The Fronius Reserva is a high-voltage home battery with DC coupling, matched to Fronius hybrid inverters. With capacities from 6.3 to 15.8 kWh with two to five modules, it adapts to your needs.
Thanks to DC coupling, the energy from your solar panels is charged into the battery with almost no loss. Combined with the Fronius GEN24 Plus, it makes the most of even short windows of sunshine, and its lithium iron phosphate cells are built to last.
