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.

    Smart Meters can cope with reverse power, and this could have been used, However, the British government in its wisdom decided that the householder would be paid a unit rate even for electricity used by themselves, hence two meters, on registering import only from the public supply, and one registering the renewable generation. This, and the fact that the renewable and standard supplies can come from different companies has just added to the mayhem. The meter for the public supply must be set so it does not count reverse power, and also need to have its anti-tamper flag ignored by the supplier. This is one of the reasons you must.inform your supplier when you have renewable generation installed. 


    The easiest option would have been to record import and export power from the public network, which can easily be done on a single device, both with conventional and smart metering.
