That came up in discussion with another TC owner recently, comparing upgrade ideas. Is 24v really worth it for the short distances involved inside a TC, particularly if you don't have to hang it all the way out on the back? Honest question, as I'm (obviously) fairly new to the inverter/charger world.I decided to go 24V, 280AH bank, with a Growatt, then a 24V to 12V buck converter for the step down.
Part of the planned upgrade includes replacing the two 12 vdc ~85 ah FLA batteries (completely un-marked other than brand name 'Alliance', so that's my best guess on ratings) with (at least) 200 ah of LFP batteries, which in addition to giving me quite a bit more storage capacity... should allow me to get rid of the plastic 'tub' that is the externally accessible battery compartment, and put a regular baggage compartment door on it. That *should* open up some space in that area, and make what there is a whole heck of a lot easier to get to.
Between that, and the under-sink cabinet in the (dry) bathroom that I've earmarked for controllers / switches / bus bars... I *should* be okay. If the inverter/charger fits where I think it will, all the major DC sources / loads should be within a couple feet of each other, and the rest not a whole lot further. Definitely 'snug', though.
