Hi,
I have newly installed solar panes (4xSP 104 Solbian) 2x MPPT 75/15.
In history view I see that they have been producing some power and charging batteries. I’ve only connected to controlers on the second day. At the time of first connection with the app update of firemware was mandatory. Since then panes are not charging the batteries.
Thank you for your help.

As an additionalk info I think battery voltage reading on the solar controller is wrong. On the boat pannel I see 12.3V and MPPT is showing 13.6 - both MPPT units show the same / similar voltage of the battery.
Hi all,
Problem solved! It turned out to be fuse at the battery. Instead of 20 it was 5 (both versions are yellow only 20 is a bit darker one and at instalation a mistake was made). Now I have 15 amp fuses and it works great.
@M.Lange you were right :-)
Thanks all for help.
