Is that a tolerable difference or do i have to fix smth? Also where do i have to set the cable for midpoint measurement?
Thanks and best regards, Tobias

@iBot All batteries have a different voltage: 13.28V, 14.25V and 13,.4V.
Your pics show batts A,B,C show voltages very close together, about 40mV deviation.
More importantly the batts show "balanced" meaning that they have been fully charged to the point that each battery considers itself fully charged and balanced in the last 30 days.
Your mppt shows a full charge with a complete absorption charge, before settling to float.
What seems to be your concern?
BTW typo in your post about the voltages. My heart did a skip there then i checked with your screen shot. Phew.
Answer is it is tolerable. Thay are all at 13.2v. It is quite literally 0.04v difference between highest and lowest. Probably a little to do with lugs stacking there. (But I understand space issues)
You can't do mid point measurement with your set up and bank voltage.
Thanks to you both. My concern was about the 0.04v difference. Good to hear that this is acceptable.
Additional resources still need to be added for this topic
