pole of PV arrays are not permitted to be grounded.
6.7 Active power control with smart meter , CT or ripple
control signal receiver
The position of export limitation CT or Meter must between the
Inverter & Load and gird.
This series inverter has integrated export limitation functionality. To use this function,
you can connect smart meter or CT. The smart meter model is Eastron
SDM230-Modbus. The CT Model is TOP 90-S10/SP4(LEM).The primary aperture is
10mm,output cable length is 5m . The arrow on the CT must pointing towards the
