Explanation of
footnotes 1) The values stated are defaults; the inverter is configured specifically to suit the re-
quirements of the relevant country.
2) Depending on the country setup or device-specific settings
(ind. = inductive; cap. = capacitive)
3) PCC = interface to the public grid
4) Maximum current from the inverter to the solar module when an error occurs in the
inverter
5) Guaranteed by the electrical configuration of the inverter
6) Current peak when switching on the inverter
