Has anyone managed to get electricity production data from an SMA solar inverter via the inverter's Ethernet port?

The inverter normally sends all data to the central SMA sunny portal via the internet and users can then log on to their individual portal account to see the plant status.

I was hoping to get direct access to the data for processing on my arduino.


Anyone has any info on this ?

A quick google search finds this pdf that seems to imply the units use a Modbus protocol.
As the system is using Ethernet then maybe you can use Wireshark to help find the answers your looking for.
Don't PM me for help as I will ignore it.

I cam across that info too.

However, only later versions of the inverters have TCP modbus. Mine doesn't.

So I was hoping to somehow use TCP/IP traffic.
