Excellent quality, design and reliability

I don't write many reviews but we are in an ice storm power outage. I dusted off my Generac 6500 XL which I purchased in 1999. It started right up and is running my entire house - well pump, furnace, frig, and lights including Christmas lights. . It is 17 degrees out. This generator is great. It starts first or second pull every time. It will be hard to find a replacement to match this one if it every wears out. Happy generating.

Excellent Generator

The power to my house has been pretty reliable up until this year. We have has three outages for extended periods of time so far this year. I have a well and a freezer full of beef, so I bought this generator to power my house during these outages. The power has not gone out since I bought it, but it does run all my appliances and the well pump without any problems when I tested it. It is worth having the insurance of stand-by power when it is needed.

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.

Easy to set up and use

Bought this as an emergency purchase. Had borrowed a no name generator for camping to have it quit working. Went to Menards in Princeton Indiana at closing time and found this model. Had been wanting of my own for various reasons over the years and have always put it off because of so many choices out there. Being forced to make a split decision in bio this one was a blessing in disguise. Could not be happier with this generator.

Love this generator

I bought this generator 3 years ago and have lost power 4 times, once for 3 days and it has never let us down. The battery died after the second year and I never replaced it as it always starts with one pull. I always treat my fuel with stabil then shut the fuel valve off with the engine running letting it run until it dies, this assures emptying out the carburetor reducing gumming up issues from hanging around. I run Pennzoil 10w30 motor oil and change it anually. What I really like is the engine adjusts for load so it isn't screaming when there is no load.

Lots of Power for a Compact Unit

I bought this unit to replace a larger generator two years ago. It went through on hurricane like a champ. One half of my home was easily powered (which was more than enough, 1 AC 3 yard pumps, misc. 20 A breakers). The unit stores easily when not in use and is easy to move to hook up the transfer switch. I recently had a bad battery and the folks at Generac are replacing it. What a pleasant surprise and a guarantee that I will buy another Generac when the time comes.

Great product for the price.

Unit now showing 25 hrs. Bought after storm took out the electrical service drop. Put together and had up and running in less than an hour. Operation is straight forward and pretty much plug and play so to speak. Only thing I noticed was the powder coating on the frame seemed very thin in places. could have been a little thicker. This is not a game changer just something I noticed. When you add the oil the first time try to have a long neck funnel, it's a whole lot easier to hit the opening to add the oil. Look forward to many years usage from this unit.

Tbis product is expected to meet our needs during a storm caused power outage!

The.instructions for assembly were easy to follow. The instructions were straight forward with all parts included. The generator started on the second pull and worked flawlessly. I feel confident the generator will help keep my family comfortable during an extended power outrage. Having the generator and being able to connect it to the house is very convenient.

Great generator

I love the generator. It works excellent, just as expected. Starts immediately and runs well; provides the power I need when required. The only complaint I have is the noise level when running. Surely Generac could or should have equipped the generator with a muffler system to quieten the sound emitted.
