GVDPR - Func-
GVDPR = Gradual Voltage Dependent Power Reduction
tion description
To largely prevent the inverter being switched off when the grid voltage is too high due to
the requirements of various standards and directives, the GVDPR function can be used
to slightly reduce the feed-in power in accordance with the highest phase voltage.
This makes the yield losses less than they would be if the inverter was completely
switched off.
