Great power without breaking the bank

I had researched several brands and models of generators and this 7500W model topped the list each time. Bought it to run tools for home renovation jobs and backup if power was ever lost at home. Does everything I need it to do! Great power for the price! Only downside is noise. This is supposedly noisier than most in its class. This is not an issue for me, but if it was regularly used go home backup, I'd consider a quieter one for running throughout the night.

No power :(

Well, I bought this a couple years ago to use when we go camping. I used it once and had no issues. Today I got it out to power my furnace in the house. None of the outlets have power. I checked the breakers and no luck. I tried the GFCI, but it won’t trip because of no power.

Love the first 8000 but the second generator let me down.

170 hours on generator -two months old Stopped producing power. Not happy. Power would come back when I jumped the field with a drill - spinning it backwards. Brought to a dealer rep - we will see what they find. Hoping it will be under warranty without a battle. Walpole,MA

Best value

Best value for price. Easy assembly. Started right up. Ran my pool pump, kegerator, deep well cooler, 1 window ac unit, 1 in wall ac unit with ease. It didn't even strain. Refrigerator and house lights are on solar, battery backup system. I did not try running central ac, stove, although it probably would if other loads were shut off. Connected my oscilloscope while under load. Voltage and frequency right on. Very clean pattern. More than happy with power output, quality.

At least the rope start is easy, the battery didn't last 3 months.

The GP8000E is a very capable machine. It can run our whole house and never falter. The electric start was a requirement so my wife could crank it up. There is the first weak spot. The machine is just 4 months old and has 3.2 hours on it and the start battery has cracked and is leaking. Yes, I recommend the unit, but I recommend that you plan to replace the starting battery very early. The 20amp cord that comes with some is of marginal utility, I suggest that you look a 14-30 cord if you chose to do much at all.

This is the one!

I bought this unit because I am building a house in the country. Com Ed won't have power there for another month. It took all of 10 minutes to put this together. total 15 minutes from box to running. Loaded it on the 1st start, Wow, this will run everything I need it to. Then after the house is built, it will serve as a back up in power outages. Illinois doesn't have the best of winters out here in the country. I recomend this to any one serious about a quality generator!

Great Portable Generator

A portable yet powerful generator that is well suited for home backup power needs. Wheels and collapsable handle make it easy to manuver. Electric start makes it a snap to fire up. Enough output to protect freezers and fridgerators. 240VAC has enough output to power a well pump.

Money well spent

I bought this generator just in case,let me tell you it pay for itself after we got hit with Hurricaine Sandy,we lost power for about 5 minutes that took to connect it to the transfer switch,very well and performed superb,plenty of watts to keep with the normal life even after the power is out...Love it!

Great unit!

We have had the 17500 for a few years now and it has been great for us. We live near a national forest so when power goes out it generally stays out for several hours to several days. We do the regular maintenance on her and have a trickle charge solar panel on the battery. It definitely burns through fuel, however, it runs EVERYTHING. Also is very heavy, so have so.e strong people around if you need to move it or place it strategically and then buy a sturdy after market cover to keep it out of the elements.

Works just like is it supposed to.

Bought this almost a year ago, worked well, although I only had to use it the one time then. Power company trimmed all the trees over the lines last week, so I don't know if I will ever need it again. Glad to have the b/u though. I know it will work next time because it is a Generac
