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 and the en-IND 250-350KTLX0 datasheet. Apparent kVA at temperature is not the scored metric. 6KTLM-G3 is a different identity. Scored model: 350KTLX0 · checked 2026-09-03. Evidence.

Sources & references · checked 2026-09-03

Strong evidence coverage

23 of 23 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); SOFAR 250-350KTLX0 datasheet V1.4 en-IND (25 July 2025); India factory warranty V1.5 (01.05.2025, SF-WI-GS-016 A1). Corporate Product security disclosure policy (catalogue V1.1, 26 April 2024, en-INT) and vulnerability-report template (catalogue V1.0, 17 April 2024, en-INT), reviewed 5 October 2026; PDF bodies do not print revision/date.

    IN Support Note

    Current text
    Listed on SOFAR's Indian product portfolio as SOFAR 250-350KTLX0. The official SOFAR India product catalogue V1.5 (31 July 2025) and the en-IND 250-350KTLX0 datasheet V1.4 name SOFAR 350KTLX0. India has no public per-model BIS register, so registration is not independently verified here. Manufacturer listing is established; distributor inventory is not inferred. 6KTLM-G3, HYD 6000-EP and HYD 6000-ES are different identities and are not transferred. SOFAR publishes a corporate product-security disclosure policy and report template. Exact 350KTLX0 firmware signing, secure boot and minimum security-update lifetime remain unestablished. Corporate disclosure timelines are not an exact-model repair guarantee.
