is less than the permissible value. The inverter must not switch onto the
grid.
Contact your installer.
Invalid country
setting
One or more inverters have an invalid country code. Either no country was
selected during commissioning or differing countries are selected for multiple inverters in the same system. The inverter(s) do not feed into the grid.
Set the correct country code for all inverters as described above.
DC input voltage
too high
The input voltage at the inverter exceeds the permissible value. The inverter
does not feed into the grid.
Switch off the main DC switch of the inverter

11.1.4 Remote display error messages
W: <XX>% below average daily yield
The test for low yields takes place at midnight (0:00 hours) each day. The following applies:
• The daily yield of each inverter is compared to the average daily yield of all inverters.
• An alarm is triggered if an inverter has a yield greater than 0.001 Wh but less than
the defined threshold value.
• <XX> is the percentage value that the inverter yield is below the average yield.
Example:
If an inverter only delivers 75 % of the average daily yield then <XX> has a value of
25 %.
E: 24 h no RS485 communication
The remote display has not been able to communicate with the inverters for more than
24 hours.
E: Shutdown refused
The inverter has refused to obey a shutdown command. The command is generated if a
conflict occurs when setting the country.
E: Country setting refused
The inverter has refused to obey a command to set the country.
Contact your installer.
W: Derating refused
The inverter has refused to obey a command to reduce the output power.
11.2 Settings screens
EN
11.2.1 Language
The language setting is queried during initial commissioning and after an error has been
detected in the internal device storage, see Section 7, p. 36 onwards.
11.2.2 Time & date
The date and time must be manually set by following a guided setting procedure when:
• The device is first commissioned.
• A fault occurs in the internal device storage.
• The device has been without power for more than 2 days.
If the user has not updated the date and time then the remote display updates its internal clock by comparing it with the date and time values of the inverters.
Note
52
The remote display queries date and time values from the inverters between 4:00 and
12:00 hours and compares these with its own internal clock. The following applies:
• Iftheinverterandremotedisplayvaluesdeviateby≤1minutethenallvalues
remain unchanged.
• If the inverter and remote display values deviate by > 1 minute then the remote
display adopts the average value and sets all other inverters to the same value.

11.2.3 Address setting
The addressing is queried during initial commissioning and when an error occurs in the
device internal storage; see Section 7, p. 36 onwards.
11.2.4 Country setting
If settings are changed in the inverters, in some cases it may be necessary to set the
country again; see Section 7, p. 36 onwards.
Set country
This message means that the country has not been set
in any of the inverters and these are all running with
their default values. This is typically the case during
initial commissioning.
The displayed country selection list in English shows all
countries whose settings are supported by all inverters.
Select the correct country where your system is
installed.
Set country: No country available for all inverters
This message means that at least two inverters do not
support the same country and cannot feed into the
mains grid for legal reasons. Example:
• Inverter 1 supports Germany, Spain and Portugal.
• Inverter 2 supports France, Italy and Austria.
This message remains displayed until the incompatible
inverter is replaced.
734.144 | Z04 | 2012-11-22
Contact your installer.
Colliding country codes: System shutdown
This message means that at least two inverters are
set to different countries and cannot feed the mains
grid for legal reasons. This is typically the case when a
system contains inverters that were previously used in
other countries.
The country selection displays the set countries in
English: Example:
• Inverter 1 is set to France.
• Inverter 2 is set to Germany.
If a third inverter with Spain set as the country is also
present then Spain will also be displayed.
