Charging Connection Positioning - Bus Bar or Direct to terminals

Hello,

I was wondering what impact the position in the circuit the charging connections has on the batteries it's charging.

For example:
I have a battery, a solar charger and a DC-DC charger.

The battery negative goes to a shunt then to a negative bus.
The battery positive goes to a positive bus.

Can the solar charger/DC-DC connect to the bus bars? Inversely, should charging connections be directly on the battery terminals?

If connecting to the bus bar is fine, what things should I watch out for? Is there a preferred ordering on the bus bar for charging, battery, output connections?
 
Connecting to the bus bar should be fine.

On bus bars, I like to put the highest current items close to each other in the middle and the lower current connection out from there. That way the high current paths see the lowest resistance. Typically that means the battery and inverter are right next to each other and every thing else on either side. (Frankly, on heavy duty bus bars it probably does not make much difference but what the heck, if you can do it that way, why not?)

BTW: I did not see a mention of a fuse on the battery...???
