Excellent performance immediately after first start. Just what we need for sump pump power. Although assembly is not difficult, the manual for assembly could be improved: The parts could be better identified, and the pictures are too small to be of any help.

[This review was collected as part of a promotion.] This is a very highly performing generatior.and started right away,it ran the water pump.refrigerator,lights and wifi.it rans so smooth without any hesitation.it was very easy to assemble and easy to maneuver and push.it was simple and fast to assemble.The name Generac says it all.and I am very confident that this will serve us well.

Just finished a 10 state tour delivering HighMont Beef to the western states and the Generac XD-5000-E ran perfectly. We had it in a ventilated stock trailer and fuel consumption was minimal and performance was excellent. I do agree that noise level requires ear protection or a muffler but otherwise this generator did what I hoped it would. It ran four large freezers without fail. Thank you Generac!

This generator is worth it's weight in gold. I live in New Jersey and I was hit hard by hurricane sandy. I was without power for ten days. I bought this generator and it powered my whole house and my neighbors house during the black out. I would highly recommend this product. The set up was easy and also the operation of this product. It also has a nice big gas tank for less fill ups and last up to 12 hours on one tank. All my neighbors want one.

I bought this to power a off grid cabin in conjunction with a power inverter... it powers all my lights , TV, side by side fridge and a out house with lights and 1500 watt heater.. I'm in Alaska... my only COMPLAINT is the choke... it simply will not start , warm , cold or hot...without choking it!.. I run it for hrs at a time...turn it off and whether I restart IMMEDIATELY, IN A HOUR OR THE NEXT DAY... gatta choke it... makes NO SENSE...slightly loud... fuel consumption is decent...good machine... would have bought something else, but.. in Alaska variety is limited..shipping is costly so had to buy local...would really like wireless start... not available on generac

We have been thinking of a whole house backup but waited a little long, Irma hit. I ended up picking up a generator as I traveled back to FL as all the ones in town were gone. I was looking for a large enough one to run our well and refrigerators as long as needed to get power back. I arrived back to the house the day after the storm there was no power. So I opened the box and added the oil provided in the box, added gas and connected the battery, also provided in the box, turned on the fuel and slid the chock lever and hit the start button. the generator fired right up and we had power again. It was a good experience and easy to set up. We have had no problem so far.

I wanted to add a generator after how cold this winter has and fearing not having heat for my two small children. However, I have had to use it already twice this summer, and it has started up each time. I have even had some neighbors come over during the storms so they could make their kids comfortable as well.

I purchased about a month ago. Generator arrived in good condition, and unpacking and getting ready to use was well instructed, but a bit more time consuming than I had thought it would be. Only "semi-complaint" is the unit is very loud. It would get a five star from me if the muffler system made the unit a bit more quiet.

I received this item early last spring. I got it to be used in case of an extended power outage which is very rare for my service area. But since I have a grinder pump for my septic, I could have water from the local tower but wouldn't be able to flush without electricity. The unit was packaged and shipped very well. I finally unpacked and assembled it in late July. The assembly was very easy and the unit started on the second pull. I ran it for about a half hour but have not had to use it since. I did install an outside receptacle that I have wired into my main panel. So I'm ready. It is hard to give a review of something that you haven't had to use, but based on my observations as a mechanical design engineer, and from the Generac reputation, I have much confidence. When and if I actually use this generator, I update this review.

I was concerned that the GP15000E would be hard to move due to it's weight. However, what I found was that it is balanced and is easily moved to wherever I need it. I'm not mechanically savvy by any means but this generator is so easy to operate that even I was able to understand and run it right away. I'm glad I purchased from Generac
