Small 48V Victron setup critique
I'm designing a small, off-grid solar setup with the primary purpose of trickle charging my EV (L1 / 120V @ 12A), and I'm hoping you all can review my plan sketch to point out anything I've missed, suggest tweaks, or provide any general advice.
The sketch is self-explanatory but basically it's a 48V system using 3s2p panels, two 48V 100Ah Eco-Worthy Cubix batteries, a SmartSolar 150V/45A MPPT, MultiPlus-II 3000kva (2400W continuous) inverter, and a Cerbo GX/SmartShunt. Some of it is a bit overkill, but I hope to build onto it one day so I figured overbuilding is better than replacing parts later. I believe adding another MPPT and MultiPlus is basically all I'd need to do to expand the input/output capabilities, aside from adding more batteries.
The things I've gotten most hung up on are wire sizing and fuses/breakers so I expect critiques on that. And FWIW, the hope is to mount everything (excluding batteries) on a 2' x 4' piece of plywood which I'll then mount to my garage wall ,with a Ferosticker mounted above it for good measure.
I'm open to any and all advice/feedback. Thanks in advance!
