5.1.1 Country setting via rotary switch
The switch position 0 / 0 indicates the factory setting. If you have ordered the Sunny Boy with a
certain country or grid setting, the setting is done in the factory via a communication device. The
setting will be overwritten by changes to the rotary switch or via a communication device and can not
be recovered. For orders without a specified installation country or grid type the standard setting is
”US auto” with display language ”German”.
Changes to configuration will immediately be accepted after switching on the line circuit breaker.
If an un-programmed switch setting is selected, the Sunny Boy issues an error message.
• Check whether the Sunny Boy is set to the installation country and grid type using the listed
switch settings in the following table.
• For display language in English set the switch (B) to position "1".
Rotary switch positions
The operating parameters show the corresponding parameter set. You can read these off via a
communication device or download them from www.SMA‑America.com.
Display Language
Once you have configured the country data set, you can set the display language later
without changing the country data set using rotary switch (B).
