Welcome!  This was and is the webspace of the Joachim Dorfmüller (1935-2018) Project. It is for the most part now seemingly void of its traditional microinverters for solar and battery but actually just in transformation process.

micro: little unit

inverter: a device to enable interaction where there is disharmony

microinverters:  'devicing systems with so much inherent harmony, that there is little (or no) need of inverting and adapting' (that's why these systems live so long)
