Has failed with only 37hrs

Unit purchased 4.5 yrs ago. Ran great till used this yr. Followed all required maintenance and unit stopped during power outage. Shop Arlo has replaces magnetos and now telling me needs new carb. $728 in repairs and still don't know if will run. I can not recommend this $3000+ generator when i am spending 30% cost of unit after only 37hrs. This is ridiculous and Generac has told Arco they won't do anything to help. Very disappointing for a company to treat customers this way.

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.

Purchased in 2014

I live in North Georgia, we have ice storms and snow storms and tornadoes, even tropical storms that knock out our power from time to time. My house was prewired for a generator and has a transfer box. This unit was pretty much a plug and play situation. It easily runs the heart of the house more then adequately. For the last 3 years we have had to use it for every year for anywhere from 4_days to 2 weeks and we ran it 24/7. Other then changing the oil and replacing the starter battery, its been maintenance free. I heartily recommend this unit to anyone that needs a generator.

This product is...."The Beast"!

Have owned a 7,000 exl by Generac for years and never a single problem. Made the decision to purchase this GP17,500 watt beast. Very impressed with the quality of this unit. Fired up without the choke on first start out of the box! Have only ran for an hour doing a break in, so haven't put a load on it yet, but I can tell the Beast is ready! Thanks for a well made product!

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.

Works well, enough power for the whole house

Except for hurricane Sandy, over the last 30 + years we had never lost our power for more than a couple hours at a time. And even those weren’t frequent. Then this past summer we had a Nor’ Easter with 60-70 MPH winds that lasted for a full day. We lost our power and did not get it back for almost 8 days because of the extensive damage causing slow repairs. I did not want to go through that again especially in the winter when not having heat is a safety issue. Bought this generator because it had enough power to run the furnace or central air plus the the two refrigerators and freezer we have. Had an electrician do the wiring to do the whole and not run extension cords. Have used it once since I bought it when we lost our power during a snow storm with high winds. The electronic start worked great and we had power enough to run everything. for the six hours till power was restored. Found the generator easy to start and run. Is small enough to store pretty easily in my garage. On the minus side it would be nice if it was quieter. And this is knit picking but it’s not easy to register and the serial number is hard to find. Added gas stabilizer as there is a decent amount of gas left in the tank and I intend to run it once a month till the gas is used up. Overall I am very happy with the purchase and is well worth the price for the peace of mind and convenience for the infrequent times of power loss.

Unreliable Generator

Owned it 2 years. Refused to start on one of regular start up dates. Took to small engine repair. He got it started after changing spark plugs. Got it home and battery was dead. Refuses to start. Can't count on it when we have a power outage. Waste of money. Now having to look at getting a Honda.

Great Generator

Purchased the gp6500 after a lot of research. It offered the best power for the price. We only had to use it for a little over 1 hour for the first 7 months we owned it. We have been faithful in starting it about every other week or so and ran it with a load for about 20 minutes. We have kept the tank full of gas treated with stabilizer. Well sure enough we lost power this week do to freak March snowstorm. Started on the second pull. It ran over the course of three days for 29 hours. Worked flawlessly. Really a lifesaver, especially with three kids and the wife. Ran 3/4 of the entire house including a well pump, two refrigerators and a deep freezer. We have a Woodstove in the basement so no need for it to run a heat source. Bottom line... Awesome product, great value and so far seems durable. If you're debating this generator, go for it!!!!

Generac GP18000EFI

The generator is being used to charge batteries and run a small cottage at the same time. No complaints about weight and size as it's expected. It fired right up and started going to work. The only problem we have encountered is the 30AMP breaker keeps tripping if we run small window air conditioners (5AMP) or anything at 1,500 watts=12.5AMPs for a brief 5 min. The offgrid includes four banks of 48V AGM batteries. We set the Magnum inverter down to 80% and AMPs down to 38. This seems to be helping but we can't put a larger load on. So we installing a 50AMP plug on the house with a cut off and bipass, essentially we will be running the 30AMP plug to charge the batteries and the 50AMP to run the house. Typical charge on those batteries is around 4 hours. If you plug an appliance at 12.5 AMPs direct to the generator - there's no difference in load sound. As a building contractor we designed our own off grid system and will be writing a book with as much detail as possible.
