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.
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!
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.
Awesome
This has saved my bacon 4 or 5 times. I almost wish for a storm to come now because I'm prepared. I hadn't used it for a year and I ran it yesterday as a test and it started up right away. It kinda scared twice though. The first time I ran it it burned almost a quart of oil. And then once I filled it up with gas and I hadn't turned the fuel shut off valve to off and somehow the some of the gasoline went into the crankshaft. They don't tell you that in the manual. And now the manual says paper air filter but mine is foam. But ,I still love it and chain it up when not in use.
To close for comfort
Just bought my RS8,000E unit. Easy to assemble. Love the easy start push button. Like the back up pull cord-(if needed). Very heavy unit. Huge fuel tank capacity. We lost power 2 days ago from a storm and looks like couple more days will be out. Not gonna waste $500+ meat in deep freezer, $200+ in refrigerated/freezer indoors to thawing. Bought this unit, ran home, set up, plugged all our stuff in. Saved the day Generac...**** P.S. I should have read the directions better on spacing. All hooked up, running, chained the unit to the fence, and was 2 ft away from my garage siding. After 1.5 hrs running smelled a strange smell in air. Couldn't find it till we we looked at Generator again...... My garage vinyal siding was melting. The exhaust was blowing hot, melting my siding. Arggg. Guess I missed the part of keep 10 ft clearance all around. (Too close for comfort). Still runs great.
Best " bang for the buck"
After researching and using other products, such as Honda. I could not help but know that my GP6500 is the best bang for the buck! I know the dependability of generac having owned one in the past ( used it as an enticement on sale of my previous home). This particular model will also give a surge of power when increase of load is needed . With proper maintenance there is no reason it should not last a very long time. Very comforting to know the dependability of the generac name. Living in Florida having dependable back up power is essential. Sleeping better knowing I now have it!
Perfect for us
[This review was collected as part of a promotion.] I've owned two Generac generators in the past (traded up) and always been pleased with their performance. Lately it's been harder to pull a generator for me, so when I found one with a push start I jumped at the chance. You're going to need some help with this as it is quite heavy but assembly was easy and after that I could pull it on my own. We typically run our sump pump and freezers when the power goes out and run a cord upstairs to plug in the fridge and charge our phones/electronics. I tested it out and it had no problem with that load. I'd compare the sound to that of a lawn mower, loud, but if you're inside it's not going to bother you. The start is a breeze, I can't believe all the pulling I used to do. I feel a lot better knowing that if the power does go out for an extended period of time, especially with winter coming up, we'll have everything we need to keep us safe and warm.
It powered the home for 7 1/2 Days
I bought this generator to power the home during those temporary power outages due to thunder storms. Then Hurricane IAN devastated our part of SW Florida. It was September 30, and I couldn't even go outside to set up and start the generator until 11 PM, when the winds dropped to 50 MPH. I bought the General GP-17500 to make sure, "IF", I ever ran the generator for a couple of days, it would have power capacity to spare. This generator powered the entire home for 7 1/2 days. I shut it down during the afternoon to cool it off, check the oil, and fuel it up for the overnight operation. And yes, I changed the oil and oil filter two times within the 7 1/2 days. Me being me, I even placed/positioned two floor fans to move air across the unit to ensure full cooling of the engine and generator. Like in tornado areas, once IAN caused its damage, the weather in SWFL was incredibility perfect. Low humidity, Low Dew-point, cooler than normal hovering around 75 all day, and cooler at night, for the next 12 days. I had wired this generator to back feed the electrical panel though a mechanical interlock and a 50 amp breaker. The main breaker must be moved to the off position, then the mechanical interlock plate is moved up, allowing the 50 amp breaker to be turned on. And when we needed hot water, we would turn off the home AC, then switch on the electric hot water heater for about 45 minutes, then the hot water heater was switched off again. We did not want to test the full power capacity of the generator, but it powered the two home AC units, the well pump, and when needed, the clothes washer and electric clothes dryer. Here too, we always powered down other high current devices like the AC units, and hot water heater, when washing and drying our clothes. For a "portable generator" bought to power the home for a few hours when a thunderstorm and winds temporarily knocked out the local power company feed, this generator performed well beyond expectations. Our next purchase will be a Generac backup Home standby generator. We now want this style unit so when there is a power disruption, the generator will taker over automatically, and I don't need to send my wife outside with the flashlight, instructions on how to position, connect and start up this unit. (Yea, listen to my big talk here. I do all of this, moving, connection and starting, but now see the wisdom of a built in home standby generator, since we recently moved to SW Florida I will start by getting a propane tank sunk into the ground, our HOA rules require this, and once in, we'll order the Generac unit with transfer switch. And "NO" we will keep the portable generator for a bit as a portable back-up generator to next to be installed backup home generator. I figured it was time to give feedback to those still on the fence.
This product fulfilled my needs
It was easy to put together, add wheels, handles, added oil/gas. Even though it has electric start, just before starting, I pulled the cord very lightly just to ensure the oil was distributed, the unit started! Very reliable! The electric start works too. Would recommend.
Works
I bought this to power a off grid cabin in conjunction with a power inverter... it powers all my lights , TV, side by side fridge and a out house with lights and 1500 watt heater.. I'm in Alaska... my only COMPLAINT is the choke... it simply will not start , warm , cold or hot...without choking it!.. I run it for hrs at a time...turn it off and whether I restart IMMEDIATELY, IN A HOUR OR THE NEXT DAY... gatta choke it... makes NO SENSE...slightly loud... fuel consumption is decent...good machine... would have bought something else, but.. in Alaska variety is limited..shipping is costly so had to buy local...would really like wireless start... not available on generac
