I have a BMV-712, I recently performed the latest update and even though I was next to the unit, it failed. I lost AH consumed for a day and it eventually came back. It reported as 0 and after charging it seemed ok.
Then odd things have started to happen, the ah consumed was showing say 250 and when on charge, this dropped to 180 and the voltage was high enough to indicate that the batteries were almost fully charged, I carried on charging until the current going into the batteries was uneconomical to continue at 10A (24v tubular batteries). I adjusted the SOC to show 98% which seemed realistic.
A few days later and now it is showing that I have consumed 260ah and the voltage of the batteries is high enough to show that the battery is Almost charged, the solar has gone into absorption. Normally with a fully charged battery it does this at 85ah consumed.
I really cannot trust my BMV right now. Will a reset work? I cannot see in the settings how to do this.
I really do not want to loose all of my data stored on the BMV. What can I do?
