No power from new solar panel

[Damdifino]

I have existing solar wiring in my Casita running through a Renogy ViewStar controller. The controller is communicating with my battery. However, I'm not getting any input from my new 100W Renogy solar panel. Inline fuse is good. What should I look for?

You have power to the controller.

Panel connected to the load terminals? (Tee hee)

test the panel for both voltage )Voc) and amps (Isc).

are you suggesting the panel led is out = 'not getting any input from'?

That could be a issue with the controller.

During the day does battery voltage rise/charge?
Does the LCD indicate any PV voltage or amps?

But your controller says no input?

Put a volt meter across the panel itself, without any connection to the controller.

Maybe a bad or disconnected diode?

So just stick a probe into each lead? (Excuse my ignorance.)

Tilt and aim the panel at the sun near noon, no clouds. Panel Voc about 22v so with heat from sun, you should get about 20v Voc. Switch meter to amps and now get approx. 6 amps Isc. Panel good, so check your wiring.

Get out your voltmeter and start tracing it down. And get rid of that fuse.
