The display can be operated by pushing and pulling the switch and by using the button
(see section 4 "Operating the Display", page 27). By pushing the switch, you can switch on the
backlight of the display.
3.4 Stop/Start Switch
Use the stop/start switch to switch the Sunny Central on or off.
Switch position "Start"
After turning the stop/start switch to "Start", a motor drive closes the DC contactor and the
Sunny Central goes from the operating state "Stop" to the operating state "Grid monitoring". If there
is sufficient irradiation and a valid power distribution grid connection, the Sunny Central switches to
feed-in operation. If there is insufficient irradiation and, in turn, the input voltage is too low, the
Sunny Central remains in the operating state "Grid monitoring".
