5.5 Setting the Country Standard and Display Language
The inverter can be configured for various countries. This is carried out via the two rotary switches in
the inverter before commissioning or via the configuration of the "CntrySet" or "Set country standard"
parameters via a communication device (z. B. Sunny WebBox or Sunny Explorer) once 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, the default grid parameters are overwritten. They
cannot be restored, but have to be re-entered via a communication device. The display language can
be changed anytime independently of the grid parameters using the rotary switches. In this way, the
default grid parameters remain unchanged, but the display messages are shown in the set language.
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
unprogrammed switch setting is selected, the inverter issues an error message on the display and the
last valid setting is retained.
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 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 via the rotary switches in the inverter, this change is immediately taken on.
