30 Amp Shore Power and Bluetti

Hi:
Building a bus and I want 30 Amp shore power and a Bluetti AC300/BC300. Is there any way to wire a switch or something similar that switches from using shore power to the Bluetti based on whether the shore power cable is connected?

Basically I don't want all the 120v stuff always running through the Bluetti's inverter. If on shore power, I want the 120v appliances running directly from shore power, and have it switch to running from the Bluetti's inverter when shore power is disconected.

What you're looking for is called an automatic transfer switch- it defaults to A, falls back to B in the absence of A.

Please, use common sense when doing electrical, especially AC wiring. And I highly recommend having your work at least checked by a paid professional.

Thanks for the info. That sounds like what I need. However, I’m not sure how to connect the Bluetti output to this. I guess I can use a extension cord plugged into one AC outlet and wired into this as power “B”? This is getting a lot more complicated than the van we just finished.
