Seems quite good at this point.

Have only run a few tests in the first 3 days of owning. Time will tell as to reliability and durability. Price reasonable. Noise level is pretty high but placement is critical. and in our case not a significant issue. Looked at others, but this seemed to exhibit best combination of size,price,reputation,and warranty. So far so good.

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.

Great generator. Manual needs improvement.

Excellent performance immediately after first start. Just what we need for sump pump power. Although assembly is not difficult, the manual for assembly could be improved: The parts could be better identified, and the pictures are too small to be of any help.

First Generac

It is a little noisier than expected. But for 7500 watts and the portability, it is no issue at all. I've had other brands of generators in the past, and the quality of Generac has exceeded my expectations. As a homeowner and Master Electrician I give it an A+

Was a lifesaver when needed.

A derecho came through our city on August 10, 2020. Severely damaging the power grid to the city. I purchased a RS8000E the following day. I needed the unit to run a refrigerator and freezer, but more importantly my mothers oxygen generator. We were without power for eight days. The only issue I had was with the user manual no specifying that flipping the 30 amp circuit breaker need to be turned on to activate the two 120V outlets. I figured it out and had no issues with the generator. The generator definitely paid for itself. I would recommended this unit to anyone.

Good price excellent product

Have installed and maintained Generac Whole home generators. So I am familiar with the quality , ease of Operation and maintenance of Generac products. Bought this for home backup After electrical outage. And with ice storm on its back fully anticipate using it. Am pleased with what I've seen and will add another review if I use it with my thoughts on product.

Great product for price

I needed a generator that could power the 240v well pump as well as a few outlets and refrigerator during any power output. This Generac model came up at a great price, I could not pass it up. Unit looks basic, but has all the features and power I needed. Assembling the unit is simply other than the cotter pins for the wheels. Simpler bow tie cotter pins would have made things easier due to the restricted space due to the battery. An internal charging system that would charge the battery while operating would have also been nice. Unit is quite for the power rating. Unit is heavy, so bring a helper when you buy.

Generac GP18000EFI

The generator is being used to charge batteries and run a small cottage at the same time. No complaints about weight and size as it's expected. It fired right up and started going to work. The only problem we have encountered is the 30AMP breaker keeps tripping if we run small window air conditioners (5AMP) or anything at 1,500 watts=12.5AMPs for a brief 5 min. The offgrid includes four banks of 48V AGM batteries. We set the Magnum inverter down to 80% and AMPs down to 38. This seems to be helping but we can't put a larger load on. So we installing a 50AMP plug on the house with a cut off and bipass, essentially we will be running the 30AMP plug to charge the batteries and the 50AMP to run the house. Typical charge on those batteries is around 4 hours. If you plug an appliance at 12.5 AMPs direct to the generator - there's no difference in load sound. As a building contractor we designed our own off grid system and will be writing a book with as much detail as possible.

Good quality

This generator is amazingly easy to start. I put oil and gas in it and slowly pulled the cord to make sure the engine would turn over freely and it started right up. The only reason I did not give it five stars is because the gas fill cap is in the center of the tank. If it was located closer to the side it would be much easier to add fuel to the tank without spilling it.

Great generator for power backup

I purchased the GP7500E to replace a smaller 3250 generator to provide backup power for my house. Last December we had a power outage in the middle of a winter storm, the smaller generator worked for a few items, but I wanted to power more circuits in the house. I installed a transfer switch so I can power the furnace, refrigerator, TV, computer and several lights in the house I assembled the generator, added oil, gas and connected the battery. It fired up right away! I definitely like the battery start! I did a test run on the house and everything powered up as expected, now to wait for the next power outage.
