What to do if MidNite Solar Battery Charger display shows 0 volts in?
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.
How to fix MidNite Solar Battery Charger that will not power on?
Check for voltage between the Battery + and the common – on the blue terminal block inside the MidNite Solar Battery Charger Classic. If voltage is present and above 10vdc, contact customer service. If no voltage is present, trace back through the + and – to identify the fault.
How to troubleshoot a MidNite Solar Battery Charger Classic that will not power on?
If your MidNite Solar Battery Charger Classic will not power on and shows “No self test on power up”, check for voltage between the Battery + and the common – on the blue terminal block inside the Classic. If voltage is present and above 10vdc contact customer service. If no voltage is present back step through the + and – to find the fault.
How to turn on Mode on MidNite Solar Battery Charger?
If the MidNite Solar Battery Charger display shows “Mode is Off”, enter the main menu, select Mode, turn the Mode ON, and press Enter to save the setting.
Why MidNite Solar Battery Charger switches between Resting and Bulk MPPT?
If the MidNite Solar Battery Charger Classic switches between Resting and Bulk MPPT repeatedly but produces 0 watts, monitor the IN voltage. If the IN voltage remains stable when the Classic transitions from Resting to Bulk MPPT, contact customer service. However, if the IN voltage gradually drops to battery voltage (or close to it) during the switch to Bulk MPPT, it typically indicates a high resistance connection, such as a loose connection between the Classic and the DC source.
What to do if MidNite Solar Battery Charger Classic says “Resting”?
If the MidNite Solar Battery Charger Classic says “Resting” when the sun is out, verify that the voltage on the display under “IN” is greater than the battery voltage. Also, confirm that the charging mode is correct for the source and the mode is set to “ON.”
How to fix a blank display on MidNite Solar Battery Charger?
If the MidNite Solar Battery Charger Classic display is blank but the Classic is on, check that the blue cable is securely plugged in between the display and the topmost jack on the circuit board. Try using another cable; a standard short 4-conductor phone cable will work.
Why is the display blank on my MidNite Solar Battery Charger Classic, but the unit is on?
If the display on your MidNite Solar Battery Charger Classic is blank, but the Classic is on, check that the blue cable is securely plugged in between the display and the topmost jack on the circuit board. If it is, try using another cable. A standard short 4-conductor phone cable will work for testing purposes.
