I observed an inconsistency of readings on my supervision, indeed the curve of percentage of charge went from 86% to 100% in a single blow (10 mins which is my sending frequency) while the sunshine was decreasing, here is a picture to illustrate:
Thanks
this is working as designed. Please have a look in the manual:
Page 12 2.2
This is called automatic batterie synchronisation. The BMV assumes that the batterie is fully charged if the exceeds a specified voltage for a specified time and a specified tail current.
These three parameters can be changed regarding your needs.
Hope it helps

Thanks for answered,
I knew this information but i didn't made the link with my issue...
So, i've to edit my BMV config... i'm not sure to know how to do this !
Here is my current config (for 8 batteries Rolls S550-6V)
Thanks for helping !
As i am not able to read fench i hope i interpret the right values:
The actual settings say: if the charge current is below 4% of the max amperage (428A = 17,12 Amp) for more than 3 minutes the BMV assumes a full charge.
You have to change either the amperage or the time (maybe both). I did not check the voltage -> hope the value is right.
Hope it helps.

After read my history, the max voltage (minutes before "float" state) is : 57.3V and charge is below 2% . I will edit my config with theses values.
Thanks for helped ! hope it will help others
