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.

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).
