Sunsynk Ecco 3.6kWh hybrid inverter rs485 port #151

Closed chsims1 closed 1 year ago

Sorry for very newbie question here. I have tried an rs485 connection (as recommended in the documentation) from a Raspberry Pi to the port marked RS485 on the inverter, but I do not get any data out from the connection. I vaguely remember reading somewhere else, that this port does not work on this particular hardware, but that someone was successful in using the BMS CAN port.

My inverter is up in the loft, so not readily accessible, but can any one confirm or otherwise which ports on this inverter are appropriate to use?

Cheers.

Yep I had, but they have been greatly updated since last time I looked. Looks like I have the combined RS485/CAN port. Thank you very much for your help.
