Solar not producing

[Teblues]

I checked the voltage the solar panel was producing at the charge controller, and there was not any voltage. It is a 100 watt panel on a clear day and clean. Bad wires, bad panel?????

Check the panel with nothing hooked up. If I remember it will be around 20 volts for a 12 volt panel.

Then hook up wires and disconnect them from the controller and make sure the voltage is getting to the controller.

Thanks. Will try.

Bad charge controller. When I disconnected the battery wires from the controller I got just under 20 volts input from the panel, but only 8.3 volts going out to batteries. Know wonder they were not getting charged.
