Welcome!  This was the webspace of the Joachim Dorfmüller (1935-2018) Project comprising traditional microinverters for solar and battery. Here is what we learned:

micro: a small unit
inverter: a device used when systems do not naturally fit together

microinverters: designing systems that fit together so naturally that little — or no — inversion is required

In the meanwhile we are playing table tennis..  : )   Welcome and Enjoy
