  Michael JohnsonAug 9, 2025
  If the load indicator on your Renogy Controller is flashing white, several issues could be the cause. First, use a multimeter to check the battery voltage to ensure it's not exceeding 32 volts. The load circuit on the controller might be shorted or overloaded; ensure the device connected is properly connected and doesn't exceed 20A (DC). Also, check the LCD for any error codes.
