2023 3124KB - Solar not working?

[MichiganTM3124KB]

Hi yall, new to the TM family and loving our camper. Definitely learning a ton..

I can't seem to figure out why my solar panels are not charging the battery. I have the rig set up outside and it is getting full sun, but still nothing is registering on the Go Power solar controller.

I took the battery out and charged it/re-installed. I was able to use the lights for maybe 5 minutes and there was a display on the solar controller but after the 5 minutes, it was back to blank displays and no power.

The battery has a stamp on it of 05/23. I bought the rig in May..

Any thoughts here on what I should do next to get the solar features working again!

Thank you!!
