This generator is really nice and powerfull.
Live in northern Florida, city of Ocala out in horse country and our power grid goes down at least once a month and we also are affected by hurricanes. This generator will power your whole house if required, starts easy, runs quiet for its size. It's real heavy to move around but manageable, I am using the 30A and 50A outlets in tandem to feed my single home electrical panel because the single 50A only gives you 12KW of usable power.

This is a great machine. I purchased it to run my whole house in the event I need it. It is portable and large and heavy. I bought a small trailer to mount the generator onto for easily moving around, hook it to my truck or ATV. Trailer has room for the big power cord and other extension cords. I purchase a bigger interstate battery to start it. I also use the battery for other things.

Nice machine. Build quality is excellent.
Purchased this generator in the fall of 2017 after a 4 day power outage. I haven't actually used it yet during a power outage, but have no doubts that it will meet my needs. ( I actually hope I never need to use it, but time will tell.) the intended use is to provide power to the house loads needed during a prolonged outage.
Our last power outage demonstrated that we needed more power to keep one of the electric baseboard heaters powered up, which had not needed to do during previous power outage.
The generator was sized to provide power to some of the electric baseboard heaters during a winter ice storm power outage, as well as provide some of the more "desirable" loads, such as the well pump, refrigerator, gas water heater, and basic lights.
The build quality of this machine is excellent. Nice welds, paint,source of frame components. It's a nice build. There isn't much to do, other than put the wheels and platform foot on, mount the handle, fill it with gas and turn it on.
It does come securely bolted to the pallet and if you can get it up in the air a little bit with a shop crane, or hoist, it will be very easy. Otherwise you'll have to do a little more work to get it off the pallet I have an overhead hoist, so with the supplied lifting eye, I was able to very easily do the work at waist level.
I filled it with gas, and it started up per the manual. No problems. Unloaded voltages were 124vac and 244 vac. I ran it for a few hours with a 3500 watt load, and everything seems fine.
This is a heavy machine, so don't be surprised at that. The designed method to lift at the handle and tilt forward could be awkward for a shorter person. There is also a lot of weight forward of the wheels, so if you do try to pick it up too much in the back, the weight will want to tip it forward and there is no protection if that happens. The stabilizing foot is to the rear of the wheels.
I will probably add a second set of wheels so that it rolls on four wheels and not two, and mount some type of anti tip protection on the front in case the weight does transfer forward. I wouldn't recommend rolling it around full of gas, that would be 85-90lbs of moving weight.
There must have been a design change to the front panel. My generator has the 50 amp plug on the panel front face, and not underneath, as some reviews have pointed out as a negative.
The manual is okay. Not totally inclusive, but definitely enough to get you up and running.
Where the manual is weak, and so is the website info, is that this generator had a "bonded neutral to frame". This is clearly stated on the front of the panel, so Generac isn't trying to hide anything, but the implications of that are not completely covered.
What a "bonded neutral to frame" means is that the frame "common", and "neutral", are at the same potential electrically at the generator.
This bond ,if carried into your house electrical system, will create a separate, second, neutral to ground bond in your house electrical distribution system. To preclude this, any transfer panel arrangement must "switch neutral" from the street, to the generator or you risk creating a second, parallel path, for current flow on the system ground wires.
The bonding of neutral to the generator frame is not unique to Generac. It's an OSHA requirement for standby portable generators. Some manufactures do have neutral switching at the generator. Maybe something for Generac to consider for future changes.
This is just something that I think Generac could have covered a little bit more to aid consumers contemplating using this as a portable house backup generator.
If I were to change anything, "out of the box", I would source a better fuel petcock and route the fuel hose a little differently to remove the slight loop seal it currently has created. And of course, I would change the mobil wheel design.
Overall, I think it's a fine product.

I have owned this generator approximately five years, it only has 60 hrs on it. It has been in auth shop twice and has had four new fuel pumps. Also new voltage regulator
It has now blown the fuse behind the control panel and blows another as soon as installed??
I seldom post negative comments on products. In fact this is my first!!!!

Can it be repaired?
I have had my 15KW Generac since 2005. I start it every 6 months and run for about an hour. I put a load on it, portable heaters, fans about every 6 months. Ran it for hurricane Irma and it shut down after about 5 hours of use. Been in Generac authorized repair shop for about 3 months now and cannot see what is wrong. Battery, starter, solenoid are all ok. Guessing in electrical but cannot find issue. Generac rep was supposed to come by shop but never showed. Liked the unit when it ran but.....

I love this generator run the whole house no problem with just a little common sense just remember you can’t have a central air, take a shower with a well pump and electric hot water heater and cook at the same time.

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.

This is my first generator, but we moved to a rural area where the power goes out regularly so we needed an backup generator. I was thrilled to be able to find a portable generator this size, because we can't afford a standby generator.
I was so impressed with this generator when it arrived. It was so easy to set up and came with an extra air filter, oil filter, and so on. Very nice tough.
I feel much better know we'll have heat and water if we lose power this winter!
