You don't need a fuse for a single panel. A solar isolator switch is a must

This.

You should not disconnect by opening up a fuse under load. Arcing is a thing. Less likely with such a small system but still potential for disaster.

I know you can switch off in software first before disconnecting but if there happens to be an emergency situation there is no time for that.
