You answered my question. The back of the panels say the fuse rating should be 15a. So I’ll get four 15a fuses and one set of two 4to1 branch connectors, then I’ll be all good?
Edit:
Does it matter if I get different brands, or if they’re solid pieces vs lengthy cords, like these two different options

And are there a lot of varying factors between different brands of fuses? Or will it be safe to get the cheapest option?
