I purchased a 13kw Trifuel Generator last year after hurricane Beryl left us without power. I've since changed my backup power plans and I no longer need this generator. This unit can run on natural gas, propane, or gasoline. I have never tried to run the unit. No fuel or oil has been put in. It is essentially brand new. I have an industrial quality 50ft 1" natural gas hose that I am selling with it. Included are the fittings and quick connects needed to hook the hose up to your home's natural gas. The generator is listed for $1700 online. The 50ft hose w/ quick connects cost $500. I'm also including the miscellaneous fittings I picked up from Lowes to connect the hose to the generator. All that is missing from this setup is the power cord to connect the generator to the breaker box. Asking $2000. Located in Houston.


Price drop to $2000 for everything. $1600 for generator only.

How much of a "normal" house will that run?

It depends on what you want to run. I was planning to use this as a whole home generator and run my 3 ton AC unit, refrigerator, and lights. There's a generator thread on the Houston board where several people have run similar setups with success.

Max on a 50amp plug is 12kw so this is esssentially as much juice as you can put into a house through a simple interlock kit. Will run a full house including a 3-ton central a/c.

Hose many hours on it?

Zero hours. Its unused.

Yes and no.

It's closer to 11,600W on a 50amp if I remember correctly. But you're only getting that on gasoline with this (which most people try to avoid running these on because of the corrosiveness of modern fuel). On NG, it's only going to provide 75%ish of that constantly.

Now that doesn't mean it won't run someone's entire house. But the only person that will know that is the person who runs the calcs on what they want to run.

And may need a soft start on that AC unit.

I had solar installed a couple of months ago and along with that came an app where I can monitor the load needed for my house at any given time. I've got two A/C units, each one is about 3000 watts. My "baseline" usage (stuff that is always on) is 1500 watts, included in that baseline I've got a garage fridge/freezer, a standard kitchen fridge/freezer, and 21 cubic foot deep freezer, the septic tank stuff, and a couple of ceiling fans that never turn off. My water heater is gas. When people are home that baseline changes to around 2000 watts with lights and TVs. So with both A/Cs on and people home I'm using roughly 8000 watts. Then you've got stuff like a microwave, that's 1000 watts, my Keurig is around 1000 watts. My washing machine is about 750 watts and my dishwasher is about 600 watts. My dryer and stove are both gas so they have minimal usage. The only time I go over 10,000 is when I'm using my large air compressor in the shop, people are home, and both A/Cs are on.

Not sure about winter months yet, my assumption is usage will about the same, my furnaces are gas.

All good info. But that's running watts, not peak.

Those fridge / freezers, ACs, etc. may draw twice as much as start up and they cycle off and on all day.

Doesn't mean you need the max power of all combined. Plenty of things can be powered off or cycled opposite the others here and there during a power outage.

My house for example is a 1970ish 2,450sq/ft one story in an older neighborhood. Soft start on the AC. A portable generator almost exactly like this couldn't power everything at once as it cycled on and off randomly. I had to limit the 3 fridge / freezers and other things if I wanted to run the AC. Which worked, but got annoying. Especially if the wife was ever home alone. This generator might not have a single hiccup with a smaller house or less large appliances. Only way to know is to know your actual usage (peak and normal run).

I now have a larger portable that puts in the max 11,600W on NG and it runs everything all at once, no issue.

Good luck with the sale OP. There's someone this will be a great fit for.

I appreciate the discussion. For anyone doing load calcs at home please note that this unit is rated for 13kw peak usage when using gasoline as fuel. When running on natural gas, the unit only runs at 10kw peak and 8.5kw continuous. This is enough to start and run a smaller central AC system provided there is a soft start on the compressor. This unit will probably not start your AC while you're running your electric oven and coffee maker and dryer. I bought this unit with the expectation that it would power the essentials (AC, fridge, lights) in my home during the next disaster.

Price drop. $2000.

I've got a very similar generator. I had to use it once to run my whole house during an outage. It would not run my AC. But everything else was great - lights, fridges, freezer, internet, tv etc.

If you want to be prepared but not spend tons of money on a generac, I would recommend buying something like this generator and buy an AC window unit or two (it will run those easily). An electician can install a whole home switch to plug this in to run your house.

I think this is a good deal.

You may want to edit the OP to include this info. Some people won't scroll to the bottom to see this.

I'd post this in the Facebook group "Generators: portable generators to power entire house" as it seems like most folks are in Houston.

OP, I know you have substantial cost in this, but it bears pointing out that the generator itself is on sale for $1700 on Amazon right now.

I'm aware it's on sale on Amazon. That's why I provided the link in the OP. There's more here than just the generator. This identical setup would cost about $2500 if purchased today.

I have this same generator. On gasoline it ran my downstairs 4 ton AC unit (no soft start), fridge, freezer and all lights and small appliances.

I got a plumber since then to get the NG setup for it and I need to get a soft start.

Overall it is a good generator with the expectations that it will get you by without power but won't run everything like a whole home system.

I have the dual fuel version and used it during Hurricane Beryl for several days. On propane it's just enough to get our 5 ton AC unit going, plus several other circuits including two full size refrigerators and a chest freezer. However, it did trip the breaker a few times when it was having to work hard. So I switched to gasoline. On gas it easily runs the AC, refrigerators, freezer, stove, microwave. Really, anything we need.

During the outage I hesitated using gas b/c I didn't want to deal with the shutdown and storage steps afterward. But it's very easy. Run it empty, clean out the carburetor cup.
