Question about the output from my DIY Solar
So I could use a "shove in the right direction." My Solar is all DIY. Two 100 watt panels, an EPEver 30A MPPT controller. One group 27 (for now). It's working. It's keeping the battery charged. ...

Sounds like only one panel is working. The controller will dial back the charge rate as needed. I don't know if your controller shows what's coming in from the panels.. that would be a clue.
I've had two panels fail in 15 years. They show burnt spots, black or brown, on the front of the panel. They're the aluminum ribbons that connect the cells together. They get hot, so you want want to check for hot spots.
You can check each panel with a voltmeter, or, temporarily wire in series to see if the voltage doubles.
