Not sure this is a bug but no-one responded to a post I made about this a few month back. I have the same "problem" but it does recover within a few mins. In my case, I have 2 trackers and both go down to zero for a few minutes when the charge voltage is at its peak (52,4 in my case for Pylontech). I read somewhere this is normal behaviour as the charger needs to switch to a different method to ensure the max power point can be kept as the multi is slow and the battery still needs to buffer shading impact whilst being at 100% charge.
Definitely good to raise it here. Hopefully someone can either fix the few mins of delay or explain it a lot better than I can :-)

What happened?
My system runs very well without the dynamic ESS. I have decided to use Tibber with variable prices from 01.08. and wanted to test the dynamic ess in this context. I have set up everything and activated the dynamic ESS. Everything went well up to the point where the battery was full. Then the power of the Mppt was regulated to 0 W. When I switched the dynamic ESS off again, the power went back up. WHERE is the error?
When did it happen?
Whenever the battery is full and there is more solar energy available than required.
