can i link a smart solar 100/50 to a 150/85 mppt
what cabling do i need
is there any literature on doing so
thanks in advance

@Robin I take you mean at their outputs, the feed to the batteries. Yes you can link the as you can any charging source.
Cable wise it is dependent on the distance to the batteries and max current assuming 50A and 85A and cable runs of lets say 2 metres.
For the 50A I would use 35mmsq which would give 0.50% voltdrop at 30A
For the 85A I would use 60mmsq which would give 0.49% voltdrop at 50A
The shorter the cable run the better if you tag me and let me know the cable run distance I will calculate the cables I would use for you
@Robin They don't need to talk to each other in the sense of VE bus etc as they sense what is going on via the voltages on the charging line and through the important charging period Bulk absorption work together. When the voltage rises one or the other will back off and leave the other finishing the charge. If it is a Lithium system using Victron VE Bus etc yes they can be controlled by the Bus, but never found it needed as far as charge levels etc are concerned. Hope that helps
Additional resources still need to be added for this topic
