First question is do you have a salesman switch? Second question is do you know where it is? Usually it's near the front door, but it depends on the mfg. This switch is designed as a convenience switch to turn off A/C power quickly without having to turn off the disconnect switch in the basement. Check to see if yours in on. Recheck the breaker on your inverter. On mine it's a really small push button and easy to miss. Yours may be different. Recheck all your wiring. It's easy to overlook the simplest things especially wiring. Be sure to let us know if you are successful in tracking down the gremlin...Dennis
