Explanation of
footnotes
1) The values stated are defaults; the inverter is configured specifically to
suit the requirements of the relevant country.
2) Depending on the country setup or device-specific settings
(ind. = inductive; cap. = capacitive).
3) Maximum current from a defective PV module to all other PV modules.
From the inverter itself to the PV side of the inverter, it is 0 A.
4) Guaranteed by the electrical configuration of the inverter.
5) For backup power mode (PV Point) without battery, a minimum voltage of
150 V is required.
6) Current peak when switching on the inverter.
