  PV Array Wiring Methods 

1.  Standard  mode:  Two  strings  that  each  of  them  in 

different  numbers  of  PV  array  can  be  configured 

independently, as shown in Figure 7. 

 

Figure 7 

2.  Parallel Mode: A single-string PV array is connected to 

String  A  and  String  B.  It  should  be  configured  in  the 

Setup Mode, as shown in Figure 8. (See Section 3.4 for 

details of the Setup Mode.)
