LCD display
A graphics-capable, monochrome dot matrix display
is integrated in the operating field. In standard
operation the momentary output, daily yield and
status are displayed. The bar graph shows the
energy feed-in of the current day.
Press any key to activate the display lighting. If no
key is pressed for approx. 1 minute, the display
lighting goes out.
Important!
The LCD display is not a calibrated measuring device.
It is characterised by a slight, system-dependent
difference of a few percent. Exact accounting of
the data with the power supply company requires a
calibrated meter.
Keyboard
The keyboard can be used to navigate in the menu,
edit text fields, select entries from lists and enter
numbers consecutively and digit by digit. User
entries can only be made if the value to be changed
is selected. The cursor changes visibly in the editing
mode and indicates the digit to be changed.
