6.2.2. RS-485/422 Communication                                                                                             

RS-485/422 is generally for multi inverters’ communication.  It can communicate with and up to 32 
inverters  could  communicate  at  the  same  time,  but  wire  length  should  be  ≤  1200  m.  Connect  the 
system as blow (Figure 6-2), user can easily monitoring the PV power station.
