The high voltage alarm clear value is set to 1V, this is the voltage that the battery needs to get to clear the alarm.

Tap the High voltage alarm, and set the Clear Value to 28.4V

Then when the battery voltage falls below that value, the alarm will stop.

Thanks Guy, it worked. Alarm clear value was very low. Bravo.

Hi @Jairus Onsafari,

Check the BMV settings in VictronConnect, in the Misc menu, to make sure that the Aux input setting is correct. For example if you have the battery mid-point selected, but wired across the full bank (instead of the midpoint of the battery) you will get an alarm.

Then check the alarm settings and make sure the alarm thresholds are correct.

Maybe post some more screenshots of those settings screens if that doesn't help.
