I have a BMV-700 hooked to a 12V lead-acid battery, powered by 2 Blue Solar MPPT 75/15 controllers. The BMV is hooked up correctly - it shows proper voltages, power, current (with the correct sign), ... - but the history item, "J SYNCHRONIZATIONS" is stuck at 0. I assume that when the BMV encounters the correct conditions to perform an auto-synchronization, it should increment this counter. Am I mistaken?
Here are the relevant BMV parameters I've changed (the rest are left at default values):
01 Battery capacity - 242Ah
02 Charged voltage - 14.4V (the charger controllers are set to 14.7V absorption voltage)
Now, I've watched the monitor, and I know that the battery has exceeded 14.4V for more than 3 minutes with a current of less than 9.7A, so it should have automatically synchronized. The battery icon is not flashing (I have done some manual synchronizations). Any idea what's going on?
