4.6.  Using the Grid Port 

 

It looks a little complex, but it is quite simple. A few things to keep in mind:  

You  may  choose  to  connect  the  generator  to  the  grid  port.  This  is  okay  from  my 
personal experience, but not all generators are compatible, and the system will simply 
not work. 

Remember that if you are connecting the generator to the Grid port, you must fit a CT 
coil  and  set  the  Zero  Export  feature  to  around  150W.  This  will  prevent  the  inverter 
exporting power back to the generator. 

 

 

 
 

 

 
 
 
 
 
 

 

 
If using Grid port, remember you will need to make all settings to charge 
from Grid and Grid Signal rather than generator.
