Inverter – FRONIUS – Symo GEN24 3.0 Plus – hybrid – HV
Product details
Symo GEN24 & GEN24 Plus
Symo GEN24 & GEN24 Plus is a series of Fronius photovoltaic inverters with power ratings of 3–10 kW, comprising standard and hybrid versions with an energy storage connection. The integrated PV Point function provides basic backup power, while open communication interfaces enable the integration of components from Fronius and third-party suppliers. The hybrid version with energy storage allows energy from the photovoltaic system to be used at night as well.
Key benefits of Symo GEN24 & GEN24 Plus
- Power 3–10 kW and two MPP trackers — the series offers a usable MPP voltage range of 80–800 V and a startup voltage of 80 V.
- PV Point backup power — the basic function is integrated into the inverter. The Full Backup option is available only in the Plus version rated at 6–10 kW and enables the entire household to be powered.
- Compatibility with energy storage — the Plus version has a battery storage connection. The Fronius UP.storage update enables the standard version to be upgraded to support energy storage; the solution is available in selected countries through the Fronius online store.
- Open interfaces and energy management — allow components from Fronius and third-party suppliers to be integrated and the photovoltaic system to be tailored to the user’s needs.
- Active cooling — the built-in system extends the device’s lifespan.
- Protection rating IP66 — the inverters are designed for indoor and outdoor installation, at ambient temperatures from −25 to +60°C.
Who is this a good choice for?
The series is designed for homeowners who want to use a photovoltaic system with basic backup power. The hybrid version meets the needs of users planning to store energy and use it at night, while the Plus variants rated at 6–10 kW also offer the option of full home backup power. Open interfaces will appeal to those who want to combine components from Fronius and third-party suppliers in a single system.
