Ripple-Ctl-Frq The Ripple-Ctl-Frq, Ripple-Ctl-Lev, Ripple-Ctl-Rcvr parameters are
intended to handle ripple control signals from the Sunny Mini
Centrals. These parameters are not available for all Sunny Mini
Centrals. These parameters may only be changed after prior
agreement with SMA Technologie AG.
Ripple-Ctl-Lev
Ripple-Ctl-Rcvr
SMA-SN Serial number of the Sunny Mini Central.
Software-BFR Firmware version of the operation control unit (BFR).
Software-SRR Firmware version of the current control unit (SRR).
Speicherfkt. • Default Parameter: returns all parameters to the factory
settings.
• Reset Betriebsdaten: returns all user level parameters to the
factory settings.
• Reset Fehler: resets a permanent error.
Speicher/
Storage
• Permanent: modified parameters are stored in the EEPROM
and can be used even when the Sunny Mini Central has been
restarted.
• Volatil: prevents the parameters being stored in the EEPROM,
the parameters are only stored until the next restart.
T-Max-Fan Temperature for the maximum fan speed.
T-Start The period the Sunny Mini Central waits after the Upv-Start value
has been reached.
T-Start-Fan The fan starts to run at minimum speed at this temperature.
T-Stop The period the Sunny Mini Central waits before disconnecting from
the grid when Upv drops below the grid peak voltage.
T-Stop-Fan If after a temperature increase the inverter cools down to below this
threshold value, the fan switches itself off again.
Uac-Max Lower (Uac-Min) and upper (Uac-Max) limits of the allowable AC
voltage (stand-alone grid recognition), before the grid monitoring
system disconnects the device from the grid.
Uac-Min
Uac-Tavg Averaging time for measuring grid frequency.
Udc-WindMax Parameters for adjusting the inverter in Turbine mode. Further
information on this topic can be found in the Windy Boy instruction
manuals.
Udc-WindMid
Udc-WindStart
Upv-Start The DC voltage required before the Sunny Mini Central begins
feeding power into the grid.
