CONFIGURATION
Overview
Sirio Central inverters have a new man-machine interface (MMI) as standard, consisting of a colour
LCD Touch panel. The characteristics and the quantity of information enrich the experience of user
interaction with the solar inverter.
Everything can be done with just a touch.
When the inverter is started up for the first time after commissioning, a screen appears asking you
choose the country where the inverter is installed:
Press the arrows on the right to scroll between the countries currently managed. Once the choice has
been made, simply touch the image of the Earth to proceed with the configuration:
You can confirm or cancel your choice going back to the previous screen.

5
CAUTION: Choosing the country configures the inverter to the values prescribed by
the regulations in force in the country of installation. Once you have made your
choice, you cannot change this setting without contacting Technical Assistance
Service staff. The interface language can still be changed at a later date using the
ADVANCED SETTINGS menu.
The next times the device is turned on, after the welcome AROS logo, the screen will appear as
shown below (the background color may vary according to the inverter operating conditions):
The screen consists of the following main areas:
1. At the top of the screen, the model, date, time and rated power of the inverter are displayed
from left to right.
2. The daily graph showing the power delivered is shown in the middle of the screen. The
horizontal scale represents the hours (from 5 to 22 i.e. 5 am to 10 pm) while the vertical scale
represents the kW. In the top right of the graph is the value of the instantaneous power while
on the left is the energy produced during the current day.
3. At the bottom of the screen is a line providing status information, with messages that alternate
once per second.
4. On the right of the screen, there is a column with buttons that allow you to navigate within the
interface.
After 5 minutes of inactivity, the LCD screen enters screensaver mode. Just tap it to return to normal
viewing. The following symbols may appear on the off screen during daytime:
The first symbol indicates that inverter operation is regular, the second that solar radiation is low and
the third indicates an alarm.

6
The buttons on the right-hand side of the column let the user access the main functions; they have the
following symbols and meanings:

Swiping the finger on the screen from left to right or from right to left it’s possible to see data of
previous/next year
Touching it again returns you to the home page.
Basic interactions
All the features and customizations of the system can be queried using the following actions:
Touch: touching the button or specific area of the screen;
Swipe: moving your finger on the screen while holding it down, from right to left or from left to
right. This may be required to navigate through the daily graphs or between different screens
on some occasions.
Whenever a touch or swipe is recognized, the MMI will confirm with a beep.
For file transfer, a USB flash drive with a single FAT32 partition is required;
otherwise it will be impossible to complete the data saving operation correctly.

Description of the Menu
MEASUREMENTS
From the main window, as seen, you can access the other areas of the interface. In particular, press
the button to consult the inverter measurements:
The synoptic panel shows all the main device measurements.
The two buttons on the right-hand side allow you to view the temperatures measured inside the
inverter and the measurements of the four analogue probes if connected.
By pressing the Temperature button accesses the following screen.
If a DC-BOX is present that monitors the current for each individual input
(and suitably configured), pressing the button allows for viewing the current readings for
each input.

9
In this window it is possible to change the ‘weight’ parameter for each input in relation to the
photovoltaic panels supplied, by pressing the relative ‘%’ key located beneath each reading.
For example: if inputs 1, 2, 3, 5, 6, 7 and 8 have a rated current of 180 A while input 4 has a rated
current of 140 A, the relevant settings are:
%1 = 100% - %2 = 100% - %3 = 100% - %5 = 100% - %6 = 100% - %7 = 100% - %8 = 100%;
%4 = 140/180*100 = 77.7 78%
See the next screen.
Press the ‘%’ key to access the following screen where the weight of the single string (in this example,
78) can be set through the + / –buttons.
NOTE:
in the event that not all of the 8 inputs are used, the free input reading must be deactivated. Press the
‘%’ key corresponding to the free input and set the ‘weight’ to zero.

10
By pressing the analogue probes accesses the following screen.
The button is used to return to previous windows, this button is available in all windows.

HISTORICAL DATA
The button allows you to access the screens for managing the historical inverter data:
1 view LOGS
2 save LOGS
3 delete LOGS
4 save SYS LOGS
5 save total LOGS
To view the logs, press the button with the symbol. Then select the measurements to be
displayed (only two measures can be displayed at the same time):
To select a measurement, press the corresponding button.
A white tick will appear on a green background to highlight the choice.
If you want to deselect an item, simply press the button again.
To proceed with reading of graphs, press button

Now you can :
Go ahead and back one day with a simple touch: scrolling across the screen from right to left
and from left to right respectively
With the lens button to enlarge the graph.
Send graphic via email (the button appears only if the service is configured).
Select the day you wish to view from the calendar
The units of measurement appear at the bottom. The horizontal axis is always temporal in the time
range [5 - 22]. The vertical axis on the left has the left-hand unit of measurement and the one on the
right has the right-hand unit of measurement. The curves always have different colours.
To save the historical data on a USB flash drive, press the button with the symbol. The
following window appears:
As already mentioned, the USB flash drive must be FAT32 (VFAT) formatted and have a single
partition. Many USB flash drives that have dedicated protection software with special partitioning
schemes may not work.
