Demanding that power be 100% solar reminds me of cruising sailboat skipper who demand every inch of the voyage be done under sail.
IMO, a hyperbole with little relevance. You can't accumulate wind, not without complicated equipment. Solar energy you can.
It boils down to solar harvest (=array size) and consumed energy out. If you keep cycle shallow, you won't need a lot of amps, not very often.
For the OP possible solutions would be getting a less demanding battery brand and (maybe) splitting the bank once in a while. With his loads I would try a smaller bank, 300AH.
