On lower end and mid SCCs if the moon symbol is displayed the panels are not connected to the SCC properly (polarity) or are defective.
The moon means no VOC is detected. My panels are ~38.x VOC and roughly 20 minutes before sunup the SCC was displaying 39.x volts and zero amps. Most panels will detect light (show voltage) long before they put out any amperage.
What SCC is it?
Try one panel alone, then the other? Check polarity? Insure you get volts from both panels with a vom?
All those things will eliminate various potential faults so you can fix it. It seems very unlikely but is possible your SCCs are dysfunctional but I would guess it’s other stuff that’s wrong.
