Hi
Welcome to the forum.
I hope you can supply some more info, because currently this does not look sensible to me.
Not only are you using a fuse as as if it's a terminal block, you are showing it in a circuit as if it protects the solar panels.
Solar panels can be short-circuited with no harm. It is commonly done, and no fuses are needed.
Bear in mind that fuses (any circuit protection for that matter) is sized and located so that it will protect the wires from melting their insulation.
Always size the wires to handle the current in the wires to run the load, and you size the supply to always be adequate for the load.
The size of wires that can handle 125 Amperes continuously is the size of welding cable.
On a more subtle level, I bet the wires from each bank of panels is sized for only 1/2 of the total current (62 Amps) meaning that the wires of either bank could melt before the fuse ever popped.
I think we need to know more about the load, or the battery being charged, to give you advice suitable to your needs.
