    Good evening, @BPLightlog 

    Thank you for getting back to me, Very interested in what you say about about the site you are speccing. I would be interested in which model of AMR your client has.
     

     

    I will have to search back (edit - it’s an Elster A1140) but it looks like this 

     

    We also have a polyphase AMR meter provided by Western Power ( Now part of National grid who are our DNO.) same situation, that SSE could not supply at the time. From what I can glean, though the meter might be capable of net metering the supplier also has to be! Is this your understanding?

    As far as I’m aware, it’s down to the configuration of the meter .. the manufacturer should be able to set that up. Once that’s in place, I don’t see why the supplier shouldn’t take it as the meter has done the hard part. Unless some suppliers use a different calculation from a ‘non’ net metered unit. 

    We were recently migrated to Ovo from SSE and have run into a problem that Ovo do not recognise this meter as being even semi “smart” and as they have decided to not have a system for remote reading of these units, Which SSE did in part( Export),  we are  running into communications issues.  Not Prying, will your client be claiming fits? if so I guess they will be under SEG tarriffs, so should be ok. If they will be 0 threshold for export due to battery storage then I guess export issue will not arise unless they exceed battery capacity. 

     

    There are tariffs now that will take battery export so it’s worth checking. On this one, they are planning to add batteries later and are not sure about SEG as much of the power generated will be used on site. 


    ​​​​

    If I manage to take this forward will you be interested in the detail?

    regards C.

        

    Always interested as Jeffus mentions, it often helps others as we build further knowledge.

      My knowledge of FIT is limited @Colin Wheeler 

      Out of curiosity, what year do your FIT payments end?
