I am looking to connect my solar inverter PV4000 to the Internet so I can register with a portal to get solar yeld information.
I have seen other posts helping with the change of domain and portal upgrades happening with tranneneegy, but I need to cross this bridge first.
I have an 9 pin serial port connection on the invertor, sat behind a RS232 blanking plate.
Does anyone know if I can use this to plug into ethernet or a WiFi module?
Thanks in advance.
