The code requires neutrals to be grounded but that''s not what makes it a neutral. What makes it a neutral is that the vector sum of the voltages to the phase conductors is zero (ideally, or

It depends on the inverter and your transfer switch. Does your inverter have a common neutral and does your transfer switch switch the neutral? The answer to the latter is probably no, so it
