Large inverters have their own transfer switch.
No inverter power does not go through the transfer switch.
Incoming power from genset and shore power goes through transfer switch, then to a branch breaker that feeds the inverter.
You could have a partially tripped circuit breaker in the 120 power distribution panel.
Is your rig a 30 or 50 ampere shore power?
Start by resetting all citcuit breakers. Turn them all off applying light pressure toward off, then turn main breaker on, if equipped, then each branch breaker one a t a time.
Ok, thanks, I have 50 amps power. I did reset all the CB. I checked the transfer box and like you say, I saw 3 sets of wires, one from shore, one from genset and one going out, so nothing from the inverter.
Now, something new, I tested the shore power post. When I test it no load, there is power, test ok for ground and earth and I can have my buffer running, but if I plug in my RV power cord, there is a very little clicking sound in the shore post box and power goes off, but the circuit breaker does not trip on the power box.
I now wonder if the transfer switch is no good or the post, and / or if the post screwed the transfer switch.
