Fronius Reserva
Store solar energy and reduce costs
Unlock the full potential of your PV system: With the Fronius Reserva, the solar energy you generate is stored for when you need it most — in the evening or on cloudy days. This means less reliance on the grid, lower energy costs, and greater energy independence.
Fronius Reserva – your solution for efficient energy storage
The Fronius Reserva is a DC-coupled high-voltage battery that stores excess solar energy with outstanding efficiency. Available in capacities from 6.3 to 15.8 kWh (two to five modules), it scales to match your individual energy needs. It integrates seamlessly into your existing Fronius system and pairs perfectly with your Fronius hybrid inverter. Thanks to DC coupling, energy conversion losses are minimized — for maximum efficiency and higher self-consumption. This helps you cut energy costs significantly and boosts your independence from the grid.
Built with durable, safe lithium iron phosphate cells and designed for flexible expansion, the Fronius Reserva is your reliable and future-ready energy storage solution.
