The basic procedure for changing operating parameters is explained in another section (see
Section8.10 "Changing Operating Parameters", page55).
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.
Procedure:
• To switch off the direct connection in the parameter group PV system communication >
WLAN, select the parameter Soft-access-point is turned on and set this to No.
• To switch off the connection in the local network in the parameter group PV system
communication > WLAN, select the parameter WLAN is turned on and set this to No.
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
to Yes.
• To switch on the WLAN connection in the local network, in the parameter group System
communication > WLAN, select the parameter WLAN is turned on and set this to Yes.
8.8 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 lit permanently to signalize feed-in operation.
The basic procedure for changing operating parameters is explained in another section (see
Section8.10 "Changing Operating Parameters", page55).
Procedure:
• In the parameter group Device > Operation, select the parameter Dynamic power
display via green LED and set this to Off.
