A "POWERHOUSE" generator

This generator is an excellent choice for backup electricity, once outages take place. I live in Florida, home of the hurricanes and when the power is gone, homes inside become 88-92 degrees warm. After this last hurricane, I said no more ... so decided to invest in not only a generator but the top free standing generator I could buy. This "Bear" as I call it ... can power the following just off the 50 amp take; 4 ton a/c, two refrigerators, microwave, TV, all lighting in the home, garage door openers. I can turn on the stove as long as the a/c unit is off. Oh ... and I supply my neighbor with a 30 amp outlet for his refrigerator and fans. The "Bear" doesn't even flinch. Two neighbors have already come by and have asked me for information on where I purchased "The Bear". There is one set back I found when assembling the electrical connections. The 50 amp receptacle located underneath the electrical panel on the generator is placed with the ground connection located at "9-o'clock". So, in order for your plug to function correctly and capable of using the safety metal pin in case of disengagement, you must use a "50 amp round male plug". Only way you can keep the proper alignment. Otherwise, by using the common 50 amp plug, the cord will be laying off to the side of the muffler where it becomes very, very hot for obvious reasons. I did not find any information as to the set up or 50 amp plugs to be used while assembling. Otherwise, this is a great generator and I am very proud of my "Made in U.S.A." product. "Quality you can see, quality you can test … because it is quality at its best".

everything I hoped for

the 7500e arrived on time and within an hour it was setup and tested. it starts immediately and purrs like a kitten. when we did a load test we were happily surprised. the watt meters showed that we could comfortably operate our home with power to spare. the value we derived from this purchase will give us years of electrical security. thanks Generac for a product well done1

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.

Won't start.

I bought it at Sam's Club (06 JUN 22) and assembled it per the instructions. I fired it up once and it ran for a few minutes. When I shut it down and attempted to restart it, it wouldn't fire. It just makes backfiring noises. It still doesn't start or run. Needless to say, I am not pleased! Your phone rep was supposed to forward me a list of authorized repair shops, but I have yet to receive it. I want my generator to run in event of a power loss. Please help me to reconcile this situation.

It's a great generator but.....

I bought this GP8000E to replace an older other brand with lesser capacity. It starts instantly and performs wonderfully but on day two I moved it on my trailer and after it had experienced a few bumps on the road I discovered that the fragile welds on the axle brackets had broken and bent on both sides. To properly weld them the unit had to be laid on each side resulting in oil spill etc. It was disappointing to see a unit with so much quality in other areas to fail on something so simple.

Great features

[This review was collected as part of a promotion.] We trust the Generac name. It was easy to assemble out of the box. Portability is great as it comes with never flat wheels. Fired right up and I am impressed with the quietness of the unit. I was expecting it to be much louder. Have only ran it a handful of times, but I have not came across any issues. We live in Tornado Alley and this will be a blessing during storms, however this is also great for job sites.

Solid Heavy Unit

I bought this unit last year to run my new 24 ft. concessions trailer G-Dub's Grub which I opened 2 weeks ago. I have worked 2 large events with 20 hrs on meter. It runs the 30 amp service easily-- lights, water heater, water pump, fridge etc. All filters, oil drain, spark plug easy to get to, which is a big reason why I bought it. Getting ready to change to Mobil 1 10W-30 synthetic w/ extra Generac filter sent with unit. I use 89 grade non-ethanol fuel. Multiple power options here folks. Heavy USA made unit. My problem with this unit is it's too heavy for me and staff (female) to handle 390 lbs. Overkill on my part. Just bought extended warranty plan last month. Weighing my options.

I cant give a review since I have not been able to check the equipment.

Out of failure. As soon as I pour gas into the gas tank it start to run out onto the battery, the leak is next to the shut off valve. I immediately customer service @ 888 436 3722 to report the issue the gas tank was leaking above the battery. rep wanted to know if the tank was crack I told her I did not know. The rep then activate the extended warranty then give me two Authorized Generac Service Dealers. I call the service dealer who instructed me to contact the Merchant i purchased the Generator from, since it is a out of box failure. Photo and video attached.

The Power Came on Just Before We Fired It Up!

We were into a two day power outage and the temperature was in the 20's. Called ahead and paid over the phone - picked Generac because of the name and quality. Drove 70 miles and picked it up and by the time I got home I was too tired to put it together. It got down to 13, but our propane stove kept us warm - put our food outside! Got the generator put together and the power came on! Took a break, added oil and cranked w/o gas to make sure everything was oiled good and it started! Filled with gas and started on the first crank. Plugged in 2 space heaters and the truck engine heater and let it run for an hour and a half to break it in for next time. Plugged in the battery charger and charged for 24 hours to make sure it is ready to go - really like the battery start feature! Great purchase for us - we have been wanting to get one. (Your program won't let me post a 4 X 6 photo.)

A Great Portable Generator

New model from Generac. Assembly of the unit was amazingly simple. Directions were very clear except the exclusion of the guideline to attach the spark plug connection to the spark plug, I assumed this was already done before shipping. Start up was very quick and easy. Tested the generator and it ran well and meets all my needs and expectation. Sleek appearance and many great features
