The verdict. In our Performance & Value class, Fronius Reserva Pro leads on safety & chemistry. Home-battery reliability is rarely independently verified, so judge on chemistry, safety certification and the backing company.

Pre-market release. Not all data is sourced or available. The assessment now uses Reserva Pro 12.0: three modules, 11.9 kWh usable and 12 kWh nominal. The exact usable range is 11.9-31.9 kWh per tower; four largest towers provide 127.6 kWh aggregate battery energy before conversion. The former 28.3 kW system headline is not scored as continuous output for the smallest tower; an exact continuous rating remains unverified. Current manual temperature limits include strong derating above 48C, and IP65 installation is limited to protected outdoor or indoor locations. AU approvals cover six named models through 31 December 2027. Manufacturer October 2026 launch evidence does not verify stock or deliveries. Governing Australian warranty remains held because AU75% and global 80% retention headlines differ; full product-depth review remains incomplete. Criteria with no exact-product source are withheld and scored at the non-disclosure floor, so this score measures what is documented today rather than how the product performs. It will move as the manufacturer publishes.

Strong evidence coverage

4 of 4 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

    The CER battery CSV published 2 October 2026, read 5 October, lists Fronius International GmbH / Fronius / Reserva Pro models 12.0, 16.0, 20.0, 24.0, 28.0 and 32.0: approved 9 September 2026, listed expiry 31 December 2027. Model 12.0 is 12 kWh nominal and 11.9 kWh usable. This is exact battery-list evidence; it does not establish inverter or site approval.; The Fronius Australia Reserva Pro product page, read 7 October 2026, lists VDE2510-50 / IEC 62619:2022 / IEC62040-1 / CE / RCM / UN38.3 as certifications and compliance. This is a maker-declared list; no certificate or test report for the exact model was read, and it does not replace the CER battery approval above.

    Current Fronius Australia product page states availability from October 2026. The 2 October CER export, read 5 October, lists all six exact Reserva Pro 12.0-32.0 models with approval on 9 September 2026 and expiry on 31 December 2027; the August non-listing observation is superseded. Actual stock and deliveries are not verified. Governing Australian warranty conditions remain unresolved: the current AU page gives 10 years / 75% SOH, while the global EN_V02 Jan 2026 datasheet gives 80% SOH. Neither headline substitutes for the governing instrument. Exact scored configuration is now Reserva Pro12.0, three modules and11.9kWh usable (12kWh nominal). The28.3kW system maximum is withdrawn from scoring; exact continuous output remains held.
