Outstanding. Thank you for your thorough reply.

Your battery schematic; does that result in 200 amp hours @ 24V? then you step it down to 12V to run the 12V A/C?

Do you need or want 24V for anything else in the truck? I do like the idea of 24V coming from the panels, if that's correct.

anyhoo... only curious. I'm a ways off from upgrading my neat little 12V solar setup using 500 watt PV, 300 amp hour AGM battery bank, 1500W inverter in a little 5' X 10' squaredrop I converted from a cargo trailer.

Reason I asked about your 12V A/C - sounds like a good fit for my little trailer. Then, there's the bigger RV trailer that will get it's own stand alone 12V solar power supplement to it's existing layout.

Cheers!

You are correct, 200 ah 24 volt system. I wanted a 24 volt a/.c but the outside unit is too big to go into the cabinet, and I didn’t want that big condenser hanging off the back door. Also , with 24 volt you can use smaller guage wire
