Easy to assemble and starts right up.

Got the generator the eve of the 2015 blizzard. Setup was a snap and starting was even easier. This was a replacement for a older generator I had and between the two units genarac wins hands down, would recommend it to anyone even if your not handy with mechanical things. my grandma could put this together.

Having Issues

I am in the middle of Hurricane Ida. I decided to spend the money to get another generator as my Briggs and Stratton was getting more difficult to run. I purchased the generator and it ran fine for 10 hours. It ran out of gas and I filled it up with gas and it would not crank. I pulled the spark plug and cleaned it and it would not fire. I went to the store to ask about possible issues. I was told to put more oil in it. I already put the quart supplied and I was told to fill it up. I returned home and filled it up with oil. I even replace the spark plug and still no fire. I loaded up the unit and got another one. Got home, it ran for 1 hour and stopped. I went outside and cranked it again. It ran for 5 minutes and stopped. I removed all but one extension cord and removed the air breather and it is now running but i dont have much confidence in it. I drove 45 minutes 3 times to get it to work. It is very hot and I am trying to stay positive but its getting more difficult. I called Generac 3 times and the customer service reps were nice but none could tell me why I was having these issues. Its not easy to return as the unit is heavy and I have to stuff it in a car. I also am trying to work during this time as well as get all the damages to my home repaired. I thought Generac would be a good brand and perhaps I just got two bad apples in a row. I did not overload the unit and used strong extension cords. I dont have time to return it again as I have other things to do as a result of the hurricane.

Excellent Product. Just what we expected.

We ordered this after Hurricane Matthew and being without power for 5 days. We went with the larger model based on price and recommendations. We are happy and quite pleased with our purchase. We highly recommend Generac! We are comfortable and assurance knowing we will now be better prepared.

High quality

[This review was collected as part of a promotion.] I am extremely pleased with this Generac generator. My husband and I had no problems whatsoever setting this up. It's actually not as loud as I suspected it would be, maybe about the same noise as a lawnmower. We were able to hook quite a bit with this (refrigerator, few lights, microwave,etc.) This will definitely come in handy this winter as we're in Western New York and get some pretty harsh weather and are constantly having the power out for long periods of time. Definitely a good investment and this generator is high quality and highly recommended!

Improper Voltage and Frequency

First run under load. 260 volts and 62.4 hertz I would like the instructions to adjust this. No service in my area. I would have to drive 80 miles to a shop that may be able to adjust this. The current fuel prices don't allow me too make two 160 mile trips . They will not take it back because I have run it. Running it, is the only way I found out it was not outputting proper voltage and frequency. Does anybody know where to adjust the xd5000E voltage This obviously was never checked at the factory before it was sent out. I am capable to do this.

Great Generator To Have After The Storm

We recently purchased the Generac GP6500 and couldn't be more pleased with this product. This generator had its fair share of use after the recent damage caused by hurricane Florence in the coastal region of Eastern North Carolina. The GP6500 generator was easy to assemble and started up on the first pull out of the box. The generator ran continually throughout the daytime hours for a solid week after the hurricane had passed through our area knocking out power to our subdivision. We had NO issues or complications with our Generac GP6500 while we were waiting to have our power restored. Also, we noticed that the full burn of the generator seemed to be more efficient than expected. This was a major relief to us since all gas stations in our area were closed due to lack of available refueling trucks as well as there was no electricity to operate the gas pumps at the stations. Not having to worry about running out of gas for our generator was very reassuring. Not only did we use our Generac GP6500 after we lost power at our home we also continued to use it as we participated in various clean-up projects for others homes who suffered severe storm damage in which utility power was not able to be restored. The GP6500 was small enough to be transported to various worksites as home repairs were needed throughout our region. Again, we used our generator all throughout the day while we operated electrical equipment to assist with clean up and various home salvaging activities. We've since winterized our Generac GP6500 (which was simple and easy to perform) and have it stored and ready for the next time it is needed. Unfortunately, living close to the coast in North Carolina results in yearly threats of hurricanes. However, we are comforted knowing that we are prepared for any future storms and power outages with our Generac GP6500 ready to go in the garage. Good Job Generac!

Lots of power

Bought the 6500 in 2015 after losing power for 5 days after a storm. I went with Generac because of the trusted name and reviews. Recently lost power in a winter storm for two days. This baby ran for 48 hours straight through a transfer switch and powered my heat, two refrigerators, three tv's, all my lights no problem! Best $800.00 i ever spent.

Awesome generator

Bought this for backup when the power is out. Electrician installed an interlock switch so as not to backfeed power to the grid. Now i have what i need when the power is out !! Love the electric start. Also like that the choke is integrated into the start switch. Mine was a display model and was missing the cord for charging the battery. Called customer service and they promptly sent one via mail at no charge. I have owned other brands and generac is by far the best.

Reliable with a large tank

We lost power at home and had to buy one of these in an emergency for our fridge and freezer. It seems to work well. The only issue is that it says that it should not be left in the rain, but yet it has a CO sensor. We had to figure out a good ventilation situation in the garage to make it work, but it would be great if they could be left outside in rain storms. Oh well... Next design?

This Generator Saved My Butt

I bought this generator a few years ago and boy did it save my butt. I lost power last winter and had to use my new generator. Having it I was able to Heat my house and keep my refrigerator cold. I also had some lights wired too. Having this generator made my wife happy and that is what's important. A happy wife is a happy life. This was money well spent. Thank You General.
