  • Page 16: Functional Principle

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