Please be aware that all generation and consumption data from your system will be permanently deleted. If you have purchased a Fronius Warranty or Fronius Solar.web Premium, we are legally required to continue to store your personal details.
  • Have you already added your PV system to Fronius Solar.web? If not, please download the Fronius Solar.start app from the relevant app store. You will then be guided through the process step by step. Alternatively, go to Fronius Solar.web and select "Add your PV system" on the main screen. As soon as your PV system has been added and is sending data to Fronius Solar.web, the device will also be displayed and you will then be able to register it.
  • If you have already added your PV system, it is possible that you have been assigned guest rights for monitoring your system. The inverters associated with a PV system are only displayed if you have supervisor or owner rights.
Yes. You can change your details at any time in Fronius Solar.web – simply go to the "User settings" section of your user account. Please note that by agreeing to the general terms and conditions of Fronius Solar.web, you confirmed that your details were correct. Providing incorrect information represents a breach of the general terms and conditions. For this reason, we ask that you always check your information carefully and ensure it is up-to-date. 
The general terms and conditions for Fronius Solar.web can be found here.
Your user account and completed orders contain confidential data. For security reasons, and to prevent unauthorised persons gaining access to this data, we only communicate with our users using the e-mail address verified during the registration process. This ensures that we only communicate with the owner of the user account. If you no longer have access to this e-mail address, please send us a copy of your valid ID. This allows us to check that you have the right to access this data.
The data sources for your PV system can be found on the display of your inverter. If you launch the wireless hotspot from the menu, a number, beginning with 239 or 240 is displayed: this is your Datalogger ID (datamanager). Please mention that you'll need your V.Code, if you have a Gen24/Tauro inverter installed. You can find it on your inverters name plate next to your serial number. 
Assigning "Guest" rights is most useful for displaying the data from the PV system without the ability to change important parameters of the PV system unintentionally. If a different Fronius Solar.web user account should also have access to the settings, we recommend assigning "Plant Engineer" rights.
Please contact our customer services. You can get in touch with us using our contact form. As this involves confidential data, and because changing the e-mail address grants you full access to the associated PV system, we ask that you attach a scan of your valid ID in this case. 

Fronius Solar.web Premium

Fronius Solar.web Premium refers to the upgrade that is available on your Fronius Solar.web user account.

Yes, it is possible to embed the mode in a website. To make this possible, the X-Frame option has been allowed for this special part in the Solar.web portal. For security reasons, the domain that the site wants to use must be entered during activation.
It is not possible to visualize multiple PV systems. The mode can be activated for one PV system. The following alternative can be used: some browsers offer “slideshow” extensions, which allow you to (automatically) switch between open tabs in the browser. Example: https://chrome.google.com/webstore/detail/revolver-tabs/dlknooajieciikpedpldejhhijacnbda
Public Display Mode cannot display other content. 
Yes, if the respective device supports an auto-start function and the link to Public Display Mode is saved as the start page.
Yes, if the respective browser supports full screen mode and this can be called up via the link to Public Display Mode, which is saved as the start page. Example: https://praxistipps.chip.de/windows-10-autostart-programme-hinzufuegen-so-klappts_42165o  “C:\Program Files (x86)\Google\Chrome\Application\chrome.exe” --user-data-dir=c:\temp --start-fullscreen https://www.solarweb.com/PublicDisplay/LogOn?token=4bb83678-2e86-41db-9e5b-72fcabe3a9f0
Public Display Mode can be used on any smart device, but was created specifically for large screens. 
Please check whether there is an active Fronius Solar.web Premium membership in your user account. You can see this in your user settings, for example. 
If the displayed language of Public Display Mode shall be changed, the browser language needs to be changed. After changing the browser language, the Public Display Mode uses the wished language as well.
Public Display Mode allows you to visualize PV systems on large screens based on the system view in Solar.web. Solar.TV offers additional options to configure the contents of the visualization and to select several PV systems. 
Further development of Solar.TV has been stopped, but the platform will still be available for a certain period of time. 
Solar.TV will remain free of charge until it is discontinued.

  • The selection of available warranty extension options did not open automatically? Maintenance work might be in progress. Please retry again later. Should the problem persist please contact our customer service utilising our contact form. Your e-mail address which is linked to your account must be provided.
  • If a Service Process which is related to your inverter is still open, you will not be able to finalise the warranty extension process. You will be able to purchase the warranty extension as soon as the Service Process has been completed. Thank you for your patience.
  • For detailed information on available warranty models, see Fronius Warranty Terms and Conditions.

Your Fronius inverter comes with the Fronius Warranty Plus which you can extend. In order to extend the warranty period you need to sign in to your account and register the Fronius inverter. Once your registration is completed you will be offered various options for the extension of your Fronius inverter. This link may be helpful for the registration process.

The cost of the warranty extensions depends on the inverter type. The price per warranty type will be stated in the overview of available warranty types. You can access this via Solar.web.
Fronius offers two types of warranty extensions. You can either chose the Fronius Warranty Plus which covers the cost of material, labour (service lump sum payment for the exchange by the installer) and freight or the Fronius Warranty which covers the cost of material only. A detailed overview of our warranty types is available on our homepage.
No, after you have purchased a Fronius inverter you are able to claim the free of charge warranty extension on www.solarweb.com. The free of charge warranty extension can only be claimed before the standard warranty period has expired. A purchase of an additional warranty is optional. This link may be helpful for the process.
Yes, you can purchase your warranty direct from your installer. Please contact your installer for further information.
Fronius warranty extensions purchased from your installer have different period of validity than warranty extensions purchased from Fronius on Solar.web. 
Solar.web will always state the current expiry date for your Fronius warranty. In case the warranty expiry date for your Fronius inverter is incorrect please contact our customer service from your e-mail address which is connected to your account utilising our contact form.
In some cases the synchronisation of your warranty cover can take a longer period of time. This will be indicated by the status “Transaction in progress”.
For inverters which have the same prerequisites it is possible to use the collective warranty extension. It allows to add a warranty selection for multiple products simultaneously to the basket.
The warranty which you have purchased for your Fronius Solar Battery covers all modules. In case you extend your Fronius Solar Battery additional modules are covered automatically.
The warranty terms and conditions as well as the options for the extension depend on the country of installation. You will therefore be able to purchase the warranty extension types offered for the relevant country of installation.
A cancellation of the purchase of a warranty extension can be done within the compulsory period for withdrawal of 14 days from purchase. Please contact our customer service utilising our contact form. Your e-mail address which is linked to your account must be provided. Please note the warranty certificate provided upon purchase of the warranty extension will be void upon cancellation. The verification of the warranty period is based on the Fronius system entry only (the Warranty Certificate cannot be used as proof of warranty cover). The current expiry date for your Fronius warranty will always be stated on Solar.web.
The cost of the warranty extension depends on multiple factors. Depending on the market conditions and the economic situation, we have optimized the prices for the warranty extensions for each country. This enables us to offer you the warranty extension for your Fronius inverter at the best possible price.
Please mention that although Fronius Ohmpilot and Smart Meter own a serial number, these devices aren’t approved for the registration in the Solar.web portal. This is due to the fact that neither a warranty extension nor a warranty certificate are available. Your invoice is proof of warranty. 
Since the BYD battery isn’t a Fronius product, it can’t be registered in the Solar.web portal.

The Fronius Wattpilot is an intelligent charging solution for everyone with an electric car. The Fronius Wattpilot is available in two versions - the permanently installed Wattpilot Home for your home and the mobile Wattpilot Go for on the way. The device can be operated via the associated Solar.wattpilot app, which also provides an overview of the charging process. The intelligent plug-and-play charging solution has two different charging modes, the Eco and the Next Trip mode. In addition, the Wattpilot is PV-optimized: The car can therefore be charged with excess solar energy in ampere steps in a particularly cost-efficient and sustainable manner.
In October 2018, the SOLH2UB became the first working pilot system in Austria that generates green hydrogen from solar energy to then be used to refuel hydrogen-powered vehicles on company premises. As a secondary energy source, hydrogen will play an important role in an energy system that is based on 100% renewable sources. Aside from the straightforward (seasonal) storage of excess renewable energy, hydrogen as an energy source has huge potential for energy sector integration (powering the mobility, heating and energy sectors). From the second half of 2019, we will be focusing even more energy on implementing demonstration projects at industrial facilities and for local authorities. We want to be able to offer infrastructure solutions that enable the customer's mobile applications to be operated in an optimal manner. We are also currently researching the area of fuel cells.
If you choose to install the Fronius Ohmpilot, your PV system will no longer supply your house with electricity alone, but will also provide heat, making an additional solar heating system unnecessary. The Fronius Ohmpilot is mainly used to heat water. However, the device can also be used for space heating during transitional periods, as well as heating water. The Operating Instructions for the Fronius Ohmpilot contain additional case studies that you may find useful:
Deviations between the values shown on the inverter display and the values that have been uploaded to Fronius Solar.web can occur due to measuring tolerances. Recent maintenance work may also lead to deviations.
If you would like to buy a PV system, please contact an installer. If you do not know any local companies, you can find your nearest installer using our dedicated search tool.
If you are experiencing problems with your inverter, please contact your installer first, as they will be able to provide on-site support. You can find your nearest installer using our dedicated search tool.

Fronius System Extensions

No, as our platform Solar.web is specialized on visualizing solar energy flows.
No, the Wattpilot has to be deleted from its current PV system in Solar.web before it can be added to another PV system.
Yes, multiple Wattpilots can be added to a PV system in Solar.web.

For Wattpilot data to be displayed in Solar.web, ensure the following:

  • The Wattpilot (as well as your inverter) must be added to your PV system in Solar.web in the tab "Settings" - "Components". If this tab is not visible, please ask your installer to assign you "Owner" or "Supervisor" rights for your PV system.
  • The Wattpilot requires firmware version 36.0 or higher. You can update your Wattpilot in the Solar.wattpilot app in the tab "Internet".
  • The Wattpilot needs to be paired with your inverter. Go to the tab "Settings" - "Cost Optimization" in the Solar.wattpilot app to pair your Wattpilot with an inverter.
  • If the paired inverter is a GEN24 or Tauro, firmware version 1.12 or higher is required. You can update your inverter in Solar.web in the tab "Settings" - "Components".
  • Both the Wattpilot and the paired inverter must be connected to the internet.
If the Wattpilot has no internet connection (e.g. due to weak WLAN), live and history data is not available in Solar.web. History data will not be restored when the Wattpilot reconnects to the internet.Furthermore, Wattpilot data is only shown if the Wattpilot is paired with an inverter of the same PV system in Solar.web. For example, no data is displayed in Solar.web for periods when the Wattpilot Go is used on the go.
When the Wattpilot is handed over to the new owner, the device has to be deleted from the original pv system in Solar.web and has to be added to the new one.
