Size of AC output breaker between the AC Hot Output busbars and load panel

[uniquebobc]

What determines the amperage rating of the AC output breaker between the AC Hot Output busbars and load panel in the Magnum MS4448PAECL150 Magnum off-grid, pre-wired E-panel?  This is the breaker that is shown in upper right of the wiring diagram for this system as "30Amp Minimum Customer Installed Breaker."  In other words, how do I know what the Amp rating of this double pole breaker should be?  30A is noted as the minimum rating; what should be the maximum rating?

What determines the amperage rating of the AC output breaker between the AC Hot Output busbars and load panel in the Magnum MS4448PAECL150 Magnum off-grid, pre-wired E-panel?

The Magnum is rated to handle 30 amps of AC input and AC pass through, and requires 30 amp breakers on the AC input. 

The Magnum itself can invert battery power to make 30 amps of AC.  I don't see any reason to exceed 30 amps for the breaker on the AC output.

The Magnum manual points out that the breakers should be rated to handle 30 amps continuously. 

Of course, all AC wiring that is exposed to 30 amps must be #10 or heavier.
