Description of the floating neutral phenomenon when some inverters go into autonomous mode.

**** Beware, electricity is dangerous because it is invisible, silent and odorless.

The consequences can be fatal if you do not master this subject ****

The neutral is no longer grounded, so it is in floating mode. 110V on the blue and 120V on the phase.
This would not be a problem if it did not put your electrical box out of play and especially the differentials that can no longer detect a leakage current and therefore break.
I do not understand how these inverters can be sold in France ?
