Awesome!!!

We finally used our generator (after purchasing for a year) a couple weeks ago when a storm took out our power for 8 hours. We knew the storm was coming so we took our generator out (in a shed on a steep hill) and it was very easy to maneuver and hook up to the generator outlet. My husband has it already set up with the gas and oil so all he did was turn it on and we were set. I used to cringe at thinking of losing power but now it's no biggie...... My Dad even purchased the same one after we told him which one we got and he's had no problems either.

The product is well worth the price I paid.

I have not used the generator in an actual power outage situation but when I ran a test it performed really well. I should have paid the difference and got an electric start but that was my mistake. It's a little loud but no more than expected. I believe it will meet my needs for a back-up during power outages.

Good Basic generator with lots of power

I purchased this generator to run my house in-case of a power outage. It runs the 5 ton ac and everything else no problem. I did put a hard start kit on the ac but I dont think it was needed. We have four dogs so if the power goes out in the summer we have no place to take the dogs this gives us a piece of mind. My 7kw was good for the winter we have gas heating. Cant beat the price!!

Product assembles easily and generator started on first cord pull, but then...

I have rated the quality of this generator only "Fair" (a little below average) because of the two items that follow. The GP3600 generator is easy to assemble and it started on the first pull of the recoil cord. However, I ran into problems when I plugged in an electrical device: There was no power from any of the four 120 VAC, 20 amp, duplex receptacles (note: these receptacles have their own 20 amp circuit breakers). I had to call the store I bought it from and speak to someone who knows the generator and troubleshoot it with him. The problem was that the circuit breaker next to the single, circular 120 VAC, 30 amp receptacle needed to be moved from the "OFF" to the "ON" position. Once I flipped that switch there was power to all outlets. I did not know, and unless I missed it, there was nothing in the manual stating that the 30 Amp breaker controlled power to ALL outlets. There was nothing in the manual's startup procedure about this 30 amp breaker needing to be switched to "ON" so that power would flow to ALL outlets. I would recommend such a basic necessary item be addressed clearly in the manual. One other minor item: The plastic, zip-loc-type bags that the manual and warranty came in were very light grade plastic. I usually store the manuals for all of my power tools in the zip-loc-type bags they come in right in my shop near the tools themselves. So it would be nice if the bags were a little heavier grade plastic.

Great job, but heavy and loud

I have used one of these for a back up generator for my house for 5 years and it does a great job, but I have recently purchased and installed a stand by unit 22kw which is awesome., There are a few things that you need to know before purchasing this unit, it is heavy and I have to use a tractor to haul it from my storage shed to the meter to hook it up, also if it is raining I have to wait until the rain slows down because the connections are open to the elements. the only other thing that pushed me to get a stand by is this unit is really loud. I think if you know these things up front and are ok with them then this unit does a really great job providing constant power when in use.

Does the job

Have had the generator for a few weeks but held off running it until I had a manual transfer switch installed. That happened this week and so the time came to test the switch and the generator. As this was a first run the carb and tank were dry. In went the quart of oil, about a gallon of gas, I pressed the (electric) start button and it fired up without a hitch. I then flipped the well pump, furnace, fridge, a couple of lights and a chest freezer over and no-one in the house even noticed, and the generator wasn't even close to capacity. I hope I never need to use the unit in anger, but I'm happy that if we loose power, we will at least have the basics.

Advice about generator safety that everyone really needs to be aware with.

I have something to explain to everyone about how people use their portable generators during a power outage. A good decision is to have every house have a backup generator installed already which is a home standby generator or a solar panel. Home standby generators are safer because they use natural gas while most portable generators use gasoline which gives off carbon monoxide and not only that. They also injure people if used incorrectly. Many people have died each year when using portable generators due to carbon monoxide poisoning and electrocution. Remember not to run your generator indoors. Running your generator indoors is never safe. That will increase the risk of carbon monoxide poisoning which causes death. Always use your generator outdoors please. Make sure that your generator is 15-20 feet away from house and away from doors, windows, and vents. Some people also run their generator in wet conditions which can electrocute them. Here's an advice about generator safety: please remember that you should never run your generator indoors. Remember that carbon monoxide is an odorless and colorless gas that you cannot see or smell. Carbon monoxide is a silent killer. Keep that in mind. Make sure your generator is 15-20 feet away from your house and away from doors, windows, and vents. Having a carbon monoxide detector is very important against generator safety. Some people also allow children to go near the portable generator which could pose risks. We need to keep an eye on our children making sure that they are not near the portable generator so they won't get electrocuted or burned by the generator which is dangerous. A locking enclosure also keeps kids safe. A generator shed might look like a tempting place to explore, or take cover during a game of hide-and-seek, but a generator is a dangerous piece of equipment that can cause injury. It says on the manual that we should also keep children away at all times from the portable generator to avoid injuries. Generators pose electrical risks. If you need to use your generator during wet weather, you need a generator tent to protect your generator from getting wet. Don't let your generator get wet. Keep your generator dry and before using your generator, please make sure your hands and your generator is dry. Everything that is said on the generator's operating manual should not be ignored. Never smoke cigarettes near the generator. Please keep flammable things away from the generator. Never overload your generator too. Your generator can catch fire. Never ever try to plug a generator cord into a wall outlet to avoid back feeding. Back feeding your generator is dangerous. Always turn on your generator first before plugging in appliances and shut off the appliances before turning your generator off. Use a heavy duty cord for your generator and the cord should not be worn out. All the instructions should be followed carefully. Never refuel your generator while it's running. It can cause fire if fuel spills while your generator is hot. You should turn off your generator and let it cool off before refueling it. This is only a reminder for everyone's safety of using generators. Make sure your generator is properly grounded. This is only a reminder for everyone's safety and for everyone to know about. Thank you hope you stay safe as well.

Changing of the guard

We have been running our old 15KW Generac Guardian Ultra-source gasoline generator for the past decade to power our home during after hurricane power outages. The Generac has always been dependable. ( Be on notice however, if there are huge amounts of ethanol in gasoline, the unit WILL NOT RUN. A thing that may or may not be an issue after a hurricane ). We only run non-ethanol as a standard with fuel treatment, bolster your reserves. With standard maintenance (oil, plugs, filters,battery,,,) and running for 30 minutes+ every month, it has aways been “at the ready”. After 10 years, we are pulling the 15KW from service to rebuild the unit and it will be a backup. The 15KW would run 1 of 2 Central Vac systems, the heavy amp draw well pump, kitchen, home theater, lights, water heater, etc,,. Naturally we can shut subsystems off to conserve fuel. We do have our property in the swamps of Florida, 2 miles from the main road, so we are the last place where propane will be delivered after an event of a hurricane or other crazy events, that is why we chose gasoline. We purchased the new Generac 17500 and was delivered yesterday. At unboxing, we realized that the wheel axle was missing. Fortunately we had our existing 15KW and we had a working axel to maneuver the new 17.5 Generac through the landscaping into position. I thought, “here we go!”. I called Generac Support the next morning and “Bam”! The support rep was an English Speaking American in the States (Chris) and the part is on its way,,, UPS! 15 minutes of may time, done! Wow! It's a bummer that my new purchase was missing a part, but I am surprised at the quick phone pickup with a fix! We will see how the new Generac performs, as it is expected to a active hurricane summer in Florida, The El'Nino weather effect is drifting away again.

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.
