Now that we have plenty daylight, I'm starting to remark that my export cuts of early (a lot too early) more and more.
My export window in WW is set from 16:25 to 19:00 and the export limit is to not drop below 12%.
However the WW prediction makes it stop at 18:44 with plenty of juice left (29%).
This has been happening over the last few weeks. I tried to make the window even longer by moving the start time forward in time and leaving 19:00 as end time. I played with the battery adjustment multiplier upto 1.2 instead of 1.0 and no difference.
I have the impression that the algorithm does not take into account the amount of PV created between 16:25 and 19:00. This is not to be neglected (especially with my second NW facing area which is kicking in). It feels that the more PV is generated in that period, the earlier the algorithm cuts off the export and leaves energy in the battery that I want to export (at Octopus flux peak rates).
What's behind this ?
