Inverter – FRONIUS – Symo GEN24 12.0 Plus SC – hybrid – HV
Product details
Symo GEN24 SC
Symo GEN24 SC is a three-phase photovoltaic inverter with a rated output power of 12 kW, equipped with two MPP trackers. The built-in PV Point function provides basic backup power, while open communication interfaces enable integration of components from Fronius and third-party suppliers. Active cooling extends the device’s service life.
Key benefits of Symo GEN24 SC
- Output power 12 kW and the option to connect a photovoltaic array with a maximum capacity of 18 kWp.
- Two MPP trackers with a usable voltage range of 80–800 V and maximum usable input currents of 28 A and 14 A.
- Basic backup power supply PV Point with a rated output power of 3000 VA, a single-phase 220/230 V output and a switching time of approximately 15 seconds.
- Maximum efficiency 98.2% and a European efficiency of 97.9%.
- WLAN communication, two Ethernet LAN ports and two RS485 interfaces and an integrated data logger and web server.
- IP66 protection rating and active cooling — installation inside and outside buildings and an ambient temperature range from -25 to +60°C.
Who is this a good choice for?
Symo GEN24 SC is an option for homeowners with a photovoltaic system who need basic PV Point backup power. It is also suitable for PV system users who want to integrate components from Fronius and third-party suppliers and access data through extensive communication interfaces.

Energy storage and Full Backup functions are available only with GEN24 Plus. Full Backup requires additional external switching components. Charging power and battery DC power depend on the connected battery; compatibility depends on its type, capacity class, certification and availability in the country concerned.
