My XG10000E has had a long term test, it passed
Would RecommendI live in the Upcountry of South Carolina, where we just had a pretty severe ice/sleet/snow storm. We received about three inches here at the house. Our power went off just after midnight, 28 hours ago, so I immediately started the generator and it, as usual, fired right up. I'd like to know that the power company will have us back on the grid today, but with 70,000+ without power, we don't know yet. I refilled the 10 gallon tank a second time tonight, first five gallons at about 6PM, seco...

Extremely Reliable
Would RecommendAfter Hurricane Irma caught me off guard in 2017, I swore it would never happen again. I bought the 10000E. I set it up per instructions. Fired it up. Put it up in November last year. Haven't touched it until last Wednesday the evening that Hurricane Michael hit SW GA. Our power went out at 5 pm on the 10th. I turned it on. Powered my well, hot water heater and all my house. It is still running right now on the 17th. It has well over 100 hours on it and has worked flawlessly. Thank you Gene...

Not as good as my old Generac
Would Not RecommendMy old Generac lasted for almost 2 decades and was easy to service. I just received this one today, put the wheels on, added oil, etc. First problem, there was no nut/bolt to connect the negative wires to the battery terminal. Either it wasn't included or it came off in transport--my guess is it wasn't included. I used a temporary solution to connect it and crank it. It cranked easily, but second problem, it didn't have any electrical output. I turned it off and when it was turning off, th...

Heavy!
Would RecommendThe XG10000E is very well built and the quality can be felt in how heavy the machine is. The generator has good tires but is difficult to roll over grassy areas. I was disappointed to learn that the hand grips on the handles are NOT glued on! This could be dangerous if someone is pulling backwards when the grips come off. The controls are well laid out. The manual does NOT tell the owner how much engine oil that the crankcase holds...only to fill the crankcase to the full area on the dipstick. W...

Really let down
Would Not RecommendI purchased this very expensive generator based on the well known brand name and the fact that it is American made. I used the generator 1 time...... yes 1 time. It started and I then stored it based on all the manufactures directives. I took it out and charged the battery and it wouldn’t start. It wouldn’t even turn over. A mechanic friend told me it was the starter that’s bad. I could not believe it on a machine that reads 0.0 on the usuage meter. I now have to submit it to a local shop that h...

Worst genset I ever had
Would Not RecommendI have XG1000E unit bought in 2012. Here is my experience with this unit - overpriced low grade components, junk. 1. It came with loose bolt inside alternator. If I wouldn't spot it and removed it with pincet it would have damaged the alternator or caused personal injury. 2. The carburetor is of very low quality, namely the the magnetic pin which opens the fuel line was rusted and not moving upon start. 3. The plastic shutoff valve leaks fuel in cold temperatures and if you have this situat...

This portable is exactly what I needed for Home backup
Would RecommendI live out in a forest, with several fairly short power outages each winter, and sometimes in the summer. I needed an easy to operate portable generator around 10kw for powering up my home, including freezers and our well pump at 220 volts. This unit is compact, reliable, with a number of helpful features that make it easy for me and my family to operate. I was impressed with the reviews for this Generac generator and am happy with the purchase. Time will tell if it lasts the test of time.

Excellent piece of equipment
Would RecommendAfter being let down by our Coleman during Hurricane Irma, we decided to go with Generac. We are beyond satisfied with this generator. Very solidly built and easy to use.

Just what I needed
Would RecommendJust received my new generator about two weeks ago. perfect timing, I just completed wiring of my transfer switch. I tested last Saturday the 7th. wow I was able to power my 5 ton A/C unit, hot water heater all my lights, fans, computer, and TV. with just over 5000 watts, with plenty of power to spare. Very Happy with the performance. The only drawback which isn't really a game changer is the placement of the oil inlet tube, a little difficult to fill, over came problem by cutting a clear pla...

Awesome so far, but...
Would RecommendPurchased from Lowes online and picked up about 2 weeks ago (March 2018). Was excited about getting our generator and being prepared for hurricane season (we live in Florida). Unit comes on a small pallet with the box basically just slid down over it. Found this a little weird but allowed me to inspect it before I took possession and all seemed well. Brought home on my trailer and was able to install the wheel kit myself so that I could wheel it off the trailer and not need help to off load...

All you need
Would RecommendJust received my generator, this is a great generator, had a little bit of trouble starting it for the first time, but might have been fault, may have over choked it. Once started it was great, was able to run over 90 percent of my home. Including my 5 ton A/C, TV, internet, all my lights, ceiling fans, refrigerator. All under 5KW. The only draw back was the placement of the oil fill tube, but easily fix by oil tube with a long narrow funnel, also for long term storage you need to remove the...

NEVER buy Generac
Would Not RecommendFor years, I swore i would not buy another Generac, and each time a Generac failed, I was talked into a bigger, 'BETTER', more expensive model. Regardless, its not the generator - almost every generator generates power out of the box - its WHEN your Generac fails the real adventure starts. 1) Generac has NO warranty support - they ask you what happened when it failed, and then they pick out one tidbit out of the conversation that is the basis for them voiding the warranty - happened THREE time...
Problem from the start/no support from the company
Would Not RecommendOrdered from Lowes on Nov 3rd. Arrived 3 weeks later. Set up was fairly simple with the exception of adding the oil. You can see where the dipstick is in the main picture. That's where the oil is added. It is very awkward to add because it sits too close to the rear of the panel. I Filled with 5 gallons of gas, started it, and let it run for 20 minutes with nothing plugged into it. I shut it down and when I went to roll it back in the garage, I noticed a puddle of oil and a bolt on the ...
Good looking unit
Would RecommendOverall quality is good. Powerful engine solid built. I looked at a lot of different brands. This was the best.

This product has great features.
Would RecommendAlthough I thought this product was a bit pricey, I bought it for the reliability. It has more power than any other to run my home when the electricity goes out. My home is all electric so having a generator is by far a great investment. I would highly recommend this product. It's easy enough to start that my wife can do it - electric start (battery powered).

Very good generator
Would RecommendI purchased this generator to be used as a back up unit for my home. I was looking to purchase a whole house unit but decided on the XG10000 because is portable. I can take it to where it is needed (family members homes) if my power is on. When not in use I keep it under my work bench in the garage. I do need help getting it into my truck she is a bit heavy. The electric start is great. It will run everything I need to run in my home and more, I can toss a couple of extension cords to my neighbo...

excellent generator!!!!
Would RecommendThis is the best investment I have ever made! I purchased it as a special order from LOWE'S and the salesperson was extremely helpful and knowelegable. I purchased the extended warrenty with it,However I doubt that I'll ever need it.The unit starts up and runs great every time!! I'm a very satisified life-long customer for LOWE'S.
Works like a charm
Would RecommendWe moved to the 'country' north of Spokane, WA earlier this year and were warned of potential power outages due to weather. I researched portable generators with the goal of buying a high quality unit that could do more than power a toaster and decided on Generac's 10Kw model. We had an electrician wire the house for it early in November, and on the 17th, the area experienced a record windstorm with gusts exceeding 70 MPH. Over 200,000 homes, including ours, lost power for up to 9 days. Our Gene...
