5. COMMUNICATIONS
5.1 Data communication with RS232
Fig. 10 RS232 serial port
Open the cover of RS232 serial port, connect solar Inverter and computer by
RS232 cable. By the way, the communication distance should be below 10m.
If your computer doesn't have any RS232 port, only has USB ports, please buy a
RS232-USB converter for the communication in the local market.
5.2 Data c ommunication with RS485 (optional)
5.2.1 RS485 Serial Port
The RS485 is used for several inverters’ communication. Ethernet cable is applied
to connect each inverter herein. Only three cables in ethernet cable are applied:
two signal ones and one for ground connection.
