SMA Modbus EMS - work in progress #222

Open hopfi2k opened 3 years ago

hopfi2k commented 3 years ago

I have started working on an EMS module for SMA Inverters using the Modbus TCP protocol. Are there people out here that are using SMA Inverters? If you do, please comment here and let me know if you are willing to test things.

According to the SMA documentation, you can active Modbus support in your SMA inverter with the following steps: 1. Establish a connection to the user interface (see the inverter manual). 2. Log into the user interface as an Installer. 3. Select the Device Parameters tab. 4. Select [Edit parameters]. 5. Select the parameter group External Communication. 6. To activate the TCP server, make the following settings in the group Modbus > TCP Server: • In the drop-down list Activated, select the entry Yes. • If necessary, change the port in the field Port (default setting: 502). 7. To activate the UDP server, make the following settings in the group Modbus > UDP Server: • In the drop-down list Activated, select the entry Yes. • If necessary, change the port in the field Port (default setting: 502). 8. Select [Save all].

Thanks for your support!

Bit late to the party, but if you're working on this I currently I use https://github.com/meltaxa/solariot for modbus TCP (sungrow Sh5-k). I'm sending to dweet, then TWCManger reads from there, but would love a contained system
