I have a challenge with my BMV-700 SOC. It displays to high SOC.
I have a 24V battery made of 12 x 2V 1100Ah AGM cells.They are 10 years old, so they are most likely not any longer 1100Ah of capasity, so I have downgreaded them to 1000Ah in the BMV settings. However that is not the problem (I think)
For the last six days the consumption has been net 8.7Kwh (Very little sun in Norway right now, but we do get a white Xmas)
The SOC of charge however only drops from 99% to 86.5% indicating a consumption of 12,% of (24Vx1000Ah) = 2.88Kwh - that's clearly incorrect.
What do I do wrong?
Snapshot right now: 13% <> 250Ah - Does the BMV think I have a 12V system?
