CO2 Reduction submenu
You can use the carbon dioxide (CO
2
) reduction
factor to calculate how many tonnes of carbon
dioxide emissions would be produced with
conventional electrical energy sources instead of
solar power. The default value is 0.7 t/MWh. If you
set the value to 0, the CO2 reduction header does
not show in the
Energy view.
Traditional electrical energy sources produce
carbon dioxide emissions. Their amount depends
on the local electricity production mix. Ask the carbon dioxide emission data from
your local electrical company or carbon monitoring institute. Solar energy offsets
production from traditional energy sources and reduces carbon dioxide emissions.
Screen submenu
Use the Screen submenu to set the screen
brightness, contrast and screensaver delay.
By default, the display backlight is on when the
inverter operates. When the inverter is in the sleep
mode, the control unit and display are off. The
control unit wakes up and the backlight illuminates
when you use the keypad.
If you do not use the keypad for a preset time, the
Sun view appears.
You can set the Reduced backlight function ON to dim the backlight when the keypad
is not used for a preset time.
