Technical description
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 67), and perform firmware updates when required (see Section 11.6 "Updating the
Firmware", page 99).
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 from the master.
10.1 Menu Structure
The navigation area includes the "Home Screen" and the main menu items:
• 100# Meters (display values)
• 200# Settings
• 300# Diagnosis
• 400# Failure/Event (lists)
• 500# Operation (operating functions)
• 600# Direct Access
The main menus are divided into several sub-menus.
In a sub-menu, you can select a second sub-menu or a parameter.
You can access the navigation area from one of two levels:
• User level
• Installer level (password required)
Single Point of Operation
Single Point of Operation also means that all master log data, including the slave log data,
is saved at the master device on the SD card.
Messages
Messages can be displayed at any time while the device is in operation and they have priority
over the "Home Screen" display.
Entering incorrect parameters endangers operational safety. Damage to the off-grid system and its
components.
All parameter settings which could affect the operating safety of the off-grid system are protected
by the installer password.
The menu items and parameters in which system parameters can be changed are accessible after
entering the installer password (see Section 10.5 "Entering the Installer Password", page 86).
• Only electrically qualified persons are permitted to set and adjust system parameters.
