Having both is not necessary. If you add too much joins and resistance to a battery setup is has adverse effects.

Most daisy link the Pylons and fuse only the cables going to the bus bar. And each battery has an on/off switch.

You do need a few more US3000 batteries for an 8kVa Victron to meet min spec. Ideally 5 in total.
