MARSTEK VENUS E 5.12kWh. Got it in August 25 for 1050,00 EUR. It is awesome how open it is designed, I was able to activate and automate it without adding it to my local network (wifi) or using the Marstek App even once. I wrote a blog post here [1].

- Helmut10001 9mo agoThanks for the kudos. Just note, I will add an update tomorrow - I optimized the automatic, it is now working pretty well. Before it was "overshooting" and the battery fed into the grid, or went into standby too often, just to start discharging again.
