Mttp1 not functioning
Good day
For some reason 1 of my solar inverter batteries is not charging at fill capacity, the mttp1 is not being used at.
It was working fine for a few months and just stopped.

To confirm that the MPPT may have failed, you could try swapping the PV inputs. If the problem follow you then it is the PV string, if not then it is the MPPT controller.
