FOXESS CO., LTD.'s own two-page datasheet (PDF) on us.fox-ess.com, linked from the Downloads > Datasheets page of us.fox-ess.com, captured on October 27, 2026. The page 2 table is read from the rendered page: the PDF text layer prints the row labels and the column values in separate runs, so each cited value is quoted as it appears in the text layer and its row and column were confirmed on the rendered page. Page 1 prints the subtitle "HIGH VOLTAGE STORAGE BATTERY" under the product name, which the description and the table contradict (it is a smart energy management system). Manufacturer document, not an independent test.
