Product details
Symo GEN24 SC
Symo GEN24 SC is a series of three-phase photovoltaic inverters with power ratings of 3–12 kW, equipped with two maximum power point trackers (MPPT). The built-in PV Point function provides basic backup power, while open interfaces enable integration with components from Fronius and other manufacturers. Active cooling helps extend the inverter’s service life.
Key benefits of Symo GEN24 SC
- Rated AC power 3–12 kW and a maximum efficiency of 98.1–98.3%, depending on the model.
- Two MPPT systems with an operating MPP voltage range of 80–800 V and a DC input voltage range of 80–1000 V.
- Basic backup power supply PV Point as a built-in function of the inverter.
- Protection rating IP66, indoor and outdoor installation and an ambient temperature range from -25 to +60°C.
- WLAN connectivity, two Ethernet LAN ports and two RS485 interfaces; support for Fronius Solar.web, Modbus TCP SunSpec and Fronius Solar API, as well as a built-in data logger and web server.
- Integrated protection: DC insulation measurement, DC disconnector, reverse polarity protection, arc detection and WSD emergency shutdown.
Who is this a good choice for?
Symo GEN24 SC is designed for homeowners looking for an inverter for a photovoltaic system with basic PV Point backup power. Users who need to monitor system operation and integrate additional components benefit from open interfaces, a built-in data logger, and support for Fronius Solar.web.
