According to my Victron shunt's "history" my average daily consumption is 112Ah (average discharge).
Counting 26.4V average, that's just under 3kW. For 24 hours.
OK, I run cold cycles on the washing machine and switch off lights when not needed.
Say you have a slightly more "can't be bothered" attitude and use four times that. 12 kW.
On top of which, there is the A/C.

Now, the A/C will not only drain you batteries, you will need a bigger inverter to run it. Which, however big, will still huff and puff (make fan noises) most of the time. Make sure you put it outside ;·)

But the point is... if you can reduce the A/C's consumption, you can also save on batteries, inverters, general aggravation.
So, probably worth to do some research - and spend some money - on that.
HVAC pumps sound interesting. Rheem et al. make gas (as in propane/butane/etc, not petrol ;·)-powered air-conditioners. If you have a propane tank, rather than bottles, they might be worth looking at.

Now, I have zero experience with A/C. I actually dislike it, I can take the hot and humid, it's the cold I don't like.
But just saying, if the A/C makes all that difference in what your system needs, it's time well spent to look into it, and money well spent to get a good one.

Going to replace the ac , it's 12yrs old and has a 9.1 seer rating . I will check that propane ac out , never heard of one. I have heard of propane refrigerators though, so it makes sense. Thanks

What's a signature block? Do I just click your user name? That's great info. I'm changing the existing ac units out , they are garbage . Hoping I can get the consumption down significantly. Thanks

If using a phone, may need to turn it sideways.

You most likely already know this but will mention it in case it helps someone. When you do change out your AC units if you choose an inverter type mini-split (There are several models available where 1 outdoor condenser can service 3 to 4 indoor Evap. units in different rooms) it will solve 2 issues. First will double your present efficiency of 9.1 and second, by virtue of the way an inverter motor operates, will eliminate the need for a soft starter to reduce inrush current.

That's a great idea!

Is it possible to do some geothermal to reduce the A/C demand?
 
Sorry WY , I spent 20 yrs at 5800 ft of elevation in Utah dealing with all the B.S that goes with that... never again!
 
Ok. Now I’m curious about the issues with living at 5800 ft….

Somebody beat me to the inverter minisplit. And in case you haven’t seen it yet. Mr. Cool seems to be a diy-able system. Lots, and lots, of installs. Maybe check out the Garage Journal Forum.

And welcome!
 
Looks like I can reduce my daily usage significantly by changing out the old ac units. The old unit pulls 3380w according to the manual and a new one specs out at 1880w.

Where I was it's cold , weeks where the temps were high teens, lows in the negatives, snow, lots of wind, I've seen 70mph gusts , coldest day ever was -26f . Frozen pipes, plastic truck door handles snap off if you try to open them , if you get the door open it shreds the door gasket.
Miserable for 9 mos a year. Beautiful for 3 mos

Yep, except I got to see -32 Fn degrees. Only miserable here for 4 months tho. Gonna pack my stuff and head for Loreto, BC, my favorite spot on the east coast of the west coast. ?
