Searching for similar connector on the internet, only one I could find so far was on ebay: https://www.ebay.co.uk/itm/155648938095, as well as a RS-485 to USB cable: https://www.ebay.com.au/itm/Communication-Cable-Connector-CC-USB-RS485-150U-4LLT-For-Epever-SolarController/372473784094 There is also a converter: https://watts247.com/product/cable-rs485-solar-assistant-remote-monitoring-nhx-adaptor-use-with-solar-rs485-to-usb-cable/ (overseas site, but it says it is a adaptor cable for Solar Assistant). Alternatively, DIY Solar Power Forum has some MacGyver solutions in this thread: https://diysolarforum.com/threads/connecting-solar-assistant-to-eg4-megarevo-8kw.67758/

I forgot to add that I had enquired from SolarAssistant about this, and they concurred that running ethernet cable next to power cables would be a bad idea. The support agent also stated

I am busy finalising planning for the installation of my first solar system, and intend to make use of SolarAssistant. For several reasons (which we do not need to get into) I would prefer to run CAT6 ethernet cable from the SA Raspberry Pi to my router, and I have seen several people on this forum suggest it (e.g. in this thread). Originally I had planned to route the CAT6 into the ceiling through the same trunking as the cables to/from the inverter, however over the weekend I came across a blog post and accompanying YouTube video saying that this is a very bad idea, since the electrical cables generate an electrical field (EMI/EFI), which can cause data loss or corruption, as well as inducing heat in the network cable (possible fire risk). I would therefore like to hear from anyone who has actual experience using ethernet cable in this way, and what precautions you took to mitigate or eliminate these issues.
