The GEN24 product family consists of the GEN24 and the GEN24 Plus. The GEN24 is a future-proof inverter (including PV Point basic backup power) in which the battery operation and optionally also Full Backup hybrid functions can be subsequently activated by the installer via the "UP.storage" software upgrade in Solar.web and in the Fronius online store. With the GEN24 Plus, all functions are already available from the moment of purchase. The devices differ purely in terms of software and have the same range of functions with the exception of battery operation and Full Backup. 

Note: The availability of the upgrade program (Fronius UP) differs in different countries. You will find a list of all countries in which a GEN24 can be upgraded to a GEN24 Plus here.

To help prepare you to install and commission the Fronius GEN24 Plus, we have collected all important information and technical details.
This should guarantee the quick and easy installation of your first GEN24 Plus hybrid inverter!

To support you in comprehensively planning and designing PV systems when consulting and providing solutions for your customers, we offer the Fronius Solar.creator as a free, flexible and user-friendly online configuration tool. It can be individually adapted to your needs and, with its numerous functions, offers assistance in all planning stages of your projects.

The Fronius GEN24 & GEN24 Plus can not only be installed in a quick and easy way, but can also be serviced efficiently. In the event of service, the power stage, the data communication unit, the fan or the entire device can be replaced.

To keep the handling of the service case as efficient as possible, the convenient Fronius Solar.SOS service tool supports you. Using the app or 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 gives you the opportunity to easily solve technical problems as well as place orders for spare parts yourself at any time, without having to call the support hotline.

"Forgot password" function on the user interface of the inverter

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:

• On the user interface of the inverter, click on "Forgot password" to generate a PIN.
• On Fronius Solar.SOS, go to "Recovery Key" and fill out the mandatory fields to generate a recovery key.
• On the user interface of the inverter, enter the generated recovery key and set your new password.

Please note: To be able to generate a recovery key, you require supervisor or owner permissions on Solar.web for the device.

Fronius Smart Meter

With the Fronius Smart Meter, the user can not only record data from the system, but also the power consumption in the household and optimize it with intelligent energy management. With the integrated interfaces, Fronius inverters can also be easily integrated into third-party systems. We recommend placing the Fronius Smart Meter in the feed-in point. In addition, further secondary meters can be connected to visualize individual consumers (Fronius Energy Profiling).

Energy profiling

Fronius Energy Profiling allows loads and producers to be measured 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 loads and producers to be displayed on Fronius Solar.web.The number of additional counters 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

Compatible batteries

Fronius GEN24 Plus can be combined with BYD Battery-Box Premium HVS/HVM or LG RESU FLEX.

Backup Power

The Fronius GEN24 Plus Series offer two backup power solutions

PV-Point (for GEN24 and GEN24 Plus):

• 1-phase backup power up to 3 kW
• Backup switchover equipment is already integrated
• The PV Point works even without a battery or Fronius Smart Meter

Full-Backup (for GEN24 and GEN24 Plus):

• 1-phase backup power up to 6 kW (Primo GEN24 Plus) or 3-phase backup power up to 10 kW (Symo GEN24 Plus*)
• Backup power switchover system required (e.g. Enwitec switchover box). The required version must be clarified with the grid operator.
• PV generator, battery and Fronius Smart Meter required.
  
  For both options the switchover from normal operation to backup power takes less than 90 seconds.

Please note:

• The Fronius GEN24 and GEN24 Plus is a grid-connected inverter with a backup power function – it is not a stand-alone inverter. The backup power mode must not be in operation for more than 20% of the duration of the inverter's overall operating hours.
• During normal, grid-connected operation, the GEN24 and GEN24 Pluscan use the excess power of additional AC sources in the system, such as other inverters or generators, to charge the battery. However during backup power operation, no additional inverters or other AC sources (e.g. diesel generators) may feed into the backup power circuit.
  
  *The Full-Backup option is not available for the Symo GEN24 Plus 3 - 5 kW.

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.

Warranty & Firmware Updates

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.
