It will definitely work for you.

I had this delivered to the house. The packaging was very good. No damage. I did all the assembly within a half hour. Filled it with oil and put some gas into the tank. I used the electric start and it started up with no problems. Temp outside was less than 5 F. I bought the electric start only for my wife so she could start it up if I wasn't home. The manual provides all information needed to star and maintain the unit.

Started Right Up & Reliable

I got this one to replace my older model Generac which needs service- 15 years old and still running well. This new one is just as reliable and started up right away the first time I used it. I use it weekly to pump well water and also use it for my house as a back up power source (off-grid). I researched for months before deciding on this generator and it has been everything that I needed and expected. Works great and I highly recommend it!

High quality

[This review was collected as part of a promotion.] I am extremely pleased with this Generac generator. My husband and I had no problems whatsoever setting this up. It’s actually not as loud as I suspected it would be, maybe about the same noise as a lawnmower. We were able to hook quite a bit with this (refrigerator, few lights, microwave,etc.) This will definitely come in handy this winter as we’re in Western New York and get some pretty harsh weather and are constantly having the power out for long periods of time. Definitely a good investment and this generator is high quality and highly recommended!

Great machine - runs everything

I bought this generator to replace a much smaller unit so that I could run the electric range, HVAC, refrigerators/freezer, and water pumps in my home. I installed a 50-amp transfer panel and tested the setup with all the circuits pulling power, and the generator never missed a beat. Future plans are to install a 30-amp transfer panel to power the electric water heater, lights, and outlets. Others have remarked that the unit is too heavy to put the wheel kit on without help. I had no such problem - a hydraulic floor jack would probably help a lot.

Great product

We used this generator less than 50- hours. When we needed it again summer of 2020 we discovered the generator burned!!! Very DISAPPOINTED We had to use an older 10- year old Briggs and Stratton that started up right away. We are currently waiting on new generator to be ordered and delivered , due to Covid reasons it’s taken this long. We pray once a new generator is installed it will work great for us for years to come.

It would have been great if all the parts came with this generator

Missing parts out of the box. Cannot put the unit together properly. Will try to contact the company after the weekend. Would love to be able to move this unit from where it was delivered but cannot install the wheels without the axle. I hope this isn't what the rest of my experiences are going to be like.

Leaks gasoline like a faucet

I bought a GP7500E that leaks gasoline from the carburetor like a faucet. The same problem with the GP5500 has been well documented on the internet and YouTube, yet the Generac rep I just spoke to on the phone has "never heard of the problem" - apparently cause by a cheaply made corroding float needle. Another company used the same carburetor on their generators, but at least they had the decency to conducting a recall for their customers and send out new carburetor kits. I'll never buy another Generac based on the company's lack of safety concern regarding these leaking carburetors. The service center charges $100 to pick it up under warranty. Thanks, Generac. I'll buy a better made replacement needle for this carburetor from from Honda and repair it myself. Anyone considering purchasing a Generac portable generator should Google "Leaking Generac Carburetor" before purchasing from this company. They're product is an obvious fire hazard. (I doubt you'll post this on your website, but I WILL be posted this review on other retailer websites, too -- just because Generac has "never heard of this float needle problem". Serial# 5978320A

Issues

I would like this generator more if the battery lasted longer and if it would not have problems starting. After 3 batteries I believe I fixed the battery issue. However, sometimes it does not want to start. This is very frustrating when our power goes out. I can eventually start the generator, but it is not easy. And it is almost impossible to start with the pull start. Unfortunately, this generator cannot run our heat pump. That is my bad for not doing enough research. But once it is running, the generator can run everything else in the house. This is important because our house is all electric.

Service and Repair a Must

Purchased this Generac Generator, works great with RV, easy to move around. One thing all Generator owners NEED to remember is that if your Generator breaks down, Somebody has to Repair it. GENERAC Has Excellent Service and REPAIR. Generac is Nation Wide so finding repair service for Genrac is easy. Please Remember this folks. Service is Paramount. My Generac has Not needed repair and probably will Not . Thank You Generac

Feeling good about having a good generator

Purchased the unit in the morning and had it fully loaded up and operating that afternoon. It handled 6kw of electric heat without any issue which would be the maximum load I would expect to have on this generator in winter conditions. I have a generator panel so have the ability to switch load as I need it including heat, water pump,refrigerator, freezer etc. While I'm not looking forward to the next major power outage I do feel much more prepared for that event.
