Hi, I'm learning about the Victron ecosystem. As I understand it so far:
- The error A-B11 for undervoltage comes later than the load disconnect is triggered, when the batteries are further discharged.
- When the load disconnect is first triggered, charging is still allowed.
- The BMS will allow charging (as long as the batteries are warm enough) until A-B11 is triggered.
- The charge disconnect signal only triggers for overvoltage, not undervoltage.
If the above is correct, is there a way to detect A-B11, or the fact that BMS is not allowing charging specifically because of undervoltage? I am trying to understand how it was achieved in this video. One of their Orion is used for trickle charging the battery (at 0.1A then 0.1C until the battery recovers) and is only activated in case the BMS disallows charging/is completely shut off. I wonder how to detect this to achieve a similar setup. Thank you!
