I want this. I can’t imagine achieving WAF.
Non inverter generators for home use.

around 6-7kva, so similar to yours.
Kubota makes a 7.5 kw that’s in an enclosure for around $5.5k. It’s for construction sites. Under 50% load, I think it uses around .25 gallons an hour. For me, a whole house that was more than double the kw’s was just a little more. It’s automatic so no hassle when it’s needed either.
bumping this. i'm actually curious of and unfortunately the non-inverter style is getting difficult to find. I've been told some models of the pre-inverter era actually make 240v, they just dump each leg to each half of the single duplex outlet on the machine and sharing the neutral.
I'm in desperate search of such generator/alternator. 2000-2500watts would be plenty. It'd be the killer for my portable stick burner box. it runs on 120/240. two car batteries work, but it's kinda crude, and the're so heavy.......
anyone that reads this, please fire up their old school rig and poke a meter at it. and share the make/model.
thanks.

Generators with low power output do not use 240v in the duplex. I have checked mine specifically for this. Coleman 4200 Powermate ER
A Predator 4000 or 4375 would fit that description. Used to have a 4000, upgraded to a 9000. A 4375 is a non-inverter.
I agree as during one power outage my GE washing machine wouldn't run off low level Powerstroke Home Depot generator.
That is likely to be an 'off frequency' and not a dirty power problem. Unless the gen head is absolute junk.
I'm very experienced running 'off grid' due to hurricane power outages. The only time I have issues is when the frequency sags below 56HZ due to excessive load. Then my GE appliances give a power failure message.
Need to play with the carb. Some shimmed paper and a propane hose down the throat, I can make 12amps before it gags out. The Westinghouse dual fuel looses 20% on propane as well.
Definitely non inverter. Not sure who makes it. 5hp Briggs is spinning it.
18.8amps, 120v, 3600rpm. Works great. I'll pop the cover off later and see what the spaghetti has to say.

Mine has to be older then that one
Same specs

Too big/heavy. My search of a small 240v generator might be a unicorn.
agreed. that's the #1 reason i went with an interlock. Yeah, doesn't flip the neutral, and required me unbonding the westinghouse DF9500. But the $35 interlock gives me whole panel flexibility, and basically 9000 watts is plenty enough to make the furnace run, all the lights in the house, 240v pump water ,and 240v heat water, ~38 Amps of 240v. I wish i could shower and do laundry in the electric dryer when the power is out ,but i guess not everyone can be a King during an outage. It might do it on gasoline, but the quality of todays gas is straight up garbage, and just isn't worth the risk to gumbo up a nice carb. I'll sacrifice a few amps in the rare moment i need it to not spend $25,000 on a whole house setup. I set up with propane off the 1000gal tank, as i didn't want to fight with gas cans, spills, old fuel, draining carbs, etc ,etc. Then chase down the fuel tank every 6-7 hours? And we both know the fuel station probably doesn't have power either! Now we're stuck with 90day+ old fuel and no way to get fresh stuff.
electric start with wireless keyfob and a flip of a breaker is hands down huge step forward compared to the extension cord mess, doors/windows can't close, mosquitos fill the bedroom and living room at night. Jesus,no more. And the ungodly noise is way out on the other side of the garage/house. I was going to get the 30amp/240v, but i'm so glad i didn't. For such little extra money this is a huge game changer of emergency standby power. I bought the 50amp with the intentions of never moving it. And now it sits on it's own poured cement slab with huge U bolts off a semi tractor axle dropped down into the concrete holding the frame down. There's theft issues around here.
You should be able to run the hot water heater on LP - at least I can..my water heater is 4500w and my genny makes 7500 on LP or 8kw on gas.
And as far as gasoline goes, I wouldn't worry about 90 day old stuff as long as it's in a good quality sealed container. In fact my neighbor and I got his genny running on last summers fuel during the tail end of this winter.. ran fine.
my 240v loads are water pump, water heater and dryer. i can only do 2/3. i can't run all 3, hence the joke of drying laundry while taking a hot shower.. On gasoline it might make all 3, but i'm not fretting over it.
I have no intentions of ever putting gasoline in it. I bought a $30 regulator to avoid playing with fuel containers and all that comes with it.
this little crappy Ag-magtronic thing is going to be my new portable. Alot smaller and lighter. sadly it isn't 240v. Runs not too bad on propane, i just poked the hose down it's throat, guessed at the knob on the tank, and runs nice. I might actually rebuild the carb on it.
Ohhhh... reading comprehension failure
it's been a few years since you posted. I, as well as others who's been poking at this thread, would like you to follow up if you've smoked anything or know of any issues pumping power with a THD of that unit.
This Westinghouse is around 23%, i took a gamble, and so far it's had nothing bad happen running off it's power. It probably doesn't help with the THD, but i have one of those full house protection surge arrestors that goes right in the main panel, apparently that's NEC code now, too? If anything it'll sponge any voltage spikes from loads coming off while the RPM has a chance to mellow out. As mentioned, since everything is rectified for AC>DC, and a million capacitors, i think it would be quite difficult to burn up anything electronic, especially if it's on a battery, as most battery devices, well, run off the battery, even when plugged in 'charging'. It's the same concept why you shouldn't disconnect a battery in a running vehicle, or try to run a vehicle if it does run without a battery hooked up, if the voltage regulator has a hiccup, there's no battery to sponge the spike.
Probably the only item in the house i wouldn't trust it on, maybe is the microwave with the magnetron. Fridges, new or old, and heat pumps/air conditioners, those compressors HATE low voltage. I wouldn't dare run anything like that unless the load on the genny is at least no more then half. Just not worth the risk.
But overall I just don't think they make any <3-8% THD generators that'll supply 240V of 50 amps, inverter style or not. Then my picky picky pickiness i wanted propane and pull start for those serious just-in-case moments.
I had one years ago. It was made/sold by Sears with a 4 or 5HP Tecumseh engine. 2500W, 240V/120V. It was a terrible setup and the engine actually had an external oil catch tank right from the factory, as when ever it ran, blowby moved it's oil overboard. I'm not one to throw out a generator, but that one was useless and ended up on the street.
About the only good feature is that it had a single carry handle.
