Great performance, easy to use

Bought GP15000E after extensive research. Because of demand, it took almost four weeks to receive it and Generac transfer switch. Worth the wait. Both were reasonably easy to set up. I store the generator inside garage, but suggestions for shelter when it is being used outside would be appreciated. There are some slight differences in operating instructions between the generator and transfer switch manuals.

Good value for the money.

I got a great price on the GP7500 (no electric start) so decided not to suffer through a power outage at the cottage again. It went together easily and my 13 year old started it with the first pull or two. haven't needed it yet, but I'm confident it will do the job well. One drawback is that I had expected it to run quieter.

Yes....purchase this one

We bought our first Generac 7000kw in 2004 it has ran our 55' trailer in the middle of the bush for 7yrs. then built our OFF GRID home powering all our power tools needed for the build, then for the last 3 yrs used as a back up to our Off grid solar system. Still going strong only serviced once to clean it up with a tune up. Purchased New one GP7500E to carry us forward for another 10 yrs and use the older one as our back up. Quiet, easy to use, I will always buy a Generac.

Product did it's job right out of the box.

Took unit right out of the box, added gas and oil and one pull, started right up. Had plenty of power to power up what I needed. Ran it for six hours straight. Saved my contents in fridge, freezer and keep my sump pump running. Wife asked if it could run the coffee maker. Yep it did. Well worth the purchase price!

Reliable, easy to operate, and so versatile!

[This review was collected as part of a promotion.] We own a cabin in North Carolina that was affected by hurricane Helene. Our power has gone out multiple times since and the Generac GP9500E Tri Fuel Generator is my new go-to source of confidence. What I appreciate most about this generator is its versatility. It can run on gas, propane, or natural gas, providing great flexibility when fuel options are limited. The maintenance process is straightforward, thanks to clear instructions, and LOVE the electric start. It makes it a breeze to operate. The COsense® safety feature adds an extra layer of peace of mind, knowing that it’s equipped with advanced carbon monoxide detection. And with its 7.5-gallon fuel tank, this generator can provide over 10 hours of runtime at a moderate load. In conclusion, the Generac GP9500E Tri Fuel Generator is a wise investment for any household. With its impressive 12,500 starting watts and 9,500 running watts (when fueled by gas), it’s more than powerful enough to keep our home running smoothly during an outage. Considering its size, the noise level is surprisingly reasonable and doesn’t disrupt our daily lives. I’m incredibly grateful for this reliable and versatile generator.

Excellent Generator

Generac makes a quality product at an affordable price; plus I prefer to support American made products. I bought this model on sale for $800. In the past 15 months, I've only put 75 hours on this unit to date (although it ran for 72 hours recently with several cooling/fueling/oil check breaks - at 40 hours, I hadn't burned a drop of oil but I did the first oil change). Basic maintenance is simple enough for anybody to perform. The GP8000E feeds my main panel and powers everything I demand in my house, such as my pellet stove, electric range, well pump, lights, microwave, outlets and TV. I haven't tried powering my hot water heater but at 5,500 watts, I think it would do just fine if I shut some stuff off. It sits approximately 20 feet from my bedroom; the noise is barely noticeable when I am laying in bed. I do ensure that my carbon monoxide detectors are on whenever I have this unit powering my house. It's much more fuel efficient than I expected, averaging around 2 hours per gallon of fuel. With all of this being said, I do hear a bit of occasional surging once the temperature hits 25 degrees or below but it has no performance issues. In my opinion, portable gas powered generators are the way to go for powering a house during an emergency. Natural gas isn't an option in my area so we are limited to propane; getting a propane delivery after being without power for a week isn't always an option!

xt8500 efi is a very nice generator for the price

I'm a controls engineer who was very fussy about what kind of power that is going to my house. i know what kind of damage could happen if you get power spikes, power surge and transient voltage. all kind of the same thing. when testing what kind of power that came off of it seemed great. 60hz and 240volt RMS. I had zero problem with it. i do charge the battery every 90 days give or take. my only complaint that i have with it is i wanted a spine on oil filter. Generac said it had one, it's a fine screen not quit what i wanted. but it was already delivered so i keep it. One thing i would get for your house with any generator is a whole house surge protector.

hard to move

I give this 17500E a 5 star rating. The only con I have is the portability. I have to move the gen. around. I mounted a heavy duty caster with brake the second day I owned it , this totally changed the portability, I can move it around with one hand. Also I believe the handle needs to be adjustable so you don't have to do a shoulder lift to get it rolling.

Easy to maneuver

[This review was collected as part of a promotion.] Works great. Took it on our latest camping trip it ran our site and our neighbors site with power to boot. Quieter than I expected! I liked the idea of never flat wheels but they seemed a little bent. Handy fold up handle that was well balanced and easy to maneuver was a bonus.
