Connecting Renogy Inverter / Charger to Cerbo-GX

I know, get a Multiplus. Sorry, this is for a small-ish sailboat, and the Multiplus is a bit too large to fit, and twice the weight of the equivalent Renogy 3.5kw inverter / charger. So I got the Renogy. But the rest of the system will be Victron, so Cerbo-GX (or Venus OS on Raspberry Pi), DC-DC chargers, SmartShunts, etc. I just need help in getting the Cerbo to talk to the Renogy. Searching the various forums hasn’t turned up anything particularly helpful. My questions:

  1. I expect the communication would be via the Renogy’s RS-485 port (yes?), so will need an RS-485 to USB dongle. Is there a particular dongle (e.g. USB chip) that I need to use, or are they “all” more or less equivalent?
  2. I believe I will also need to add a driver to the Cerbo to talk to the Renogy. Which one do I need, and where to get it?

Thanks!

There is no communication, since the Cerbo is made to communicate with victron devices. Yes it also communicates with other stuff, but especially the inverters and Multiplus use the VE.Bus interface, which is proprietary.

You may be able to cobble something together by using nodered. Read the information that comes from the RS485 and send that to a virtual device. But thats far away from plug and play
