No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.

Market context

Global evidencechange in the site menu

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The score uses the highest exact current power bin named on the SOFAR India product catalogue V1.5. Website-only 3.68, 4.6 and 5.5 kW bins are not scored. HYD 6000-ES is a different identity. Scored model: HYD 6000-EP · checked 2026-09-02. Evidence.

Strong evidence coverage

25 of 25 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.

  • Output4 checkable rows, none beyond the maker's claim
  • Endurance2 checkable rows, none beyond the maker's claimMaker-only: 2 design facts
  • Safety2 checkable rows, none beyond the maker's claim
  • Backing1 checkable row, not beyond the maker's claimMaker-only: 2 maker's commitments
  • Fit6 checkable rows, none beyond the maker's claimMaker-only: 6 design facts
  • FootprintNot scored for inverters
  • 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. review.solar has measured none of these rows itself. How the evidence puzzle works

Record revision. SOFAR India product catalogue V1.5 (31 July 2025); India factory warranty V1.5 (01.05.2025, SF-WI-GS-016 A1). Corporate Security catalogue policy V1.1 (26 April 2024 label) and report template V1.0 (17 April 2024 label), reviewed 2026-10-05; PDF bodies undated. Exact firmware assurance remains unestablished.

    IN Support Note

    After this change
    Listed on SOFAR's Indian product portfolio and the HYD 3-6K-EP page on ind.sofarsolar.com. The official SOFAR India product catalogue V1.5 (31 July 2025) names HYD 6000-EP. India has no public per-model BIS register, so registration is not independently verified here. Manufacturer listing is established; distributor inventory is not inferred. HYD 6000-ES is a different identity and is not transferred. Corporate security disclosure is published, but HYD 6000-EP firmware signing, secure boot and minimum update lifetime are not publicly established in the reviewed sources. Policy supplier-facing timelines do not create an exact-product repair guarantee. A blank update table does not prove zero vulnerabilities.

    The previous text is not reproduced here: both versions run to a full research paragraph. Both are in the JSON record linked below.
