11 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 energy 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.
