Showing no Solar Volts/amps on MPPT 100/50

My MPPT 100/50 is reading .01V and .0A which is false. I'm producing about 75 volts from my panels. The charger is blinking blue on bulk every 4 seconds and the batteries are charged to 100%. Why isn't my mppt reading the incoming voltage? Thank you for the help.

I can't quite zoom in far enough to tell, but is that not a "-" symbol over there on the far left of your multimeter under the DC symbol? If it is, that indicates -75V, meaning your polarity is reversed, which the controller won't see - if your PV polarity is reversed at the controller input, it will read "0v". Worth checking - like I said, I can't actually zoom far enough to be sure that's what it is.
