[RE-wrenches] AC Coupled with Generator

[jay]

A question about turning the AC on/off as means of primary on/off control for this AC coupling question.
Some time ago I was told that most (all?) inverters don’t like having the AC switched on/off as a means of disconnect.  
If I understand correctly this causes  the DC internal relay to have to switch under load which shortens it life. Under normal life this type of disconnecting is really quite rare ( power failures or manual )

Is this still true?
