Functional principle Functional prin- The inverter operates fully automatically. As soon after sunrise as there is sufficient en- ciple ergy available from the solar modules, the inverter starts checking the PV system (insu- lation measurement), and the grid (grid voltage and grid frequency). If all values are with- in the normative scope, automatic connection to the grid and feeding of energy into the grid takes place.
