Hi all

I've recently had a Growatt sph5000 inverter installed with a half dozen panels and a small Growatt battery.

My main  advice I'm looking for is how to connect the inverter to my ethernet router over a wired connection rather than the wireless solution it came with. I think there is an alternative Growatt dongle for wired ethernet , though not completely sure for my model of inverter. Also, another approach,maybe more cost effective and versatile, is using an rs485/ethernet adapter. 

 

Assuming the connectivity solution involves rs485 via wave share device or some such cheapo converter card, i then thought this might open the door to home assistant, though frankly that's way behind my needs, and beyond the time I want to put into this.

So my secondary ask for is, how I'd then be able to pull CSV data from the inverter that I can graph to my own content within Excel (I am fine with importing of CSV files and dealing with data once inside Excel).

 

Hope I've explained clear enough and many thanks in advance for your comments/ suggestions
