Switching WLAN On and Off
(ch) 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.
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.
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.
All work on the inverter and the cabling of the PV array must be carried out by an electrically qualified person.
