2.3.2 Steps of connection
Both ends of the connecting wire are terminated with RJ45 network cable connectors all the
line sequences are T568B.
A. Single inverter connection
1) Disconnect the power supply of the inverter
2) Insert the network cable into any one RJ45 port on any one inverter
3) Let the other network cable connect to the network interface of PV data collector
WIFIKIT
4) Connect the power supply adapter to the data collector, then insert into the
socket
B. Multiple inverter connection
1) Disconnect the power supply of the inverter
2) Insert the network cable into any one RJ45 port on any one inverter
3) Insert the other network cable into any one RJ45 port on a second inverter
4) Make the needed monitoring inverters in series in the same way
