Passed all tests and ready to install. I like the "smart" feature of dropping to idle with the electrical load comes off. I also like the oil cooler and oil filter location. Solid and well thought-out design. So features and construction rate 5 stars. If it lasts as long as the 5kw it replaces (20 years), I'd give it 10 stars.

Generator starts and runs and shuts off randomly. After 15 min. , 22, 5, 45, minutes . Been with out power. Tried at 3 in n the morning after let it cool down to see if there is a overheating but exactly same thing happened as I'm writing the review. My old general 8000 after being in storage for 3 yrs works perfectly fine in my neighborhood house after I let him borrow since I bought this new gen20000 generator. Garbage. Good luck!!!! with the tech support.

That 74dB in the specs is at idle, producing no power. Running, it checks out at 79-80dB at 27ft even at no load. Same as my 20yo Generac but feels louder. But it runs great on propane and produces clean power, a steady 120VAC at 60Hz. Except at idle, where the voltage runs as high as 149V on each leg and Hz up to 75. I'll just make sure to NEVER connect it to any load with it set to idle. Since it is about the only genset of this size that offer clean power AND runs on LPG, I'll live with the flaws.

This is a very well built generator, it looks like it can take on a lot, 1 hour after it was out of the box after adding some fuel and connecting it to a propane tank it started on the first try and was able to go from gasoline to propane and back without any interruption. It is fairly quiet for its size and run very smoothly.

I had to wait about a month for this generator to come back in stock, but it is exactly what I needed. It connects quite easily to my natural gas meter outside of my home. And during testing, I was able to very easily run the entire downstairs power load of my home, which includes a built in freezer and refrigerator, a wine chiller, and separate refrigerator in my garage, plus a gas range and electric oven, dishwasher, a 5-ton AC unit and all the lights!

Bought this generator to power the house. Having two means of fuel is great. Much quieter than my smaller generator. Like that it has a replaceble oil filter. Although this unit is heavy. I was surprised how easy it is to move around. Well built and quality components. Shipping container was robust, comes on custom pallet - no concerns about damage in transit. Overall, I am pleased with this generator.

Purchased a few weeks ago and delivered in perfect condition by FedEx Freight this last week. Like the quality of parts/assembly and extra features in the design. Started first time on propane. Have not used (yet) with gas. Modified the gas dual carburators with new altitude kit #140574, 2 ea. "C" jets for 5k-6k ft. Not the easiest job, but ok with my knowledge (no instructions with kit). Note: Current manual lists wrong kit, not for this larger 713cc engine. Call into Westinghouse to let me know correct high altitude propane kit. Also wrong LP kit listed online. Overall very happy with purchase price and quality. Hopefull documenation for this newer, larger generator will improve soon.

Provides more than enough power for my rv. Is a bit finicky about starting. Only had for 6 weeks and had problems w the clicker and now I have to run a smaller generator to charge the battery so it will start. but I’m still getting start issues. now it says needs maintenance. Cleaned the spark arrestor and plug. Getting co2 warnings when under a roof against a wall. Not enclosed.

I bought this for backup power due to two recent power outages. Murphy's Law, power hasn't been out since. After assembly and filling with oil and gas, the generator started on the 1st try. Can't say that I am eager for another power outage, but I will be ready for it when it comes.

This unit was purchased as a backup generator since we live in a hurricane prone area. I am happy with the construction, layout, and engineering. I have tested the unit with natural gas under light load and encountered no problems. My only complaint (and the reason for not giving 5 stars) is that the package was missing a dedicated hose for natural gas operation as per the packing list. I adapted the included propane hose by removing it from the propane pressure regulator.
