There is currently no display available for this renogy B2B. So if anyone is interested, I've made one...........
The RS485 port is Modbus RTU and Renogy gave me a datasheet showing where all the data lives
Arduino boards have serial comms built in, and just need a RS485 module adding and then a OLED display (or Bluetooth if you want to see the data on a smartphone)
I'm using an arduino leonardo (clone) at the moment, but plan to swap to a nano.
Here's mine so far;

There's no data shown yet as it's not plugged in, but it does work. I've also got pages for Alternator status, fault codes, charging status. A pushbutton changes the page.
I plan to buy a larger OLED display and fit it in the overhead console where I have a blank panel currently, progress is a bit slow at the moment as I cant get the bits.
The cost of the arduino clone hardware is ridiculously low, like about £4 for a nano, £6 for the OLED display etc.
I can see that it may also be possible to hook this up to the Victron port in future, watch this space................
