Fronius Solar.web Support

General info & notes on Fronius Solar.web.

A system is displayed as “offline” if the internet connection to the device is faulty or interrupted. The following reasons may explain why your system is not transmitting any data to the portal:
  • The Fronius Datamanager (integrated network card in the inverter or externally as a box) has not been put into operation.
    Contact your installer about this and ask whether the Datamanager has been put into operation and brought online.
  • Your router or modem has lost its internet connection
    Use your smartphone or laptop to connect to your router/modem via LAN or WLAN and check whether you can access a website, e.g. www.fronius.com. If the connection to the inverter has been established via LAN cable, we recommend checking the LAN cable:

    1. Disconnect the LAN cable from the Datamanager (inverter) and plug it into the LAN input of the laptop.
    2. Disconnect yourself from all WLAN networks or, even better, switch off the WLAN interface on the laptop completely.
    3. Try to access a website e.g. www.fronius.com via this LAN connection. If you can successfully access this website, please proceed as follows:

    Switch off the power (AC and DC) to the inverter and then disconnect the router from the power supply as well. Wait a few seconds (about 30 seconds) and then switch on the router, wait about 2 minutes and then switch on the inverter again on both the AC and DC sides.
  • The internet router/modem has been changed
    The Datamanager must be connected to your new network. Click here for instructions on how to reconfigure the network.
    - The WLAN password or the network name of the home network has been changed
    - The Datamanager must be connected to your new network
  1. Check component visibility
    In Solar.web, navigate to “Components” under “Settings” and check the visibility of Smart Meters and inverters. At first glance, the hidden components are not visible.

  4. Update Datamanager software version
    To update the Datamanager to the current version, you can navigate to “Components” under “Settings” on Solar.web and initiate an update to a current software version for the data source ID (Datamanager) (if a current firmware version is available for you).

  5. LocalNet (Fronius Solar Net) connection faulty
    There is faulty communication from the component to the Datamanager Under “Setup” --> “Datcom” --> “Datcom Status”, check whether the status is “OK” or “Error”. If the Datcom status is set to “OK”, you have gone through all of the above points and still no archive data appears in the energy balance, the Datamanager may be affected by a fault. Please contact your installer. If the Datcom status is “Error”, check the following steps:

    / Check the display under “Setup” --> “Datcom” --> “Protocol type” to see if “SOLAR NET” has been set.
    / Remove the lower cover from the inverter and check below the inverter whether a terminating plug has been inserted in each “IN” and “OUT” port --> in the “IN” and “OUT” connection sockets. 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 whether the Datcom status has changed from “Error” to “OK”.

    Important:
    If the Datcom status changes from “Error” to “OK”, you may have to wait until the archive data is sent to Solar.web. (see --> anchor link to “Recently started for the first time”). If the Datcom status is still “Error”, please contact your installer. 

  6. None of the above applies
    If the Datamanager has an up-to-date firmware version and all settings have been made as described above, then you can reset the Datamanager to factory settings using the reset link. However, you must be connected to the Datamanager via LAN or WLAN access point in advance in order to be able to use this command line.

    Command line: Use via WLAN access point:
    192.168.250.181/admincgi-bin/configRevert.cgi?scope=all

    Set up connection to the Datamanager via WLAN access point:
    On the inverter display, use the control panel to navigate to “Setup” and activate the WLAN access point. Then connect to this WLAN access point “Fronius_240.xxxx” with a laptop/tablet/smartphone using the network key “12345678”.

    Command line: Use via LAN:
    169.254.0.180/admincgi-bin/configRevert.cgi?scope=all

    Set up connection to the Datamanager via LAN:
    Remove the lower cover of the inverter to access the Datamanager card LAN port. Connect a LAN cable from 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).


  1. Select the setup menu on the inverter display.
  2. Start the WLAN hot spot.
  3. The SS number displayed is your Datamanager ID.You will need your Datamanager number to complete the “Data sources” field.

 
If you want to create a new system in Fronius Solar.web or add another data source to an existing system, the message “Datalogger ID already in use” may appear:
  • The Datalogger ID is incorrect
    Please check the ID you entered for accuracy.  For example, the Datalogger ID can be found on the inverter display under Setup --> Wi-Fi Access Point. To do this, activate the access point. The Fronius Datalogger ID is then displayed in 240.XXXX or 239.XXXX format as part of the SSID.
  • The Datalogger ID is already in use for an existing Fronius Solar.web system
    Check whether you have added the Datalogger ID through another Fronius Solar.web account or whether the ID is already assigned to another of your systems. If this is not the case, please check with your system installer to see if they have already added the system for you in Fronius Solar.web.

 

  Possible reasons for a failed update attempt:
  • The Internet connection to the Fronius Datamanager is not stable
    Verify that a stable connection to the Datamanager has been established. If necessary, run a speed test for your Internet connection: https://www.speedtest.net
  • Connection to the inverter (Datamanager) set up via WLAN:
    Check the signal strength of your WLAN connection (at least 2 of 4 black bars) under “Networks found”. Proceed as follows:

    Access the web interface via WLAN Access Point:
    Use the control panel to navigate to “Setup” on the inverter display and activate the WLAN access point. Then connect to this WLAN Access Point “Fronius_240.xxxx” with a laptop/tablet/smartphone using the password “12345678”. Now open any browser (preferably Google Chrome) and enter the IP address “192.168.250.181” in the address bar. Confirm with the Enter key. On the web interface, navigate to “Settings” --> “Network”. Alternatively, try to position the router closer to the inverter or use a wireless amplifier between the router and the inverter for a more stable wireless connection. Otherwise, connect to the inverter (Datamanager) via LAN. This ensures a more stable connection.
  • The inverter has failed during the update process
    Check that the inverter display lights up. If the display does not light up, tap a button on the control panel at the bottom of the inverter and check whether the display lights up. If the display does not light up, check whether the residual current circuit breaker or the circuit breaker in the control cabinet has failed. In most cases, the switches are labelled in the switch cabinet. If you cannot find the residual current circuit breaker or the circuit breaker in the switch cabinet, please contact your installer.

 



In order for Fronius Solar.web to display your direct current consumption, a Fronius Smart Meter must be installed. The following link will provide you with detailed information about this device:

Fronius Smart Meter  

 

Possible reasons for missing components in Fronius Solar.web:

  • Initial commissioning was recently carried out
    The components appear as soon as the first archive data packet is sent to Fronius Solar.web. Archive data transmission activated hourly: The Fronius Datamanager sends archive data packets to Fronius Solar.web every hour. The hours when archive data is to be sent are selected on the Datamanager web interface. Archive data transmission activated daily: The Datamanager sends the archive data packets to Fronius Solar.web at a set time every day. This means that after initial commissioning, the components may not be displayed until later.
  • Check the status for component visibility
    In Solar.web, navigate to “Components” under “Settings” and check the visibility of Smart Meters (energy meters) and inverters. At first glance, the hidden components are not visible. To display the hidden components, click on “Show all” to the right of “Energy meters” or “Inverters”. The hidden components are then displayed in the list. Under “Visible”, click the crossed-out eye icon to reveal the component.
  • Incorrect communication from the component to the Datamanager
    Under “Setup” --> “Datcom” --> “Datcom Status”, check whether the status is “OK” or “Error”. If The Datcom status is set to “OK”, you have gone through all of the above points and still no archive data appears in the energy balance, the Datamanager may be affected by a fault. Please contact your installer. If the Datcom status is “Error”, check the following steps:

    1. Check the display under “Setup” --> “Datcom” --> “Protocol type” to see if “SOLAR NET” has been set.
    2. Remove the lower cover from the inverter and below the inverter 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 that the Datcom status has changed from “Error” to “OK”. Important: If the Datcom status changes from “Error” to “OK”, you may have to wait until the archive data is sent to Fronius Solar.web. If the Datcom status is still “Error”, please contact your installer.

Possible reasons for incorrect or missing calculation of earning:
  • No tariff settings have been made on Fronius Solar.web.
    The value shown for the earning consists of the yield and the savings of your PV system for the specified period.

    Yield = energy fed into the grid multiplied by your tariff
    Saving = directly consumed energy multiplied by your tariff

    In order to use the function, tariffs must be stored in the settings beforehand. You can enter the tariffs directly on Solar.web under “Settings” --> “Tariffs”. After the tariff settings have been applied, Solar.web will carry out the calculations automatically. Note that the calculation of yield data may take some time after a tariff is applied or changed.
  • The Fronius Smart Meter has failed (only production can be seen)
    A failure of the Fronius Smart Meter will result in some profitability data not being used in the calculation for the set tariff “with Fronius Smart Meter”. Check on Solar.web under “Settings” --> “Components” to see if the Smart Meter appears under “Energy meters”.
    >If you do not see a Fronius Smart Meter, or if other Fronius Smart Meters are missing under “Components”, check whether it says “Show all” in blue to the right of the “Energy meters” text. If so, click on this text. The hidden components should now be displayed in the list. Then click the crossed-out eye icon under “Active” to re-display the components.
Possible reasons for constant consumption during the night hours or lack of consumption data:
  • Logging during the night hours has been deactivated:
    The “Logging during the night hours” setting is activated in the Datamanager’s web interface. To enable the feature:

    Access the web interface via WLAN access point:
    Use the control panel to navigate to “Setup” on the inverter display and activate the WLAN access point. Then connect to this WLAN access point “Fronius_240.xxxx” with a laptop/tablet/smartphone using the password “12345678”. Now open any browser (preferably Google Chrome) and enter the IP address “192.168.250.181” in the address bar. Confirm with the Enter key. On the web interface, navigate to “Fronius Solar.web” under “Settings”. In this menu, activate the “Logging during the night hours” function.

    Access to the web interface via LAN:
    Remove the lower cover from the inverter to access the Datamanager card LAN port. Connect a LAN cable from 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. On the web interface, navigate to “Fronius Solar.web” under “Settings”. In this menu, activate the “Logging during the night hours” function.
  • The inverter is in “night mode”
    If you want to log data about your consumption, etc. during the night hours, you can select this on the inverter display under “Setup” --> “Display settings” --> “Night mode”.

    “Off” means that the entire system is switched off.
    “Auto” means that the display is off, but data is logged.
    “On” means that the display is on and data is logged.

    Whether data is transferred to Fronius Solar.web at night depends on the settings you have made in the Datamanager’s web interface. You can check these in the web interface under the “Fronius Solar.web” tab -> “Send data to Solar.web”.
