5.3.1 SMA Grid Guard Protected Country Data Sets
In some countries, the local grid connection requirements demand a mechanism which prevents the
parameters for the grid feed‑in from being changed. Some country data sets are therefore protected
and can only be unlocked with a personal access code, the 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 applied.
It is also possible to set country data sets (parameter "CntrySet" or "Set country standard"), and to lock
or unlock these manually via a communication product. To lock a data set, 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 feed‑in 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 can be configured
without a password, regardless of the country data set.
The last change (executed via rotary switch or communication product) is always verified and
activated if applicable. This means that you cannot always read off the actual country setting from the
switch position.
Changing 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 feed‑in 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
You will find information on making adjustments and changing parameters in the
corresponding user manual for your software.
