Great so far!

I had been looking for a powerful generator for a while. We had lost power for a day and a half not too long ago due to a tornado. After that a sub station close to the house had to be shut down due to it causing a grass fire. My wife and I were ready to get a generator. I had looked for a while and the reviews on this one were great. I'll try to let you all know the more I use it.. hopefully I'll never have to!

Powerful and Reliable Generator

I am born and raised in Florida and have been through countless hurricanes. Power can be down for weeks and even months. I needed something powerful and reliable, and so far this generator fits the bill. Have not tested it for an extended period of time but this thing crank right up first try. The remote start is an appreciated bonus. This generator gives me the ability to run my entire house with a/c, minus the drier and oven. As a mechanic, I cannot emphasize enough how important the break-in process is. It requires several oil changes with unloaded and loaded power cycles. There is little to no information about this process in the manual and the choke settings explained in the instructions is wrong, but common sense should prevail as it is an obvious typo. I absolutely love the tri fuel capabilities. When the power is out you will not be able to refuel if you run out. Having the ability to use propane when that happens is a game changer. Get you several 14 gallon fuel totes, fuel stabilizer, a cover for the generator and properly rated extension cords if you're not hooked to your panel. Obviously keep the generator as far away from windows and doors as possible. All together I rest easy knowing my family is prepared if and when another storm hits. I have owned Westinghouse in the past that was unfortunately stolen, but I find this brand to be of high quality and dependable. I definitely recommend this generator.

Power outage peace of mind

I bought this generator after a recent widespread 3-day power outage. We have 2 freezers and scrambled to find someone who could help us store all the frozen food. An electrician highly recommended this unit and did the installation for us. We like the units many features such as remote start, quiet operation and versatility of the tri fuel system as well as its ability to handle most of our needs.

Great so far

I bought the WGen14500TFc last year. It runs like a champ and it easily powers my entire home except for central heat/air. I don't know that it wouldn't also handle the HVAC but I may consider adding a soft start before I try. It is a little noisy but I knew that going in and it is a fine tradeoff to have this level of backup power at a good price point. Right now my only recommendation to improve the generator would be for it to come with a magnetic oil drain plug.

A great generator - a serious piece of hardware

I just purchased this for home backup and shop use and have only run it a little. My plan is to connect it to the house natural gas and use that as much as possible. This thing will easily run everything in the house, even though it has to be derated due to the altitude. It seems very well built and uses quality components. I like the paint finish too, nicely done. It is very convenient that they included the oil and the battery with the unit, which makes it possible to complete the setup and get it running as soon as it arrives.

This Generator Far Exceeded My Expectations!

I live in a luxury RV in the FL Panhandle and I wanted a generator that could handle 3 air conditioners, washer/dryer, refrigerator, and everything else in the event of a power outage. The dual fuel provides an excellent option in case gasoline becomes scarce. We thing we are now prepared for any electrical outage. Excellent product! Thank you!

Great Product!

Product was quickly delivered and packed very well. Haven't had long enough to test out so that's why I give the 4 stars and not 5. I did run for 1 hour unloaded to start the break in period and took a few remote starts to allow fuel to reach the system and then generator did run smoothly. So far so good. Time will tell!

Lots of power

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.

WGEN14500/18000, initial review

Only 3 stars at present until Westinghouse responds. And, no recommendation until Westinghouse responds. Assembly instruction are clear, and assembly and initial setup went pretty well, but there are a couple of issues. Once the wheels are on, the battery cannot be removed to connect the cables, so off came the wheel. Also, the dip stick is awkward to use because on a instruction plate above the stick's grip. Still, minor issues. I put in 5 gallons of 87 octane unleaded gas (<10% alcohol). The generator started immediately, with no issues. I let is run for an hour without any load connected. I do have a concern about the engine and generator stability. The engine RPM had a slight instability which sounded like a very, very, slight misfire, but no popping from the exhaust. Voltage and Frequency shown on the set's display was 240 +/- 1V, and 59.6 - 59.9 HZ. I did not connect it to my house, choosing to wait until the following day. Following day: The set powered up immediately, which was nice, but I noticed that the display was now showing an unstable frequency 59.3 - 59.8 HZ (why lower than yesterday?). Voltage was 240/241 V.. Stopped and restarted the set, but no difference. I had intended connecting to the house though the 50A inlet and interlock, but, before doing so, I decided to first look at the voltage waveform with an oscilloscope and meter. I was surprised to see that the intended sine wave looked more like a triangular wave. I don't know if this is the correct output from the Westinghouse generators, so I will look forward to Westinghouse's response. Attached are two video's showing the generators output vs my utility supply. For a valid comparison, the same test setup was used. Couldn't attach the videos because it seems that Westinghouse only accepts YouTube videos, so all I can show is a photo of the WGEN's output waveform.

Not worth the money

My unit ran great the first few times I used it. After the 3-4 time I went to use it, it wouldn't start and if it did only stayed running for a few mins. Took it to factory authorized repair that kept getting same bad part several times. After 2 1/2 months they are finally replacing the unit, I'll never buy another of these.
