I believe it is the best value for the money.

This unit is very easy to set up and use. Ran the electrical system to my breaker box and it does an excellent job. the exhaust is a little noisier than I would like but well worth the money. Very neat machine and no rattles. I would like to see the battery cables re- configured to make the battery easier to hook up because I keep the battery in our home where it is warmer. Maybe clamps instead of the small bolts and nuts for the positive and negative terminals on the battery.

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

Fulfilled all expectations, reliable and convenient.

We live in an area that seems to lose power frequently. The convenience of the battery start was a very compelling feature (it replaced a pull start - I'm 77 and it started to be a challenge) It was such a great experience, I purchased one for my grandson in New Hampshire. Strongly suggest installing an input receptacle connected to your home distribution panel.

Great backup for home office.

I purchased as a backup to provide power to deep freezer, refrigerator, and home office computers. It was easy to connect and provides ample power for my needs. I looked at various generator manufacturers for some time. I decided on Generac because it had the features I needed; was available thru my local service station and could be delivered to my home in time to save my refrigerated food from defrosting. I only need it for 26 hours before utility power was restored. I changed the oil so I am ready for next outage. I estimated that saving the stored food paid for half of the cost of the Generator. Not missing the days work paid for the other half.

A workhorse

I bought THIS generator because of the past experience with the brand, AND because this unit had a larger engine than most of the similarly sized generators. The typical 15kw genset has an 18 to 22 horsepower engine. This model has a 30hp engine!! That extra horsepower means greater power margin for starting loads like HVAC compressors. I calculated that I needed 10kw, and this units 22kw starting capacity exceeded that substantially... But in my experience I need more than the minimum because if the hvac computer crashes because of voltage drop, then starting will fail. You mush have excess power during the starting of the compressor to keep the computers happy. So I picked carefully, and while this one has much more power than I require, the price point and performance thresholds were met by *only* this generator. So I did my first test running the whole house, and this generator handled the load with few problems, but the power was very noisy, very high harmonic distortion. Some things in the house ran fine, but things powered on transformers did not like the power. The home thermostat was inoperable, the computer in the dishwasher crashed, several of the UPS systems did not like the power and complained, and my smart LED lights were very unhappy. Sensitive loads did not like this generator at all... But once I got the thermostat bypassed, the HVAC compressor seemed to run fairly well, though the compressor was noisier than normal. So to meet my needs I decided to buy the largest inverter generator that I could fine to run the house and electronics, and the Generac GP15000E is dedicated to the HVAC compressor *only*. The HVAC blower and electronics run on the inverter generator where they are fed a true sine wave. I didn't set out to buy this much excess capacity, but I still paid less than I would have if I had bought a similarly sized whole home generator, and I have a reconfigurable power plant now so I can handle any need.

solid

heavy and durable. runs forever i would like to see someone try to start this with the recoil rope, though. if someone can actually do it they should probably be in the olympics or barnum and bailey's circus i tried it on fresh fuel and a hot engine ( right after shutting it down ), and there was NO CHANCE of this thing ever starting with the pull cord. keep the battery charged

Good value

Bought for emergency use only, to power a sump pump and maybe a gas fired heating system in winter. Used only once so far, to help a friend during power outage. It started up easily. They were able to run their heating system (hot air), which was nice because temp was down to freezing at night. Since then I tested it one other time during mid-winter, to make sure it would work in cold weather, and it started up no problem. This unit has one duplex outlet with 15 amp breaker. Only enough power for essentials, but that's all I wanted. It is relative small, and one able bodied person can move it if required.

excellent backup

I own a home in Alaska. Power outages are frequent outside the city, and it's dark a lot in the winter. I needed something to power some lights and a portable heater to keep a room warm during extended outages. Excellent bang for my buck. The on/off switch broke the 2nd time I used this unit, but I just went to the hardware store and picked up a toggle switch and wired it in myself. No biggie.

Great product with excellence performance!

I have the above model Generac portable gas generator, still in the box. I am very familiar with this unit as a good friend of mine has the exact same unit. I assisted him in building a house for his family. We used this unit for about 3 months and it fulfilled all of our needs in this house building project. It was used for long periods of time and only turned off for lunch time and never left us without power. After the power company finally installed a temporary pole and electricity to my friends property, we did stop using the unit. Because of its flawless performance I purchased the same generator and I am looking forward to using it...
