I don't understand why you would want your generator to take over from your shore power,

So you can exercise your generator under load without having to go out and unplug from the pedestal. A bad idea, but it is done.

thank you, thats all you needed to say and it makes sence.

now here is the deeper question. of you look at any system that has both the genny and a inverter it uses a two ATS set up, or there may be a fancy three input one but I would imaging that would be very expansive. so going by the two system setup. the first is for genny or shorpower and like you said the genny would have priority but when you use the second ATS the priority in to that is the output of the first, so the inverter never has priority for a simple reason, if you are plugged in you want your batteries to not be used so they remain charged. the only time you would actualy use the inverter is if you have a power issue when plugged in or you are boon docking.

so here is a description of mine from the manufacture

"50 amp transfer switch provides
automatic power switching between two separate
120/240 volt AC input sources. It automatically
connects shore power (when available) to your
breaker panel.
When unplugged from power, it then connects your
inverter output to power your circuits. The TS-50 is
a double pole switch for 50 amp services with two
separate 120 VAC legs"

so from that I read the shorpower has the priority which is how a inverter set up should be done.
