We purchased this unit as a whole house generator for those extended outage periods, usually 1-2 per year. Since we do not use gas (propane or LNG), we did not want to install a standby unit on a concrete pad and find a place to hide a couple large tanks. At about half the price including a transfer switch, this unit will power our entire house and we can still store it in the garage or bring it to a family members house in emergency. Keeping 15-20 gallons of extra fuel on hand if stations are out might be a challenge, but for the rare occasions that happens, we'll manage just fine.

I purchased the Generac GP8000E after doing alot of research with several other brands. I am not disappointed, from the moment I started to unpack the generator I noticed the quality of the packaging, which gave me confidence in the product right off the bat. The engineering made assembly very easy! You notice the quality in every part as you put this baby together. The quality shows that Generac and its associates genuinely care about the product they put out to the consumer.

10 year old unit so take this with a grain of salt. This is a great unit and meets all our needs. But it does have one, I'll call it a design flaw. The fuel pump has a ground wire that needs to make good contact with the motor. The end that attaches to the motor is copper or brass and tends to corrode and break contact. Cost me a $100 to have a repair man come out and buff it with sandpaper. Hope they have corrected this.

Great product, well made, starts immediately with electric start. I only ran it for a short time after installing the house electrical transfer panel. Generator handled everything with no problem. I do wish that there would be an oil filter for the engine. I know someone with a 10,000 watt generator and that has an oil filter.

I found the unit to be well made. As big as it was, it is easier to move than I thought it would be. Well balanced. All features are well marked. I purchased the unit for power outage during severe weather. This unit replaces a smaller unit that could not handle all of our needs. The investment will be worth it when we lose power again out here in the country.

I purchased this portable unit about 3 weeks ago, and it is a wonderful generator. I do have a few issues with it though. First off, it is way to loud. I had to build a house for it about 100 ft away from the house to avoid hearing about it from my neighbors. My other issue is being able to read the fuel gauge to know how much fuel is in the tank without me having to look directly inside the tank. I had a GP3250, and it was very easy for me to read the fuel gauge, but the fuel gauge for the 7500E is not reader friendly. Besides those issues, I have to admit that it has a lot of power to keep your house powered up for a lengthy period of time.

I live in Puerto Rico, and since Hurricane María destroyed our power grid, almost 5 years later we are still having constant island-wide blackouts. The most recent in April, 2022, all the generating power plants on the island shut down due to a fire in a switch yard. Four days later, half the island is still without power, including us. I've used it once before during a brief blackout and it did well. Today it looks like we're going to be without power for at least another 24 hours (I had power restored two days ago but today it went out again). I plugged it in to the house with a manual transfer switch. Right now it's nightfall, and I am running two refrigerators, kitchen and living room lights, all ceiling fans running, and not a hiccup from the set. The electrician that installed the transfer switch says that if power doesn't come back later, I could turn off the refrigerators and turn on one bedroom inverter mini-split air conditioner. Thoroughly satisfied with this product. Thank you Generac. Now buying a whole house automatic propane or diesel set and/or a Powerwall with Generac seems like a wise investment. Until then, this GP6500 will do just fine.

I looked all over and this is deffinetly the best generator for the money. You won't find a generator of this quality at a lower price. Took about 10 minutes to put everything together and I had the generator running in no time. The extra oil filter and air filter are a nice touch. Very pleased with my purchase. I expect this generator to give me many years of service and peace of mind.

Bought this generator during a storm where half our province was out of power for over a week. I utilize it as a whole home backup generator, it has enough power to run my well pump and sump pump as well as heating my water when I need it to. it starts right up without hesitation and runs smoothly. The frame and wheels are very rugged to carry it around since it is on the heavy side. the only down fall that I found with it was that it is quite noisy so I will be building an insulated cover for it. Extremely satisfied, never looked back.

The generator came with oil and clear instructions for assembly and operation. It starts very easily and has operated dependably each time I needed it. I had to call customer service to register my warranty and the person I spoke with was very friendly, spoke clear english and took care of everything I needed. Overall I am very happy with my purchase and would strongly recommend this product.
