Charge Controller Shows No Solar Input? Troubleshooter

Sun's out but the controller sees nothing? Work back toward the panels.

Panels make voltage whenever there's light. Treat their cables as live. Work through one question at a time. You can go back or start over whenever you like.

Safety: this troubleshooter is general information. Follow the maker's manuals. Any work on 240V AC wiring, the switchboard, or inside an inverter, isolator or battery cabinet must be done by a licensed electrician or your installer.
