10 Parameters
Note the following when setting parameters:
• Observe the operating data of the solar components used.
• The individual parameters are only displayed and can be changed when this is per-
mitted by the type of solar system that has been set.
Special case: System 0.1 has no parameters, no P is displayed.
• In most applications the controller can be used without modifying any parameters.
More information is provided in the Functionality column.
The figures in this section show examples.
