Overview › RS485

RS485 port

A purpose built USB RS485 cable can be plugged into the RS485 port of the inverter. This is an RS485 cable with a specific RJ45 pinout that can be purchased in our online store.

If you buy any random USB RS485 RJ45 cable on Amazon, Ebay, Takealot, etc. which doesn't specifically state that it supports the inverter, it will most likely not work. Note an RS485 cable that says it supports the Deye inverter should work as it uses the same pinout.
