Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The announcement publishes a range rather than a named reviewed configuration, so the score anchors to the smallest published tower rather than the largest stack, and the evidence scope records that it is an announced range rather than an exact configuration. Scored model: Reserva Pro (smallest published tower configuration, 12 kWh) · checked 2026-08-18. Evidence.
Sources & references · checked 2026-09-02
Strong evidence coverage
3 of 3 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.
Record revision. Fronius Reserva Pro announcement of 17 March 2026, checked 2026-08-18. India existing-catalogue battery review 2026-09-02: IN overlays recorded from manufacturer Indian catalogues; scores unchanged.

IN Support Note
- Before
- Not previously recorded
- 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.
