Negative selling prices, no charging battery, only self consumption

When the dynamic selling price becomes negative, PV is only used for self consumption but not for charging the battery instead.

Why is that,? I expected the same behavior of DESS like the hours at positive selling price.

Do you have ACPV, DCPV or both?

Is that just the scheduled plan, or does it really happen like this?

Hi dognose,
I have only ACPV. It is just the scheduled plan and I didnt checkout what really happens.
I just decreased the battery costs so the energy price stays positive. In that case the normal pattern occurs.
