1. Flexible • Space-saving, top-hat rail mounting in household distribution thanks to compact enclosure • Flexible  use  in  applications  > 63 A thanks to external current transformers SMA ENERGY METER Universal recording of measured values for intelligent energy management A  high-performance  measurement  solution  for  intelligent  energy  management  in  PV  systems  with  SMA  devices.  The  SMA  Energy  Meter  calculates  phase-exact  and  balanced  electrical  measured  values  and  communicates  these  via  Ethernet  in  the  local  network.  In  this  way,  all  data  on  grid  feed-in  and  purchased  electricity  as  well  as  PV  generation  by  other  PV  inverters  can  be  communicated  to  SMA  systems  frequently  and  with  a  high  level  of  precision. Integrating  the  SMA  Energy  Meter  establishes,  in  all  systems,  an  ideally  coordinated  system  configuration  that  guarantees  the  highest  performance  and  stability  with  the  best  cost  savings  and  increased  self-consumption. • Suitable for universal use regardless  of  existing  energy  meter High Performance • Fast three-phase, bidirectional reading for  effective  energy  management* • Ideal  coordination  with  SMA  devices  to ensure control tasks are carried out  stably Easy to Use • Quick  plug-and-play  installation • Graphic visualization of current measured  values  in  Sunny  Portal  and  local  web  UI SMA ENERGY METER EMETER-20 *  Can  also  be  used  in  single-phase  systems.
