If I have a busbar with 6 lugs but have to connect 8 wires to it, can you put 2 wires on a single lug? Of course the busbar would be rated to handle maximum amp load of the system.

@HRTKD appreciate showing what you connect where on the Busbar! I have a similar system, with two cc for two different arrays (one is lower voltage/amperage). My question is that when I add an additional set of 6v batteries in series--is it okay to have both negative batteries flow through my battery monitor shunt--one negative going from shunt to busbar... but then my TWO battery positives going to my busbar? Looks uneven--is that okay?I have two solar charge controllers, so I put the lug on different studs. Something like this:
Thanks @Hedges appreciate reigning in my analysis paralysis I have a switch i planned to install between my two 6v series positive and busbar. Not sure how I’ll tie in another series of batteries to the shutoff and busbar down the road, but will post that question later after I research more!In my case, there is only one positive lead from the battery to the bus bar because there is a switch between the battery and the bus bar.
The optimization of the wiring arrangement is probably only good for .001% better throughput. So don't overthink it too much. Otherwise, your plan looks OK to me. Maybe put SCC#2 on the open stud.
