This was assessment from Bimbly, I guess main question would be whether that MPPT would still be good if I add more panels for winter - I could reduce amount needed by doing without fridge in winter - I would love to be 100% solar - Im one of those filthy environmentalists. Thanks so much everyone for all your tips so far, really so so useful as Im a beginner at this kinda thing
