HQST's own product page for its solar branch connector pair, captured on September 23, 2026. It sells a 1 pair variant (SKU HQST-CNCT-MC4Y-G1-US, the one shown by default) and a 5 pairs variant, and prints a short specification list. It is a store page, not a datasheet: the flame class is printed without a test report or file number, and the page prints two different upper temperatures (185 F in the list, 190 F in the feature text).

Retrieved Sep 22, 2026
An Internet Archive copy of HQST's own former store page for its MC4 branch connector pair, captured on April 5, 2016, not a live page. It is read only because it prints HQST's earlier product code, HQST-MC4Y, the code an Amazon listing still prints. Its 2016 specification list differs from the current page (withstanding voltage 1000V DC(TUV), 600V(UL); temperature up to +194 F), so no figure in this manifest is read from it.
