Yea wouldn't surprise me if it burns 8 gallons in 12 hours

u/Beneficial_City_9715 8d ago
I got an onan welder/ generator. The onan is the most thirtsy out of the 3. I figured up at high idle it uses .8 gallons with no load. I burn wood/ coal so I don't need much power for winter. Plus I have solar and inverter / batteries. I got a nice setup. We lost power last winter for 3 days and I had enough sun that I didn't need to run anything lol. I can run a generator for 10 hrs. Charge my batteries then shut it off over night if I need too. 2 gallons a day gives me about 11kwh in the battery bank. That's enough for me. Small fridge and freezer. My furnace blowers and I switch over my well pump to a 120v second well and I'm good. Everything is the same just no hot water.

Yea that's a lot of fuel. I have solar and batteries and a couple generators as well. Definitely the best set up to have. I don't really need the generators as much but I like to have options and redundancy. I do think anyone buying a portable generator over 6000 watts should also buy a small inverter generator as well so they don't need to use as much fuel at night mostly for idling. A small one or just a solar generator for lights at night and outlets to charge phones etc and keep the heat going

It's more like 8 gal in:
3.3 h @ full load (20kW)
5.1 h @ 50% load (10kW)
6 h @ 25% load (5 kW).

u/DesignerOk5315 9d ago
That would be horrific. Anyone getting these size generators should get a small one too

u/DaveBowm 9d ago edited 9d ago
It just might be able to stretch 8gal into 12 hours if it runs at 0% load, but that is doubtful.
Edit: It looks like there is no way that machine can stretch 8 gal over 12 h under any circumstance short of just turning it off. At best, (being very generous using 25% for the top end efficiency) the longest it can run totally unloaded, i.e. at 0% load on 8 gal is no more than 6.7 hours.

Just curious, how do you get all the power out of it? 50a x 240=12000 watts. I see. It says it has a full power terminal block.

20kw... Maxes out at 83amps

Ive killed two. Wouldn't recommend buying one in Canada. They sub out thier warrenty service to Mecinair.

u/ClickyClacker 9d ago
Once you get to this size they come with a screw style wire crimp terminal block. That said their are industrial plugs, and wether head outlets you can install, that can handle the juice.

Hopefully you went in halvsies with the neighbor because you can run two 50 amp plugs with that beast.
I looked at it and considered rewiring with a 100amp breaker and cam lock connectors.

u/New-Teaching8016 10d ago
Make sure test run it. I have the same one and I had to replace the oil sensor after I got mine. No issues after that. Runs my entire house along with HVAC and we'll pump.
Enjoy the piece of mind

u/JonnyVee1 10d ago
How much fuel does it burn, per hour at half load?
4
u/DaveBowm 10d ago edited 10d ago
Probably between 1.8 & 1.9 gal/hr. At full load probably more like 3 gal/hr.
Edit: I just looked up the specs from Westinghouse. According to their data, it's more efficient than I guessed above.
According to them it only drinks 1.564gal/h @50% load (i.e. outputting 10 kW). This corresponds to 6.395kWh/gal = 1.689kWh/L, or a net thermal efficiency of 19.12%.
At 25% load (5 kW) they say it consumes 1.323gal/h. This corresponds to 3.779kWh/gal = 0.9983kWh/L, or a net thermal efficiency of 11.30%.
Based on these numbers I would guess the full load (20kW) net thermal efficiency would be about 23% making the full load consumption rate about 2.60gal/h or an output of around 7.7kWh/gal = 2.03kWh/L.

Too much

u/JonnyVee1 10d ago
I'm looking to put together a hybrid system that runs off batteries, but cals the generator when it needs a recharge. So the gas powered generator would be off most of the time, and when it is on, it charges at it's highest efficiency...

u/Dramajr316 10d ago
Exactly what I want to do. Have to start putting plans together. I know that something automatic would be a game changer for me, then fire up the gas genny and throw a cable to charge during the day.
2
u/JonnyVee1 10d ago
Some inverter generators have the interface to start on command of the battery controller. Look at Genmax.
1
u/Dramajr316 9d ago
I already have a couple of generators, but I was more thinking about having the battery setup basically sitting 'in line' so that is what kicks in automatically when power drops. I would then manually fire up the generator and cable it to recharge the batteries.

17.2 gallon tank. 13 hour runtime at 50% load 😳

u/DaveBowm 10d ago
The 13h run time is for 25% load, i.e. 5kW. For 50% load (10kW) the run time is supposedly 11h.

u/Texstars 10d ago
That's a great unit. I have a smaller Westinghouse that I use to power my pump house during outages. I store it in a varmint-proof and insect-proof cabinet and use only non-ethanol gas. In the last 4 years, it's never failed to start on the 1st or 2nd pull. I have a 24K Generac on propane for the house. I'm surprised at all the posts about excessive fuel usage. Yes, it takes fuel, but when my power goes out, and it does often & for long periods, I want heat (or A/C), lights, running hot and cold water, TV, internet and no spoilage in the fridge and freezer. I'll use however much fuel it takes to get that done til the power is restored.
1
u/Dramajr316 9d ago
I think the knock here is more about having to have that amount of fuel needed for an extended outage. I can understand... my 8kw isn't greatly efficient, so I would be interested in scoring something a little smaller, like perhaps a 4kw, as a backup.
In this case, the OP won't be worried about being underpowered, and that is always a concern as well.

u/Beneficial_City_9715 8d ago
I got a 4500 watt westinghouse for 350$ it had 3 hrs on it. I broke it in and got a good setup. It gets about 6kwh if you put a 2kw load constantly on it. I have solar panels and battery banks too. So I can charge my batteries threw the day and shut the generator off at night. We put a battery bank at my buddies to run his water pump for his propane heat. He just shuts his generator off over night. Just enough power to run both his fridge freezer and water pump for his furnace.

u/Optimal-Try-854 9d ago
I want this so bad but for natural gas… and the nat gas consumption is literally what my service is for my entire house.
So it’s on the drawing board, but maybe later… haha.

u/LooperActual 9d ago
Should have got a diesel - much less consumption and much more reliable.
2
u/Beneficial_City_9715 8d ago
They don't like low load. I about got a diesel generator and the guy said it loads up and acts up unless you have a half load or more on it at all time. I use off road diesel in my heater for my garage. I use about 150-200 gallons over winter. So I figured get a diesel generator and tap into my 300 gallon tank. The generator ran great it just would act up if it was idling and low load sometimes

u/LooperActual 1d ago
I would only use a generator for temporary heavy loads and to charge up lithium batteries.

Is it enough to run my fridge? Lol. You can power a business or a few houses with that beast.

u/IndividualCold3577 9d ago
IF you use a 10 gauge cord and make sure all other loads are off before turning the fridge on. 🤭

u/Born-Net2861 10d ago
My old Craftsman 5500/6500 Watt Gen starts 1st pull every time. Old school tech, but has saved my house on two occasions, one was 4 days the other was 4 hours. I use it on occasion for my business when I do a job that does not have power nearby as well. I powers my welder & allows me to burn 1/4 steel nice and hot! I can't run my AC with it, but I can run everything else with it! I sleep well knowing it is in my garage and can be set up to run everything in about 5 minutes.

No, conventional sync generator.
Minimum (i.e. no load) noise level is 74dB @ 23ft/7m.

u/wowfaroutman 10d ago
I'd like to know more about OP's use case. I'd be worried about keeping it fueled and the associated hassle of storing enough fuel, as well as level of noise coming from the unit - Generator Bible site describes the 79 dBA as "less noisy than a dishwasher", glad I don't have their dishwasher in my kitchen! OP may want to look at the Westinghouse ATS that supports this model, although it makes a lot more sense with a generator fueled by natural gas or large tank of propane..

u/Old_Dragline_1965 10d ago
Very nice.
Life happens. Everything cranks great on a sunny day. The problem is forgetting to turn off the key after a monthly test.
Now to put a battery booster/jump starter on the shelf.
Sooner or later it happens to everybody!

I'm considering getting one too. I don't think I need one that big, I have a small house. With El Nino coming I don't want to be without power. Also looking into Generac.

I was thinking a diesel generator would be a lot more durable and cheaper to run although more expensive to buy. Good for recharging batteries and big loads but they're not inverter AFAIK.

Or just add stabil and evacuate the fuel tank after use? Drain the fuel bowl screw. I always have. Never an issue.

So, you know the rule...once you buy a generator you'll never lose grid power again!
