Your Fronius user account can be used to log into any Fronius platform. You do not need to create a separate user account.
If you already have a Fronius user account, you can use it to log into the app. If not, you can do so by going to www.solarweb.com and clicking on the ‘Login’ menu item. Should you require additional help with registration, please send details of the error message you have received and the e-mail address you would like to use for your user account to our customer services. To do this, please use our contact form.

Solar.web App
Please click on the plus symbol in the app. This will open the Solar.web page ‘Add PV system’ in your smartphone browser. Alternatively, you can go straight to www.solarweb.com, log in using your user data and then add your PV system. You will then be guided through the process and afterwards you can return to the app. If your system is still not displayed, please contact our customer services using the e-mail address belonging to your user account. To do this, please use our contact form.
There are many reasons why Solar.web may not be receiving data from your inverter. Please go to our PV system support page for useful tips on how to re-establish the data connection. Should you require additional help, please send details of the error message you have received and the e-mail address belonging to your user account to our customer services. To do this, please use our contact form.

You have ‘guest’ rights for the selected Solar.web system. In order to be able to make changes, you need the ‘supervisor’ right. The Fronius Solar.web user account, which has been granted ownership rights to the system, can grant you this authorisation. In most cases, this is your installer.
This shows the current weather in the PV system’s location.
Yes. Click on the system name in the upper section of the app. The PV system selection menu will then open and you can then change between the PV systems. Tip: If you have access to more than five PV systems in your Solar.web user account, you can mark one PV system as your favourite by clicking on the heart symbol next to it.
Battery Control
Battery control gives homeowners the possibility to manually prepare their system for an expected blackout. After the feature is started in the Solar.web-App, the battery is prepared and charging will start. The battery will then be charged up to max SoC (either the one set on the inverter-WebUI or 100%). When the battery is fully charged, it is locked for 24 hours. During this time, discharging is not possible, as the energy is reserved for a possible backup-situation. If the blackout occurs when the battery is full, the energy in the battery can be used to cover the consumption. After the blackout, the battery is kept locked, in case of an additional blackout afterwards. If the battery was still charging, when the blackout occurred, it will continue charging until full afterwards. If the blackout doesn´t occur, the battery is either automatically unlocked after 24 hours, or the user manually unlocks the battery in the Solar.web-App.
No, this feature
is free of charge and will be available for every user with a compatible
system.
No, due to
technical reasons Battery control won´t be available for Symo Hybrids.
If a user
has Supervisor- or Owner-permissions on a system, he/she can see & use
Battery control. If the user is only guest on a system, he / she will see the
status, but can´t start or stop it. Please adapt the permissions on your system
in the Solar.web Portal (Settings -> Permissions) to regulate, who can use
this feature.
This
feature can be activated in the Solar.web-App with GEN24s Plus's, a DC-coupled
battery (all supported batteries are compatible) and a smartmeter. There is no
additional hardware or software / abo needed. The required firmware on the
inverter is on the inverter 1.34.6 or higher.
Yes, the
max. State of charge on the inverter can be used to limit the charging, if e.g.
a customer wants to do only charge it up to 80%. It is recommended to fully
charge up the battery, to have the most energy available in case of a power
outage.
With the activation of Battery control, the battery will be charged with at least 1,5kW, no matter where this energy comes from. This is set to ensure that the imported power is not too high and exceeds the load of the household-fuses on the switchboard. A feature to manually set the grid charging power is already planned.
If the PV-surplus exceeds 1,5kW, only the PV-surplus is used to charge the battery.
The law states, that as soon as "grey" electricity is charged into a battery, the system loses the EEG tariff when it is priced out.
Exceptions:
The system
is outside the EEG, e.g. takes part directly in the market or the discharge is
confirmed via the storage guideline in accordance with VDE 2510-2.
What is required for the usage of Battery
control:
An EnFluRi
sensor (“Energieflussrichtung” sensor) that meets the requirements of the FNN
guideline on electricity storage is required so that the battery can be charged
from the grid. This ensures that the electricity fed in/stored is correctly
allocated. Then charging the battery from the grid is also officially permitted
for EEG remuneration. Fronius is working on a solution for this.
Our energy balance is a visualization that has been optimised to analyse what happens with PV production or the surplus and how the consumption is covered. Charging from the grid was deliberately excluded here at the time, as this was not relevant in a classic self-consumption-optimising system until now. The energy is counted as consumption, when it is discharged from the battery.
Fronius is working on a new view that makes this more transparent, clearly shows when a battery is being charged from the grid and is therefore more future-proof. As of now these flows can be monitored in the History chart in the Solar.web Portal using the ‘Energy from grid’ channel.
