Over voltage reconnect is exactly what it says. If the voltage goes too high and there is a disconnect... the controller will wait for the voltage to drop below the re-connect voltage.
This way it does no flip On-off-on-off at exactly the over volt disconnect voltage.
The over voltage disconnect should be set about the same as the BMS protect voltage and the reconnect should be a few tenths below. The charging should not be controlled by this function. This setting is to protect battery and components from over voltage damage.
If you were able to set the reconnect to zero you would have to disconnect the battery for the reset.
