POSSIBLE REASONS WHY ACCESS VIA THE DATAMANAGER/HYBRIDMANAGER WEB INTERFACE VIA WLAN ACCESS POINT IS NOT POSSIBLE:
1.The end device (laptop, tablet, smartphone) is not connected to the WLAN access point:
On the inverter display, under “Setup” --> “Wi-Fi Access Point”, activate the Datamanager’s local WLAN network.
The inverter display shows the SSID name: “Fronius_xxx.xxxxx” and the network key “12345678” (always the same) after activation. On your end device, navigate to the WLAN settings and wait until the Fronius network “Fronius_xxx.xxxxx” appears in the list. Then click and connect to this network. The password (network key) is “12345678”. Important: The WLAN access point is a local WLAN connection (without Internet). On the end device, under WLAN Settings, disable “Automatic connection” and disconnect from the home network (WLAN network). The wireless end device driver always attempts to use the network that has the highest signal strength as a connection point.
2. Unable to connect to WLAN access point (WLAN access point not available)
Check the display under “Setup” --> “Datcom” --> “Protocol type” to see if “SOLAR NET” has been set. Then, under “Datcom” --> “Datcom Status”, check whether the status is “Error” or “Ok”.
If the status is “Ok” and the WLAN access point cannot be activated, contact your installer or Fronius technical support directly. If the status is “Error”, check the following: Remove the lower cover of the inverter and in the lower part check whether a terminating plug has been inserted in each “IN” and “OUT” port. If these two ports are free, insert the supplied terminating plugs (terminal plugs) or use a patch cable (LAN cable) and bridge the ports “IN” to “OUT”. Then check the display under “Setup” --> “Datcom Status” to see if the status has changed from “Error” to “OK”.
Then check if the WLAN access point is now available.
3. An incorrect IP address used for access:
Open your browser (preferably Google Chrome) and enter the IP address “192.168.250.181” into the address bar (URL field) right at the top. Confirm with the Enter key. If this does not resolve the issue, try another browser (Edge, Mozilla Firefox or Opera) to access the web interface.
If the attempt fails again, try physically accessing the web interface via LAN.
ACCESSING THE WEB INTERFACE VIA LAN:
Unscrew the lower cover of the inverter to gain access to the LAN port of the Datamanager card. Using a LAN cable, connect your computer (laptop/PC) to the Datamanager LAN input (LAN input to the right of the WLAN antenna) and set the DIP switch next to the four LEDs arranged in a square to position “A” (left position).
Now open any browser (preferably Google Chrome) and enter the IP address “169.254.0.180” in the address bar. Confirm with the Enter key. If you are also physically unable to access the web interface via LAN, continue with the second point.
CANNOT PHYSICALLY ACCESS THE DATAMANAGER/HYBRIDMANAGER WEB INTERFACE VIA LAN
1. The end device (laptop, PC) is not physically connected to the Datamanager/Hybridmanager via LAN:
Check that you have established a physical LAN connection (RJ45 cable) between the end device (laptop, PC) and the Datamanager/Hybridmanager (remove lower cover of the inverter and insert one end of the LAN cable in the LAN port to the right of the WLAN antenna). If necessary, replace the LAN cable (RJ45 cable) and try accessing the web interface again.
2. The DIP switch is set to position “B”:
Remove the lower cover of the inverter and check that the small DIP switch next to the four LEDs arranged in a square is positioned to the left. If it is shifted to the right (position “B”), move it to the left to position “A”.
3. None of the above points apply and it is still not possible to connect to the web interface:
Please contact your installer.
