Newbie- Off Grid Cabin c/w gen support - What size bank 24 or 48

[bigdoughball]

Sorry to mis inform you Sunking. I have a battery charger / converter IOTA DLS-27-40. That's the one I am going to exchange for a 48 volt IOTA charger. Sorry for that misinformation. I did say cc. But at least you have given me the info for solar panels and cc mppt. Thanks, that is next on my list. Yes, once you get your head around this stuff, it is all math. but a bet overwhelming at first, and it's very reassuring to check with you guys before committing the bucks. Very much appreciate your input on helping me.
