The current direction from grid to inverter is defined as positive and 
current direction from inverter to grid is defined as negative.

CT Connection 

 

Before connecting to Grid, please install a separate AC breaker (not equipped) between CT and Grid. 

This will ensure the inverter can be safely disconnected during maintenance.

 

The connection diagram of power cable of CT is as shown in the figure below:

 

 

 
 
 

 

Please attention to the Current interchanger (CT) connection. The arrow on the CT indicates the current 

flow from grid to inverter. And lead the live line through the detection hole of CT.
