Fac-Pderating Frequency-dependent output limitation.
Fac-Start delta For setting the frequency-dependent output derating in the operating
mode "Off Grid". Further information on this topic can be found in
the Sunny Island operating manual.
Fac-Tavg Averaging time of grid frequency measurement.
Fan-Test By setting the "Fan-Test" parameter to "1" you can check
functionality of the fan.
Hardware-BFS Hardware version of the operation control unit (BFR)
h_Total Total hours of operation for the inverter. This change may be
necessary when you exchange your Sunny Mini Central and want
to use the data from the old device.
I-NiTest Setting the impulse for impedance monitoring.
This parameter only functions when the Sunny Mini Central is
deactivated (disconnected on the AC side) or in "Stopp" mode.
Inst.-Code Parameters for grid monitoring can only be changed after entering
the SMA grid guard password.
KI-Wind-Reg Control factors in Turbine mode. Further information on this topic can
be found in the Windy Boy instruction manuals.
KP-Wind-Reg
LDVtgC Compensation for the voltage drop in the cabling.
With this parameter, the voltage drop between the inverter and the
grid connection point is taken into account. The 10-minute average
voltage at the inverter connection must not exceed the sum of
ACVtgRPro plus LDVtgC. The parameter LDVtgC is preset to 0 V for
Germany. In grid areas in which the additional voltage rise
protection (see parameter ACVtgRPro) is not required, the
parameter LDVtgC is preset to 50 V. Thus, the voltage rise protection
is deactivated for these grid areas (253 V + 50 V = 303 V) and only
the fast cut-off via the Uac-Max parameter intervenes.
Plimit Upper limit for AC output power.
Pmax Output limitation of the inverter.
P-Wind-Mid Parameters for adjusting the inverter in Turbine mode. Further
information on this topic can be found in the Windy Boy instruction
manuals.
