Fronius
Primo GEN24 Plus
Single-phase hybrid inverter line for North America with residential classes from 3.8 kW, now built in Indiana. The Plus version is battery-ready with backup via PV Point (a powered outlet that works whenever the sun shines, even without a battery), plus string-level shade optimization.
The core fronius integration polls the inverter's Solar API over Wi-Fi or Ethernet: PV power, grid import/export via the Fronius Smart Meter, and battery state of charge on hybrid setups, all local. On GEN24 firmware 1.14.1 and newer the Solar API ships disabled: enable it once in the inverter's web interface during commissioning. Platinum quality-scale integration in Home Assistant.
