No solar voltage mppt 150/100

I've had this unit for almost a year plug into the batteries (no solar) I just got the panels installed and plugged in verified the panels are out putting 130v and when I connected it to the mppt through it's connectors the system shows no voltage coming in

I have trying swapping the polarity and same thing. I've updated firmware just B4 first time plugging in to solar. Why won't the mppt recognize the input from the solar.

When they are in the connectors (correct polarity) on the mppt does the digital meter read the voltage there on the terminals?

I have a new 100/50 charger that has a similar problem. My voltage meter reads 19.5v on the solar input cables and when I connect to the charger it reads 12.9 on the terminals. The chart shows no solar input. Charger is on and the bottom status shows off.

Sorry I made an error. The top solar status shows off and the bottom status shows on.
