Brand New Product with Start Up Problem
By from Peoria, IL, USA on Jan 16, 2016
I have had to return my XT 8000 Generac to Lowe''s for repair. It is brand new with a start up problem that the kill switch is bad. The only way to turn the product off is to turn the gas off and run the carburetor out of gas.

Dirty Power
By from Oklahoma, USA on Dec 30, 2015
Purchased this 6 months ago and had an opportunity to use it due to a major power outage (late Dec 2015). Initially I plugged up my forced air gas heater, and it worked for maybe an hour and caused my unit to go in to fault mode. Needless to say we got a little cold during the 20 hours the power was out (thank god for a gas fireplace). Once the power was restored I had to call an HVAC guy out to repair the heater. It did power my a few lights, my MS Surface and the internet modem with no problem. After running for an hour, my power bar stopped working, haven''t had time to test it as this just happened. Buyers need to be aware that generator has an above acceptable harmonic noise level and power output does fluctuate, both of these issues will damage sensitively computer controlled appliances. I''m glad I didn''t plug up my 65 inch led TV or my Samsung refrigerator. Also be aware the battery charger that ships with the item is not Ideal, do yourself a favor and install a battery tender junior. Because of my experience, I''m actively looking for a whole house generator with smart power technology and a harmonic noise level below 5%.

Very Good Buy!
By from WA on Nov 25, 2015
Bought this unit when power went out due to a major windstorm. Everything needed to get up & running was in the box ( even oil ) except gas and common hand tools. Set up was about one hour with one person. Lesson learned: dismount the battery to hook it up. The connection hardware is small, and the space tight if you don''t. It started right up and ran smoothly for six days. Carried all of the load except hardwired ones with comfortable margin. Am going to have a transfer switch installed for that. The only drawback so far is that this unit is LOUD! Don''t think that muffler does anything at all. All in all, great capacity/value!

Help your local power company
By from Virginia beach on Aug 17, 2015
Bought this on advice from a friend to handle power outages from hurricanes and snowmagedons. This generator can run all your essentials, a fridge, freezer, portable ac unit, some lights. We make one room comfy and can run a small microwave when needed or toaster. It''s easy to set up, use and maintain. The price makes it worth it, if you go bigger than this go for a built in unit.

System would not provide adequate power to UPS sys

System, works, turns on easily with battery but was only outputting 97VAC when anything was plugged into it. Does not work properly, poor performance.

Very happy so far!
By from NJ on Aug 04, 2015
First, let me say how impressed I am to see Generac submitting responses to these reviews. That leaves a great first impression for Generac''s customer service. After the last power outage lasting nearly a full week, I decided that I needed a generator to keep the fridge, freezer, sump pumps and well pump operational. I did some research and decided that the XT8000 would be sufficient for my needs. It''s affordability was definitely a key factor as well. Even though this is a Lowe''s exclusive, which I don''t understand the purpose of, I trusted that Generac would not release anything that would tarnish their reputation for building quality products. I did call Generac, who assured me that parts and service are readily available. Assembly is easy if you have basic skills. As other reviews have stated, the battery connection was very tedious. And the pin to hold up the support handles on my unit would also not fit in the hole properly - but that could be fixed with a drill if needed. The back panel had a bit of a dent in it from shipping or shifting in the store, but not worth returning or complaining about. After properly filling with oil and just enough gas to test it, the unit started up with ease. It blew out a tremendous amount of smoke for the first couple of minutes. I just figured that was from oil on the internal components from assembly. The smoke cleared up, and it runs clean all the time now. Exhaust noise is practically eliminated thanks to a massive muffler system. Most of the noise is from the clatter of the engine and generator itself, and not unexpected. So yes, it''s loud, but so are all the other big generators out there. I wired up a generator inlet and a safety interlock device to properly and safely back-feed my panel. I ran my well pump and our oil fired hot water heater, along with quite a few other items for my test. I didn''t even hear the unit cycle for extra power. I haven''t used it longer than a few minutes for testing, but I''m confident that it will get us through when we need it. One thing that''s odd is the auto idle control feature. If the generator has any draw at all - and I mean any, it shoots up to full throttle. So don''t think it will idle down if you''re not drawing much. It will only idle down if you''re not drawing ANYTHING - which is rarely the case. Overall, I''m extremely happy with this purchase. Of course, time will tell the story of quality. And, now that I''ve installed a proper portable back up generator system, we will likely never need it. You''re welcome, neighbors.
