Hi all.
I recently installed the smart shunt and I can see it can monitor the mid of a battery bank. Can you tell me where to monitor exactly?
Also should I connect the negative from the MPPT as "a" or "b"?
Thanks

Monitoring mid of battery bank
A couple of other observations:
1) for most accurate voltage readings on the Smart Shunt you should connect the positive lead directly to the battery. Depending on the length of cable between the positive battery terminal and the fuse there could be some voltage drop.
2) You don't show a fues in the MPPT positive connection to the battery. If that wire were to short to ground sufficient current could flow to cause a fire or at least melted wires.
The SYSTEM negative is the load side of the shunt ("b" in your diagram). All loads (and frame/earth ground) should be connected there. Nothing on the battery side of the shunt except for the battery. If you connect loads (or the MPPT) to the battery side of the shunt, that current won't be measured by the Smart Shunt so SOC and other calculations will be incorrect.
Thank you very much for your answers - makes very good sense.
