Overview › RS485


RS485 port

The USB port on the inverter can not be used for monitoring. You need to connect it via an RS485 cable by screwing the RS485A and RS485B wire into the communication port. Each inverter will require it's own USB cable.

You can also explore alternative RS485 adapters that might be available locally in your country.
