Hello everyone!
I am using BMV-712, MultiPlus 12-1600-70 and MPPT SolarSmart 100-50.
I have two 255AH batteries in parallel (AGM LifeLine).
+B1 from shunt is connected to the positive pole of one of my batteries.
I kept everything as default, I just changed the capacity to 510AH.
Also, I have synced the SOC to 100%. But it shows the SOC 99.9 when the voltage dropped to 13.1, and 99.7 when the voltage dropped to 12.85.
Based on the instruction for using solar panels with BMV, I put charged voltage on 14.2V, below the absorption voltage which is 14.4V. I still have the same problem.
I kept everything as default,
Charged detection time 3 min
Charge Efficiency Factor 95%
Tail Current: 4%
Puekert: 1.25
Why the soc is not match with the voltage? 99.7 when the voltage is 12.85.
I would appreciate if you could give me some advice on it.
Thanks in advance,
Milad
