    7.16.4.5 makes it illegal to supply an inverter through an ELU on it's input side.


    7.16.4.5 The neutral shall not be earthed beyond any earth leakage unit.

    Only if the bond is permanent, nothing wrong with installing an ELU if a relay is used. the neutral is only earthed when in islanding mode.

    Comments are my opinion, unless regulations are attached to support the comment. This is social media, not a court room.
