84 SB50US-80US-IUS094030 Installation Guide
The following parameters appear in parameter list but cannot be modified:
T-Start s 5 ... 1600 10 Installer The time the inverter waits to connect
to the grid after Vpv-Start is
exceeded.
This value defaults to 5 minutes after
a utility fault.
T-Start-Fan °C 0 ... 100 70 Installer Fan turn-on temperature at minimum
rotating speed.
T-Stop s 1 ... 1800 2 Installer The time that the Sunny Boy waits to
disconnect from the grid when Pac
falls below minimum necessary Vpv.
T-Stop-Fan °C 0 ... 100 55 Installer Fan turn-off temperature

600 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 installa-
tions < 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 volt-
age 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.
Vac-Max-Recnet % 0 ... 20 5.83 Installer
