Dear everybody,
I am not quite sure whether my BMV 700 is calculating the SOC in the right way.
I have a 24 V system with two 150 Ah AGM Batteries in series. Fully charged when reaching 27.60 V (each 13.8 V).
During the night the batteries are discharged and and often reach a voltage level around 24.3 to 24.0 V. Then, the BMV 700 says the the SOC is 90 % respectiveley 86 %, see pictures below:
For me, 12.05 V are surely not 86% of the SOC as this surely needs to be quite lower as the chart (from the internet) shows:
What is wrong here? Can anybody help? Please also see my settings for the BMV 700:
Thanks a lot
Steffen
