You have more than two panels in parallel? What are the panel ratings? link?
If you are using MC4 why even have a combiner box? MC4 combiner is fine and you can get #8 MC4 down to the controller if you need it.
Otherwise yes any 12v fuse is fine.
I have a couple reasons for a combiner box. First, it came with a Zamp combiner box that was rather butchered up when the dealer installed the existing Solar. There was MC-4 cable wrapped round and round in circles on the roof and in the attic. When I yank the the butchered Zamp box, something needs to go back in it's place and since I'm adding a third panel, that something might as well be a combiner box to tidy up the roof wiring. And I'm not really using any MC-4 Connections. Was going to use an MC-4 Fuse holder but they don't fit in the combiner box and I'm trying to keep all connections in the box.
