Since you don't name the inverter OEM, I'm just guessing, but.....the ground to neutral bond thing can indeed fry what I call "truck top" AKA "portable" inverters. The puzzling thing in my experience is it can take 6 months......1 month.....1 week......1 second for the failure. Or it might work fine (but not be to code).
My rule....to connect to a standard AC load panel (no matter how small) the inverter has to have actual hard-wired AC Out terminals...hot, neutral and ground. If the only way to connect it to the house AC system is a 120V AC extension cord with the female end chopped off and hard wired to the load panel, you are asking for trouble and have left NEC far behind. I got well-zapped by one these in the past....
