Breaker size on AC 300 strings

So am I right that I should use a 15 amp breaker/kill switch/surge on each string of the AC300 and same on the single string of the AC200L? This is for exterior house mounted box between panels and interior units. This will not be grid tied so the MPPTs will remain discrete. Please advise, experienced humans. Thanks!

Hello,

Do you mean that you would like to connect each load to a circuit breaker? If so, yes, that is possible.

Yes, each to its own. Thanks!
