Great video of comparing the 2 models with a few minor corrections, the 11500TFC has a 550 cc motor, not 533, the 50 amp plug will output the total 11500 watts of the generator without using any of the other outlets and the big difference is cost, the Wgen 12000DF is almost twice the cost. I acquired my 11500TFC a week before Beryl hit here in Houston, ran it continuously for approx. 36 hours ( we were extremely fortunate in regaining power so quickly). Extremely pleased with its performance.
One thing to consider, is that a 50A breaker will not trip immediately if you pass beyond that current level. You will be able to reach a higher current for a short time before the breaker does trip. The higher the current beyond the breaker value, the shorter the time it will take to trip. A different example related to this, is that an AC Compressor/Condenser unit which may have 100 amps of inrush current does not trip the ~35 or 40 amp breaker that it is tied in to. The 50A plug will absolutely allow more current than that, as will your cables for a short time (peak / inrush), which is why they are protected properly sized breakers. Short spikes beyond that are going to be handled, but you are correct in that to utilize full continuous power from the larger unit (Wgen14500tfc), you will need to apply loads to the additional plugs since it can produce beyond 50A continuous.
Maybe the most important consideration is the THD level. The 11500tfc has a THD below 5% while the 12000DF THD level is much higher. Additionally, the Trifuel feature on the 11500 unit provides that much more flexibility - I’d run NG or propane only until getting that becomes a problem then run non-ethanol gas. My 11500tfc unit runs like a champ on NG (using 3/4” NG hose). Converting the unit to a floating neutral was simple and the ‘how to do it’ was in the instruction manual (remove one green/yellow stripe wire) - very simple. Also wired up a male ground plug so I could switch to a bonded ground if needed - it’s wire tied to the frame for quick access. In my case, In my case I have a well pump, sewer grinder, gas heater and water heater, gas cook top and other electric appliances. This unit runs it all with a load demand of about 9kw if everything was running. Great unit - The Wgen 11500TFC😊
Thank you! I was wondering why their was such a large size difference, and the Twin Cylinder makes all the difference! First comparison video i've seen, so Bravo!
Thanks for watching. Hard to tell the true size on website pictures. Seeing on video side by side, you get better clarity of the engine and stator are a lot bigger on the WGEN 12000DF.
The WGEN12000DF is a totally different model generator than the Wgen14500DF. In the Westinghouse website they're listed as two different models. They're almost the same besides the power output difference. The Wgen12000 puts out 12,000 continuous / watts and the Wgen14500 puts out 14,500 continuous watts. And they’re listed at the same price. If you take a closer look at both generators front panel, you'll see the difference. The Model generator you got there only puts 12,000 continuous running amps and a maximum of 15,000 peak amps. It doesn’t puts out 14,500. I have all these from the Westinghouse Website
Just purchased the 14500 for the house. I had the 11500 but I felt it struggled a bit, even with a soft start on 5ton. I know others have not experienced it but, I did and not sure why.
All A/C's are not the same, and unfortunately, the Soft Start effectiveness can vary. Mine reduced the LRA to 25 amps from the first start at 71, for 60% reduction. Others report 40%. The newest A/CS also may come with Thermal Expansion Valves (TXV) which, from my limited understanding is less influenced by the Soft Start due to their mechanics vs a piston driven compressor. a 5 Ton A/C is a very large unit!
@@wesr228 I think, from what I read, If yours has what is called a non-bleed txv valve. Then soft start either doesn't work or won't work as well(needs like a different capacitor(bigger) for the soft start), with that said, I am not sure with the NEW Micro Air FLEX, (2-6 tons one size fits all), if that has been corrected.
@@gilbosdiy I installed the Micro air easy start Flex a short time ago on my 14yr old 5 ton carrier unit. The specs on my AC unit were 117 LRA, after install of the Flex 23.9a according to the app.
Would it be possible for you to make a vid on floating the neutral on that 12000DF? I've got one coming & want to get that done. BTW, what was your choice between the two?! 😃
The WGen14500TFc is trifuel (thus the TFc). That makes the decision a little harder.If I can keep this outside, run a line inside and run a cabinet size table saw (and other things) on it, I'll probably get the WGEN 11500TFc because of the price differential. It's cheaper than an electrician. I'd have to move it around with my tractor's forks. Any thoughts? This was a great comparison, thanks. I was trying to decide between the two and I came upon your video. Great job.
Hey thanks for watching. Glad this help. This one of those questions, that only you can answer. Best to take a quick count of the TOTAL wattage you might have running at the same time. That will be the best way to determine which generator. If I had to pick, since it sounds like you have some property/acreage. I'd go with the WGEN 14500 TFc. Hope this helps, if you have anymore questions, just ask, and I'll try and help. Don't forget to hit the like and subscribe button.
seems like the NG and propane models both use the same regulator... wonder if you could hook up NG to the dual fuel one and it would still work? Why they don't make it tri fuel i don't understand
Yes good choice, it's a really, really good mid range open frame generator for the price. That's why I think this one will be one of Westinghouse's best seller. Don't get me wrong the 12000DF is a beast and doesn't even flinch, when a load is put on it. Yes the Wgen 11500 TFc is way less than the Wgen 14500 TFc.
@@gilbosdiy the 11500 started my 5 ton with ease, using the Micro Air Easy Start. Also, I was quite happy with the sound of it. It was a much more pleasant tone and a bit quieter than my Briggs Storm Responder 6250. Just over all ran much smoother than the Briggs.
My neighbor was using one of those Briggs units, and that thing was ear splitting when we were working close to it. My Champion 6kw was loud but easier on the ears. I'm eager to see how my 11500tfc sounds when it arrives. @@prezzzrock
I think the rebadge is going to run $800 more that the 12000DF. I have a ton of propane might just do no CO sensor and 12000DF and get the parts for the NG conversion if the need ever came up. My goal is 30 days no power could probably go 15 currently.
I almost got the 14500 but last minute got the 11500. I've debated on upgrading to the 14500 but i'm not sure yet. I didn't like the load it seen running my AC and hot water at same time. I ended up alternating them for shower during last storm. I am surprised about the wgen12000 being same model as the wgen14500. Do you have any information as to if there are differences or is it just a new rating with the tri fuel model?
I think they somehow realized the WGEN 12000DF was capable of more than stated. Or they knew all along, and held back to sell more. So they rebadged it. I highly doubt they upgraded the stator/ alternator. If they did put a bigger stator/alternator the weight would have be higher. In fact the dry unit weight is 4lb light on the 14500TFc vs 12000DF, go figure. Thanks for watching.
It does run on natural gas. Here's the playlist on how I converted to run on natural gas. th-cam.com/play/PLO-Dg9zks7ZTeT6XwslVtwZgWNvOtW43Y.html&si=hvXId4vIArreXX1F Westinghhouse did convert to run on natural gas now as well, they rebranded to WGEN 14500 TFC..
@@gilbosdiy hi Gilbo. all of the westinghouse generators are currently out of stock. however i have found a place that has the old 12000/15000 DF in stock, the one that you converted to natural gas. should I buy this one and convert it? or should I wait for the other ones to come in stock? I need to run 5 ton AC that has easy start on it. Thanks
Yes, I just replaced my battery in May 2024. I just got it on Amazon. It's the Mighty Max Battery 12V 22AH GEL Battery for BMW K1200LT K1200RS 51913 I paid like $59 for it. Hope this helps.
I really wonder if the WGEN12000/15000 and WGEN 14500/18000 are the same unit. Both use the 713cc engine and I consistently get 55 Amp @240V from mine. No modifications. Make sure to use a heavy cable. The 15’ 6/3 cable I use gets warm after a few hours feeding the house.
Does anyone know if some of the new models that have dual 50 amp outlets. Can you run both to your main panel at the same time. If not they don’t seem to have a use for a whole house generator.

The 11500 is listed as being less than 5% I would be VERY interested to see a measurement on both.

no brainer - the natural gas option is huge bonus. Plus that 11500 is much smaller. Same output essentially
Yea, I feel natural gas with a high enough output (9500 watts running min.) on a portable is the way to go. No need to chase fuel.
Dude - move your finger.... Geez
