Bring solar generation, battery storage and intelligent energy management together with the Fronius Symo GEN24 Plus, a premium Austrian-made hybrid inverter range available in 5kW, 6kW and 8kW models.
Designed for households seeking greater energy independence, the Symo GEN24 Plus combines flexible PV design, direct high-voltage battery integration, intelligent backup options and smart monitoring in one advanced platform. Dual MPP tracking helps maximise solar yield across different roof orientations, while Fronius Active Cooling and IP66 protection support reliable long-term operation in demanding residential environments.
The Fronius Symo GEN24 Plus range is well suited to:
Residential solar and battery systems
Homes seeking higher solar self-consumption
Properties with multiple roof orientations
Households planning for battery storage
Homes requiring basic or expanded backup capability
EV charging and smart energy applications
High daytime electricity consumption
Indoor and outdoor residential installations
The Fronius Symo GEN24 and Symo GEN24 Plus share the same core three-phase platform. The main difference is battery functionality.
The Symo GEN24 is primarily a solar inverter with PV Point basic backup, while the Symo GEN24 Plus is the hybrid version with battery connection enabled and support for Full Backup on compatible models when paired with a suitable battery and the required switching equipment.

Fronius Reserva and selected BYD battery compatibility
Made in Austria
Two independent MPP trackers allow the Symo GEN24 Plus to manage separate PV arrays efficiently, making it well suited to homes with different roof orientations or more complex solar layouts.
Maximum supported PV generator capacity varies by model:
Symo GEN24 5.0 Plus β up to 7.5kWp
Symo GEN24 6.0 Plus β up to 9kWp
Symo GEN24 8.0 Plus β up to 12kWp
A wide 80β1000V DC input range and 80β800V usable MPP range give installers broad flexibility when designing the PV system.
The Symo GEN24 Plus is designed as a true hybrid inverter, allowing a compatible high-voltage battery to connect directly to the system.
Battery operation is supported across a 160β700V DC range, enabling excess solar energy generated during the day to be stored and used later when household demand increases or solar production falls.
Compatible battery solutions include Fronius Reserva and selected BYD Battery-Box Premium HVS/HVM systems.
All three models include Fronius PV Point, providing up to 3,000VA of basic backup power through a dedicated single-phase connection.
This allows selected essential loads to remain powered during a grid outage when sufficient energy is available.
For broader backup requirements, the 6kW and 8kW GEN24 Plus models also support Full Backup:
Symo GEN24 6.0 Plus β up to 6,000VA Full Backup output
Symo GEN24 8.0 Plus β up to 8,000VA Full Backup output
Full Backup switching time is less than 10 seconds and requires additional external components for grid switchover. The 5.0 Plus supports PV Point but not Full Backup.
The Symo GEN24 Plus is engineered to convert solar energy efficiently across a wide range of operating conditions.
| Model | Maximum Efficiency | European Efficiency |
|---|---|---|
| GEN24 5.0 Plus | 98.2% | 97.5% |
| GEN24 6.0 Plus | 98.2% | 97.7% |
| GEN24 8.0 Plus | 98.2% | 97.8% |
MPP adaptation efficiency exceeds 99.9% across all three models, helping the inverter continuously track the most productive operating point of the solar array.
Fronius Active Cooling technology actively manages internal temperature to help protect electronic components from excessive heat.
By reducing thermal stress, the system supports consistent output and long-term reliability across an ambient operating range of -25Β°C to +60Β°C.
Fronius Solar.web gives homeowners and installers clear visibility over solar production, battery operation and overall system performance.
Remote access helps make it easier to review operating data, identify optimisation opportunities and respond to potential issues without needing to be physically at the inverter.
Connectivity includes:
WLAN
2 Γ Ethernet LAN
2 Γ RS485
Fronius Solar.web
Modbus TCP SunSpec
Modbus RTU SunSpec
Fronius Solar API
Integrated datalogger
Integrated web server
6 digital inputs
6 digital inputs/outputs
Integrated emergency shut-off
Β
Open communication interfaces allow the GEN24 Plus to integrate with compatible Fronius products and supported third-party components.
This makes it possible to build a broader home energy system around solar generation, battery storage, smart metering, heating and EV charging, helping households use more of their own renewable energy and reduce dependence on grid electricity.
The Symo GEN24 Plus features an IP66 enclosure suitable for both indoor and outdoor installation.
Integrated protection functions include:
DC isolation measurement
Integrated DC disconnector
Reverse-polarity protection
Integrated emergency shut-off
Safety Class 1
The inverter supports 0β100% permissible humidity and operation at altitudes up to 3,000m without voltage-range restrictions.
