Product details
Primo GEN24 & GEN24 Plus
Primo GEN24 & GEN24 Plus is a series of transformerless Fronius photovoltaic inverters with power ratings of 3.0–6.0 kW, comprising a standard version and a hybrid version with the option to connect an energy storage system. The integrated PV Point function provides basic emergency power, while the Plus version also offers a full home backup power option. Open communication interfaces enable integration with Fronius components and devices from other manufacturers.
Key benefits of Primo GEN24 & GEN24 Plus
- Backup power: basic PV Point function as standard and optional Full Backup power in the Plus version.
- Compatibility with energy storage: the Plus version allows stored energy to be used at night as well and increases self-consumption of electricity.
- Maximum efficiency 97.6%: European efficiency ranges from 96.8–97.2% depending on the model, and each variant is equipped with two maximum power point (MPP) trackers.
- Communication and energy management: WLAN, two Ethernet LAN ports and two RS485 interfaces, as well as an integrated data logger and web server.
- Active cooling and IP66 protection rating: suitable for indoor and outdoor installation at ambient temperatures from −40 to +60°C.
- Integrated protection: DC insulation resistance measurement, DC disconnector, reverse polarity protection and WSD emergency shutdown switch.
Who is this a good choice for?
The series is designed for homeowners with photovoltaic systems who need basic backup power and integration with energy management devices. The Plus version meets the needs of households planning to connect a battery storage system, use solar energy at night as well, and optionally provide full backup power for the home.
