Goodwe DT Series User Manual

Note:
The requirement of RS485 communication cable: standard RS485 cable.
3. The choice of 120 ohm termination resistor dip switch (DT series only).
• If there is single DT series inverter, RS485 connection cable with waterproof terminal can
realize the connection
• For single inverter communication, choose one among the two terminals. Please use a
waterproof cover to cover the port which is not used.
• 120 ohms termination resistor is controlled by dip switch. "ON" means connected, and "OFF"
means disconnected.
• For single inverter communication, put on the dip switch near the terminal (default is OFF).
Then shielding layer of communication cable is single point grounding.
• If there are several PV inverters, their connection can be realized by RS485 communication
cables in a daisy chain connection.
• For the last inverter in the daisy chain, put on the dip switch near the terminal (default is OFF).
Then shielding layer of communication cable is single point groundin.

4. RS485 communication method
• DT series inverter can be connected with EzLogger pro separately for data acquisition and
monitoring.
• The connection method of single DT inverters, EzLogger pro and PC terminal.
