Guessing @kevin1 might have a solve for you but my general take is that any solar dropouts are going to be very interesting to the Sense team and contacting support should get you some quick action.
Solar dropouts = Emergency status!
A thought for the team: Where is the alert for @erik?
This is potentially something that should be bumped to the top of the support list.
Edit: Open circuit degradation is something you really need to stay on top of …
