6.5 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 prior to commissioning, or by configuring the "CntrySet" or "Set country standard"
parameter via a communication product (z. B. Sunny WebBox or Sunny Explorer) once you have
commissioned the inverter.
The switch position 0/0 indicates the state upon delivery. If you have ordered the inverter with specific
country settings, they will have already been preset at the factory via a communication product. In this
case, you will not be able to recognise the current setting by the switch position. If changes are made
via the rotary switches or via a communication product, the default grid parameters are overwritten.
They cannot be restored, and must be re-entered via a communication product. The display language
can be changed at any time using the rotary switches, independent of the grid parameters. This means
that 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 accepted immediately after switching the miniature circuit-breaker on. If a
non-programmed 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 connection conditions demand a mechanism which prevents the feed-in
parameters from being changed. Therefore, some country data sets are 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 after these 10 feed-in
hours, the inverter will not accept the changes and display 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 applied.
