6.5 Communication Connection
6.5.1 Communication Overview
The inverter operation information can be transferred via its integrated RS485
interface to a PC with monitoring software (such as SolarInfo Insight), or to data
logging device (such as SolarInfo Logger).
RS485 is the standard communication choice for inverter.
The communication terminals (RS485) are located at the bottom of the inverter.
And there are two optional connection terminals on the configuration circuit
board: RS485 A/B terminal blocks and RJ45 plug in terminals.
If a 120Ω terminating resistor is to be connected between the communication
cable A and B, connect the terminal resistance by using the dip switch.

Before communication connection, prepare communication cable and RJ45
plug.
