Operations on the inverter to identify and address any faults may only be performed by the
installer or by qualified personnel.

nternal Webserver and wireless communication troubleshooting
The following table gives a list of main and common errors or problems relating to the wireless
communication between inverter and user devices.
Problem
The internal webserver cannot be
accessed.
The inverter is able to identify a
wireless network but is unable to
connect to it.
The Inverter has not identified the
wireless network to which connection
is required.
The wireless board does not
communicate correctly with the
inverter inside of which it is installed
(inconsistency
in
the
detected
data read by the board), or when
working in "Access Point Mode", it's
not possible to access the internal
webserver.
Alternating difficulties in the local
connection to the internal webserver.
Possible causes
ADMIN or USER password forgotten.
The signal between the inverter and the
wireless router to which the board wants
to connect is too weak.
The wireless network to which the
inverter is to be connected, could
require the user to enter a username
and password to allow navigation (for
example, with a public wireless network
or a hotel).
The wireless network to which the
Inverter is to be connected, is set so as
not to be identified (hidden network).
The signal between the inverter and the
wireless router to which the board wants
to connect is too weak.
The wireless board of the inverter could
be damaged.
Wrong Inverter Date/Time settings.
The inverter might not be correctly
powered (for example, if the inverter
is switched off at night, the internal
webserver cannot be accessed).
The wireless connection signal between
the device in use and the router or the
Inverter, may not have sufficient power
or it may be disturbed by obstacles
which affect the communication.

Solution
Reset the passwords by clicking on "Forgot your password"; The
passwords can be reset after having entered the "Product Key"
code that can be found on the "Wireless Identification Label".
Modify the position of the wireless antenna, the inverter or the
router.
Make sure that the inverter has not been installed near obstacles
which could affect the communication with the wireless router
(for example: metal cages or walls, walls in reinforced concrete,
electromagnetic fields).
Move the router as close as possible to the inverter.
Install a wireless signal repeater in order to extend the network
to which the inverter is to be connected; then connect the
inverter to the repeater.
Unfortunately the inverter cannot be connected to these types
of wireless networks. Connect the inverter to an alternative
wireless network.
The Inverter is not able to connect to a hidden network. Set the
wireless network to which the inverter is to be connected (visible
network), then identify and connect the Inverter to the wireless
network as normal.
Modify the position of the wireless antenna, the inverter or the
router.
Make sure that the inverter has not been installed near obstacles
which could affect the communication with the wireless router
(for example: metal cages or walls, walls in reinforced concrete,
electromagnetic fields).
Move the router as close as possible to the inverter.
Install a wireless signal repeater in order to extend the network
to which the inverter is to be connected; then connect the
inverter to the repeater.
Request a service intervention to check that the inverter wireless
board is working correctly.
Check if Date/Time has correctly set on the inverter; correct it
if necessary.
Access to the internal webserver only when the inverter is
correctly powered.
Make sure that the signal between the wireless devices which
interact with the inverter are sufficiently high and that any
obstacles such as metal cages or walls, walls in reinforced
concrete or strong electromagnetic fields do not affect
communication.
