a terrific local dealer who has done a lot of work for us and our employers. No problem with the dealer. But I do have questions about the hardware's reliability. Cold weather is probably the likeliest time for us to have a power outage, and we're not confident any more. July 14, 2014
Rated 5 out of 5 by This product is very reliable! I purchased this product in 2009 and it has not failed me yet.I love the fact that it runs on natural gas instead of gasoline, this fact makes it very reliable! May 11, 2014
Rated 4 out of 5 by This product is great to have because its automatic no need to do anything when you loose power works good when functioning properly. must make sure to do regular maintenance on it periodically. make sure it exercises weekly, check the battery semi-annually after the first year and manually transfer to the generator power to test regularly so you won't be disappointed later if there is an issue.

Rated 5 out of 5 by I Love my Generac I just recently purchased a Generac Guardian generator, and can't wait for the power to go out, so I can see how wonderful it works. March 24, 2014
Rated 4 out of 5 by Happy so far I've had this unit a couple of years, and has been good. However since it has seen this sub zero temps arrive the weekly start up has not happened 3 times. I had to manualy start up the unit. with the help of my installer [ very helpful ] via the phone . February 10, 2014

What is the model number of of the correct regulator that is required for the propane version of this generator? Preferably a Maxitrol regulator since it is the brand that Grainger carries... Thanks from the Dominican Republic.

Answer: 
We can determine the correct regulator for you. We will need to know the outlet pressure from your LP supply before we make that regulator suggestion. If you get that info, call Grainger's Techncial Product Support Team so we can get that regulator item number for you. 800 472 4643
