What to do if MidNite Solar Battery Charger display shows 0 volts in?
- W
  Wendy HernandezJul 27, 2025
  If the MidNite Solar Battery Charger Classic displays a reading of 0 volts (or close to it) while the battery voltage appears correct, and if this is a new installation or has been recently altered, check for reverse polarity on the DC input. If this issue arises unexpectedly or after confirming the absence of reverse polarity, contact customer service.
