SUNNY ISLAND 5048 - Technical Description - Wind & Sun Ltd.

Operation SMA Solar Technology AG
10 Operation
The main menu consists of a "Home Screen" and the other main menu entries, which split up into the
different menu levels. Operating states, for example, the current operating mode, power, etc. are
displayed on the "Home Screen" (see section 10.6 ”Display Messages (Overview)” (page 77)).
The menu consists of a main menu and maximum two sub-menu levels (see section 10.1 ”Menu
Structure” (page 67)).
Use the up and down arrow buttons to navigate through the menu levels. The cyclical arrangement
(wrap around) allows you to scroll both forward and backwards to access the desired menu as
quickly as possible.
Faster access to menus
If you would like to access submenu "7", navigate backwards from "1" over "9", instead of
six steps forwards.
When the desired menu is reached press the key in order to access it. The key exits
the menu and puts you one menu level up.
Switching to the Home Screen in case of inactivity
If you do not press any buttons for more than five minutes (inactivity), the Home Screen is
automatically displayed.
Background illumination
The display's background illumination is automatically deactivated after a short time of
inactivity. You can switch the background illumination back on by pressing one of the four
buttons. No settings are changed when you press the button, this only activates the display
illumination.
Acoustic button sounds
If "250.04 BeepEna" is set to "off", the Sunny Island does not alert faults and errors with
an acoustic warning signal.
Slaves wait for commands from the master
Slave devices must wait for commands from
the master devices. The following message
appears during this time.
The Sunny Island utilizes an operation concept referred to as "Single Point of Operation". For a
system with more than one Sunny Island, all entries are made on the master. There you configure the
entire system, confirm events, warnings and errors in the QCG (see section 8 ”Initial Start-up”
(page 56)), and update your firmware when required (see section 11.6 ”Updating the Firmware”
(page 89)).
Exception: When starting the device for the first time, you must set the slave devices as slave in the
QCG and everything else is performed at the master.
