I bought a 300W boat solar kit (3x bendable 100W monocrystalline panels and accessories) from @renogysolar, and upgraded the charge controller to an MPPT charge controller also from Renogy. I got 2 group 31 AGM batteries (wired in parallel for 210Ah) from @westmarineinc along with most of the wiring, fuse panels, circuit breakers, and shore power charger (have not had to hook up to shore power since the initial charge!). Picked up other miscellaneous supplies from Home Depot (the circuit housing in between the batteries, housing the fuse panels, busbars, etc.), Amazon (some inline fuses for each solar panel, and other miscellaneous things it was hard to find elsewhere), Fry’s Electronics (the 400W pure sine wave inverter–total overkill for my needs, as I haven’t even hit 70W real use through it, but that’s the idea), Camping World, and Autozone (tiny ins and outs like 2 separate 12V ports).
Everything is fused multiple times (plus 4 major circuit breakers–one on each battery, one at the connection of the positives from each battery, and another before the primary fuse panel), and the vast majority of everything is oversized for the load I ever put on it. Not shown, also is a NASA marine BM-1 battery monitor and (previously pictured) the monitor connected to the charge controller. More than meets all my needs! The solar panels are tied to the roof of the car when I’m stationary (still perfecting technique, but have used bungie cords and paracord, both to varying degrees so far), and then easily stack and slide in on top of all of my stuff in the trunk space when I move. I’ve considered a more permanent solution, but have held off so far. Came in around $3k total, doing the wiring and setup myself. A few bits need to be redone already, but I patched them up to a safe degree for now (nothing dangerous, but if I yank real hard at the right spots, I could break a couple of connections). Maybe fix it more this weekend.
