Not being able to charge below freezing shouldn't be a problem if you keep the batteries indoors. Is there a reason why you wouldn't? Fire concerns? Or is it just a space issue?

Yes, sorry, I was in a rush and didn't explain enough. For our usage, the cabin isn't occupied during the winter, and can drop below 0*C occasionally. The solar system is turned off though, so we don't worry about it.

If you're permanently there, it shouldn't be a concern. Sounds like modern BMS can disable charging at low temperatures so maybe not a worry for you at all if you're buying new batteries.
