Some of Xantrex's smaller inverters explicitly state that they are not bonded and hence you have a floating neutral with ~60V relative to ground.
Seems to me you're confusing G-N bonding a floating neutral output with a particular wiring scheme used in some inverter designs in which the neutral is 60/60 centre bonded so the neutral and ground are intended to always always remain ~ 60 volts apart, thereby eliminating any possibility of G-N bonding the unit.
Right, I may have exceeded my knowledge when I mentioned the 60V thing.
Per my understanding, there were two basic types of inverters:
1) Bonded GN: ground and neutral are bonded within the unit, so neutral has the same potential as ground. These are most appropriate when there is no external bond of ground and neutral.
2) Floating neutral: No bond/relationship between ground and neutral (or hot). So hot and neutral are 120V apart, but ground may fall anywhere in between, if you are just plugging something in.
Perhaps the type (2) doesn't exist, and they are really "center bonded" where hot is +60V from ground and neutral is -60V from ground? Or do all three types exist?
Is there any type of inverter that would be appropriate to connect to a distribution box that has a bonded GN? Or in that scenario the bond should always be in the inverter only?
