1.
The RS485 port between the ZeverCom/ZeverCom WiFi and
the inverter (Item C in Fig. 5-1) uses the RJ45 socket. Please
make sure to use the correct port.

The maximum communication distance of the whole RS485
bus is 1000m. Communication quality beyond this length is
not guaranteed and can also be influenced by the quality of
the RS485 cable.
