100/50 MPPT Not displaying any Solar Info in App

I'm pretty new to all of this and cant seem to figure out the issue. I just hooked up my new solar system and the Victron App is not showing any information from the Solar side, no watts or amps. I have 3 150watt panels in parallel into a 100/50 Smart MPPT as well as a BMV 712. Batteries are 2x Battleborn 100ah lithium in parallel 12v. Both the charge controller and BMV have been setup according to battleborn.

I've checked breakers and fuses, all good. I cant figure out what I'm missing here.

Any advice would be greatly appreciated!

@Samso, check the polarity of your PV array connection... a solid 80% of the time that we see this, it's because polarity is reversed going into the MPPT.

Thank you, this was the problem. I rechecked all my connections on the roof and found a few that were the wrong polarity. Lesson Learned: dont install solar late at night with drinking buddies haha
