Excellent value for the money

This new unit is replacing a 9 KW portable unit that ran my whole house except for the Hot Tub and central AC. The new Generac runs the whole house with power left over. I just wish that it would come with a voltmeter. It was easy to assemble and runs great.

Generator

[This review was collected as part of a promotion.] I'm super happy with this generator. It's very easy portability wise to move around if needed as it's on wheels. Maintenance is easy, so that's a plus. When the power goes out, this will help light up the whole house. Noise level is hardly none.

Easy assembly & powered up quickly

This generator weighs over 200# but with the wheels on, it is easy to move around. Assembly was easy and I had it running in no time. Took my time, made sure all connections were secure and it fired right up. Pluged in a light and it worked just fine. Haven't had to use for emergency power yet, but now I am ready.

Big enough for the job.

Shaky start with this machine. Dead battery out of the box and loose contacts in the outlets. Wheels adequate for concrete, but wish they were larger and fatter for moving through gravel. Starts easily. Noise is at 73 DB as stated. Factory Service center took care of the battery problem, but wasn't concerned about loose contacts in outlets. Duh. Sometimes no juice comes out of the 110v side. Have to fiddle with the plugs to make contact. Had a short power failure after purchasing and debugging the generator. Decided to wait for daylight before hooking up generator, but by then power was back on. Because of the garage door design, I will make a shed for the generator's outside storage next to the 220V receptacle. Secondary purpose for the generator is to power the community well in our plat, if needed; hence the need for wider tires when moving the generator through the gravel to the pump house. I think the generator is worth the cost, but am sorry the Factory quality control was sloppy. I wish the factory would actually run the machine and completely test it prior to shipping. A little odor in the gas tank at the store is a small price to pay for enhanced reliability. Nice to have features: a battery feedback circuit, and an output meter advising how much wattage is being drawn by the system being supported by the generator. Best advice I can offer to a buyer is buy the generator in June or July. I didn't get around to purchasing my generator until winter, and there was no selection available in two Counties. This machine was literally the only generator of this class available. I went looking for an 11,000 watt machine and had to settle for this 8,000 watt machine. I think it will run the pumphouse. Maybe I'll never have to find out.

I was very pleased with this product

The unpacking and assembly were well described and easy to complete with minimal mechanical skills. The engine started right up and power was immediately produced. I let the unit run for a few minutes and then checked the oil level and examined the unit for any leaks or other obvious issues but none were found. I would recommend this product to anyone in need of a large portable generator for emergency or other short term uses.

Great product

We used this generator less than 50- hours. When we needed it again summer of 2020 we discovered the generator burned!!! Very DISAPPOINTED We had to use an older 10- year old Briggs and Stratton that started up right away. We are currently waiting on new generator to be ordered and delivered , due to Covid reasons it’s taken this long. We pray once a new generator is installed it will work great for us for years to come.

Awesome generator

Bought this for backup when the power is out. Electrician installed an interlock switch so as not to backfeed power to the grid. Now i have what i need when the power is out !! Love the electric start. Also like that the choke is integrated into the start switch. Mine was a display model and was missing the cord for charging the battery. Called customer service and they promptly sent one via mail at no charge. I have owned other brands and generac is by far the best.

This is a tentative review

Out of the box looks great, easy setup and starts easily 1x per month for testing ( starting) only). Today I needed it most with an ice storm and power outage. Fired up and ran great, but produced no electricity from the outlets. I took it into the service center, but still had a dark cold house. I will update with my service and warranty experience.

No power :(

Well, I bought this a couple years ago to use when we go camping. I used it once and had no issues. Today I got it out to power my furnace in the house. None of the outlets have power. I checked the breakers and no luck. I tried the GFCI, but it won’t trip because of no power.
