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.

    Go on, figure the wiring out. 





    Looks to me like a simple single phase supply with a meter that has a some volt-free contacts that close when a certain tariff is in force (probably "off peak") - the proteus box at the top right contains a contactor and a 1A(?) fuse - which supplies the contactor coil and is switched (in its neutral) by the meter (eventually ending back in the cut-out N's block). So the the mid-right tails will supply the 24h CU and the left hand ones the off-peak CU. 


    I'm not sure about the T&E at the bottom and judging by the JB and expanding foam, I probably don't want to know...
