No I always call the customer service.

Have three strings. I need a 20 amp fuse for one of them, can I replace one of the 15 amp fuses with a 20 amp and keep the remaining fuses 15 amps?

For your case, please ensure the three strings' total voltage are close or the same to each other.

My panels have 8.9Amp.Should that be protected by 10Amp fuse?

This does not matter. 10Amp and 15 Amp are both can be used. We offered 15Amp.
