Great and reliable product to purchase.

2 of my friends, my sister and I brought the GP6500 Generator 2 days after Hurricane Helene hit our hometown in Georgia September 2024. I assisted 1 of my friend with the assembly process and I assembled both mine and my sister's generator by myself. It was a simple process. Once gas was added to the fuel tank, all of them cranked up on the first pull and stayed running until they either ran out of gas or was turned off manually. The generators was a life saver. They supplied power to what we needed and never failed to perform perfectly. They were used for 6 days before the utility company was able to provide us electricity again. I am now in the process of trying to get a manual transfer switch and power inlet box installed so that I can be more prepared for the next power outage. Thanks Generac.

Great Portable Generator

I have supplied the house through 3 power actual outages since 2013 Dec for short duration's under 12-hours. Run the GP1750E every couple months to make sure it works when needed. Starts up on no more than 2=pulls / and right away when using the electric start. Load Test Run with 3-HP LPAC [Low Pressure Air Compressor 150 psig] for the sand blaster and other lights and equipment in pole barn. Also run Simulated Power Outage Load Test to supply the house VITAL LOADS connected to our 100 Amp Sub-Panel Load Center about 4 times a year. [[Main Breaker Panel is 200 Amp --- Sub Panel is 100 Amp for fuel-oil heat, well water, sump pump, electric water heater, freezers/refrigerators, appliances in kitchen, various lighting circuits.]] Have TV, Computers, MODEM-Router, Printers on their own UPS [Uninterrupted Power Supply] to give me time to setup generator to supply electric to house. Can set-up and power house in about 5-10 minutes. Great Generator for the $$$ --- only regret was I didn't get a 15-KW Generac automatic Stand-By unit --- but I live in the rural area without natural gas and didn't want to invest in propane just for a generator.

Only generator I considered buying.

Great product, well made, starts immediately with electric start. I only ran it for a short time after installing the house electrical transfer panel. Generator handled everything with no problem. I do wish that there would be an oil filter for the engine. I know someone with a 10,000 watt generator and that has an oil filter.

Great generator

I love the generator. It works excellent, just as expected. Starts immediately and runs well; provides the power I need when required. The only complaint I have is the noise level when running. Surely Generac could or should have equipped the generator with a muffler system to quieten the sound emitted.

8000watt Generac generator easy to use and start

[This review was collected as part of a promotion.] Great quality industrial generator. This generator will power our 3 freezers, 2 refrigerators, sump pump, TV's, computers and then some. It's quiet. The handles make it easy to move, even I can move it myself. The self grounding feature is nice. Very fuel efficient. I like that it has a carbon monoxide safety feature. It has a fuel gauge so you can easily tell how much fuel is left. Very easy to use electric start. GFCI outlets with LED indicators are a nice feature. I like that it's made in Wisconsin. I would definitely recommend this generator.

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.

Great product with excellence performance!

I have the above model Generac portable gas generator, still in the box. I am very familiar with this unit as a good friend of mine has the exact same unit. I assisted him in building a house for his family. We used this unit for about 3 months and it fulfilled all of our needs in this house building project. It was used for long periods of time and only turned off for lunch time and never left us without power. After the power company finally installed a temporary pole and electricity to my friends property, we did stop using the unit. Because of its flawless performance I purchased the same generator and I am looking forward to using it...

I was very pleased with this product

The unpacking and assembly were well described and easy to complete with minimal mechanical skills. The engine started right up and power was immediately produced. I let the unit run for a few minutes and then checked the oil level and examined the unit for any leaks or other obvious issues but none were found. I would recommend this product to anyone in need of a large portable generator for emergency or other short term uses.

Works well; good warranty

I bought this product brand new after our home was impacted by Hurricane Helene. The generator worked great, but the fuel gauge was defective, causing a lot of undue stress and complications. It has since been fixed under warranty, but it was not something I thought I would have to deal with.
