  Jason KingAug 5, 2025
  If the LCD on your Xantrex Controller is off, there could be several reasons. First, ensure there's a proper connection to the battery and check the fuse on the battery cable. If the battery voltage is below 8.5V, charge it as soon as possible to exceed this level. Also, verify that the solar panel receives sufficient sunlight to generate voltage higher than the battery voltage. Finally, confirm that the PV cables are correctly connected to the solar panels and the charge controller, ensuring matching polarity.

  Heather TorresAug 20, 2025
  If your Xantrex Controller displays a battery charging voltage outside of the normal range, verify that the actual battery type aligns with the charge controller's battery type setting for charging voltage. If they are incompatible, modify the battery type setting to correspond with the actual battery type.
