How to connect Huawei solar to RS485?

Select Huawei Solar from the list Select the "USB to RS485 converter" that you connected to the RS485A1 and RS485B1 pins of your inverter. The Slave ID should be identical to the Com address set in the RS485_1 settings. Enter the IP address and port on which the Modbus-TCP interface is available. Some pointers: The port is either 502 or 6607.

How rs485-2 port is connected to the support tracking system?

In the scenario of intelligent support tracking control, the RS485-2 port is connected to the support tracking system to collect support information. When routing the communications cable, separate it from power cables to prevent communication from being affected. Connect the shield layer to the PE point.

What is rs485-2 port used for?

Used for cascading solar inverters or connecting to devices such as the SmartLogger. Used for connecting to an RS485 slave device. In the scenario of SDongle networking or a single solar inverter, the RS485-2 port is connected to a power meter to collect information about power at the grid-tied point for grid-tied point power control.

What is a Huawei solar inverter integration?
