I have a Samlex 3012 inverter charger that is powered by 4 x 100 ah LIFEPo4 batteries. Each of the batteries is wired separately to a bus bar using 00 welding cable, this bus bar feeds another one tha...

I am not clear whether you have allowed for the proper method of fusing "branches" and the output of a bus to total the amps of all the branches. I assume there are branch fuses not shown: inverter to bus, MPPTs, RV, Victron positive?
This is very good at explaining it all. Worth a look!

Thanks for the link!
