Yep, the batteries are the gating factor.....

If you can read past the 'Valley Evangelist style of delivery, some interesting data on recent progress.

I found out about these better mouse-traps today....

"Whirlpool Duet WD99HEDW ventless heat pump dryer, while LG sells the DLHX4072W".

Whirlpool® HybridCare

I didn't know that configuration of dryer was on the market. Big laundry loads in a high kwh market might make that worth a look.

I suppose it needs a condensate drain--like a mini-split? The water has to go somewhere. Normally the washer drain would be nearby so that may be no issue.

I haven't seen the installation details on these Dave, but that would be my guess too. On new installs, you'd have one less (vent) hole through the wall, as a bonus.

Yep, getting rid of the vent piping and hole could be very useful in most cases.

It's stretching things to call this off-grid, but clearly Natgas is getting more popular in areas with high electricity rates.

The 18 cubic feet frig says it uses 1.8 lbs of propane in 24 hours. The conversion factor for a gallon of propane is 4.22 lbs.

1.8/4.22 = 0.4265 gallons per day. At $2.25 per gallon that's $0.96 per day.

I've known a few off-grid folks with a propane frig and freezer. There are also kerosene refrigerators used by the Amish mostly.

I've been impressed with the RV propane fridge/freezer units I've used. Stands to reason, that system could be fired with Natgas.

AC Sunfrosts are pretty efficient. If I was going to spend that kind of money, I'd be tempted to go DC - one less conversion in an off-grid system, and easy to time-shift battery charging when using TOU grid power.

I would prefer electric, DC or AC, over gas off-grid. It just seems easier than keeping a propane tank filled and the energy cost is fixed at the time you buy the off-grid system.
