Just to close this out, after a bunch of research into specific inverters my conclusion is that an automatic transfer switch is not a good idea. What I will end up doing is just having a backfeed circuit breaker to bypass the inverter at 150A. My service panel also will have several extra provisions that would allow me to shift loads to non backed-up panels if necessary.

Ultimately, I think @Dave21's experience gave me the biggest push; the system really needs to be designed to operate at the worst-case scenario. I'll set my system up so that I can add a isolation contactor and a second inverter in the future if needed.
