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.

    Thanks. I assume meter operators do not buy them for some reason so do not supply them. Any idea who supplied the the one you saw?




    John, I just Googled it. Alan seems to have answered the question - nobody wants to buy them!


    As I understand E7 originally, there were two meters and two CUs. The E7 part was energized during the appropriate hours and the storage heaters were filled up with cheap leccy.


    I don't think that you need that nowadays. If a smart meter will bill you half-hourly, all you need to do as a householder is to install a timer in the CU to ensure that your storage heater circuit(s) are connected only during the cheap hours.
