A very well-built machine

The last hurricane that grazed central South Carolina sent everyone running to the generator stores. We live in the country with a well, horses and an aging mother living in the guest house. I bought an off-brand 7000w unit then the same day bought the Generac. I could see the engineering quality as I was readying it for its first start. We lost power, hooked up the Generac and forgot about the storm. Very, Very loud machine but it performed flawlessly. Never took the other off-brand unit out of its box so I returned it. We're buying a second Generac 8000e for our small business.

Perfect for backup power

A third storm power loss this year and my old generator simply gave up. I am very pleased with the purchase of the Generac. It has the power to run several circuits that my house is wired to be run by a backup generator. It powers my well pump, refrig, freezer, hot water tank, and several light circuits. Its economical to run and easy to start with the battery back pack. My only con, is the oil fill is a little tight to fit a quart bottle.

Like product and had good reviews

I just assembled the generator today less than an hour. Added the oil provided poured in about a half gallon of gas for a test start. Fired right up. Tested the outlets everything seems to be working fine. Replacing an older smaller unit 20 plus years old. I like the electric start and the operator friendly controls. Not wishing for another power outage but I think I'm prepared. This unit is a little wattage than my old unit and should do all that I need.

Very pleased!

This is a powerful unit that will meet our needs during an outage. For us, it will power the heat strips on the furnace, our water pump, the refrigerator, microwave and enough lights to see our way through. We are very happy with our purchase and as we always say...we hope we never have to use it!

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.

Great Product

This generator fit our needs perfectly. We have a small farm and needed a sizeable unit to power things when power is out with affordability. This unit is large but easy for my wife to move around. It is very easy to operate and quality is excellent.

Great buy

bought after hurricane went home put together, oil/gas in it started right up, after i found a 30amp cord i hooked up camper on 30amp and the house ref and freezer on 20amp everthing works great ran for 12/14 hrs. It would be great if 30and 20 amp adapter were supplied and not having to try and find in an emergency.

Nice Generator

This is a great generator as long as you keep the battery fully charged. 1. Keep the generator battery charged. It will not pull start with a dead battery. Use the battery charged that comes with the generator. 2. If you can't keep the generator on the charger install a battery disconnect between the battery cable and the battery. My battery would drain when sitting for 2 weeks or more. The switch solves the problem. I really like the generator..

Ease of setup and operation

After delivery, the Generac 7000 was easy to prepare for operation, easy to start ( electric start). Our house has transfer switches ( 6) and with our electrician we tested the system and the 7000 to make sure all was running in order. Everything was perfect the first time. I recommend having an electrician go over everything, especially with the built-in transfer switches. The peace of mind living here in Maine, that we can have heat, refrigeration, lights and some comforts is reassuring, especially if the power goes out. This will probably lead to the purchase and installation of a stand-by unit down the road. Thanks for building a safe, easy-to-operate, sensible power source in case of outages which can happen especially here in Maine. I like my comfort and this is real, real PEACE OF MIND.

I'm ready for the winter season

[This review was collected as part of a promotion.] This is my first generator. The delivery was fast and efficient. They even have a number you can call to find out your two hour window. It came packaged nicely in a box but it is very heavy. I love all of the features! It's portable, comes with the plug in battery charger, foldable handle and push button start. I'm so happy I can finally feel at ease this winter season as we lose power frequently! I would definitely recommend this product to anyone looking for a generator!
