5.5 Setting the Country Standard and Display Language
The inverter can be configured for various countries. This can be done via two rotary switches in the
inverter prior to commissioning or by configuring the "CntrySet" and / or "Set country standard"
parameter using a communication device (e.g. Sunny WebBox or Sunny Explorer) after you have
commissioned the inverter.
The switch position 0 / 0 indicates the delivered state. If you have ordered the inverter with specific
country settings, these will have already been preset in the factory via a communication device. In this
case, you will not be able to recognize the setting by the switch position. If changes are made via the
rotary switches or via a communication device, these settings will be overwritten and cannot be easily
restored. For devices ordered without any specified country of installation, the standard setting is
"VDE0126-1-1" and the language is German.
Changes will be immediately accepted after switching the line circuit breaker on. If an
un‑programmed switch setting is selected, the inverter issues an error message.
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.
Country data sets protected by Grid Guards are blocked automatically 10 feed-in hours after
commissioning or the last modification. If the country data set is changed 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 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 set the 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.
