Always disconnect your solar panels first. If you don't have a switch between the panels and the SCC, you can cover the panels with cardboard, or a tarp to block the sun. The battery has a lot of stored energy that can weld things together. The solar panels can supply higher voltages and a decent amperage to shock you. 1.
The battery voltage may always be connected to the SCC. The "12V disconnect" may only disconnect the loads from the battery. The solar could keep on charging the battery when you have disconnected the loads. It does look like you have no power from the solar panels. You will need to follow the wires up to the panels.
Positive lead on the red wire from the solar panel, Negative lead on the black wire from the solar panel. Remember that there needs to be sunlight on the panels to get voltage from them. The battery voltage may always be connected to the SCC. The "12V disconnect" may only disconnect the loads from the battery.

Cracking in the back sheet of the panel can cause moisture ingress and panel failure. Hotspots in cells can lead to burn marks and potential fire hazards. Shattered glass in panels can be caused by hotspots or impacts. Moisture ingress and delamination of back sheets can cause leakage and inverter trips.
Use a multi-meter to measure across the two leads. In sunlight, you should see between 20-18 volts. (this number maybe lower on cloudy days). If you do not see this voltage at this point the next step would be to check your panels and work your way back down to the controller with the multi-meter. Put the meter across the leads of each panel.
