Connect SolarAssistant to the RS485 port

To connect SolarAssistant to the RS485 port, you need a specialized USB RS485 cable with the RJ45 pinout shown below. This cable plugs into the RS485 monitoring port inside your inverter and connects to your SolarAssistant USB port.

Deye RS485 cable

Important: Generic USB RS485 cables from Amazon, eBay, Takealot, or other retailers will not work unless they specifically list your inverter or the pinout shown above. The pin configuration is non-standard and incompatible with most off-the-shelf RS485 cables.

Deye RS485 port

The RS485 monitoring port is located inside the inverter. Open your inverter to access it. The port labeling can be confusing and varies between models, so refer to the image below to identify the correct port on your specific inverter.

Once you've located the RS485 port, plug the RJ45 connector into the port and connect the USB end to your SolarAssistant device.

Note: On some models, the BMS port can be used for both SolarAssistant monitoring and battery CAN communication at the same time. See the 2-in-1 BMS port for more information.
