Updating DC System

1. Negative bus bar

2. Distance is not an issue but wire size is. I would size for minimum loss - 3% or less.

3. I wire all battery cabling the same size - most often 2/0

How do I size a new alternator? Should it be based on the battery bank size.

With the ACR wires at 2/0 you no longer technically need the fuses on each buss, if you don't want them.

These fuses are there only to protect the wire. If the wire shorted the battery fuse would blow and you'd be protected from a fire.. If you want to keep them feel free but it could save some money by using the fuse on the bank as your OCPD..
