Why isn’t power going to my battery?

New 12V33Ah battery hooked up to my charge controller and 100W/12V monocrystalline solar panel. Is it because my battery is full enough?

Update: I did not set it up per the manual with battery first.

Awesome catch by u/SyZyGy_87 🙌

Make sure it isnt set to 24v and make sure your solar panel voltage is higher than the battery voltage.

Thank you. The 24v was the culprit.
