Impressive machine

This thing is a beast. I connected to a manual transfer switch with current monitors to watch and balance the connected load. I have run a few tests but haven't had a true outage yet to put it to the test. V-twin 992cc engine runs great and starts easily with the electric start. I did connect a battery tender to trickle charge/monitor the battery. Other than that it comes with everything including a spare tune up kit.

I recommend this product

The generator is easy to use and to move around. The portability makes it useful in a number of different situations. The generator is a bit noisier than I would like, however, the convenience and ease of use out weighs this distraction. Should we experience another hurricane, we will be quite comfortable and safe. We plan to have this wired into our system so that our whole house will have power in the event of an extended outage.

Saved our Christmas!

We were in the Michigan Ice Storm of December 22, 2013. Our yard looked like a war zone when it was over, trees pulled our power lines to the ground. I bought this generator on Monday the 23rd and got it running and hooked up to my fridge, freezer and furnace and several lights in no time at all, very easy to set up and run. It ran flawlessly for four whole days and nights, it would run 12-14 hours on a tank of gas. So glad I bought this, we enjoyed our Christmas with family, even though we did not have power to our house. Buy this generator, it will run your whole house!

I cant give a review since I have not been able to check the equipment.

Out of failure. As soon as I pour gas into the gas tank it start to run out onto the battery, the leak is next to the shut off valve. I immediately customer service @ 888 436 3722 to report the issue the gas tank was leaking above the battery. rep wanted to know if the tank was crack I told her I did not know. The rep then activate the extended warranty then give me two Authorized Generac Service Dealers. I call the service dealer who instructed me to contact the Merchant i purchased the Generator from, since it is a out of box failure. Photo and video attached.

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.
