Huawei's own two-page datasheet for the MERC-1100W-P and MERC-1300W-P, linked as "Datasheet" from the Download & Support page of the model pair on solar.huawei.com and captured on October 14, 2026. Its Technical Specification table on PDF page 2 has a MERC-1100W-P column and a MERC-1300W-P column; the rated and maximum input and output DC power rows have a cell per model, and every other row is one cell spanning both columns (read from the rendered page and confirmed by the web page's own markup). The datasheet prints no version number, date, market or region. Manufacturer claims, not independent tests.

Huawei's own global English specifications page for the MERC-1100W-P and MERC-1300W-P, at solar.huawei.com, captured on October 14, 2026; the content is whatever the address served on that date. Its table has a column per model; the rated and maximum input and output DC power rows have a value per model, and every other value is one cell marked in the page's markup as shared by both. Only the Technical Specification table and its footnotes are read; the page's PV System Design table and its marketing text are not used. The page prints no market or region and carries no revision date. Manufacturer claims, not independent tests.
