Activate Wps Function; Switching Wlan On And Off - SMA SUNNY ISLAND 4.4M Operating Manual

9 Configuration of the Inverter
1. Activate the user interface of the inverter (see Section 8.1, page 110).
2. Log in as Installer (see Section 8.2, page 112).
3. Select Device > Operation > Time control.
4. Set time-controlled inverter operation:
• Set the parameter Start date for time-controlled inverter operation to the desired start date.
• Set the parameter Start date for time-controlled inverter operation to the desired start time.
• Set the parameter Operating time for time-controlled inverter op. to the desired operating time.
• Select the Repetition cycle for time-controlled inverter operation / Repetition parameter and set it to
the desired repetition cycle.
5. To activate time-controlled inverter operation, select the parameter Time-controlled inverter operation and set
it Yes.
☑ Time-controlled inverter operation is active. If the Sunny Island has started automatically under time-control and
you stop the Sunny Island, time-controlled inverter operation is deactivated automatically.

Activate WPS Function

• Activate the WPS function on the inverter. To do this, tap on the enclosure lid of the inverter twice.
☑ A signal sounds for one second followed by a one second break. After this break the signal sounds again for
one second.
The inverter deactivates the WPS function automatically. When this happens, a signal sounds: long signal (one second)
> break (one second) > very long signal (three seconds).

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 9.2 "Changing
Operating Parameters", page 119).
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.
