Installer PV Setpoint voltage for constant
voltage operation. These
parameters only are important in
case the parameter “Operating
Mode“ is set to “V-const“.
Vac-Min* % 0 ... 50 12 Installer Values are used to calculate the
lower limit of allowable AC voltage.
Default value is optimal for
installations < 30 kW. The default
12 results in a trip value of 88 % as
listed under trip limits.
Vac-Max* % 0 ... 20 10 Installer Values are used to calculate the
upper limit of allowable AC voltage.
Default value is optimal for
installations < 30 kW. The default
10 results in a trip value of 110 % as
listed under trip limits.
Vac-Min-Fast* % 0 ... 50 50 Installer Values are used to calculate the
lower limit of allowable AC voltage
for fast disconnection. Default value
is optimal for installations < 30 kW.
The default 50 results in a trip value
of 50 % as listed under trip limits.
Vac-Max-Fast* % 0 ... 20 20 Installer Values are used to calculate the
upper limit of allowable AC voltage
for fast disconnection. Default value
is optimal for installations < 30 kW.
The default 20 results in a trip value
of 120 % as listed under trip limits.
Vac-Min-Recnet % 0 ... 50 11.7 Installer Values are used to calculate the
lower and upper limits to reconnect
to the grid after a grid frailure.
