Excellent value for the money

This new unit is replacing a 9 KW portable unit that ran my whole house except for the Hot Tub and central AC. The new Generac runs the whole house with power left over. I just wish that it would come with a voltmeter. It was easy to assemble and runs great.

Awesome features

[This review was collected as part of a promotion.] This 3600 Generator is really great. First I love that it comes on wheels so that when the husband is not home I can maneuver it by myself.. I like that it I gas powered only so when we have rough Oklahoma weather and the electric goes off I still have a way to have some power. Make sure you read the instructions for set up before you start your generator. I love how it is easy to use and easy to store! I got mine free from the TRYIT program but you can get yours where Generac is sold.

Good planning will bring a good installation experience

We had three installation quotes and they were all very different configurations. Not many installers know the large portable set up. took longer than anticipated, and research. Once we reviewed the steps it was very easy. Moving to desired location also took planning as this is 450lbs. Good idea to have a battery charger on hand, we needed to charge the battery.

Leaking Gas - Brand New!

Selected the GP7500E above two other choices. Assembly was easy but, I was filling up the gas tank and the gas was leaking out the carb almost as fast as I was pouring it into the tank. Called customer service and found out this is a know problem! Now, instead of taking it to our cabin this weekend, I am taking it to a Generac Service Center. Very unhappy that it is leaking gas out the carb and it is a know problem! Maybe I will get a gift card for all my problems.......but......I don't think so!

Beware it could be delivered with a defective battery

I purchased a GP8000E and paid extra for the electric start. I started it when it first arrived to ensure all was OK. It started right up. 8 weeks later I went to exercise it and the electric start would not work. I took it to a factory authorized service center where they discovered the battery was defective. It would not charge nor hold a charge. They replaced it and it started immediately and now runs fine. THE PROBLEM....This generator cost over a thousand dollars, is brand new with 12 minutes run time on it, YES 12 MINUTES. The generator was delivered to me with that defective battery and Generac WILL NOT COVER IT UNDER WARRANTY!! I cannot say enough good about ELECTRIC GENERATORS DIRECT which is who I purchased it from as they are a Generac Distributor. They stepped up BIG TIME once they were told what happened and THEY took care of this repair. Fabulous customer understanding and support by ELECTRIC GENERATORS DIRECT. Generac..not so much. This is a major purchase for most. Hope it runs and lasts longer than the factory supplied battery!

Everything you need.

Setup was easy. Starts easily. Plenty of watts for most everything in home. I ordered it during hurricane season but didn’t receive until later. It hasn’t been field tested in the real world. I did have a certified electrician install a whole house manual switch to make things easier. That was very expensive, but will be worth it. It will be easier to operate circuits using my existing breakers. I am sure the generac generator will do its job.

Good value

While I only have a few hours on this generator, I've owned and used a few different models from different manufacturers. This one seem to be built on customer feedback. Simple features like the included fuel filter and the gas cap retention chain made me smile, along with the charging port for the battery and beefiness of the roll cage. Like many generators, it has a plastic choke lever, which I consider bad design. Its not a matter of if it will break, its when. There is plenty of torque on that lever. The included wheels aren't up to the quality of the rest of the product. They look and feel like they belong on a kids toy. I replaced them immediately with a better quality wheel w/ metal hubs and bearings. Otherwise, good product.

Good Value

Bought this machine to use during a power failure. Found a great price on line, with free liftgate shipping. Started up first time right out of the box, so that was encouraging. Startup procedure is simple. Has sufficient capacity to run my well pump, fridge, microwave, lights, TV's and computer. Have only run it to check out the new transfer switch and panel, but it ran smoothly throughout. Kinda noisy, but won't be running it at night anyway. Lacks a power meter and the fuel level gauge is pretty cheesy.

Very Good So Far

I bought the Generac GP6500E because of an extended power outage last Christmas. We recently had a Fall snow storm and were out of power for 4 days. The generator performed very well during the outage. Started on 1st or second pull every time. Provided all the power I needed to run the well, furnace, lights, TV, satellite dish, Fridge and freezer. It would run longer than the 10 hours the specs say at half load. Only issue is that it is a little bulky to move around if you are not on pavement. It is a good sized machine so it sinks in a bit on grass, especially if it is wet. The wheels are good sized and the frame is sturdy but it is heavy enough to make it a little difficult on grass, sand. The wheels also pack up with snow and stop rolling so you need to keep the path clear to the ground or clear the wheels frequently. Other than that it has been a good machine.
