Can’t depend on OGE anymore….

OGE is having major issues of late on our grid. Past Sunday the weather got to -4 …. windchill -15. My electric went off for over 5 hrs and I ended up replacing the pipes in the well house due to everything freezing up. I researched and decided to purchase this Generac 7500. Very glad I did. We’ve another major storm brewing this upcoming weekend and I wanted to be ready. I can’t depend on OGE anymore and having an alternative power back up gives me the feeling of control and power over my situation. Instead of being a victim of OGE.

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.

Mighty Powerful Standby

First of all Generac is the best. I have purchased many industrial generators for hospital backup. I know that Generac is quality. This unit meets all my needs for home backup without having to go to s standby unit. It was easy to assemble and started right off the bat. Much quieter than expected for its size. This unit is well built and I am sure will last me a lifetime. Fuel tank capacity and placement are optimal and I really like the built in strainer. I am very please with this purchase.

Excellent

I bought the GP8000E about 6 months ago for my house, I liked Generac so much that I just bought a GP2200i 9/12/2018 and received it today 9/15/2018. I just put oil in it, and going to get some gasoline. This one is for my tools (drills, circular saws etc.) I like Generac products. Thanks, Frank The GP8000E is Excellent The GP2200i I haven't tried yet.

Great product

I have had the pleasure of not having to use my generator that I purchased just over a year ago. However for the first time this summer it was finally used but yet again not by me. During a series of severe weather outbreak a friend of mine last power due to downed trees. I offer my generator to him to help keep his basement from flooding. His intention were just to use it for the sump pump. He ended up running not only the pump, but his freezers, refrigerator, air conditioning units and other things. He used it for 40 hours straight and forgot he was even on a generator until he had to fill it after the first 27 hours of run time.

Best " bang for the buck"

After researching and using other products, such as Honda. I could not help but know that my GP6500 is the best bang for the buck! I know the dependability of generac having owned one in the past ( used it as an enticement on sale of my previous home). This particular model will also give a surge of power when increase of load is needed . With proper maintenance there is no reason it should not last a very long time. Very comforting to know the dependability of the generac name. Living in Florida having dependable back up power is essential. Sleeping better knowing I now have it!

A BEAST for hurricane season!

[This review was collected as part of a promotion.] We live in Central Florida, and unfortunately having a generator has become a necessity for the months of August-October. We’ve spent too many days post-storm without power, losing both groceries and our minds (from heat). With the hurricanes seemingly getting worse each year, we finally decided it’s time to invest. We jumped on a Generac due to the reliable name brand and reputable quality. Needless to say, the recommendations received from family were good ones because we’re seriously impressed with this thing, so much so that our neighbor saw it delivered and came over to also rave about the Generac brand. One of my favorite features is that this generator can take propane, gasoline, or natural gas. It’s pretty strong and can power appliances, fans, cell phones (imperative), internet, and other small conveniences to keep children occupied. We also plan to invest in a window AC so that we can still have a bit of cold air in at least one room! Just having all of the necessities accessible makes a scary situation just a tad bit more tolerable. As with most generators, this one is HEAVY so be prepared with a plan for moving it prior to getting the wheels on (delivery slip said 275lbs!) We needed three adults to lift and move it, but the wheels definitely help once installed. All parts are heavy-duty, yet easy to operate, but just be aware that this is quite big and quite heavy. That’s understandable with such a powerful unit. If you’re in a hurricane prone area like me, this is one of those purchases that you hope you never need, but will be pleased when you do need it! It’ll definitely make the post-storm recovery just a little bit easier.

Everything you will need

I bought this in the fall of 2012 after Katrina ripped through the Northeast. Our area was ten days without power being restored. We suffered through three days without power before getting this. Our home water supply comes from a well. No power, no water. Or heat, or showers, or communications. This unit has enough power to run the well, satellite, refrigerators, freezers, lights, coffee pot, microwave, televisions, and the list goes on. I just pulled it outside and started it up again for the second time this year. It powered up on the second pull and was running strong. I never worry about losing power now. Get the biggest one you can afford, but the 6500 will get you through any power outage with minimal disruption to your life. No regrets on this purchase. Quality machine.

Very simple to start and use.

No brainer start and stop generator. I researched generators to buy and always settled on the Generac. Then I stopped by my neighbor/electricians house to see his setup and he had the exact model Generac I had planned on purchasing. He endorsed his model and installed mine and I couldn't be happier.

Do your research and then buy this one.

I had purchased a Westinghouse Generator and it had all kinds of issues. Before I took it back I did finely get it to run. I don't know who makes there motor but it just sounded very cheep, loose and claney took it back Fast forward I decided after researching several other top notch units I decided on this Generac GP8000e. I was missing things not in the main box but the place I bought it from supplied it all so all was good. I connected the battery, it was charged up, added the oil added mid grade gas, turned on the gas flow to the carb and it started right up and this motor is tight and sounds like a top notch motor. My only regret would be the tool kit that Ace gave me was the cheapest 2 wrench's I think I have ever seen in my life and I don't think they are relevant to anything. i was also missing oil and they gave me Pennzoil and not Generac oil and I heard Generac is the best. Buy it you you wont be disappointed!!!
