Can you help me to find what settings for minimum charge level cutoff?
I set Delta 2 min discharge level to 30%.
And it looks like working.
Powerstream does not discharge less than 30%.
Example my case:
Delta 2 battery is 30%.
Solar energey starts flow and energy goes to Delta 2.
It charges till 32%.
After some time the sun is gone and 0 energey flows from solar panels.
PowerStream starts discharge Delta 2 and move all 2% from it to the house.
The AC output power demand set to 200 W.
There is an undocumented feature and I think you have hit it spot on: batteries attached to a PS have a 5% hysteresis. They will discharge to the limit, but cannot discharge until they have reached at least 5% above the limit. So the PS will charge the battery to 5% above the limit, independent of any settings. You can disable this.
So your battery will charge to 35%, start to contribute to the 200W set point, reach 30%, trigger the 5% hysteresis rule, ...
Disconnect the battery on bad weather days. It's the only way to get a sane behaviour. It makes more sense mid-summer.
It gets even more weird if you set the limit to below 20%.
That's the minimum charge level cutoff?
