Did you follow the suggestions from the app.

Like checking voltage from panels with a meter etc. The usual fuses and breakers problem, or loose mC4 connections?

Yes, I checked the 3 suggestions from the APP. I checked the 4 strings voltages at the MPPT inputs. also I checked the battery voltage.

Thank you

Is the app reading any voltage there from the PV? If it isnt you may need to take it in for a warranty repair

Any internal PV fusing or protection?
