6.6 Grounding the inverter
The inverter must be connected to the AC grounding conductor of the power distribution
grid via the ground terminal (PE) .
WARNING
Because of the transformerless design, the DC positive pole and DC
negative pole of PV arrays are not permitted to be grounded.
6.7 Active power control with smart meter , CT or ripple control
signal receiver
Information
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 inverter.
Step 2 Insert the H type tool and pull it out from the socket.
