No nothing out of the ordinary was plugged in (heater or anything).
There is a small reset button on the bottom of the inverter, but that is not tripped.
The only thing that was maybe a bit unusually now that I am thinking about it is I had some family staying in the RV while it was plugged into my house (shore power) and my house breaker kicked off when both RV air conditioners were turned on at the same time. I reset the breaker on the house and everything was fine.
Don't know if this could have done anything to the inverter and would imagine it couldn't.
