Generac 5943 GP7500E 7,500 Watt 420cc OHV Portable Gas Powered Generator with Electric Start
Power the fun stuff or cover an emergency with a GP Series portable generator. Affordable reliability and features not usually found on basic portable models make these a favorite for home use, camping, job sites or outdoor events.
Reliability From the Start
Because of Generac’s focus on power generation, we know how to design an engine that can stand up to the long hours of continuous use generators can be required to run. Cast iron cylinders add longevity, not found on every portable generator engine.
Easily Accessible Controls
A portable generator needs to be ready for use at all times. Generac added maintenance reminders on the hour meter, so scheduled maintenance is easy to track, and the convenient fuel gauge provides at-a-glance fuel monitoring. Many portable models have controls located in inconvenient locations and are difficult to access quickly, especially in the dark. We gave control placement careful consideration, with comprehensive control sets conveniently located for easy access.
Framed for Durability
The hardened steel frame gives our portable generator cradles added strength and are a premium 1¼” thick, a full ¼” thicker in diameter than competitors' models. The addition of integrated brackets and impact resistant corners on most models gives contractors rugged options ideal for job site use.
Top Customer Reviews
While the generator runs well, starting it is tricky. The choke throttle is not at all calibrated, so its difficult to start and keep running until its warmed up. I actually killed the battery trying to start it and had to jump it to my car.Other than starting it, its pretty simple to operate.
Engine maintenance is required after the first 50-hours of run-time. if you're not comfortable with removing the valve covers and making those adjustments, be prepared to hire someone to do it. Hopefully, you won't need to haul the 400+ lb generator to a service center.
I like the unit, but don't love it. Its a great price for 17KW, but very rough around the edges.
This unit's muffler quiets down the exhaust noise surprisingly well. In-fact the most prominent noise coming from this unit, comes from the engine's mechanical noise and forced-air fan. When the idle control is enabled the generator spins down and gets really, comfortably quiet. When the idle control senses a load, it spins the engine back up to full speed.
Plugged it into our inlet box via it's L14-30R socket, flipped every circuit over including our 65LRA/240V central air conditioner which connects to the generator via the sub-panel. Turned on every load I could think of, then engaged the A/C. I almost didn't notice when the 15,600w startup load from the A/C hit the generator, all I heard literally was a half second blip in engine noise.... in other words... with all the loads we currently have wired in (~8000w)... it was able to power them easily from a L14-30 plug... nice! It will be interesting when the L14-50 gets wired in and we add more circuits on the sub-panel.
To deal with the noise, I'll be building a small shed for this unit, near the house. I'm on the fence as to whether I'll attach a secondary muffler to this unit, since the exhaust itself, is already pretty quite.
The one draw back on this unit is that it consumes a good portion of fuel... 16 gallons in 10 hours @ 50% load.
Since my original post, I did purchase a Walker Exhaust 22266 Quiet-FlowSS Muffler to use as a secondary muffler. Along, with some WALKER EXHAUST 40002 to connect the generac to the muffler... it's made HUGE difference in terms of quieting down the exhaust noise. BTW, the muffler exhaust port on this generator has an outer diameter (O.D.) of 1.5" inches.
Keeping in mind that this thing weights 390lbs, I decided to build a small shed for this generator so that we'd have it available for use in extremely bad weather (where it would be difficult to roll this thing into position...). Also, while the muffler does an excellent job at quieting down the exhaust noise, the shed serves to cut down on this generator's air cooling induction fan & engine noise, as well.
We ran 4 THWN 6 gauge cables ( through 2" SCHD 40 PVC conduit, 18" inches underground...) from the shed to our home, to support full 50 amp 240V service from the generator. Yes, this generator puts out a total of 72AMps at 240V, if we want to use that extra power in the future, I'll have to pull additional wires through our conduit and hook up to one of the generator's other power outlets. We also ran 2 THWN 10 gauge cables, from our home to the shed, to support a 20 amp 120v circuit. This circuit we use primarily to keep the generator's starter battery fully charged, it also provides us with a heavy duty outdoor outlet on that side of home, which comes in handy.
In terms of performance, we've had a brief power outage recently, and the generator, inside it's shed, has worked flawlessly.
Lost power during Hurricane Sandy, for about 20 Hours. Generator ran the entire time, without a problem. First long duration run. My wife, daughter and I were VERY happy with the outcome. Worth every penny.
Like the other reviews, this unit is big and heavy duty. Its made in America and the craftmanships reflects it. Nothing about this portable generator is light duty... The other unit I considered was a Large Honda from a dealer in town but at $4600 and smaller in every way it was not a contender in the end. Gererac's parent company is Briggs and Stratton and their small engines are among the best in the world which was also a confidence builder.
My generator arrived by a large motor frieght box truck to big for my driveway so I transfered it from their truck to my Explorer Sport Trac. So yes it will easily fit in a small truck like a S10 or Ranger. I left the generator in the truck bed on the small pallet it was shipped on and using a few blocks of wood and a 2X4 to lift it I easily installed the wheels and handle. Using a set of truck ramps I wheeled it off the truck onto my garage floor. Again this is a large, bulky and heavy unit that maybe two strong men could lift off the truck. But I did not want to risk this thing falling, it cost way to much to risk anything. I worked with a wheel barrow on a farm for many years so I was sure I could handle the ramps, but once we headed down the ramp it was all about control because there was no stopping.
I will update this if there are any surpises, however there is no storm or outage in the forcast. I have yet to convert the Power Panal. And I expect to start the unit this weekend for a breakin period before the first needed run. I installed the oil supplied, will hook up the battery and refresh its charge, and add about six hours of fuel for the first run. I have to give it five stars, there nothing that makes this unit less. Its like the F350 of pickup trucks, you only buy one if you really need it for super duty use.
Oct 2014, I finally was able to get an electician out to install the transfer switch on my power box, so fewer cords to run. Here is some additional information on the generator that most people will find helpful. First of all the large 50 amp plug is great for powering my panel, but it won't supply the entire house if everything comes on at once. So I had to pick and choose what would get power first. But the front of the panel has several other 30 amp and 120 volt outlets that I can run other cords to power my extra stuff like a deep freezer, garage refriderator, etc. So if you have a potential large power need like me then this unit could be the unit for you.
I also attached a small solar battery tender that keeps this battery in top shape and has turned over without fail even in the coldest weather. While plug in units are available I like the these as they tend to cook the battery less (opinion, and are more green.
I have had absolutely no problems with the location of the outlets, especially the 50 amp.
