Mppt 75/15 not charging

img-1793.pngI have two 115W solar panels connected in series to an appt 75/15 regulator and two viltron batteries connected to the regulator. This has worked perfectly for some time but the regulator now seems to have lost the ability to read my batteries.img-1794.png

The mart is not reading the voltage on the battery and is not charging. I have checked the battery output on the ppt and it is correctly reading the battery voltage but does not seem to be using it and is not charging.


Any suggestions?

We already had that topic many times.

Check all connections and fuses between the battery and the MPPT. There is also a fuse directly at the MPPT.
