To be well prepared for the installation and commissioning of a Verto, we have summarized all the important information and technical details for you. This ensures that nothing stands in the way of a quick and easy installation of your first Verto inverter!
|
Software Update Please ensure that your Verto always has the latest software version. This can be installed in Solar.web under Settings – Components. |
Don't forget to bring your trusty Torx 20 screwdriver. All screws are easy to attach with a quick-release system, meaning you only need to turn the screw 180° to fasten it.
Please note: do not turn the screws more than 180° and do not use an electric screwdriver.
How-To Video: Installation Fronius Verto
Start up your Verto with a smartphone on which the Fronius Solar.start app is installed.
Just as with the commissioning of other Fronius inverters, such as the Fronius GEN24, the app guides you through the process and helps you to easily connect the inverter to the internet.
Alternatively, you can also use your browser for commissioning. We recommend bringing a tablet or laptop for this. Connect your device to the inverter's WiFi access point and enter the following IP address in the address bar of your browser: 192.168.250.181
Please note:
The Fronius Verto comes with integrated surge protection (SPD) as standard. When placing the order, you can choose between two options:
The Fronius Verto has 4 MPP trackers with 2 inputs each. Module strings of identical length can either be split between the two inputs of an MPP tracker or merged before that and connected to just one input. Please pay attention to the maximum permissible currents per MPP tracker (IDC max, MPPT) and per input (IDC max, string) specified in the data sheet.
The maximum usable input currents IDC max, MPPT and IDC max, string specified in the data sheet may be exceeded without violating the manufacturer's warranty. If these are exceeded, it should be noted that the inverter actively limits the current to the specified value. Accordingly, slight yield losses are to be expected.
The maximum short-circuit current of the module strings must not exceed the values specified in the data sheet for each MPP tracker (Isc pv, MPPT), for each string (Isc pv, string) and for the total short-circuit current (Isc pv, inverter), otherwise the device may be damaged!
DC power optimisers adjust the voltage of shaded PV modules by increasing or decreasing it. The more shade there is, the higher the optimiser's consumption and the lower its efficiency. This means that, especially in the case of partial shading, the power optimisers often cannot compensate for the shading and thus do not increase the yield.
Compatibility with power optimisers is not confirmed for the Verto inverter series.
The ‘Fronius Arc Guard’ safety function is used to detect and interrupt DC electric arcs in PV systems. The function was developed to comply with the IEC 63027 standard. It deals with the technical requirements for ‘Arc Fault Protection Equipment’ (AFPE) and ‘Arc Fault Circuit Interruption’ (AFCI) in photovoltaic systems.
Fronius Arc Guard is always integrated into Verto inverters, but is disabled by default. If required, the function can be activated on the inverter user interface. The procedure is the same as for the Fronius Tauro.

The Fronius Verto offers a range of functions and interfaces for system monitoring, energy management, connecting to third parties and export limitation. These functions are described below.
Please note:
Fronius Solar.web is fully available as a website and app for monitoring your Verto inverters.
You can download the Solar.web app to your smart device from your App Store and the Google Play Store!
If there are any issues with data transmission to Solar.web, please check our Help with Data Transmission Issues.
The Fronius Verto offers 4 digital outputs for intelligent load management, allowing devices such as heat pumps, heating elements, or pool pumps to be controlled. In the download area, you will find a whitepaper that contains more information. The whitepaper describes the GEN24 but is equally valid for Verto.
Fronius also offers sector coupling solutions for hot water preparation with the Fronius Ohmpilot and an e-mobility solution with the Fronius Wattpilot.
With its open interfaces, the Fronius Verto can be easily connected to a variety of third-party components such as heat pumps, smart home systems, or charging solutions for electric vehicles. On the Third-Party Compatibility page, you will find the current list of all compatible third-party components for the Verto, which is constantly being expanded.
The settings for the open interfaces can be found on the inverter's user interface under "Communication".
Software updates for the Verto can be conveniently carried out from home via Fronius Solar.web. This way, you always have the latest compatibility with third-party components available.
You can activate dynamic power reduction in the Fronius Verto user interface under ‘Safety and Grid Regulation’ - ‘Feed-In Limitation’ to limit the power fed into the grid and at the same time maximise direct self-consumption. This can also be used for zero-feed-in systems.
A Fronius Smart Meter is required to use this function.If you have installed one or more Verto in combination with other Fronius inverters in a system and want to set a feed-in limitation, please refer to the installation instructions. You can find the installation instructions in the download area.
The Fronius Verto is not only quick and easy to install, but also efficient to maintain. When servicing is required, the data communication unit, the integrated surge protection or the entire device can be replaced.
The convenient Fronius Solar.SOS service tool helps you to make servicing as efficient as possible. With the app or the browser version, you can initiate the service process online directly at the system location. All you need is a serial number or a state code. This enables you to easily solve technical problems and order spare parts yourself at any time without having to call the support hotline.

The local user interface of the inverter is protected by a Customer password and a Technician password.
With the function "Recovery Key" in Fronius Solar.SOS you can generate the recovery key to reset the Customer or Technician password of your device.
The password can be reset as follows:
Please note: To be able to generate a recovery key, you require supervisor or owner permissions on Solar.web for the device.

With Fronius Energy Profiling, it is possible to measure consumers and producers with more than one meter: In addition to the primary Fronius Smart Meter, further secondary Fronius Smart Meters can be connected via Modbus RTU. This allows the measured consumers and producers to be displayed on Fronius Solar.web. The number of additional meters that can be connected depends on how many devices are already connected to the Modbus interface. The manual with detailed explanations can be found in the download area.
Please note: All Fronius Smart Meters, regardless of version or age, can be combined in one system to enable energy profiling.
Following a quick and free registration process at www.solarweb.com, owners of a Fronius product can select an attractive warranty model, depending on their region, that perfectly matches their individual requirements.
Every GEN24 has a verification code (V.Code) in addition to the serial number. The V.Code is intended to avoid possible mix-ups or misuse during product registration. You can find both numbers on the name plate of the inverter. They are mainly required for product registration and to add the system to Solar.web. Detailed instructions for product registration can be found here.
Please note: The product registration must be completed within 2 years of the system installation and the warranty options available vary between regions.
The inverter firmware must be regularly updated in order to ensure smooth operation of the photovoltaic system. Ongoing inverter software updates not only guarantee a low failure rate and better serviceability of the device, they also ensure optimal system performance.
Regular firmware updates of the Fronius GEN24 inverters are therefore a prerequisite to ensure full validity of the Fronius warranty.For further information on updating your inverter, please refer to Firmware & Software.
