Azimuth The azimuth angle indicates by how many degrees the module surfaces deviate from a south-
ern orientation.
• In the text field, enter the number of degrees by which the module surfaces deviate from
a southern orientation. Enter a negative value (e.g.−20) for a deviation to the east and
a positive value (e.g.20) for a deviation to the west.
• If the module surfaces track the sun automatically, activate the checkbox Tracking.
Tilt angle The tilt angle indicates by how many degrees the module surfaces deviate from the horizon-
tal. In some systems, the module surfaces are optimally aligned according to the latitude. In
Germany, the optimum orientation is 30 degrees from the horizontal.
• In the text field, enter the number of degrees by which the module surfaces deviate from
the horizontal.
• If the module surfaces are optimally aligned according to the latitude, activate the
checkbox Optimized.

Optional, e.g. String A - Orientation to the east
Creating New String
Requirement:
☐ The system must contain at least 1 inverter.
1. Under Configuration > PV system properties select the tab String configuration and then Add string.
2. In the Inverter line, from the drop-down list select an inverter to which the string is to be assigned (see
Section11.1, page50).
You can register the connected strings for all inverters. To initially register the same configuration for all devices,
select Apply for all inverters when adding a string.
3. Enter the string properties (compare table).
4. Select [Accept].
5. Click on [Save].
Accept existing string and edit
Requirement:
☐ At least 1 string must already be configured in your system.
Procedure:
1. Select 1 string or inverter shown in the table on the tab String configuration.
2. In the line of the selected string and the column Copy, select .
