It's more than just cable capacitive coupling. The converter has emi capacitors from neutral to ground and from hot to ground. Not sure, the microwave may also contain emi capacitors. Cable capacitive coupling is a minor component.
The 60V is created from a capacitor voltage divider from hot to ground and then from ground to neutral. If the capacitors are not equal in magnitude, you will see something other than 60V. Perhaps 65V on one leg and 55V on the other leg.
Placing an analog meter on one of the legs will reduce that leg's impedance, resulting in a lower measured voltage.
The point to all this is that the 60V is created by a capacitor voltage divider. It has little punch, just a little tingle when you touch it.

But that is only for non-bonded inverters, right? In my case, the inverter's neutral and ground WERE bonded, and I still got the tingle when I touched the case and the battery negative.
Huh, sometimes I look at these devices and shake my head in wonderment that they actually work - kinda tough to wrap my head around some of the theories.
Cheers!
