Warranty coverage: 5-year term
Coverage includes
Parts & labour · term longer than 0 of 95 scored inverters
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.

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 an independent guarantee that a claim is correct.
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
- Current text
- 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.
