thank you ! for several years, I was missing 1 of the 2 circuits from the inverter. There are two receptacles on the back of the inverter, both  were producing power, From there two portable cords go into the great unknown in this wall. I never heard the relay work, with the noise from the transfer switch being louder. I don't understand why it was behind a false wall in the closet, but I am pretty sure I will find 1 leg of this relay is non op ,,,
