Hmmm, on our apex, the receptacle behind the passenger seat is on the inverter, as we came off that one, and added one under the new cabinet we had added along that wall (mid-door model w/big window). I keep a weather alert radio plugged in and on all the time in that plug-in. The kitchen plug, the MW, the one on the back kitchen wall, and the bathroom sink area are all on the inverter as well. I don't use the MW unless I am plugged in to shore power or the genset is running, bad for the transformer in the MW, does not get the right starting current, there is a lag. Have only tripped the inverter off line one time, and that is when the microwave receptacle failed and shorted out, once I had a residential type installed (required a new half-depth box so it would screw in) have never had a issue. Should learn how to fix all the other ones since then they all would be better quality.
