Sungrow String and ESS Implementation

[Sn0w3y]

Based on the Implementation of @clehne in opernikus-common fork.
I adapted it to use ElectricityMeter

Thanks to them

We have too many open PRs with similar issues. I suggest we work on #2566 first (see the discussions on Coding Guidelines there). Afterwards we can re-open these PRs one at a time. Thanks!

Any news on this?
@tsicking would I be forced to merge the PR myself for my first experience with OpenEMS or is there any schedule planned to accept this PR?

[Sn0w3y]

Closed as i guess it is a WIP

We are still working on it and we are testing it thoroughly. I will update this PR when we are done. You can merge it yourself and can use it as a starting point.

@tsicking Any update on the sungrow inverter and ESS support for openEMS ? I can't find this anywhere.

[sfeilmeier]

@nishad-apollo: Can you actually test the implementation with hardware? I could then re-open this PR for you and clean it up (e.g. moving everything to one common io.openems.edge.sungrow bundle)

Sure, I want to test the bundle but not able to find in the develop branch, could you let me know then I could test it once. Is sungrow ESS and inverter still WIP or already released ?

[sfeilmeier]

It's not officially released yet.
The latest "close to official" branch is here: https://github.com/Sn0w3y/openems/tree/Sungrow-ESS-and-Sungrow-PV-Inverter
If you are able to test it, we should be able to make it official relatively quickly. When are you planning to test it?

[nishad-apollo]

Got it..

I got redirected to https://github.com/opernikus-common/openems from the comment section. Is this correct too ? Looks like forked from this repo. Or should i consider this specifically ? https://github.com/Sn0w3y/openems/tree/Sungrow-ESS-and-Sungrow-PV-Inverter

Test - Yes, Will start testing Next month, trying to figure the build now. Will update here, It will be great to make this official.
