Wireless Connection (Wi-Fi)

The wireless connection of the CDD to PC must be done using a Wi-Fi router 

which operates as a “bridge” for the transmission of data.

Before starting the configuration process, make sure you have a Wi-Fi router 

with standard IEEE 802.11b/g, and visible SSID. In addition to unprotected 

networks, WPA and WPA-2 protected protocols are supported.

• 

Turn on the CDD

• 

The CDD will automatically detect the local Wi-Fi 

networks within reach of the device

• 

On the display the number of networks detected (XX) is displayed

• 

Press (ENTER) to access to the menu for the selelction of  Wi-Fi network

• 

The first line displays the number of networks (XX), type of protection (Open, 

WPA/WPA2) and signal level (indicated with“



”). The 

second line displays the name of the network (SSID). 

The level of the signal may vary from one to four. 

The next step of the installation depends of the type of network selected (Open, 

WPA/WPA2) and the presence or absence of MAC addresses filters.

1. Configuration with open networks (Open)

A. Open networks without MAC addresses filters

• If the signal is sufficent, the CDD starts the connection to the Wi-Fi 

network within a few seconds.

• A confirmation message will be displayed 

• At the end of the procedure the message   ”Wi-Fi Enabled” will appear.

B. Open networks with MAC addresses filters 

• If the router has a filter for MAC addresses the connection fails and an 

error message will be displayed.

• Afterwards the MAC address of the CDD will 

be displayed. Write down the address and  add 

it among the enabled MAC addresses on the configuration menu of the 

router. 

• Once the router is configured, switch off the CDD and restart this 

procedure.

2. Configuration with protected WPA/WPA2 networks

A. Protected networks without MAC addresses filters

• Before starting the connection attempt, the CDD requires an access key 

of the Wi-Fi network.

By using the UP and DOWN keys to screen through the list of 

characters, and choosing ENTER to confirm the selected character.

• Press ENTER two times to start the connection attempt.

• At the end of the procedure the message “Wi-Fi Enabled” will appear.

B. Protected networks with MAC addresses filters 

• If the router has a filter for MAC addresses will be necessary to configure 

it with the same procedure previously explained for protected networks 

without MAC address filters. 

• At the end of the procedure the connection 

fails and on the display shows an error message.

• Afterwards the MAC address of the CDD will be 

displayed. Write down the address and add it among the enabled MAC 

addresses on the configuration menu of the router.

• Once the router is configured, switch off the CDD and restart this 

procedure.

Autoconnection Configuration 

The CDD automatically stores the parameters of the last connection (SSID 

and access key). So, if autoconnection is enabled, the CDD will automatically 

connect to the Wi-Fi. 

To enable/disable the autoconnection function:

• 

Press ESC to access the previous level of the menu

• 

Press UP or DOWN up to “Autoconnection” and then ENTER

• 

Press UP or DOWN to enable/disable the function. 

• 

Press ENTER to confirm the selection and ESC to go back to GENERAL 

INFORMATION.

Staff authorised to carry out the installation must be specialised and experienced in this job; they must also have received suitable training on equipment of this 

type

.

For Safety reasons only a qualified electrician, who has received training and / or has demostrated skills and knowledge in construction and in 

operation of this unit, can install this inverter.
The installation must be done by qualified installers and/or licensed electrician 

according to the applicable local code regulations 
The connection of an inverter energy system to an electrical installation connected to 

the electricity distribution network must be approved by the appropriate electrical 

distributor.

The installation must be carried out with the equipment disconnected from the grid .

Walls of 

reinforced cement

 and surfaces covered in 

metal

 (doors, shutters, etc.) can 

markedly 

reduce

 the reach of the device. 

It is therefore advisable to undertake all the configuration 

operations, before hooking the CDD and installing it in the same location and position 

used during the configuration.

Also choose a place close to a socket (necessary for power) and where the lower part of CDD, 

where all the connections are present, remains accessible. 

• 

Make 2 holes necessary to hang the CDD to the wall, using a drill with a 5 mm diameter bit. The 

depth of the holes must be around 30 mm.

• 

Insert anchors in the holes and tighten the countersunk screws.

• 

Hang the CDD by inserting the head of the 2 screws into the holes on the back of CDD.

• 

Insert the special power connector on the underside of the CDD and power the device by 

connecting the AC adapter  (supplied) to an electrical outlet.  The power supply comes with 

4 interchangeables plugs compatible with the sockets of different countries

• 

In order to operate the plant, the CDD device must be connected to a 

PC. 

 

The type of connection can be:

 

Cabled - The device is equipped with an 

Ethernet

 port 

 

Wireless -The device is equipped with a 

Wi-Fi

 network card

During the commissioning of the plant verify that the signal reception from the MICRO inverters and from the Wi-Fi 

router is sufficient.

The plant is composed by a group of MICRO inverters that convert direct electric current from a photovoltaic module into alternating electric current and feeds it 

to the electrical grid. 

Photovoltaic panels transform energy from the sun into direct current (DC) electrical energy; however, to feed the grid and so that this energy can be used, it has 

to be transformed into alternating current (AC). This conversion, known as DC to AC inversion, is made efficiently without using rotating parts and only through 

static electronic devices.

The AURORA MICRO automatically reduces the value of the power fed into the grid in the event of adverse environmental conditions or unsuitable input voltage 

values.

When used in parallel with the grid, the alternating current generated by the inverter flows directly into the domestic electrical circuit, which is in turn connected, 

through a load distribution panel, to the grid. 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 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 electric utility regulations, the power produced can be sold to the grid or credited towards future consumption, bringing about a saving 

of energy.

Characteristics of a system employing AURORA MICRO inverters

AURORA MICRO inverters fit one per PV panel, so each individual PV panel’s output is optimized independently of the others.  This differs from a system with a 

single, larger, inverter for a group of panels;  in this case a single shaded or otherwise impaired panel lowers the output of the entire group. 

The equipment  includes safety devices suitable for the protection of components and operators.
