    ACOPOWER's own US store page for the 60A Midas MPPT controller, captured September 28, 2026. Its Specifications tab prints one comparison table covering the 30A, 40A, 50A and 60A Midas MPPT models side by side. Cited for the Workmanship Warranty row, as a second source where it agrees with a manual, and for figures that differ from the manuals, which are kept as alternatives with a warning. It links a 30A/40A manual and a 50A/60A manual, both read in full; the manuals are the primary source. No certification mark is printed on the page.
