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?

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.
