Solid Generator

4 days ago
My generator has worked flawlessly since I purchased it. Unfortunately I have been unable to get it to work as I had intended, which is to run my pool circulation pump during winter power outages. I have verified through multiple electrical experts that my connection from the generator to the pool equipment is correct. My next step is to adjust the Hertz output down to 60 from the 62 it is currently producing. Any direction you can provide me to make that adjustment would be sincerely appreciated.

Yes, I recommend this product.

Didn't even get a chance to use it/ it failed.

5 days ago
I bought this new generator new in the box for our deer camp. We unboxed it and added the oil and clean gasoline and started it. It was gushing gas out of the carb so we had to shut it down. When we called Menards to bring it back for an exchange they said that they don't take them back and we had to bring it to a certified repair shop that was 75 miles away from our camp. Needless to say, we didn't have a generator for deer season because the repair shop was booked. When I picked it up the owner said that the carb was full of gunk and that he couldn't even charge Generac for the repair because it was a fuel issue. how could that be possible when it was brand new out of the box? I am very disappointed that we have a generator that could be a lemon and the repair shop didn't get paid!

No, I do not recommend this product.

Overall, very good quality and features.

Just bought this a month ago and haven't had the need to use it yet. But I did have to assemble the handle, wheels, add oil and gas and start it. My review is solely based on that. The wheels were relatively easy to assemble, keeping in mind that the machine is heavy and you will need to lift it on blocks, or use a helper. They give you a perfectly shaped funnel to add the oil. Don't lose it. The handles are easy to install and conveniently fold down when not in use. They make it very easy to roll around on the two wheels. You also need to connect the battery wires, which they don't explain very well. Remember Red is positive, Black is negative. My only gripe is with the gas tank cover, though. It is very large, and very low profile, and it is in a sunken area of the tank. It is very difficult to get a grip on it to remove as it is also very tight. Why did they make it like this? I've never had any machine have a cap like this. It does have a convenient fuel level bubble. The gas tank is 8 gallons, not just 5 like my older model. It is rated at a continues 8KW, although the 240V 4-prong cable that connects to the breaker panel is only capable of carrying 7.2KW. You need to use the 2 120V outlets to get a total of 8KW. Keep in mind that the battery does not get recharged by running the engine. You have to use the included wall charger. Although, a single start is not going to use much power, so you don't need to worry too much about always keeping the wall charger connected. But definitely charge it fully when it is new. It has picture-based instructions on the frame. But they aren't very useful as they pictures are too small to figure out what they are saying. Remember to turn the fuel shutoff to ON and set the choke to ON when starting it.

Yes, I recommend this product.
