smart meters: questions to ask?

DavidMartin
My electronics does not quite extend to domestic power systems so would appreciate advice: 


We have a 4kW PV installation (which works well), but I understand some smart meters are incompatible with PV installations.  Partly for that reason I have prevented installation, so far.

I also understand that smart meter standards are still settling and not all meters being installed are guaranteed to work for the forseeable future, through changes in suppliers, etc.

There also seem to be issues around safely and future maintenance of some smart meter systems.


So ... can the team suggest questions I should ask to reduce the risk of a 'bad' smart meter installation ?


Thanks.

    A switched neutral makes the contactor able to be run off its own live supply, which is the desirable simplification.

    Some countries do give volt free contacts, and then it is up to the end user to arrange their own contactor.


    That style of meter does support that mode of wiring  providing both sides of the relay contact on some smaller terminals under the cover - hence the extra neutral tail to the head.
