9.16 Switching the Dynamic Power Display Off
As standard, the inverter signals its power dynamically via the pulsing of the green LED. When
doing so, the LED flashes on and off uniformly or is permanently lit at full power. The various
gradations are related here to the set active power limit of the inverter. If this display is not desired,
switch this function off in accordance with the following procedure. Once this has been done, the
green LED is only lit permanently to signalize feed-in operation.
The basic procedure for changing operating parameters is explained in another section (see
Section 9.14 "Changing Operating Parameters", page 46).
Procedure:
• In the parameter group Device > Operation, select the parameter Dynamic power
display via green LED and set this to Off.
9.17 Switching WLAN 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 in accordance with the following procedure. In
doing so, you can switch the WLAN direct connection and the WLAN connection in the local
network on or off independently of each other. If you would like to switch the WLAN function off
completely, you must switch off both the WLAN direct connection and the WLAN connection in the
local network.
The basic procedure for changing operating parameters is explained in another section (see
Section 9.14 "Changing Operating Parameters", page 46).
Switching on the WLAN function only possible via Ethernet connection
If you switch off both the WLAN function for the WLAN direct connection and for the WLAN
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.
Procedure:
• To switch off the WLAN direct connection, select the parameter Soft-access-point is turned
on and set this to No.
• To switch off the WLAN connection in the local network, select the parameter WLAN is
turned on and set this to No.
9.18 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. In
doing so, you can switch the WLAN direct connection and the WLAN connection in the local
network on independently of each other.
The basic procedure for changing operating parameters is explained in another section (see
Section 9.14 "Changing Operating Parameters", page 46).
Requirement:
☐ If the WLAN function was previously switched off completely, the inverter must be connected
to a computer or router via Ethernet.
