Fronius Reserva batteries

Fronius Reserva Battery
Imagine running your home or business on solar power even after daylight fades. Sounds good, right? With Mode Energy, you can have your Fronius Reserva installation to store your own clean energy and use it anytime you need. For Tasmanian households and commercial energy systems in Launceston, this is such a practical way to take charge of electricity use and rely less on the grid.
Designed by Fronius, who is a global leader in solar technology, the Reserva delivers efficient and long-lasting performance. Its DC-coupled setup allows the transfer of energy between your panels and battery with very little loss, so you make the most of every ray of sunlight that hits your roof.
Why Choose the Fronius Reserva?
Firstly, the Fronius Reserva brings flexibility to solar storage. It has a modular design, which means you can expand your energy storage as your needs grow. It can be paired with the Fronius GEN24 Plus hybrid inverter for a smooth operation and a more efficient performance. Aside from that, if you combine it with a Fronius Backup Controller, it can also supply power even during power outages.
Backup Power Capability
Thanks to its built-in backup and black start features, the Reserva can continue to charge and discharge even during power cuts. As such, it keeps essential power when you need it most.
Status Display
The Reserva has a simple visual indicator that shows the battery’s charge and performance instantly so you can easily monitor and manage the system.
Guaranteed Performance
Each battery unit is supported by a 10-year warranty and the trusted quality assurance of Fronius’ reputation for durability and reliability.
Slim, Space-Saving Design
The Fronius Reserva features a compact and stylish shape that can fit into nearly smaller space like garages or sheltered outdoor areas. It is also designed for Tasmanian weather and performs consistently in temperatures ranging from -20°C to +55°C and can be installed at altitudes up to 2000 metres.
Maximum Adaptability
Each battery module allows you to combine two to five units between 6.3 and 15.8 kWh per tower. If you need more capacity, you can have up to four towers operating together to provide as much as 63 kWh of total capacity.

Smart Technology and System Control
In order to easily monitor energy production, consumption, and storage in real-time, the solar.web monitoring platform can be used. For installers, the Solar.SOS service is available to provide 24/7 support and easy troubleshooting.
Keeping Your Solar Data Private
All system information connected to Fronius devices is stored securely on European services and protected under ISO 27001-certified standards. Furthermore, regular audits and secure coding practices are being done to protect your data at every level. This ensures your solar information stays safe and remains under your control.

Save More with the Cheaper Home Batteries Program
The Australian Government’s Cheaper Home Batteries Program is making solar storage more affordable and accessible for Tasmanians. When you add a Fronius Reserva battery to your solar setup, you are qualified for government rebates that reduce the upfront cost of installation. Each extra kilowatt-hour of battery capacity you add increases your eligibility for rebates and and what’s even greater is that this helps your system pay for itself sooner.
The Fronius Reserva is perfect for this program, and now is the time to take charge of your electricity use and maximise your solar investment. Contact us at Mode Energy, and we’ll help you create a cleaner and smarter energy solution for your home or business.
