My catastrophic failure fuses are 350 amps each. My wire from the battery buss to the controller is not capable of sustaining 350 amps, so I would fuse to the wire size between the controller and the battery bank. The rule is "always fuse to the wire size".
This is one reason, and here is another.
If battery fuse blows - between the battery and buss - but the loads breaker remains open (let's say for some brief time?) - then controller remains connected to loads via the same buss, while not connected to battery. No good.
