Make DESS aware that PV can be turned off when prices are negative

How can I make DESS aware that my PV will turn off during negative price hours?

For example recently in the Netherlands, DESS made a schedule that only charged the battery as fast as the predicted PV output could handle. However, solar is almost free but negative pricers are more financially interesting. In my option, it should have made a schedule that grid charged at max capacity during peak negative prices.

Also, I’m slightly concerned that turning off PV is going to have an affect on PV prediction as that used historical data and isn’t aware that I turned it off.
