Are Aclara SGM1433-B smart meters 'Vector Sum' compliant?

Hi

Eventually getting round to installing solar panels (various delays from all sides) and we are being asked by installers: -
“Is your three-phase smart meter (Aclara SGM1433-B) a ‘Vector Sum Supply Meter”?

Does anyone know how we find this out as the Aclara documentation doesn’t seem to confirm one way or the other…

Thanks

    Hello all and wow what a technical question!

     

     

    I was sent this by my solar guy (its his bread and butter stuff), quite interesting and something I'd never considered with a 3 phase supply and a single phase solar system.

     

     

    Which then lead me to Aclaras SGM100-B user manuals. 

     

     

    And at the top of that document is import/export in the accuracy category.

     

    So I'm going to say yes, the Aclaras are new meters so I'd be very very surprised if they weren't compatible.

    Looks like I may have to just ‘suck it and see’…

    Thanks for all the comments
