@EG4_Jarrett did you ever get a chance to dig into this? I'd really like to be able to query the inverter directly using RS485, in addition to using the wifi dongle if possible. The only RS485 pins I've found that are referenced explicitly are pins 1/2 in the BMS port, but those don't seem to respond to input register query commands. I expect those pins are setup as a modbus master in order to query BMS devices and aren't going to act as a modbus slave.Sorry, I didn't see the tag in my notifications or I would have responded sooner.
I haven't played around with any of the 3rd party stuff yet, so I don't know right off the top of my head, but I will do some research and see what I can find out!
Can you clarify the language in the current 6000XP manual regarding what exactly is meant by "Meters 485B and 485A can be used when a meter is not connected"?? I'm not sure what "meters" they're referring to, but it's not the wifi dongle since apparently the wifi dongle shares a connection with the INV485 port, whatever THAT is
Cheers,
