One of my transfer switches clicks on with the inverter.
Yes it does. The one on the curb side that I rewired so the inverter would operate both circuits like in my post last month. The big on about a foot away on the driver's side is the one that buzzes with shore power or the generator.

The transfer switch you are talking about switches power to A or B circuit when the switch on the kitchen wall changes position with the inverter turned on. That's why with the switch in the microwave position, the other circuit/outlets don't work and vise versa with the switch in the other position. I had to figure out how to wire it so both circuits are powered when my main inverter is on. If you decide to use a large inverter to run everything and want to make the minimum change to the coach wiring, check my post. It only takes about 5 minutes to make the wiring change in the box.

The relays in the box are 24 volts so with the inverter on, the relays and the 24 volt power supply to them use house battery power. If the inverter is turned off, there is no loss in the small transfer switch box.

Many coaches have a 2nd transfer switch with two contactor-relays to manage inverter vs shore-gen feeding front of bed inverter breaker panel, with one or the other energized, so there is no easy bypass for these if you want power to the inverter panel.

Coaches with a single transfer switch do not have to deal with extra relay coil current when there is no shore or generator.
