The verdict. In our Performance & Value class, Fronius Reserva Pro leads on guarantee & backbone. Home-battery reliability is rarely third-party 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

15 of 15 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 a guarantee that a claim is correct.

How far the evidence reaches

None of the 5 questions with checkable rows has a row beyond the maker's claim.

  • Output1 checkable row, a reviewed absence: not published, we lookedMaker-only: 2 design facts2 held rows, not scored
  • Endurance1 checkable row, a reviewed absence: not published, we lookedMaker-only: 4 maker's commitments, 1 design fact
  • Safety1 checkable row, not beyond the maker's claimMaker-only: 1 design fact
  • Backing2 checkable rows, none beyond the maker's claimMaker-only: 1 maker's commitment
  • Fit1 checkable row, not beyond the maker's claim1 held row, not scored
  • FootprintNot scored for batteries
  • Third-party source
  • Certified or regulator-listed
  • Manufacturer claim
  • Reviewed absence

Each bar is one question's checkable rows for this product at true share, stronger tiers first; hatching marks a reviewed absence: not published, we looked. Maker-only rows (warranty terms and design facts that rest on the maker's own documents) are counted under each question, never dropped. Held rows have no value, and each says why: not yet confirmed for the exact product, published but not matched to a rubric band, set by paired equipment, or not applicable. They are not scored and are counted under each question, never drawn. review.solar has measured none of these rows itself. How the evidence puzzle works

    After
    The exact scored model Reserva Pro is not named on Fronius India's inverter and storage-unit catalogue. India has no public per-model BIS register, so registration is not independently verified here. Absence from that catalogue is a listing fact, not a quality finding, and does not change the global score. That catalogue names Primo, Primo GEN24, Symo, Symo GEN24, Tauro, Tauro Eco and Eco. Reserva Pro is not among them and is not transferred. Reserva 6.3 is a different identity and is not transferred. Existing AU, US or DE warranty terms are not transferred.
