Freddy, No, 110vac will never be fed INTO the inverter, if you hook up the relay correctly. Double-check the relay diagram above.
1) The BLUE
arrows tell the rest of the story. What gets hooked up to the center pin, is the inverter's old 110vac OUTLET that has been cut out of the inverter. THE OUTLET can be connected to either 110vac from Utility (Wall outlet), or from inverter's 110vac output. There is no way the inverter output can be hooked up to wall outlet. Thats a no-no.....
