Size you nain semi conductor DC fuses for your largest single use. If not the AC, then microwave, toaster, coffee maker, hair dryer etc.Using a semi conductor DC fuse means it clears based on current rise time, not current alone. That's why they are so expensive. Think of them as safety devices. I have 150 amp Eaton Amptrap fuses (2 because I doubled up my cables and havev2 main disconnects as well) which can handle the AC, my single largest load.
Stay safe!
