The last change (executed via rotary switch or communication product) is always verified and
activated if applicable. Consequently, the switch position may not necessarily show the actual country
setting.
6.5.1 Checking the Country Standard
Make sure that the inverter is set to the installation country.
Before commissioning:
• Check that the country standard of the inverter is correct by comparing the default settings of
the inverter listed on the supplementary sheet provided.
After commissioning:
• Check that the country standard is correct by comparing the display message during
(re-)commissioning (see Section7 "Commissioning", page57).
• Check whether the country standard is correct by tapping the display twice and viewing the
display messages of the start-up phase again.
or
• Check that the country standard is correct using the "SMA grid guard" measuring channel via
a communication product.
The settings of each country data set are specified in the operating parameters. The parameters can
be read using a communication product. The description of the operating parameters is available at
www.SMA-Solar.com in the category "Technical Description" of the respective inverter.
Further information on parameter settings
For detailed information on making adjustments and changing parameters, see the
corresponding user manual for your communication product.
Display language
Once you have set the country standard, you can always set the display language later using
rotary switch B. However, you have to then set rotary switch A to "0" in order to keep the
country data set.
