DC Connection 

4.3.1  PV mode configuration 

The two PV inputs can be configured in independent mode or parallel mode. Refer 
to the user manual for an appropriate mode selection. 

PV configuration mode can be performed by a switch on the configuration circuit 
board. 

 

y

 

For independence mode: turn the switch ON. 

y

 

For parallel mode: turn the switch OFF. 

When selecting parallel PV configuration mode, you should connect DC1+ to DC2+ 
and DC1- to DC2- on the DC connection circuit board by inserting jumper cables of 
cross-section not less than 6mm

2

 (10 AWG) as the following diagram shown.
