Port	Pin	Definition	Remark
RS-485-1	1	RS485A IN+	Imerter RS485 networking or connect

Push the seal body into the seal ring, then push the claw Clockwise tighten the nut with torque 8+/-2 N·m
Keep the buttons on both sides pressed and then connect them to the communication port on the inverter. You will hear “Click” if it is correctly connected

Monitoring connection

SolaXcloud is a mobile phone application that can communicate with the inverter via WiFi/LAN/4G. It can realize alarm queries, parameter conﬁguration, daily maintenance, and other functions. This is a convenient maintenance platform.
Plug Dongle into the “USB” port at the bottom of the inverter. After the DC side or AC side is powered on, the APP and inverter can be connected. Please refer to the corresponding manual for details.
