Troubleshooting
Operations on the inverter to identify and address any faults may only be performed by the
installer or by qualied personnel.
Web User Interface and wireless communication troubleshooting
The following table gives a list of main and most common errors or problems relating to the
wireless communication between inverter and user devices.
Problem Possible causes Solution
The Web User Interface cannot be
accessed.
ADMIN or USER password forgotten.
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 “Communication Identication
Label”.
The inverter is able to identify a
wireless network but is unable to
connect to it.
The signal between the inverter and the
wireless router to which the board wants
to connect is too weak.
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 elds).
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.
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).
Unfortunately the inverter cannot be connected to these types
of wireless networks. Connect the inverter to an alternative
wireless network.
The Inverter has not identied the
wireless network to which connection
is required.
The wireless network to which the
Inverter is to be connected, is set so as
not to be identied (hidden 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.
The signal between the inverter and the
wireless router to which the board wants
to connect is too weak.
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 elds).
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.
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 Web User
Interface.
The wireless board of the inverter could
be damaged.
Request a service intervention to check that the inverter wireless
board is working correctly.
Wrong Inverter Date/Time settings.
Check if Date/Time has correctly set on the inverter; correct it
if necessary.
