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 volt-
age 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 re-
quired, 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 param-
eter intervenes.
Ni-Test Impulse setting for impedance monitoring. This parameter takes
effect when the Sunny Boy is deactivated (disconnected on the
AC side) or put to "Stopp" mode.
Plimit Upper limit for AC output power
Ripple-Ctl-Frq The Ripple-Ctl-Frq, Ripple-Ctl-Lev, Ripple-Ctl-Rcvr parameters are
intended to handle ripple control signals from the SMA inverters.
These parameters are not available for all inverters. These pa-
rameters may only be changed after prior agreement with
SMA
Technologie AG.
Ripple-Ctl-Lev
Ripple-Ctl-Rcvr
Riso-Min Lower limit of the allowable insulation resistance
SMA-Grid-Guard SMA grid guard version number
SMA-SN Serial number of the Sunny Boy
Speicherfunkt. Default Parameter: Returns all parameter values to the factory
setting.
Reset Betriebsdaten: Returns all user level parameter values to
the factory setting.
Reset Fehler: Resets a permanent fault.
Storage Permanent: Modified parameters are stored in the EEPROM and
can be used even when the Sunny Boy has been restarted.
Volatil: Prevents the parameters being stored in the EEPROM, the
parameters are only stored until the next restart.
T-Start The period the Sunny Boy waits after all switch-on conditions
have been satisfied.
Uac-Min Lower (Uac-Min) and upper (Uac-Max) limits of the allowable
AC voltage (self contained power system recognition), before
the grid monitoring system disconnects the device from the grid.
