dFac-Max Maximum "grid frequency change" before the grid monitoring
system disconnects the device from the grid.
dZac-Max Maximum "grid impedance change" before the grid monitoring
system disconnects the device from the grid.
E_Total Total energy yield for the inverter. This change may be
necessary when you exchange the Sunny Boy and want to use
the data from the old device.
Fac-delta-
Fac-delta+ Maximum frequency, above (Fac-delta+) and below (Fac-delta-)
the mains frequency, before the mains monitoring system
disconnects the device from the mains supply.
Fac-Pderating Frequency-dependent output limitation
Fac-Tavg Averaging time of grid frequency gaging
h_Total Total hours of operation for the inverter. This change may be
necessary when you exchange the Sunny Boy and want to use
the data from the old device.
I-Ni-Test Setting the impulse for impedance monitoring. This parameter
only functions when the Sunny Boy is deactivated (disconnected
on the AC side) or in "Stopp" mode.
Inst.-Code Parameters for self contained power system recognition can only
be changed after entering the "SMA grid guard" password.
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 average
voltage over 10 minutes 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 surge voltage protection (see parameter ACVtgRPro)
is not required, the parameter LDVtgC is preset to 50 V. Thus, the
surge voltage 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.
