  3. Standard IP address for a direct connection via WLAN outside of a local network: 192.168.12.3

Importing and exporting files with end devices having an iOS operating system is not possible.

For technical reasons, importing and exporting files (e.g. importing an inverter configuration, saving the current inverter configuration or exporting events and parameters) is not possible with mobile end devices having an iOS operating system.

  1. Use an end device that does not have an iOS operating system for importing and exporting files.

You have several options to connect the product to an end device. The procedure can be different depending on the end devices. If the procedures described do not apply to your end device, establish the direct connection via WLAN as described in the manual of your end device.

The following connection options ar available:

  • Connection with Captive Portal

  • Connection with WPS

  • Connection with WLAN network search

Requirement:

  • An end device with QR Code scanner must be available.

Procedure:

  1. Scan the QR Code attached to the product with an end device.
  2. The end device automatically connects to the inverter. The web browser of your end device opens and the login page of the user interface is displayed.
  3. If the web browser of your end device does not open automatically and the login page of the user interface is not displayed, open the web browser and enter http://smalogin.net in the address bar.

Connection with WPS

Requirement:

  • The end device must have a WPS function.

Procedure:

Connection with WLAN network search

  1. Search for WLAN networks with your end device.
  2. Select the SSID of the inverter SMA[serial number] in the list with the found WLAN networks.
  3. Enter the inverter WLAN password.
  4. Open the web browser of your end device and enter http://smalogin.net in the address bar.
  5. The login page of the user interface is displayed.
  6. If the login page of the user interface does not open, enter the IP address 192.168.12.3 or, if your end device supports mDNS services, SMA[serial number].local or http://SMA[serial number] in the address bar of the web browser and press the enter key.
