Generac reputation

This is my second Generac generator. The first one that I had lasted over 14 years. I sold it because after we sold our house, the new one we purchased was larger, and the 6500 w we used could not power the entire house. So, I sold it for a good price, because it was a Generac, it has a reputation for quality that lasts. This new generator GP15000E has the power to power the entire house! It is heavy, but because it has a solid cage frame on pneumatic wheels, (located in a balanced location) it is fairly easy to move. All the controls are easy to reach and read, and with the electric start, it is effortless! The only drawback is the noise factor, however, almost all gasoline generators are noisy! If this one lasts like the last one, I will have it for a long, long time!

Easy to use. Supplies sufficient power for my needs.

Bought the GP8000e for my ski cabin. It will run everything including well pump and hot water heater when we loose power which has become more frequent. Happy with my purchase. Decided to go with Generac since I already own a Generac generator for my primary home.

Great value

I am a female, own a home and needed a generator I could handle in an emergency. I am able to move this generator, fill it and start it with no problems. It is reasonably quiet. It runs for a significant length of time without needing a refill (+/- 6 hours). During a weeklong power outage during a tropical storm, it kept my refrigerator on, my sump pump going, some lights on and I was able to charge my cell phone. It did everything I needed.

Great Generator

I have been waiting for someone to come out with a generator large enough to have “whole house” capabilities in a portable configuration. I am a self-employed semi-retired electrician and have installed a number of generators, but this one is by far the biggest and best. I bought this one for my own house, replacing a 12,500/9,500 generator that was not quite big enough to run my entire house, especially in the summer with AC. This generator, with 26,500 starting watts and 17,500 continuous duty watts, will run most any normal size house. The only drawback with this is the physical size and weight. It really is too heavy for even 2 people to lift. The saving grace is it’s perfectly weight centered lift ring. I picked it up with a tractor and put it in the back of my truck just to fill the very large gas tank the first time. This really is a 5 star product from a well known and quality manufacturer of generators.

This product has great features

So far I only have had it for a week. It is smaller and lighter when moving it around compared to my old generator. I am slowly checking out all of the cool features it has. I especially like the ability to charge the battery just by plugging it in. and the light that will show when the battery is low. Larry

It exceeds my expectations

I have given this generator a 5 star rating based on my experience with it so far, and so far I haven't needed to use it for the reason it was purchased; to supply emergency power during electrical outages. That having been said, I am impressed with what I have seen so far. The unit arrived in perfect condition, and assembly was easy. I was concerned by the advertised weight at first, but the carton was easily handled by two people, and after assembly, it is easy to move from storage to the driveway where it will be used. The battery was charged when it arrived, and it started right up and ran steadily for about 15 minutes. I had minor difficulty adding the engine oil, in that I had to hunt around for a long necked funnel to use to pour the oil into the unit, no big deal. And, the instructions indicate that you should check the oil level as oil is being added, so as not to overfill the unit. I did this, only to read later that the recommended oil capacity is 1 quart, and exactly one quart of oil was supplied. It would have saved me a few minutes if the instructions said "Pour the 1 quart of enclosed oil into the oil fill plug". Also, no big deal. Finally, it would be nice to have a compartment or something on the unit to hold the battery charger. I solved that problem with a bag attached to the frame with zip ties. If this is all I can find to complain about, I would say that I'm pretty satisfied. I trust that this unit will perform as well when the need arises as it has so far.

This generator is very reliable, started up first time and used during hurricane last summer and 2 times since on short power outages.

Compared several modals, sizes, features, the generac was the best overall. Very reliable, easy to use. Had power through hurricane for refrigerator, window a/c , most house lights, made a 4 day power outage tolerable. Had a 12 hour outage recently, I had just come home from a triple bypass, instructed my wife how to start and she got power to house in matter of minutes. Would not want to be without it.

This generator is really nice and powerfull.

Live in northern Florida, city of Ocala out in horse country and our power grid goes down at least once a month and we also are affected by hurricanes. This generator will power your whole house if required, starts easy, runs quiet for its size. It's real heavy to move around but manageable, I am using the 30A and 50A outlets in tandem to feed my single home electrical panel because the single 50A only gives you 12KW of usable power.

Powerful Generator

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.

Powerful

[This review was collected as part of a promotion.] What a powerful generator, it packs a lot of punch!! Great features like the electrical outlets, the size is compact and convenient and is actually a bit more quiet then I expected (it's not quiet, but definitely not the loudest I have heard) I think everyone would should have something like this for emergency purposes and recreational use. I would absolutely recommend this to all my friends and family.
