Product description

The Fronius Reserva is a DC-coupled high-voltage battery for home PV storage, paired with a Fronius Primo GEN24 Plus SC, Symo GEN24 Plus SC or Verto Plus hybrid inverter. It scales in 3.15 kWh module steps across four sizes — 6.3, 9.5, 12.6 and 15.8 kWh — and up to four towers run in parallel for as much as 63 kWh (identical module count per tower; the 32 A system limit means parallel towers add capacity, not power). DC coupling stores solar energy with minimal losses, and backup power is available via on-board PV Point (single-phase up to 3 kW), PV Point Comfort, or Full Backup for the whole home using the Fronius Backup Controller or Backup Switch (Full Backup requires a battery plus switching components; PV Point is not available on Verto Plus). Monitoring is via Solar.web, and with Solar.web Premium the Energy Cost Assistant optimises charging against dynamic tariffs. Battery efficiency 95%, IP65, −20 °C to +55 °C, 10-year warranty.
