Go into the settings and change the set point for high voltage alarm.

You may have connected the batteries in a series mode giving you twenty four volts.That is where the high voltage signal could come from.

Be safe and take a voltage reading with a volt meter. Better safe than sorry. I believe anything above 14 volts could be high for the unit...not 100% sure...

Alternators charge at 14.4 volts.. So I doubt that would be too high. Anything over that would be abnormal

24 volt batteries could put out 26 volts when fully charged.
