real nice generator

I bought this generator at the suggestion of my contractor. He knows what I needed. The delivery was simple. Though you will need four men to unload if you don’t have a lift. It was delivered in good shape. It was easy to put together, though the print could be larger (need a magnifying glass). It took some figuring out. It started up super easy. Haven’t had to use it yet, but am confident it will do the job.

Good product but part issue needs to be corrected

Bought my Cosense GP 6500 in October 2018 after Hurrican Michael knocked out our power for 2 weeks. Fast forward 2020, I went to start the generator to let it a run a few mins. Did the pre start steps, opened the fuel valve etc...and as soon as I started pulling on the crank, fuel began to flow out of the bottom and sides of the carburetor. Did some research and find it is a common issue with Generac generators...the culptlrit appears to be the float and the needle valve pin. So now I have to decide to try and fix it myself or take it to someone. Very frustrating especially with this being a common part issue....

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.

Great performance, easy to use

Bought GP15000E after extensive research. Because of demand, it took almost four weeks to receive it and Generac transfer switch. Worth the wait. Both were reasonably easy to set up. I store the generator inside garage, but suggestions for shelter when it is being used outside would be appreciated. There are some slight differences in operating instructions between the generator and transfer switch manuals.

Overall Good Generator for the Price

I purchaed the 7500E about 9 Months ago, overall the Generator has been great and very reliable. I only had two issues, the first issue happened 20 hours after initial startup. When the engine wouldn't start due to a valve problem. (Repaired under warranty). The second problem was a build up of Carbon which prevented the engine from rotating. The second problem occured after 959 hours and was not covered under warranty. It cost be a little over $110.00 to repair. Other then those two issues the Generator has been great.

Great Generator, But

I bought this unit for backup power 9 months ago. I run it 30 minutes every month. The last time I started it, it leaked a gallon of gas around the generator. Had I not checked after 5 minutes running, I am sure my building and surrounding buildings would have gone up in a huge fire. Needless to say, I returned the unit for a refund. I can't recommend this without knowing what the problem with the generator is! Never, never, another gasoline generator.

A workhorse

I bought THIS generator because of the past experience with the brand, AND because this unit had a larger engine than most of the similarly sized generators. The typical 15kw genset has an 18 to 22 horsepower engine. This model has a 30hp engine!! That extra horsepower means greater power margin for starting loads like HVAC compressors. I calculated that I needed 10kw, and this units 22kw starting capacity exceeded that substantially... But in my experience I need more than the minimum because if the hvac computer crashes because of voltage drop, then starting will fail. You mush have excess power during the starting of the compressor to keep the computers happy. So I picked carefully, and while this one has much more power than I require, the price point and performance thresholds were met by *only* this generator. So I did my first test running the whole house, and this generator handled the load with few problems, but the power was very noisy, very high harmonic distortion. Some things in the house ran fine, but things powered on transformers did not like the power. The home thermostat was inoperable, the computer in the dishwasher crashed, several of the UPS systems did not like the power and complained, and my smart LED lights were very unhappy. Sensitive loads did not like this generator at all... But once I got the thermostat bypassed, the HVAC compressor seemed to run fairly well, though the compressor was noisier than normal. So to meet my needs I decided to buy the largest inverter generator that I could fine to run the house and electronics, and the Generac GP15000E is dedicated to the HVAC compressor *only*. The HVAC blower and electronics run on the inverter generator where they are fed a true sine wave. I didn't set out to buy this much excess capacity, but I still paid less than I would have if I had bought a similarly sized whole home generator, and I have a reconfigurable power plant now so I can handle any need.

Ran for 4 days straight

This seems to be a good generator is provided backup power for me for 4 days straight. The only thing I wish the generator had was a percentage used of power as other generators offer that feature. The only feature offered on this is the hour meter which is very good for maintenance

solid

heavy and durable. runs forever i would like to see someone try to start this with the recoil rope, though. if someone can actually do it they should probably be in the olympics or barnum and bailey's circus i tried it on fresh fuel and a hot engine ( right after shutting it down ), and there was NO CHANCE of this thing ever starting with the pull cord. keep the battery charged

Won’t even run a freezer or frig

Just bought this product from Lowe’s today 10/27/2019 after pg&e shut off our power. Got it all hooked up and plugged in a small freezer and a frig. After ten minutes the gfi keeps tripping. Tried all 120v 20amp outlets and even the 240v and 30 amp the power keeps shutting off and the generator keeps running. I will be returning this product, sad to say. It looks like a great generator but failed me.
