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.
