Hurricane Dorian

Purchased this unit just prior to hurricane hitting Nova Scotia. We lost power for three and a half days. This unit kept all the essentials running and kept us safe and dry. Didn't run it over night, but pretty much all of the waking hours and only had to refill the fuel tank once. No super heavy loads but it handled the refrigerator with no problems. Used it for coffee, microwave, induction cooktop, TV and internet. Delighted with the unit.

Outstanding.

I have had this generator since February 2017, the peace of mind is priceless. I did look tirelessly and this model was the best value. It easily handles our home ( 4200 sq ft) multiple refrigerators and 2 central air units. I did have the electrician wire the house for takeover, much easier given the winters in New England. Easy install, unpack and setup, by myself. Best of all made in the USA, great network of service centers here as well. If you, like me are looking for an alternative portable power source, this is it

GREAT GENERATOR--EXCEEDED MY EXPECTATIONS!

Assembly took less than 30-minutes and it started effortlessly right out of the box. A “field test” of the new generator was conducted two days later. After a two hour test run, with all the transfer panel breakers turned on, and nearly every component of a “normal load” placed on the generator--from the well pump to the dishwasher, and from the furnace to the refrigerator & water heater--the GP7500E generator handled the load effortlessly. However, I've recently discovered one issue that remains distressing. In the owner's manual, Generac DOES NOT recommend running the generator in rain or snow. This is equivalent to a "Catch 22" in back-up, emergency power! After all, inclement weather--blizzards, hurricanes, tornados, ice storms, etc--are the causes of power outages in the first place creating the need for back-up generators! So the food in your refrigerator must spoil because it's raining outside? Really?

Unbelievable performance and reliability!

I've owned this generator since April 2013 and have used it to its limits with zero issues and 100% satisfaction on my part. We started construction on a new home 2 months (June 2013) after our purchase and due to our utility company's inability to bring power to our rural location until August, we were forced to use the GP17500E to supply power to all of our contractors. We put 200 plus hours on this baby throughout the concrete, framing, electrical and plumbing rough in, and getting about half the shingles installed. Big cost on Gasoline, but kept us on schedule and everyone working. It now serves as a whole home emergency backup power supply for virtually every circuit in my home through the 6380 Manual Transfer Switch. 2000 square foot home with a geothermal heat pump and 4 ton A/C, all lights, power outlets, appliances, hot water, entertainment system, computer. It's easy to operate and switch between Utility power and Generac. We are conservative on power usage during outages, but incredibly comfortable during our Kansas winters and summers!!! I will never be without one of these generators on hand and wouldn't even consider another brand.

Awesome Generator

Great quality product as expected from Generac! Runs everything I need during a power outage with ease! After buying portable Generac I'm even more convinced to purchase a standby down the road! Then I'll be able to camp and tailgate exclusively with my GP6500!

Has all the features to keep our lights on

[This review was collected as part of a promotion.] Glad to have this Generac 8000 Watt Portable Generator on hand and ready for the bad weather season. We just bought our home in a very windy/snow-laden area and having a back up generator is the way to go. It took a few hours to assemble and we found that we needed to go get an additional cord, but once we did that, it started up without issue. The built in maintenance timer is great - makes it convenient to know when to change the oil, etc. The wheels truly are heavy duty. We're feeling confident that if we need it, we'll be able to keep the lights and power going for our kids without issue.

From delivery to operation the instructions are very easy to follow and assembly went quickly. Generator is very easy to operate

I have already put the generator to use and it works like a champ. No bogging down even under high AMP. Very impressed, really not as noisy as I feared, and the easy on off makes operating it a breeze. Very low fuel consumption which made it even better for the overall cost. I have looked into service the generator myself and this should be just as easy. Overall best generator I have come across

Easy to use, reasonably priced, Gets the job done nicely!

I already had to use my generator, because the local substation near us was shut down for about eight hours. had it up and running in about 15 minutes and ran 80-90% of the house without interuptions. Very pleased with this generator! I would highly recommend this generator!

Perfect for RV Owners!

[This review was collected as part of a promotion.] The 3600 is perfect for supplying power to our 32' RV on those trips where electrical hookups are not available. This is also a great addition to any home workshop and a nice item to have for any short or long-term power outage. Here in NC foothills we have a week 2 hurricanes drop 5 or more inches of rain in a short period. We fortunate that our power did not got out but others close by had outages that lasted several days.

Awesome Generator!

I've only had this generator for a little while now. It seems to be performing very well. I bought it mainly for the 240v. feature to run our well pump during power outages. I ran the pump on it to make sure it works and it did indeed work fine. We'll never be without water now!!
