1. Internal Wi-Fi card
1.1. Installation
The installation of an internal Wi-Fi card is only required for single-phase photovoltaic inverters
from the Azzurro 1PH 1100TL - 3000TL-V1 and 1PH 3000TLM - 6000TLM-V1 range not equipped
with on-board Wi-Fi card.
The 3000SP V1 storage inverter always comes with an internal Wi-Fi card.
In order to monitor the inverter, the RS485 communication address must be set to 01 directly from
the display.
Installation tools:
5-mm Allen key
Internal Wi-Fi card
To view the “Warranty Terms and Conditions” offered by ZCS Azzurro, please refer to the
documentation inside the product box and on the website www.zcsazzurro.com.
1) Switch off the photovoltaic inverter by first disconnecting the AC line via the appropriate
wall switch and then the DC line via the appropriate wall switch.
2) Unscrew and remove the four Allen screws on the front panel of the inverter using a 5 mm
screwdriver.

7) Reconnect the flat cable in its slot and close the two plastic hooks, making sure that they are
closed properly. Place the front cover in its original position and secure by rescrewing the
four Allen screws that were previously removed.
8) Start the inverter in the regular way as described in the manual, first supplying DC voltage
and then AC voltage using the wall-mounted switches.
1.2. Configuration
Configuration of the Wi-Fi card requires the presence of a Wi-Fi network near the inverter in order
to achieve stable transmission of data from the inverter card to the Wi-Fi modem.
Tools required for configuration:
Smartphone, PC or tablet
Go to front of the inverter and search for the Wi-Fi network using a smartphone, PC or tablet,
making sure that the signal from the home Wi-Fi network reaches the place where the inverter is
installed.
If the Wi-Fi signal is present at the location where the inverter is installed, the configuration
procedure can begin.
If the Wi-Fi signal does not reach the inverter, a system must be installed to amplify the signal and
bring it to the installation location.

1.4. Troubleshooting
1. The AP_******** Wi-Fi network generated by the card installed on the inverter is not
visible
-Check the Modbus address set on the inverter:
Enter the main menu with the ESC key (first key on the left), go to System Info and press
ENTER to enter the submenu. Scroll down to the Modbus address parameter and make
sure it is set to 01 (and in any case, other than 00).
If the value set is different from 01, go to Settings and enter the Modbus Address menu
where the 01 value can be set.

15 / 45
-Check that the card is correctly connected to the mechanics of the inverter.
If necessary, disconnect the card from its slot and insert again.
-Check that the Wi-Fi symbol is present in the top right-hand corner of the inverter's
display (steady or flashing).
Figure 18 –Icon on the display of inverters
2. The Signal Quality is 0% and the IP Address is 0.0.0.0
-Check that the configuration procedure has been carried out correctly and that the
correct network password has been entered.
-Reset the card as described in the previous section and configure again.
3. The Remote Server A item is Unpingable
-When searching for the Wi-Fi network using a smartphone or PC, make sure that the Wi-
Fi signal is strong enough (a minimum RSSI signal strength of 30% is required during
configuration). Check that you have correctly extracted the Wi-Fi antenna and, if
necessary, increase the signal strength by using a network extender or a router
dedicated to monitoring the inverter.
-Check that the router has access to the network and that the connection is stable; check
that it is possible to access the Internet from a PC or smartphone.
-Check that port 80 of the router is open and enabled to send data
-Reset the card as described in the previous section and configure again.
-If, at the end of the previous checks and subsequent configuration, Remote server A is
still configured to “Unpingable”, then there may be a transmission problem at the home
network level and, specifically, that data between the router and server is not being
transmitted correctly. In this case, it is advisable to carry out checks at the router level in
order to ensure that there are no obstructions on the output of data packets to our
server.
-To make sure that the problem lies in the home router and to exclude problems with the
Wi-Fi card, configure the card using the Wi-Fi hotspot function on your smartphone as a
reference wireless network.

Using an Android mobile phone as a modem
a) Check that the 3G/LTE connection is active on your smartphone. Go to the Settings menu
of the operating system (the gear icon on the screen with a list of all the apps installed on
the phone), select “Other” from the Wireless and networks menu and make sure that the
Network type is set to 3G/4G/5G.
b) In the Android settings menu, go to Wireless & networks > Other. Select Mobile
Hotspot/Tethering, and then enable the Wi-Fi mobile hotspot option; wait a few seconds
for the wireless network to be created. To change the name of the wireless network
(SSID) or your password, select Configure Wi-Fi hotspot.

•Using an iPhone as a modem
a) In order to share the iPhone connection, verify that the 3G/LTE network is active by
going to Settings > Mobile Phone, and making sure that the “Voice and data” option is set
to 5G, 4G or 3G. To enter the iOS settings menu, click the grey gear icon on the home
screen of your phone.
b) Go to the Settings menu > Personal Hotspot and turn on the Personal Hotspot option.
The hotspot is now enabled. To change the password of the Wi-Fi network, select Wi-Fi
password from the personal hotspot menu.

17 / 45
Figure 20 - Configuration of an iOS smartphone as a hotspot router
At this point, it is necessary to re-configure the Wi-Fi card using a PC or smartphone other
than the one used as a modem.
During this procedure, when asked to select the Wi-Fi network, choose the one activated by
the smartphone and then enter the password associated with it (which can be changed from
the personal hotspot settings). If at the end of the configuration the word “Unpingable”
appears next to “Remote Server A”, then the problem depends on the home router.
It is therefore advisable to check the brand and model of the home router you are trying to
connect to the Wi-Fi card; some router brands may have closed communication ports. In this
case, contact the customer service of the router’s manufacturer and ask them to open port
80 (direct from the network to external users).

2. External Wi-Fi adapter
2.1. Installation
Unlike the internal Wi-Fi card, the external adapter must be installed for all compatible inverters.
However, the procedure is quicker and easier as there is no need to open the front cover of the
inverter.
In order to monitor the inverter, the RS485 communication address must be set to 01 directly from
the display.
Installation tools:
Cross screwdriver
External Wi-Fi adapter
1) Switch off the inverter following the procedure described in this manual.
2) Remove the cover for accessing the Wi-Fi connector on the bottom of the inverter by
unscrewing the two cross-head screws (a), or by unscrewing the cover (b), as shown in the
