5.3.1 SMA Grid Guard Protected Country Data Sets
In some countries, the local power supply line requirements demand a mechanism which prevents the
parameters for grid feeding from being able to be changed. Some country data sets are therefore
protected and can only be unlocked with a personal access code, the so-called
SMA Grid Guard code.
SMA Grid Guard protected country data sets are automatically blocked for 10 feed-in hours after
commissioning, or after the last alteration. If the country data set is changed via the rotary switch after
these 10 feed-in hours, the inverter will not accept the changes and displays the error message
"Grid parameter locked". If,however, a later change to the country data set only relates to a change
of the display language, this change is immediately taken on.
It is also possible via a communication device to configure ("CntrySet" or "Set country standard") as
well as to manually block or unblock country data sets. To lock, you have to set the so-called
SMA Grid Guard code to "54321". This will automatically appear as an input window when
changing the first grid-relevant parameter. 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.
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".
Detailed 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.
The last change (executed via rotary switch or communication device) is always verified and activated
if applicable. This means that you can not always read off the actual country setting from the switch
position.
