Question Lower amp Gen breaker for the 12Kpv?

Is it possible to replace the 80 amp Gen breaker on the 12Kpv with a lower amp breaker, ideally in the 30 amp to 50 amp range? I'm using the Gen input for AC coupled solar and probably will never have more than 25 A of solar on my roof. Just trying to minimize wire gauge and conduit size on the new install. Obviously I could use a separate breaker outside of the inverter, but figured that maybe it was possible to just replace the breaker in the inverter.
