Product details
Symo GEN24
Symo GEN24 is a series of Fronius photovoltaic inverters rated from 3–10 kW, featuring an integrated PV Point basic backup power function. Open communication interfaces enable the integration of components from Fronius and third-party suppliers, while energy management functions help save time and costs. Active cooling extends the service life of the device.
Key benefits of Symo GEN24
- Integrated PV Point – basic backup power available as standard.
- Two maximum power point tracking (MPP) systems – the usable MPP voltage range is 80–800 V.
- Open communication interfaces – allow components from the manufacturer and third-party suppliers to be integrated into the system.
- Active cooling and energy management – solutions that extend inverter lifespan and save time and costs.
- Protection rating IP66 – suitable for indoor and outdoor installation and an ambient temperature range of -25 to +60 °C.
- Option to connect an energy storage system later – thanks to the Fronius UP.storage software update, available in selected countries through the Fronius online store.
Who is this a good choice for?
Symo GEN24 is an option for homeowners with a photovoltaic system who want basic PV Point backup power and energy management. It is also suitable for users planning to integrate additional components or postponing the decision on battery storage, subject to the availability of the Fronius UP.storage upgrade in their country.
