a couple of suggestions

Putting the machine together in a cold garage was a real "thrill". None of your vendors offered this service. The cotter key for the wheels is a real challenge. There has to be a better, easier way to do this little task. Many naughty words were said. For accessories, why not casters for the front of the machine?? Something designed by you, designed to fit properly, would be a nice feature. Try lifting this thing to pull it out of a garage when you are 70, with a bad back. Everything works as it should, and the directions are easy to follow, and it started the first time.

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.

A Great Portable Generator

New model from Generac. Assembly of the unit was amazingly simple. Directions were very clear except the exclusion of the guideline to attach the spark plug connection to the spark plug, I assumed this was already done before shipping. Start up was very quick and easy. Tested the generator and it ran well and meets all my needs and expectation. Sleek appearance and many great features

Quick Start, solidly built

I live in the Northeast corridor and have decided this wacky weather is no fun w/o electricity. Purchased the GP6500E w/ manual transfer kit. Assembly was easy. Started right up w/ the electric ignition. Contracted a local electrician to install the transfer box. Straight forward and no surprises, other than needing a 60 amp main breaker. Electrician commented on the box and said the set-up was pretty slick. Prepared and waiting for Mother Natures next haymaker.

BIG....REALLY BIG

This generator arrived in perfect condition. Great packaging and easy to unpack. Assembly of the handle, wheels and rear prop are required. Also the battery hook up and adding oil. Caution (I had to drain some because I rushed the fill and by the time it all settled it was over the fill line) Take your time. There is a replacement air filter and pre-filter as well as a new oil filter provided. Break in period of 30 hours. I have yet to run it but it is really well put together and I will write another review after the break in period. The recommendation is to run the unit for one hour every 30 days. This will keep it charged and ready to go. I would recommend this unit to anyone who wants a whole house generator as it is the largest wattage available in a protable and I don't have propane/lp in my neighborhood. The permanent gas or diesel units of this size are much more expensive.

bring on the hurricanes!

[This review was collected as part of a promotion.] Last year we ended up without power for well over a week due to Irma. This hurricane season I am so very thankful out family is covered with for power failure! This is a large generator but very portable and powerful! It's very easy to use and well built! I also can't wait to put it to use on an upcoming camping trip we have planned in the mountains!

Excellent Genset

This particular model has enough available power to run an average 3 bed room house including the furnace and refrigerator. To ensure a no overload condition have refrigerator turned off until furnace or ac kicks in then turn on. Easy to maintain and easy starting.

Great machine - runs everything

I bought this generator to replace a much smaller unit so that I could run the electric range, HVAC, refrigerators/freezer, and water pumps in my home. I installed a 50-amp transfer panel and tested the setup with all the circuits pulling power, and the generator never missed a beat. Future plans are to install a 30-amp transfer panel to power the electric water heater, lights, and outlets. Others have remarked that the unit is too heavy to put the wheel kit on without help. I had no such problem - a hydraulic floor jack would probably help a lot.

Best generator I've ever owned!!

Having had 2 other generators over the last 20 years, this one out-performs all the others. It starts so easy, I really do not need the electric start feature. It has plenty of power to operate the house. We seem to have frequent power losses, so having a back-up is a way of life.

this product, GP17500E, so works

After having our electrical disconnect professionally installed by the power company our Generac GP17500E, Provides power to our 5,800 square foot home without interruption. Just to give you little back ground as to what it operates is as follows: 5 ton heat and AC, well, for water, Three deep freezers, two kitchens, all lighting and electrical, etc... I can't get over how impressed I am how efficient the generator operates. The added bonus is that I can transport the generator and multi task with it as well. I also bought it due the great reviews for their warranty. Knock on wood I have not needed to use but its there. Love my Generac
