1 INTRODUCTION
This document contains the technical description of the PVI-DESKTOP. The user will
find all the information needed for configuration and for the proper operation and use
of the device.
1.1 AURORA INVERTERS
The inverters for the Aurora range photovoltaic and wind plants are equipped with
internal software that allows several parameters to be monitored for both the operation
of the plant and the inverter itself and for the production of measured energy. The
inverters are also provided with a display (liquid crystal or monochrome) capable of
showing sensitive data simply by using the built-in keypad.
Often, due to the limited accessibility of the system, remote display of all data
recorded by the inverter is necessary so as to have full control of the conversion
device's functions and, at the same, to check the actual energy production.
1.2 PVI-DESKTOP
The PVI-DESKTOP can fulfil the tasks of monitoring and remotely displaying
important parameters. The PVI-DESKTOP is a device which can communicate
remotely with the inverters in different ways, present the information of interest to the
user on a large TFT display, process and store a wealth of information covering the
whole life of the photovoltaic or wind system. As well as all this, the PVI-DESKTOP
can also communicate with other devices (e.g. normal home PCs) via a USB port and,
optionally, via Bluetooth®; this type of communication is possible by using dedicated
software for monitoring the Aurora inverters through a connection with a PC, Aurora
Communicator, which is always included in the inverter package CD and upgradeable
from the web site http:\\www.power-one.com\.
The PVI-DESKTOP thus allows you to replace or supplement the display of data
carried out remotely via the cable between the inverter RS485 port and an input port
on a normal home PC (and which still requires the software mentioned above). The
main advantage of using a PVI-DESKTOP lies in the possibility of setting up wireless
communication and the absence of wired communication. Moreover the large TFT
touch screen display allows the data acquired by the system to be easily and intuitively
displayed and processed. This way the use of an external PC is not strictly necessary.
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
Connection to an external PC is only necessary for upgrading the internal firmware or
downloading the data collected by using Aurora Communicator.
Figure 1 shows a diagram summarizing the connections possible with the PVIDESKTOP, both to the inverters and a traditional PC.

3 GETTING STARTED
WARNING: the PVI-DESKTOP requires some preliminary steps at the
initial start up of the system. Follow the instructions carefully for proper start
up.
3.1 FIRST RECHARGE OF THE BATTERY
The lithium battery inside the PVI-DESKTOP may not be completely charged, or even
completely discharged, at the time of initial start up. To avoid problems, it is
recommended that the object be charged for no more than 10 hours using the
appropriate power supply supplied. Charging is also possible via the USB port, even
when the object is completely turned off, but this takes slightly longer. The LED
indicating the charge will remain orange for the duration of the recharge turning green
once it is fully charged.
WARNING: Should recharging not be complete after 10 hours, unplug the
power supply, check that there is no overheating or deformation in the back
part of the object that would indicate potential damage to the internal battery.
NOTE: Charging via the USB port is slower than charging via external
power supply.
The PVI-DESKTOP can also be used with the power supply always connected.
Leaving the object always connected to the mains causes no problem to its operation
or to the battery. Nevertheless, it is recommended that a full charging and discharging
cycle of the battery be carried out every 2 months.
3.2 SELECTION OF INSTALLATION LOCATION
The PVI-DESKTOP can simply be placed on a flat surface or desk, or can be wall
mounted. This is possible thanks to the docking station with supporting feet and
preruptures for the fixing holes.
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
3.2.1 Wall mounting
Choosing the location carefully for wall mounting is essential for comfortable and
easy reading of data. It is recommended the PVI-DESKTOP is not installed above or
near heat sources (e.g. radiators, stoves or other sources of heat) to avoid damage to
the object. Avoid installing the object in the vicinity of large metallic parts (e.g.
boilers, steel doors, various kinds of metal boxes, etc.) in order not to limit the
operating efficiency of radio communication or Bluetooth®. It is furthermore
recommended that areas where the incidence of direct light may make it impossible to
read the display correctly and even lead to discolouration of the external plastic are
avoided. The following figures illustrate the procedure for proper wall mounting.
Figure 4 - Wall mounting procedure
Drill two holes, diameter 5 mm and minimum depth 45 mm, 3 cm apart from each
other (Figure 4.a.). Insert the dowels (Figure 4.b.). Screw the base to the wall using the
screws provided (Figure 4.c.)
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
The PVI-DESKTOP support base is designed to make it easy to remove the object
even with the power or communication cables inserted. Moreover, if properly
installed, the PVI-DESKTOP will be perfectly parallel to the wall chosen.
NOTE: The physical characteristics of the installation location (wall
thickness, presence of metal or glass walls, distance from the Aurora inverter,
etc.) may limit the range of the radio signal. It is recommended that, once a
plausible location for mounting has been identified, a radio communication
test is carried out before the actual installation.
3.2.2 Installation on desk
The PVI-DESKTOP base enables comfortable and solid positioning on flat surfaces
such as tables or desks. The inclination of about 10° of the axis allows for easier
reading of the display and more convenient use of the touch screen. It is recommended
the PVI-DESKTOP is not installed above or near heat sources (e.g. radiators, stoves or
other sources of heat) to avoid damage to the object. Avoid installing the object in the
vicinity of large metallic parts (e.g. boilers, steel doors, various kinds of metal boxes,
etc.) in order not to limit the operating efficiency of radio communication or
Bluetooth®. It is furthermore recommended that areas where the incidence of direct
light may make it impossible to read the display correctly and even lead to
discolouration of the external plastic are avoided.
NOTE: The physical characteristics of the installation location (wall
thickness, presence of metal or glass walls, distance from the Aurora inverter,
etc.) may limit the range of the radio signal. It is recommended that, once a
plausible location for mounting has been identified, a radio communication
test is carried out before the actual installation.
3.2.3 Tips on the selection of installation location
The selection of installation location and the position of the PVI-DESKTOP strongly
influence the quality of the radio signal received. Choosing to leave the PVIDESKTOP resting on a desk free of obstacles and objects in a 20 cm radius allows the
best radio signal reception. If you choose wall mounting, take into account some rules
that allow data reception to be much improved. Avoid, for example, installing the PVI-
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
DESKTOP on walls coming between the inverter and the controller, and prefer walls
which do not come between the line of communication (Figure 5).
Figure 5 - Wall mounting, selection of location
Keep metal or conductive objects as far away as possible.
Signal quality is also influenced by environmental factors such as fog, rain, air
humidity, etc. The effect of these environmental factors is negligible over limited
distances but can be considerable over long communication distances.
3.2.4 Radio communication test
To test communication, it is possible to carry out a simple plant configuration as
shown in paragraph 4 point 2). Appearance of your inverter in the list of associable
devices is confirmation radio signal reception.
3.3 OTHER PRELIMINARY OPERATIONS
Before starting up the PVI-DESKTOP for the first time, make sure the Aurora
inverters have been properly configured. Check that the PVI-RADIOMODULE card
has been installed in the Aurora inverters, should activation of radio communication
with the PVI-DESKTOP be desired. To install the PVI-RADIOMODULE reference
should be made to the applicable manual. Check that the cable is long enough for
RS485 communication, if you desire to use wired configuration as an alternative to
radio communication.
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
WARNING: Connector 7. Figure 2 is reserved for use with special wiring
for RS485 communication with Aurora inverters. Under no circumstances
connect with any other device (Ethernet, telephone network or other) as it
could lead to possible damage.
Check that the SD card is inserted correctly before turning on the device. The SD card
is an integral part of the device and is absolutely necessary for its operation. Missing
or incorrect insertion of the SD card generates an easily recognizable error message on
the display.
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
4 SYSTEM INSTALLATION
When all the preliminary steps (see § 3) have been carried out, the initial start up of
the communication system can proceed. For proper initial start up follow the
operations indicated in the following paragraphs scrupulously.
1) Inverter configuration and device switch on
• Check that the PVI-RADIOMODULE is correctly installed (see the PVI-
RADIOMODULE manual) if you want to initialize radio communication.
• Check that the Aurora inverters in your photovoltaic/wind plant are turned on.
• Check that the addresses for the RS485 ports are all different (they do not
need to be sequential).
• Check that the RS485 wiring is correct and inserted if you want to initialize
RS485 cable communication.
2) Switching on the PVI-DESKTOP and inverter association
• Switch on the device by pressing the ON/OFF button and follow the
instructions that appear on the display, select the desired values and click on
next.
• Set the date and current time.
Please note that you can change the setting at any time through the "Settings Date - Time" menu.
• Select the communication channel: select the box corresponding to the
communication channel that will be used (Radio or RS485).
• Select the number of inverters that will be connected to the PVI-DESKTOP
(from 1 to 6).
• Select how often you want a data read refresh. The time is selectable from a
minimum of 1 minute to a maximum of 15 minutes.
•
Scan the communication channel to search for inverters or choose to defer the
operation to a later time.
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
• If you decide to carry out the scan, the PVI-DESKTOP will begin to
interrogate the various addresses until has found a number of inverters
corresponding to the one set in the configuration process. During scanning, a
screen showing a table with an indication of the state of scanning will appear.
• At the end of scanning, the table will show the models and serial numbers of
the inverters found.
• At this point it is possible to choose which inverter(s) to associate uniquely
with your PVI-DESKTOP so that they cannot be seen and recognised by
other PVI-DESKTOPs nearby. The selection is made by pressing the '+' key
next to each inverter chosen. Pressing the '+' key changes the colour of the
corresponding row in the table by highlighting the selection.
• It is advisable to check that the serial numbers of the inverters chosen
correspond to those of the inverters in your system to avoid associating
inverters from other systems nearby with your PVI-DESKTOP.
• At this point the system is configured and, automatically, starts the
synchronization procedure for the timetable of the monitored inverters and
data acquisition from the inverters. The first synchronization can also take a
very long time because of the high amount of historical data that the inverters
will send to the PVI-DESKTOP.
• On the other hand, if the channel scan is unsuccessful, an error message and a
request to repeat the scan will be displayed.
• To determine the causes of non-recognition of the inverters, consult the
troubleshooting guide attached to the manual
3) Inverter disassociation or need for reconfiguration
Whenever it may be necessary to delete one or more associated inverters from your
list, it is necessary to run the guided procedure again, accessing it from the “Settings –
Configuration wizard" menu. On appearance of the table with the associated serial
numbers, simply click on the '-' key to deselect the inverter and delete it from the
associated list.
Any time a re-configuration is necessary, you must carry out the guided procedure.
NOTE: The guided configuration procedure is necessary, for example, when
an inverter is replaced or an inverter is added for monitoring.

6.7 BLUETOOTH® (OPTIONAL)
There is the possibility of having a Bluetooth® module as an optional interface for the
PVI-DESKTOP. This interface allows communication with PCs equipped with
Bluetooth® and dedicated software. It carries out all the functions implemented on the
USB port for data exchange and firmware upgrades.
Under normal operating conditions, the Bluetooth® function is disabled to eliminate
unnecessary power consumption. To enable this function you need to access the
appropriate menu.
NOTE: We recommend using Bluetooth® only when necessary and
disabling it immediately after use so as not to drain the battery quickly.
6.8 TOUCH SCREEN
Installation and Operator's Manual
(PVI-DESKTOP-yy-xx Rev: 1.1)
The PVI-DESKTOP is equipped with a resistive touch screen that allows easy and fast
navigation through the menus without pressing a keyboard, etc. At the back (see
Figure 2) there is a space where a stylus pen, for use to apply pressure on the screen,
can be inserted. The screen is sensitive to pressure from any object (fingers, pens, etc)
and only a light touch is needed to activate it. If necessary, there is a touch screen
calibration procedure that allows any errors in reading the pressure to be corrected.
WARNING: Take care to avoid touching the touch screen with sharp or
pointed objects or applying excessive pressure on the surface. Do not scratch,
strike violently or scrape the display surface and only use products specially
designed for cleaning LCD screens. Damage to the touch screen seriously
undermines the object's operating efficiency.
NOTE: We recommend using the stylus pen to prevent any staining or
soiling to the display surface.

7 SYSTEM OPERATION
Once the PVI-DESKTOP has been configured, it operates automatically and continues
to make data requests to the associated inverters, storing the replies. The device will
pass through different states during the process of normal operation. In particular, the
PVI-DESKTOP can be in three different conditions:
• FULL-ON MODE; in this mode the display is on and all functions are 100%
active. Every touch in an active area of the touch screen will make the page
change and execute the set commands.
• STAND-BY MODE; in this mode the PVI-DESKTOP display will be off, but
the object will be ready to react to a touch on the touch screen. The radio and
RS485 peripherals are 100% operational. A flashing blue LED will indicate
this state. The PVI-DESKTOP automatically goes into standby 1 minute after
the last touch screen command.
• SLEEP MODE; in this mode the whole system is on minimum consumption.
The peripherals are off and come back on automatically to send data requests
to the inverters. The user will not see any indication from the PVIDESKTOP. The device will go into this state only if it has been enabled
through the appropriate menu and after a time that can be set. To re-awaken
the system, press the ON/OFF key for at least one second.
• OFF MODE; by pressing the ON/OFF key for at least 5 seconds, a screen
will appear asking if you want to turn it off. By pressing 'OK', the object will
switch off completely and will not send any data requests by radio or RS485,
or perform any other operation, until it is switched back on. To switch the
PVI-DESKTOP back on, simply press the ON/OFF key.

8 FIRMWARE UPDATE
The PVI-DESKTOP can be upgraded very simply. The first step is to download the
latest available software directly from the website http:\\www.power-one.com\.
The downloaded file will be in the following form 'xxxyyy.ben'. To update the PVIDESKTOP, pull the SD card out (just a little pressure to pull it out) and insert it into
an SD card reader connected to your PC. Follow the instructions shown here:
1. Turn off the PVI-DESKTOP by pressing the ON/OFF key for more than 5
seconds and confirming on the display.
2. Take the SD card out of the PVI-DESKTOP by pressing lightly (ref. §6.4.).
3. Insert the SD card into a reader connected to the PC.
4. Check the formatting of the SD card by right-clicking on the appropriate
drive and selecting properties. Check that the formatting is FAT and not
FAT32.
5. Open the SD card drive where you will find several folders (language, theme,
etc.) including the folder 'BOOT'. If the folder 'BOOT' does not exist, create
it.
6. Copy the file downloaded from the Power-One website into the 'BOOT'
folder and, if necessary, rename it as "boot.ben".
7. Remove the SD card reader from the PC following the safe hardware removal
procedure, take the SD card out of the reader and put it back in the PVI-
DESKTOP.
8. Switch the PVI-DESKTOP back on.
9. Navigate the menu to select firmware update (ref. §5.2.).
10. On clicking next, the PVI-DESKTOP will start the update procedure.
11. Once the new software has been read and loaded, a selection dialogue will
appear on the screen. From this screen you can decide whether to install the
new firmware, return to the previous version or cancel the procedure and
keep the current firmware.
12. Wait until the PVI-DESKTOP finishes the installation operations to see the
menu automatically reappear.
It takes several minutes for the process to conclude and the display will show a screen
with the words "Boot...' during this time. This screen is completely normal and will
automatically disappear at the end of the process.
