h_Total h 0 ... 200000 0 Installer Total total operating hours of the
inverter. Changing the value can be
necessary when a Sunny Boy is
exchanged and you wish to match
the previously acquired data.

MPP Installer Operating Modes of the Sunny Boy:
MPP-Operation: Sets the Sunny Boy
in Maximum Power Point Tracking
Mode
V-const: Constant Voltage Mode
(Setpoint defined in “Vconst-Setval“)
Turbine: Operating mode for wind
power plants
Stop: Disconnection from utility, no
operation
T-Max-Fan °C 0 ... 100 90 Installer Temperature for maximum fan
rotation speed.
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 60 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 50 Installer Fan turn-off temperature
V-Const Setval V SB 3000US:

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 and upper limits of allowable
AC voltage
Default value is optimal for
installations < 30 kW
Vac-Max* % 0 ... 20 10 Installer
Vac-Min-Fast* % 0 ... 50 50 Installer Values are used to calculate the
lower and upper limits of allowable
AC voltage for fast disconnection.
Default value is optimal for
installations < 30 kW.
