Planning my 12v system for my van. It's an old red cross ERV.
I have 412 AH of SOK lithium batteries already but haven't purchased anything else.
I am planning on a rather large solar array, as my vehicle is huge (112 square feet) and I would like to maximize the space with panels on the roof. But I'd also like to incorporate dc to dc charging.
I am wondering, since the renogy dc to dc charger with mppt has a max pv input of 25v, could I theoretically design a system with 4 100w panels in parallel running to the dc to dc charger with mppt, AND add another MPPT charge controller with an additional 600 watts (probably rich solar 200w panels in series)?
Is there anything I would need to be worried about with these two systems working together, other than wire size and fuses?
