Battery Fuses and Circuit Breakers

I am going with the following set-up:

  • Sunsynk 12kw 3 Phase inverter (max discharge 240A)
  • 2 x Hubble AM2 batteries in series

Should the breaker and the fuse should be sized for 300A (1.25 x 240A) - the inverter may be able to pull 200A from the batteries for now as the Hubble's are limited to 100A each on discharge.  However, if I added a third Hubble, the inverter will be be able to draw the full 240A.

By this logic should the breakers and fuses on the batteries be rated at 300A?

Any recommendations on breakers and fuses for this application?
