Proud owner

Easy to assemble well explained instructions. You can see and feel you have a solid well built piece of equipment. Started without issue however was louder than anticipated or had hoped for. Peace of mind knowing that my family will be comfortable through power outages thanks to Generac

Keeping our home livable post Maria!!!

Live in San Juan, Puerto Rico. Bought the unit 1 and a half years ago, but have been using it daily since Irma and Maria hit. I don't have transfer switch installed, so i am using cables going out of the generator straight to the equipment i am using. Powering four refrigerators, two of which are for neighbors, also two fans, two tvs with DVD player and washing machine, even wife has been able to blow dry her hair!!!! Situation is complicated by the destruction of the hurricanes, but this machine and its reliable performance is keeping me sane!!!! I can get upwards of 12 plus hours on a full tank. Easy maintenance and although it makes noise, it is reliable, powerful and great value. Would definitely recommend.

It has what the average household needs.

Only time will tell if it holds up well over the long haul, or if the investment was a poor decision. Realistically I don't believe it is meant for heavy duty service, but if taken good care of, and with only emergency duty, I will expect a long service life (many years) of reliable service.

Unstoppable

Purchased about 4 years ago During power outages and I get a lot as I live in remote area I run my A/C 3 deep freezers. And 3 frigerator freezers also my well. Plus lights and power equipment if I'm in wood shop Quite the machine I know gas tank will run at least 14 hours I never shut off just refill with gas as it doesn't splash out with the filler screen Definitely worth it

Post Hurricane Irma life saver

My brother in law let us use his generator for a few days after we lost power during Hurricane Irma. After 5 days without power, I bought this Generac unit at home depot and it has made living without power palatable. I was very impressed with the features provided -- the hour meter and service schedule by hours; the electronic start; the 8 gallon tank; and a bunch of other benefits not found on the other units on my street.

real nice generator

I bought this generator at the suggestion of my contractor. He knows what I needed. The delivery was simple. Though you will need four men to unload if you don't have a lift. It was delivered in good shape. It was easy to put together, though the print could be larger (need a magnifying glass). It took some figuring out. It started up super easy. Haven't had to use it yet, but am confident it will do the job.

Professional Quality

Bought this unit during a major power outage following a wind storm. Easy to set up, but unit didn't like full choke setting to start in high temp. Used 2 120V outlets for my house. One to connect to a strip to power freezer, modem & router in basement. Also ran sump pump b4 connecting to freezer. Connected 2nd outlet to strip on 1st floor to run fridge, LCD TV and fan. Let one of my neighbors use 3rd 120V outlet to run his fridge & freezer. Heard change in pitch of generator, when a compressor powered up. Unit worked without problem for 10½ hours, when commercial power came back up. Used about a full 7.2 gal tank. Very pleased with performance. It was a little noisy in the room next to the deck, where it sat, but not unbearable.

Good Basic generator with lots of power

I purchased this generator to run my house in-case of a power outage. It runs the 5 ton ac and everything else no problem. I did put a hard start kit on the ac but I dont think it was needed. We have four dogs so if the power goes out in the summer we have no place to take the dogs this gives us a piece of mind. My 7kw was good for the winter we have gas heating. Cant beat the price!!

Product assembles easily and generator started on first cord pull, but then...

I have rated the quality of this generator only "Fair" (a little below average) because of the two items that follow. The GP3600 generator is easy to assemble and it started on the first pull of the recoil cord. However, I ran into problems when I plugged in an electrical device: There was no power from any of the four 120 VAC, 20 amp, duplex receptacles (note: these receptacles have their own 20 amp circuit breakers). I had to call the store I bought it from and speak to someone who knows the generator and troubleshoot it with him. The problem was that the circuit breaker next to the single, circular 120 VAC, 30 amp receptacle needed to be moved from the "OFF" to the "ON" position. Once I flipped that switch there was power to all outlets. I did not know, and unless I missed it, there was nothing in the manual stating that the 30 Amp breaker controlled power to ALL outlets. There was nothing in the manual's startup procedure about this 30 amp breaker needing to be switched to "ON" so that power would flow to ALL outlets. I would recommend such a basic necessary item be addressed clearly in the manual. One other minor item: The plastic, zip-loc-type bags that the manual and warranty came in were very light grade plastic. I usually store the manuals for all of my power tools in the zip-loc-type bags they come in right in my shop near the tools themselves. So it would be nice if the bags were a little heavier grade plastic.

Great job, but heavy and loud

I have used one of these for a back up generator for my house for 5 years and it does a great job, but I have recently purchased and installed a stand by unit 22kw which is awesome., There are a few things that you need to know before purchasing this unit, it is heavy and I have to use a tractor to haul it from my storage shed to the meter to hook it up, also if it is raining I have to wait until the rain slows down because the connections are open to the elements. the only other thing that pushed me to get a stand by is this unit is really loud. I think if you know these things up front and are ok with them then this unit does a really great job providing constant power when in use.
