Smart 12 200 Bms system positive

My I am currently stuck as I can not figure out which way is best for me to wire a multiplus to the bms.

A quick overview of the system I am installing;

12/200 Bms

Multiplus 12/1600/70

3x200ah lithium smart

2x mppt 100/30

Cerbo GX (with touch)

Smart shunt 500A

My question is regarding the system +. In the manual it appears that a multiplus can be connected to the system +. Therefore meaning both charge and load can be taken from this connection.

Given this I would imagine it’s sensible to attach the mppt here too - leaving the bms to control the battery status.

I presume I can connect the rest of my loads to here too?

I’m a little lost as to why it would be needed to run a charge connect/disconnect directly to the multiplus or the mppt as stated in another example in the manual.

Any help would be much appreciated

If your cable sizes are OK, this will work. Assuming charge parameters correctly set of course.

Best is to bring all the positives to a busbar.

Think about fuses as well. Feed from busbar to fuse box for dc loads keeps things tidy.
