Combiner box rating check

Defaults are invented: a module with Isc 9.0 A, a 810 V cold string and a 15 A string fuse. The factor 1.25 is an assumption. Use 1.5625 (1.25 x 1.25) only if the manufacturer's rating includes a second 1.25, and ask the manufacturer which basis it uses. Box presets are copied from the datasheets named on the page. Replace every value with your own datasheets.

Design aid only. It compares your numbers with the box ratings. It does not size fuses or conductors, and the box must also be listed and accepted by your AHJ. For the recombiner preset, enter the strings behind each input in "Strings per input".
