Not an answer to any of your questions but I found it interesting that the
micro inverter is often rated lower than the advertised power output of the
panel it is attached to.

The rationale being that bang for buck declines when trying to build a
micro inverter that caters for the rarely seen peak outputs.  Seems
reasonable.
