EDIT - Sorted itself out....not sure how.
I am definitely a beginner here.
I have a KH9.9 and have wired up a Waveshare Modbus adapter using POE.
I have the Modbus connected to a POE switch which is then connected to my Eero router.
When connected using POE, the power light on the WS is bright red. If I disconnect the ethernet cable and power the WS with a usb cable connected to a power socket, the power light is less bright.
With POE connected, I get a very faint yellow light on LINK. THe device is visible on Vircom.
My issue seems to be arising when I try to update the BIN file. I get a "flash wirte" error.
Any thoughts?
I've checked the wiring and pins and all seems fine.
I don't have the PoE version myself but I know a lot of people that use it sucessfully.
The Waveshare has a wide voltage tolerance but when connected via USB it is at it's lowest range (it can be as low as 3.3V but more typically ~5V), whereas PoE is closer to 48V and so I would definitely leave it connected this way.
If it's showing in Vircom that is a good start, I know a few users have had to do factory resets when trying to flash firmware, from memory you have to add a link across a couple of pins to do that.
From my own experience of using the non PoE version, I found that the ethernet port isn't particularly fast (10-100Mb) and so I set it to a fixed speed rather than auto in the switch.

Hi. I've got RS485 to PoE ETH(B), also, and KH9 inverter. i can see in the socket marked Meter/CT/RS485 that there are two cables going in (I assume that's the meter cable and the CT cable) and a small black plug, that, again, i assume is for a cable for the RS485 connection.
I just have some of questions;
1) am i correct in my assumptions?
2) can you make the RS485 connection without removing the main plug?
3) do you find any issues if you have an EV charger and also do you have any issues if you are on an intelligent charging tariff (I'm of EDF Go Electric with smart charging bolt on)
Thank you
