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.

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
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.

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.

- Three-phase 800 V, 50 Hz or 60 Hz. The en-IND datasheet lists EN/IEC 62109-1/2, EN/IEC 61000, IEC 62116, IEC 61727, IEC 61683, IEC 60068-2-1/2/14/30, EN 50549, EN 50530, VDE-AR-N 4110/4120, NTS 631, UNE 217002 and IEC 62910. It does not name an India grid code. DISCOM and site settings remain installation-specific.

IN Support Note
- After this change
- 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.
