Perfect for RV Owners!

[This review was collected as part of a promotion.] The 3600 is perfect for supplying power to our 32' RV on those trips where electrical hookups are not available. This is also a great addition to any home workshop and a nice item to have for any short or long-term power outage. Here in NC foothills we have a week 2 hurricanes drop 5 or more inches of rain in a short period. We fortunate that our power did not got out but others close by had outages that lasted several days.

Fantastic

[This review was collected as part of a promotion.] Oh wow! What an amazing opportunity to try this. We did use natural gas in this just to try it out and it was incredibly powerful! The unit is noisy but not so much that it would be a disturbance. Our old generator was much louder. This unit is quite compact and easy to move around. It will definitely come in handy when the power goes out! Love that it takes 3 different types of fuel too. Very convenient. Generac is such a trusted brand that lasts too!

Don't they test these things before shipping them?

The generator arrived pretty quick after ordered. I followed the instructions of getting it set up (adding oil, gas, hooking up battery, etc). The generator would not start with the electric start button. I verified the battery was fully charged. It would start manually with the pull cord. I contacted Generac and the closest service facility was 45 minutes away. I dropped it off the day before New Years. I did not receive it back until January 30th. Part of the issue was they could not get the control panel off without damaging the decal that labelled the switches and outlets as it covered the screws. They had to replace the solenoid and repair a wire. They made that repair relatively quick and offered to give it back with the damaged decal. I told them that after spending $1100 for it I would prefer to not have to look at a damaged decal every time I have to use it. The service facility was nice enough to deal with, but they kept the generator outside for awhile. When I got it back it was filthy. In closing, my experience could have been better. But the unit works fine. This could all have been avoided if it was tested before shipping. I also want to note that I bought this because it was made in the US.

Saved by Generac 17,000 Watt generator

Bought the biggest of all, the 17,000 Watt generator some years ago, and never used it until now. Living in Florida, you never know, when you need it, and now with Hurricane Irma, we lost power for several days. Backfeed my house at the panel, and supplied power to all my A/C untis (3 unit total) exterior lighting, etc, since we were the only house among 90 inour neighborhood, with full power, A/C, lights, etc. Unit started right away, and ran for 5 days 24/7. Highly recommendended. Only wish, you could have propane option at the flip of a switch, just in case. All gas stations ran out of fuel, so it would be a nice optional feature.

Nice Generator

This is a great generator as long as you keep the battery fully charged. 1. Keep the generator battery charged. It will not pull start with a dead battery. Use the battery charged that comes with the generator. 2. If you can't keep the generator on the charger install a battery disconnect between the battery cable and the battery. My battery would drain when sitting for 2 weeks or more. The switch solves the problem. I really like the generator..

Love it

I had an old 12,000 or 10,000 watt Generac not sure what year it was that would run my house off transfer switch. It came with the house n was stored under wood box by transfer switch. I bought the house in 1993 and bought a new cheap generator in 2012 to replace the old Generac . I never used the new generator that was a 12,000 watt other than letting it run a bit every 3 months. We had a bad storm in 2020 and I used it everyday for a week till it came apart n the air filter caught on fire plus I could not run a lot of stuff in the house. I just bought the Generac 1500 and used it once on a power outage n it ran whole house. I’m impressed with the quality of the Generac

Easy out of the box assembly.

Easy out of the box assembly. Took about 20 minutes to assemble. Everything you need in the box except the gas. Filled with oil, charged the battery and started right up. Noise level is less than I had expected....that's a good thing. Looking forward to using the unit for home backup.

Quality out of the box, one pull start, only used 30 minutes as first start up trial.

Unit packaging was quality, instructions and assembly of wheels to frame and feet as well as handle was simple. Manual was easy to read, follow for warnings and pre-start up instructions. Unit started on first pull, expected maybe two just to get gas through system. Ran for about half hour to give it a bit of a break-in. Plugged in a few lights and other items to give each circuit a trial. No problems, ran and powered as expected. Not sure what other review stated about eco sense issue, I had no issue as I used the product outside and away from building approx. 4 feet. No issues on my initial trial run and expect this product to do the same after the next big storm hits our area.

Haven't used it yet but looking forward to it

Haven't used it yet but looking forward to it. We live in a hurricane prone area and have dealt with power outages many times over the past 15 years. Most have been for 3 days or more. Although I am not looking forward to the next hurricane, when it does hit I know I will be ready

A BEAST for hurricane season!

[This review was collected as part of a promotion.] We live in Central Florida, and unfortunately having a generator has become a necessity for the months of August-October. We’ve spent too many days post-storm without power, losing both groceries and our minds (from heat). With the hurricanes seemingly getting worse each year, we finally decided it’s time to invest. We jumped on a Generac due to the reliable name brand and reputable quality. Needless to say, the recommendations received from family were good ones because we’re seriously impressed with this thing, so much so that our neighbor saw it delivered and came over to also rave about the Generac brand. One of my favorite features is that this generator can take propane, gasoline, or natural gas. It’s pretty strong and can power appliances, fans, cell phones (imperative), internet, and other small conveniences to keep children occupied. We also plan to invest in a window AC so that we can still have a bit of cold air in at least one room! Just having all of the necessities accessible makes a scary situation just a tad bit more tolerable. As with most generators, this one is HEAVY so be prepared with a plan for moving it prior to getting the wheels on (delivery slip said 275lbs!) We needed three adults to lift and move it, but the wheels definitely help once installed. All parts are heavy-duty, yet easy to operate, but just be aware that this is quite big and quite heavy. That’s understandable with such a powerful unit. If you’re in a hurricane prone area like me, this is one of those purchases that you hope you never need, but will be pleased when you do need it! It’ll definitely make the post-storm recovery just a little bit easier.
