Fuse block used in reverse as combiner?
Would it be a bad idea to use a fuse block like below as a way to combine the wiring from my panels (parallel). Of course it would have to be mounted in a waterproof container but it would be handy i...

The setup you're describing is how I built my combiner box. Fuse panel that holds 6 fuses put into plastic junction box with a bus bar for the negative connections, waterproof strain reliefs for the wires coming in. I currently have 5 100 watt solar panels combining in my junction box, but recently ordered a 6th panel which I'll be installing when I get the chance.
The way solar panels work, if you short the output wiring out, the current flow doesn't increase enough to where a fuse would be likely to blow anyway. On the other hand, should power feed back through the panel for some reason the fuse could be of benefit to prevent a feed from the other panels in parallel, or the battery. I debated going without fuses, but after asking for recommendations on these forums decided to go with my initial instincts of adding them in.
