Australia’s solar market is one of the most advanced in the world, and more households are now looking for reliable battery storage to maximise their solar investment. Enter the Fronius Reserva, the newest high-performance solar battery storage system from Fronius, designed to give you complete energy independence, resilience, and peace of mind.
With over 80 years of global expertise and more than 15 years of local commitment in Australia, Fronius is known for its innovation and its “24 hours of sun” vision, a future where renewable energy powers our world. The launch of the Reserva battery completes this vision, allowing Australians to generate, store, and manage their solar energy with one fully integrated solution.
Why Choose the Fronius Reserva Battery?
The Fronius Reserva isn’t just another solar battery. It’s a smart, scalable, and resilient energy solution designed with Australian conditions in mind. Here’s why it stands out:
- One brand, one solution: Fronius now delivers a complete energy system, from inverter to battery and EV charging, all designed to work seamlessly together.
- Built for extreme climate conditions: slimline design (just 17.6 cm thin), weatherproof (IP65), and tested to withstand extreme heat and humidity from Queensland to Western Australia.
- Scalable storage: available in 6.3 to 15.8 kWh sizes, expandable up to 63 kWh by connecting multiple battery towers. Perfect for both homes and small businesses.
- Safe, sustainable chemistry – lithium iron phosphate (LFP) cells provide excellent thermal stability, long lifespan, and are cobalt-free.
- Simple system monitoring – managed entirely through one app, Fronius Solar.web, with secure European servers for data protection.

Smarter Integration with Fronius Inverters
At the heart of every solar system is the inverter, converting solar power into usable energy for your home or business. The Reserva battery integrates seamlessly with the Fronius Primo GEN24 Plus (single-phase), Symo GEN24 Plus (three-phase), and the upcoming Verto Plus hybrid inverters.
Because everything is designed by Fronius, customers benefit from:
- Fewer conversion losses (thanks to DC-coupled technology).
- Optimised system efficiency and longevity.
- Streamlined installation with modular, stackable design, no complex wiring required.
- Simple service and support, one contact for all system components.
Energy Security Where It Matters Most
For many Australians, the biggest benefit of battery storage is energy resilience. Power outages are becoming more common, whether due to storms, heatwaves, or grid instability. The Fronius Reserva ensures your home stays powered when you need it most, while reducing reliance on the grid and cutting energy costs.
As Roland Resch, Managing Director of Fronius Australia, explains:
“We want our customers to be able to rely on their system not only for sustainability and savings but also for energy security.”
