The fuse goes between the controller and battery to keep a short circuit in the controller, sourced by the battery, from starting that fire.
The wire and its fuse from the positive bus bar to the battery must be of sufficient ampacity for the total of all the amps going to the bus bar.
Individual positive wires and their fuses of various ampacities that go to the bus bar from different things (inverters, converters, solar controllers, jacks, slides, etc) need their individual fuses for their own wire sizes where their wires go back into the walls for different 12v things.
It is not good enough (AFAIK) to depend on the one fat wire's fuse at the battery to protect all those various wires of various AWGs that go to the bus. Any one of those wires could short by itself and needs its own fuse for that.
