Great Features and Value, but lacking in Documentation

I really think you did a good job designing this product. The Maintenance will be quite easy based on how it;s designed. I really like that the Oil Filter, & Air Filters are VERY EASY to access. Changing Oil with the attached discharge hose will be Easy & Clean. That being said, I really don't understand what you provide such useless Documentation. The assembly details are so Tiny I had to use a Mangnifier to be able to see them. Additionally the Hardware defined in many locations was not the Hardware required. It's really no n=more expensive to provide GOOD Documentation than it is to provide Poor Documentation. Additionally, I was missing Hardware, and had other Hardware that was not used. The instructions are Vague & unclear for anyone who has not assembled oner of these already. That part really needs to be rewriten!

great generator

Great generator for the price! easy set up. It also will be easy to maintain.Easy to start. just to see what i could run with it i put it through its paces. I ran 5 lights, 2 fans, 3 electric heaters, well pump, refrigerator, freezer, heat lamp, garage door opener. it ran all of it without any problem. I was bold enough to run all the above and turn on the hot water tank. now thats when the generator knew it had a load on it for sure. overall great product! its all i need if the power goes out. its even wife friendly.

GP7500E Portable Gen. Runs well but......

Ever since I bought this in May of 2014, I have yet to get it started using the battery. I can pull start it but my wife can't due to the fact it's pretty hard to pull start. Battery doesn't even turn over the motor even after a full charge. Called customer service today and they were helpful but now I have to bring to get it fixed at a authorized dealer.

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.

GP15500 EFI *DISAPPOINTED *

I purchased and received my GP15500 EFI on July 11, 2023. I purchased the unit to supply supplemental power to my home, as we experience frequent multi-day power outages due to severe weather. As of yesterday, 07/29/23, we were subject to severe weather and lost power. I fired the generator up and started supplying power to my home. The unit worked flawlessly for 10 hours, getting me through the night. Woke up this morning, 07/30/23, and shut the unit down to let it cool before refueling. Went to get more fuel and when I returned home (30 mins later) I found that the top portion of the fuel tank imploded and collapsed on itself. I am in complete disbelief. This was supposed to be a reliable piece of equipment and at $4,000.00 I expected more. Yes, the unit is covered under warranty. However, no Generac certified repair shop is open on a Sunday and I estimate not having my equipment back for several weeks, figuring new parts will have to be ordered. The unit was assembled and maintained according to the manufacturer's manual (i.e, oil level, fresh fuel, proper storage, etc.) And only has 11.2 hours of run time. I went with Generac because of their exceptional reputation but now regret my purchase, as I have a $4,000.00 paper weight and no power. I may update this review once my equipment is repaired but fear I will run into the same issue in the future. I tried to add photos but I am unable to do so.

Very Good Unit

No big complaints. Strong powerful seemingly well built machine that delivers consistent power. I ran it continuously for 16 hours on 1 tank @ 1500/2000 watts. With cycling stuff on and off run time easily should go over a day. Things I don't like, battery doesn't charge while running the generator and no fuel drain valve.

wasn't allowed natural gas or propane

I needed to run my entire home inn case of a Hurricane. This was the only generator gas powered to accommodate our needs. 50 amp service was more than enough, ran my entire home for almost 3 days till power was restored. I was extremely happy. I referred this model GP17500E to a friend he bought one and like me very happy thank god we didn't need it so far in 2018.

Should do the job easily

I bought it for emergency power for when our tree lined street takes out the power lines. I've only run it for a few minutes so far, to test the breaker box connection. It ran the well pump, furnace, and a few lights without issue. There will be enough power in reserve to keep us comfortable if we have another snow disaster this winter.

Small wonder

[This review was collected as part of a promotion.] Generac GP 3600 is a small wonder. The size is perfect for portability to carry with us on our camping trip. Fuel consumption is plus point, and being able to store perfectly when not in use is another advantage. Additionally i can use it for my some project around my house and as backup in case of emergency.

This Product has Great Features

I have owned a 5000 watt Generac generator for almost twenty years and it has never let me down. It has a rope start on it and my wife and I both are now in our seventies and have difficulty pulling the rope to start it. I felt it was time to get a another generator with electric start. I purchased the Generac 7500E and it starts beautifully. This product has some great features. I like the low noise level, the ease of operation and the features like the hour meter, the built in gas gauge, battery charger and outlet covers. I use it for home back up. I know that I will be protected in an emergency. Great Product!! Roger 73
