About This Product

The Fronius 15.79kWh Three Phase Reserva Module AUS-NZ is a high-voltage lithium iron phosphate (LFP) battery module designed for use within the Fronius Reserva energy storage system. It is purpose-built for Australian and New Zealand three-phase installations and integrates directly with compatible Fronius hybrid inverters for seamless solar storage.This module forms part of a scalable battery stack, allowing installers to configure total storage capacity to suit site requirements. It is engineered for grid-connected residential and small commercial systems where reliable energy storage, solar self-consumption, and backup capability are required.Designed for clean indoor installation, the module features integrated battery management for safe operation, long service life, and stable performance under Australian conditions.

Who This Product Suits

This module suits homeowners and small commercial customers with three-phase power who want to store excess solar energy for evening use or backup supply.It is well suited to:

• Three-phase homes with higher energy consumption
• Properties installing a compatible Fronius hybrid inverter
• Customers wanting modular battery expansion over time
• Installations requiring compliant AUS-NZ certified equipment

It is ideal for customers wanting a fully integrated Fronius ecosystem rather than mixing multiple brands.

Specifications Explained

The Fronius Reserva module uses lithium iron phosphate (LFP) cell chemistry, chosen for its thermal stability, long cycle life, and safety characteristics.Key technical features include:

• Nominal energy capacity of 15.79kWh per module
• High-voltage DC battery architecture for efficient inverter integration
• Integrated battery management system (BMS) for cell monitoring and protection
• Modular stack design for scalable total system capacity
• Designed for three-phase hybrid inverter compatibility
• AUS-NZ compliant configuration

The high-voltage design reduces current flow compared to low-voltage systems, which improves efficiency and allows cleaner integration with modern three-phase hybrid inverters.

Summary

The Fronius 15.79kWh Three Phase Reserva Module AUS-NZ is a modular, high-voltage LFP battery designed for integration with Fronius hybrid systems in Australia and New Zealand.It provides scalable energy storage for three-phase homes and small commercial sites, supports solar self-consumption, and enables backup-ready system design when paired with compatible hardware. For installers wanting a consistent Fronius-based solution, this module forms a solid foundation for a compliant and expandable battery system.

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. The storage modules are stacked on top of each other like building blocks as a plug-and-play connection without the need for cabling. 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.

Bundle Includes:

• 5 x Fronius 3.15kWh Reserva Module AUS-NZ
• 1 x Fronius Reserva BMS AUS-NZ
