6.10 Switching WLAN On and Off

The inverter is equipped with an activated WLAN interface as standard. If you do not want to use
WLAN, you can switch the WLAN function off and switch it on again whenever needed. In doing
so, you can switch the WLAN direct connection and the WLAN connection in the local network on
independently of each other.
Switching on the WLAN function only possible via Ethernet connection
If you switch off both the WLAN function for the direct connection and for the connection in
the local network, access to the inverter user interface and therefore reactivation of the WLAN
interface is only possible via an Ethernet connection.
The basic procedure for changing operating parameters is explained in another section (see
Section 6.1 "Changing Operating Parameters", page 30).
Switching WLAN Off
If you would like to switch the WLAN function off completely, you must switch off both the direct
connection and the connection in the local network.

Switching WLAN On
If you have switched the WLAN function for direct connection or for connection in the local network
off, you can switch the WLAN function back on in accordance with the following procedure.
Requirement:
☐ If the WLAN function was previously switched off completely, the inverter must be connected
to a computer or router via Ethernet.
Procedure:
• To switch on the WLAN direct connection, in the parameter group PV system
communication > WLAN, select the parameter Soft-access-point is turned on and set this
