It is also possible to set country data sets (parameter "CntrySet" and/or "Set country standard"), and
to lock or unlock these manually via a communication device. To lock, you have to enter the digit
sequence "54321" instead of the password into the SMA Grid Guard Code field. The data set can
only be unlocked by entering a personal, 10-digit SMA Grid Guard Code which is valid for a
maximum of 10 grid-feed hours. The application form for the personal access code is located in the
download area at www.SMA.de/en, in the "Certificate" category for each inverter. The language is
configurable without a password independent of the country data set.
The last change (executed via rotary switch or communication device) is always verified and activated
if applicable. Consequently, the switch position may not necessarily show the actual country
configuration.
Changing of parameters in SMA Grid Guard protected country data sets
If the parameters within protected country data sets are changed, these are no longer
protected and instead of the standard, "ADJ" or "Special setting" is displayed. In this case,
the parameters are not changed automatically after 10 grid-feed hours, but have to be
manually locked. To manually lock the parameters, set the SMA Grid Guard Code to
"54321".
Further information on parameter settings
Detailed information on how to proceed with respect to setting and changing parameters
is available in the respective User Manual for your software.
