Part 1 Introduction and Safety
1.4 SYSTEM INTEGRATION
1.4.1 THE MICRO INVERTER SYSTEM
This system is composed of a group of MICRO Inverters that convert direct electric current from a
photovoltaic module into alternating electric current and feeds it into the electric grid.
Photovoltaic modules transform energy from the sun into direct current (DC) electrical energy
(through a photovoltaic field, also called photovoltaic module). In order to use it, it is necessary to
transform the type of current into alternating “AC”. This conversion, known as DC to AC inversion,
is made efficiently without using rotating parts and only through static electronic devices.
In order to allow inverter operation in safe thermal and electrical conditions, in the event of
adverse environmental conditions or unsuitable input voltage values, the unit automatically
reduces the value of the power fed into the grid. This way the solar energy system compensates for
the energy drawn from the utilities connected to the grid to which it is linked. The solar energy
system therefore powers all connected electrical devices, from lighting to household appliances, etc.
When the photovoltaic system is not supplying sufficient power, the power needed to ensure
normal operation of the connected electrical devices is drawn from the national grid. If, on the other
hand, excess power is produced, this is fed directly into the grid, so becoming available to other
consumers.
In accordance with local and national regulations, the power produced can be sold to the grid or
credited towards future consumption, so bringing about a saving of money.
1.4.2 CHARACTERISTICS OF MICRO-INVERTERS
Unlike systems subdivided into strings controlled by one or several inverters, systems of this sort
are built for the incorporation of a MICRO Inverter for each photovoltaic module.
Each MICRO-Inverter works independently of the others, thus its own photovoltaic module supplies
the maximum power available to the grid. This setup enables a direct control over the production of
a single photovoltaic module, consequently optimizing production as much
as possible.
1.4.3 DESCRIPTION OF THE CDD
The Power-One devices (MICRO Inverters) associated with the CDD are monitored using CDD
display, the CDD web server interface, or from the Aurora Vision monitoring portal.
The display for the CDD permits simultaneous monitoring of all the devices associated to it.

Page 12 of 80 Instruction Manual for AURORA CDD BCG.00613_AA
Part 1 Introduction and Safety
The following information can be viewed by
navigating in the menu:
•Operating status of each MICRO Inverter
and statistics
•Operating status of the connection to the
Internet/local network
•Alarm messages and fault indicators
The display offers user friendly and intuitive use
with the option of navigating through the various
menus by means of buttons on the side of the
CDD.
1.4.4 OPERATING DIAGRAM
The diagram for this system shows how several wireless Power-One devices are connected to the
CDD device, which in turn interacts via WiFi or Ethernet with a PC or a router connected to the
Internet.
The system can be managed and monitored from a PC or Smartphone with Internet access if the
device is registered at the Power-One AURORA EASY VIEW web portal, described in Part 4.

2.1.2 INCOMING INSPECTION
It is the customer’s responsibility to examine the condition of the unit shipped. Upon receipt of
AURORA CDD, please perform the following check:
•Inspect the shipping container for any external damage.
•Inventory the contents against the listing below and verify receipt of all items. Use care not
to discard any equipment, parts, or manuals.
•Call the delivering carrier if damage or shortage is detected.
If inspection reveals damage to the inverter, contact the supplier, or authorized distributor for a

Part 3 Mounting and Configuration
3.1 WALL MOUNTING
The device uses radio waves to transmit and receive data, it is therefore important to assess this
factor in choosing the installation position.
Walls in reinforced cement and surfaces covered in metal (doors, shutters, etc.) can markedly re-
duce the reach of the device. It is advisable to undertake
all the configuration operations, before
fixing the CDD and installing it in the same location and position used during the configuration.
Also choose a place close to an electrical outlet and where the bottom part of the device, (where all
the connections are present, see Table 3-1), remains accessible.
The mounting instructions are as follows and referenced in the figure below:
1. Make the two holes necessary,
using a drill with a 5 mm
diameter bit. The depth of the
holes must be around 30 mm.
2. Insert plugs in the holes and
tighten the countersunk screws
supplied.
3. Fasten the CDD by putting the
head of the screws in the two
holes on the back.
4. In order to operate the system,
the CDD device must be
connected to a computer. The
type of connection can be:
•Cabled - The CDD is
equipped with an Ethernet
port
•Wireless - The CDD is
equipped with a WiFi
network card
During the commissioning of the
MICRO Inverter, verify that the
signal reception from the MICRO
Inverters and from the WiFi
router is sufficient.
