so you are telling me that 6 200aH videos on a 48vcd system is only 200aH? Your math is off bud.

You would only result in a 200AH bank because you can only combine 4 of the batteries in series to create the 48V bank. The other two batteries could be combined to create an additional 24V bank or left as individual 12V batteries. If you added two additional batteries you would end up with two strings of 200AH 48V batteries. My math is fine.

I am getting clarification now. Even if I need to buy more batteries, its not a big deal. I am just going off what the customer service people told me. I am not above being wrong, but I am pretty sure they are not.

If you understood that diagram, please look at this.

So here is the verdict. If you go with this kit (https://theinverterstore.com/product...erter-charger/)

And add two additional batteries you are at 800aH of storage which according to them is well past the traditional 1.5-2.5 kwH most big systems in skoolies use per day.

Which is about 19.2 kwH of total storage and 10ish at 50% use. So even if I use an insane amount of power, like 4kwH per day, I would still be about 2.5 days before needing to charge and in an emergency about 5 days draining them to nothing without changing behavior. Which I cannot imagine would be the case.

Considering my my heater is propane, 84gallobs of fresh water, 180lbs (edited) of propane and rivers everywhere, I think I will be just fine.

That's only the case with a 24V system. You're doing a 48V system, so your capacity would be halved.

No you were right, I was misunderstanding but it has been clarified for me. I hope if people read this, they read all the way to the end because this stuff is confusing and was a good exercise in understanding how to really figure this out.

That's a hefty supply of propane, how big is that tank? I was looking at a tank that was 48" x 15" and only 29.3. You have 6x's that amount. That's about 750lbs

Its just the 100lbs tank with two standard 40lbs tank spares. The big one is like 5ft long, mounted underneath and the two spares can connect if needed.

Its a lot but being where I go, heat and food are all that matter, outside safely getting there and back.

You have me confused now. You said you had 180 GALLONS, now you're saying LBS. 180lbs is only 43 Gallons

The whole discussion of AH at a given voltage was an interesting exercise, but lost in the conversation was the fact that as you add more batteries, regardless of series or parallel installation, your total # of watt hours increases.

Going up to 48v does not reduce capacity, just how you count amp hours.

When using the same size of bank, fewer amp hours at a higher voltage still gives you the same actual watt hours delivered to your system.

Yeah what I was explained got lost. So I got the 24vcd inverter with 2 extra batteries, upgraded the solar charge controller and added two more panels.

My mistake in typing, its 180lbs so about 43 gallons. It will last easily a month of heavy use, with extra left over.

My whole question was based on 180 gallons which would be hard to mount on a bus and I was amazed you found room for that much.
This is the tank I want to mount in the right rear corner after removing the exhaust pipe in the way. 29.3 gallons

I have a 50# (11ish gallons) of the same brand. Lasts a very long time.

Last filled in June and have been using for cooking, shower and heat off and on ever since. Getting low now but lasts soooo much longer than I expected.

Iíve only filled it twice since installing it!

I'll need it for the range, shower, sink and possibly generator. I'll decide if I want to go with a form of propane heat after I see the wood stove drive me out from too much heat, or I'll need to learn how to build little fires. With 29 gallons it will be one thing I don't need to think about for awhile as you have seen.

The only trouble with a wood stove from my view is its illegal to carry wood across state lines which makes it a pain in the butt. But know they are super effective. I personally prefer constant heat rather then the heating and cooling back and forth. I have natural wood floors and its not good for them.

I can use scrap engineered wood, just not cut log fire wood that may still carry pests.
As effective as they are you can usually find enough "firewood" where ever you go to use for one night.
