PV target voltage for constant
voltage operation. These
parameters only are important in the
event that the parameter "Operating
Mode" is set to "V-const".

Values are used to calculate the
lower limit of permissible AC
voltage.
Standard value is optimal for plants
< 30 kW. Standard value 12 results
in a trip value of 88 %, as the list of
trip limits shows.
Vac-Max* % 0 ... 20 10 Electrically
qualified
person
Values are used to calculate the
upper limit of permissible AC
voltage.
Standard value is optimal for plants
< 30 kW. Standard value 10 results
in a trip value of 110 %, as the list of
trip limits shows.
Vac-Min-Fast* % 0 ... 50 50 Electrically
qualified
person
Values are used to calculate the
lower limit of allowable AC voltage
for fast disconnection. Standard
value is optimal for plants < 30 kW.
Standard value 50 results in a trip
value of 50 %, as the list of trip limits
shows.
Vac-Max-Fast* % 0 ... 20 20 Electrically
qualified
person
Values are used to calculate the
upper limit of allowable AC voltage
for fast disconnection. Standard
value is optimal for plants < 30 kW.
Standard value 20 results in a trip
value of 120 %, as the list of trip
limits shows.

Values are used to calculate the
lower and upper limits to reconnect
to the grid after a grid failure.
