The box is an enclosure. Protection comes from the breakers, SPDs and voltage protectors you fit inside it.
Yes, that is what IP65 is for: dust-tight and protected against water jets, as long as the cover is closed and the cable entries are sealed with glands.
A single-string solar DB (DC breaker, DC SPD, AC breaker) usually fits in HT-8. Hybrid systems with AC SPD and changeover need HT-12 or bigger.
No, the box comes empty. Add DC breakers, DC SPDs and AC breakers as you need.
