8.10 Troubleshooting
ATTENTION –
A
Operations on the inverter to identify and address any faults may only be performed by the installer or by qualified
personnel.
8.10.1 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.
The Inverter has not identified
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 identified (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 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 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.
Alternating difficulties in the local
connection to the Web User
Interface.
The inverter might not be correctly
powered (for example, if the
inverter is switched off at night,
the Web User Interface cannot be
accessed).
Access to the Web User Interface only when the inverter is
correctly powered.
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.
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.
