A Life-Saver!!!

[This review was collected as part of a promotion.] We’ve lost power four times this summer due to intense Philly storms, and I can honestly say the Generac Tri-Fuel Portable Generator 50ST came in clutch every single time. Setup was straightforward, and the tri-fuel option (gasoline, propane, or natural gas) gave us flexibility depending on what we had on hand. We mostly ran it on propane, and it powered everything we needed — fridge, lights, fans, and even the Wi-Fi — without breaking a sweat. The runtime is solid, and the peace of mind it gave us during outages was worth every penny. It’s not the lightest piece of equipment, but it’s built to last and easy to move with the wheels. Noise level is totally manageable for a unit this powerful. If you live in an area prone to storms or unreliable power, this generator is an absolute game-changer. After this summer, I wouldn’t be without it.

I love this awesome product

[This review was collected as part of a promotion.] I received this awesome generator to review. It's the best . The product it's self is great . Looks good and works well. Its well made and heavy, but once the wheels are on its super easy to wheel around and easy to use . This is something every household should have, definitely would recommend it.

It does what it's supposed to

After 35 years at the same address and typically dealing with 1 or 2 mostly short outages per year, we experienced an 8 hour outage and a 5 hour outage within 2 months. My wife said we need a generator! We looked at whole house backup but that seemed like overkill and very expensive. After lots of online research we settled on a Generac in the 6500-8000 watt range. Because we have a well, we needed 230v output. The price difference between 6500 and 8000 was so small, we opted for the GP8000e. The installer put a lockout on our electrical panel so we can switch between generator power or electric service but the generator cannot backfeed the incoming electric. Yesterday we experienced a 5 hour outage. After 30 minutes, I rolled the generator out of the garage and onto my patio. It fired up with electric start even though I had not charged the battery since the initial startup 4 months ago. I hooked up the 30amp cable to the receptacle on the house, switched the lockout on the service entrance to generator power and we had power. In addition to the well pump, furnace fan, and fridge, we ran the microwave, an electric cooktop (not at the same time), and all the lights we wanted. My only complaint, though not unexpected, was the volume. It is loud! My phone sound meter app registered 90db at about 10' away. It was about 8' from our family room and even with the windows closed, it was too loud to watch TV comfortably so we retreated to the basement. It's also quite heavy but I had no real trouble wheeling it around the house from the garage to the patio. Overall, I'm very pleased with it and my wife was happy that we had water and a cold refrigerator during our 5 hour outage.

Superb quality and features

We just moved to a remote area of New Hampshire famous for serious power outages. So of course we had to get a generator for our home back up. This unit is superb. The electric starter is highly efficient and the unit starts up after only a couple cranks and that's in 11 degree Fahrenheit. Follow the simple instructions to set up and you're ready to go. We're having an electrician do the wiring for whole house back up and he strongly endorsed the Generac saying he's had one for 14 years and it's never failed him. We are delighted and secure with our purchase.

It is great!

Just bought this generator after much research on internet, different hardware stores, and electricians. The price is right and our local hardware took the time to gas it up, put in oil and give a demonstration in use. The noise level was certainly acceptable and less than expected after seeing some negative reviews elsewhere on the noise. The ease of portability, electric start as well as pull, and having not to buy wheel kit are extras. The unit started at first flipping of switch. Recommend it highly.

Fired up first pull!

Had to put the wheels on but after topping off with oil and gas this thing fired up first pull. It is somewhat quieter than the Stanley that it replaced. Excellent generator for the money. Output seems to be on the upper end of rating. We run power tools and air compressor of it at jobs site. Works great.

A portable beast

When I decided to purchase my generator, I spoke with a fellow instructor at the JATC. The company he works for is an authorized dealer of Generac and he understood my needs, as my home doesn't have natural gas nor a large propane tank. This generator is basically a whole house generator on wheels but uses gasoline. Assembly was rather easy with basic tools but a friend to help is recommended due to the weight of the unit. Speaking of weight, maneuvering is easy with the large pneumatic tires. Once the fuel system was primed it fires up a moment after the start toggle is pressed. The fuel tank is large, most small cars don't even hold 16 gallons, buy several 5 gallon cans as they are easier to lift/transport. As a licensed electrician I did the install myself and chose not to install a transfer switch but used a main breaker lock-out on my panel. As it sits the generator is not AUTO transfer switch ready but any good electrician could void your warranty and make it work...lol. For being all electric I have a light load of only 44A max per leg and the GP17500E doesn't even bat an eye. Summary.....have basic tools and a friend to help. Higher an electrician to install the proper legal hook-up means. Buy several gas can and rotate the fuel often. Very satisfied with everything.

This Generator is a Life Saver

I live in Louisiana I’m 38 year old dad of three kids that just lost my wife to cancer she was my "high school sweetheart”and loving mother of our kids and our area just recently got hit by Hurricane Laura. The storm took out a 100% of the towns power and knew it would take a long time to restore all the power and we all know how it is with no power so I drove to another town not hit by the hurricane and purchased what I would call a life saver and the best purchase Iv ever made the Generac RS5500 Iv heard nothing but good about this brand so I had to see if it held up to its reputation I got it home it was easy to put together very detailed instructions and steps for operating and maintenance it also came with a heavy duty 220v to 120v extension cord with a 4 way plug in to run your regular extension cords off of and I love they included that with the generator because that cord alone is very expensive to buy and very useful it also came with break in oil to get you started so straight out the box I was impressed but could it run and operate as good as it’s reputation was and I’m here to tell you it 100% did run and operate as good as it’s reputation. The first pull and it cranked right up I plugged in everything we needed and still had more power I could have used off of it. I ran this generator only stopping it for its break in oil change and oil changes and Maintence checks after that. This generator ran like this for two weeks until power was restored and I’m here to tell you as a dad with kids needing to keep them cool and have almost all the functions we would with power this generator did it all even my kids were impressed on how it could run that long and that good and they were happy to see there dad not having to struggle fixing something or seeing the frustration in me of something going wrong or breaking down so that In itself should show any future people looking for a reliable generator easy to operate worry free generator that this is the brand to buy don’t even hesitate on which brand to purchase I’m telling you Generac Generators is the only brand you need to buy unless you want to purchase another brand and have the thought of worrying if it will crank or break down so if you want a worry free piece of equipment that helps your family not only survive but survive comfortably and a brand you can count on then do what this dad did Buy a Generac Generator and your love ones will thank you because it’s not only a Generac it’s a Life Saver!!!!!!!!!!!!!!!

Save your money

What a waste of money. Worked great for the first month, now it won't stay running for more than 20 minutes at a time. Any time you put a load on it, it dies. This seems to be especially true if you have to use it on hot days. (Which when you're using it on an RV is when you need it the most).

GP15000E Leaks Fuel From Between Fuel Vent and Tank

Two days after receiving my GP15000E I filled fuel tank to just below the fuel fill neck (instructions show to fill 1/2" below inside top of tank). I had my generator sitting on my driveway (slightly un-level surface. I started the generator and noticed a lot of gas leaking from between the fuel vapor return valve and top of gas tank (the gas was running down onto the hot exhaust and engine). I quickly hit the shut down button and feel extremely lucky I did not have a fire and explosion. I notice that the fuel vapor valve and tank do not have a good seal to prevent fuel leakage. I have contacted Generac for service.
