Hello friends, I need some help trouble shooting my solar. Quick back round;

Wife and I set up our new Reflection about 3 weeks ago at our property. Everything worked great. The solar was charging, maintained between 11.5-12.3 volts on the panel, the % stayed about 88 or so.It would drain down and charge back up to 100% so I know it was operating correctly. It ran our entire RV for 3 full days with no issues.
While closing up camp (we leave the RV at the property but close up the slides and awnings) the solar system drained to the point of not being able to suck in the slides. I fired up the generator and finished the job. I figured we just drained the battery and it would charge back up. I was also wondering why my two deep cycle batteries didn't take over...

Fast forward to last weekend. I assumed it would be all charged up and ready. Nope. The battery % was at zero and the volt meter at 8.3. I checked the inverter, it is flashing green light like the manual says it should and its a solid orange light showing lithium.(?)
I looked at the fuses, there is nothing labelled anything to do with the solar. I assumed I popped a fuse when I put a heavy load on it closing the slides. The 110 breakers are not tripped either.

What else could this be? It is a royal pain to hook up and bring it back to town to have it looked at. Our property is almost 80 miles from the nearest town with a service center.
I called a GD dealership today, they are not excepting new clients due to lack of technicians available.
They recommended me to ask GD warranty department to authorize a mobile service tech to come out to our property.
Thoughts?
