performed by the installer or by qualified personnel.
8.11.1 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
Identification 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
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.
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.
