Yes, absolutely. With single phase loads, neutral is active and I must point
out again, do not connect neutral to the inverter chassis. The inverter
internally will connect safety earth to the inverter chassis. Do not tie
multple inverters together unless they can be synchronized and they must be
designed to do that. If you intend to power a common load with two
inverters, they cannot do this together. It is one or the other.

Another rule is that safety earth should never be switched. So, a source

electrical connections are consumers. Consumers use distributer
connections
for phase, neutral and safety earth. Consumers are not allowed to create
their own earth.

In the case of multiple sources and a common load, there can only be one
earth reference and neutral of each source is connected to that singular
earth reference at each energy source. Ideally, all sources should be as
close as possible to the earth reference.

So, it would seem to follow inescapably that the neutrals must be
switched where there are two alternative sources of power, even if
they are isolated from each other, yes?
