So got I bought a second one

We purchased our 1st machine back in 2011. Still runs great, but needed a second one. So we got another Generac. Assembly was quick and easy. Directions were very detailed. Our old one takes a beating and never fails us. I would recommend this product to anyone who asks about generators.

So Far So Good

I just purchased the GP7500E for emergency backup for our house. We experience several power outages during the winter. This is my first purchase of a portable generator. It was easy to assemble. I added oil and gas, turned on the fuel, set the choke, pushed the start button and it started right away. It even comes with a battery charger. This will be the perfect back up power for us. It is a little louder than I had hoped but, we can get over that when the first outage happens and we have power in the house. It is connected to a manual transfer panel and the change from hydro to back up is very easy to accomplish. Come on winter storms!!

Best purchase EVER! GREAT!

I just bought this generator the day before this huge blizzard we lost power and this thing ran like a champ! Extremely easy set up, put the oil in it and gas in it like they said one pull and this thing fired right up. This generator literally ran our entire house no problems! So if you're looking for a reliable well priced good little portable generator, this is the one you want!

Awesome unit

I purchased this for my mom after the recent hurricane. She's in her 70s with medical issues and this unit has made her comfortable in her home. It's running 4 ceiling fans and three 110 ac units plus the house lighting and it's not even straining at all. Thanks for a great product.

Smooth as Silk!

Two weeks after installation of the generator and the GenTran switch we were hit with the "great November snow" in New England. Some people in CT were out of power for 9 days or more. We were out for the 10 minutes it took for me to wheel the generator out, plug it in, start it, and shift circuits to it. SMOOTH! Never a hitch or a glitch. I LOVE it!

A really fine product

Ordered my Generac GP17500E after researching on-line and talking with friends who have Generac generators. To my surprise, it was ready for delivery in 1 day. Uncrated and assembled it in about 2 hours (instructions were good but could be more user friendly) and was impressed with the quality of construction. The supplied oil, spare filter, spark plug, etc., were added value. Very pleased with this generator and have recommended Generac to family and friends.

Great for emergency power

I am a 65 yo woman who needed son to do initial set up before Hurricane Irene. After that I was able to service my generator myself. It ran window air conditioner, tv, computer and refrigerator and some lights, I am very pleased and recommend this product.

Both tires don't hold air. Oil bottle opened during shipping and was over everything. Had to buy locking nuts to mount handle. Looks like a "tickle

When I opened the parts package there was oil over everything. Pumped up a flat tire and now both are flat. Had to purchase locking nuts to install the handle. It appears to work well, but your detail and instruction booklet leaves much to be desired. This replaces a 15-year-old 15KW unit, so am confident that it will perform well. Along with a spare air filter there was what appeared to be a "tickler" cable/plug, but no place on the generator to plug it in (when & if needed to restore the magnetic generator load).

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.

Great unit!

We have had the 17500 for a few years now and it has been great for us. We live near a national forest so when power goes out it generally stays out for several hours to several days. We do the regular maintenance on her and have a trickle charge solar panel on the battery. It definitely burns through fuel, however, it runs EVERYTHING. Also is very heavy, so have so.e strong people around if you need to move it or place it strategically and then buy a sturdy after market cover to keep it out of the elements.
