Fronius Reserva BMS + Base AUS-NZ

About This Product

The Fronius Reserva BMS + Base AUS-NZis the control and communication hub required for building a Fronius Reserva energy storage system in Australia and New Zealand. It manages the connection between Reserva battery modules, monitors system behaviour, balances cells, and ensures all components operate within safe limits. The Base provides the mechanical and electrical foundation for stacking battery modules, while the BMS handles configuration, protection, and communication with the connected inverter.

Who This Product Suits

• Homeowners and installers building a new Fronius Reserva battery stack for hybrid or backup applications.
• Sites using Fronius GEN24 or Fronius hybrid inverters that require tight communication and full compatibility with Fronius’ energy management features.
• Customers wanting a modular storage system where capacity can be added by stacking additional battery modules onto a stable base.
• Installers who prefer brand-matched battery ecosystems with straightforward commissioning and integrated safety controls.

Specifications Explained

• BMS (Battery Management System):Oversees cell balancing, temperature monitoring, charge/discharge control, and system protection for all connected Reserva battery modules.
• Base Unit:Provides the mechanical support and electrical interface for stacking and connecting multiple Reserva modules in a compliant vertical stack.
• Integrated Communication:Communicates with Fronius hybrid inverters, enabling coordinated charge/discharge, backup behaviour, and energy management functions.
• System Safety Functions:Includes protections for overvoltage, undervoltage, overcurrent and temperature limits, ensuring stable long-term operation.
• Modular System Architecture:Designed for use as the required first component in any Reserva battery stack for the AU/NZ region.

Summary

The Fronius Reserva BMS + Base AUS-NZis the essential starting point for any Fronius Reserva battery installation. It houses the system’s protection and control electronics and provides the stable foundation for adding battery modules. When paired with Fronius hybrid inverters, it delivers a tightly integrated, fully brand-matched storage solution suitable for Australian and New Zealand installations.

Further Information From The Manufacturer

Converting solar energy, controlling, distributing and using solar energy – and now also storing solar energy: With the Fronius Reserva, the Austrian provider of solar electronics completes its product portfolio.

The Fronius Reserva is a high-voltage battery with DC coupling that guarantees almost loss-free charging and discharging performance. Capacities between 6.3 and 15.8 kWh are possible with two to five modules. The storage modules are stacked on top of each other like building blocks as a plug-and-play connection without the need for cabling. A total of up to four battery towers can be connected in parallel to achieve a maximum storage capacity of 63 kWh. The new battery storage system is optimally matched to the two hybrid inverters Fronius GEN24 Plus and Fronius Verto Plus and can therefore be seamlessly integrated into an existing photovoltaic system. The tried-andtested Solar.web app is all that is needed for visualization; no additional software is required. The Fronius Reserva status display also shows the current charge status and indicates if there is a fault.
