battery charging priorities in DESS

Is there in Dynamic ESS ever has a plan to add a function "charge first battery, then the remaining power to the grid"?

It often happened that the remaining PV energy is charged to the grid and bought back in the following hours, which is a rather pointless activity...

today's example:

12:00 - 12:59 5,5kW to grid

13:00 - 13:50 0,5kW from grid

I have to same issue.

My system contains of an AC and DC PV. The target DESS SOC remains low eventhough PV is exportet to the grid. Why not fully charge the battery with priority with the DC charger during the day, instead at the very late afternoon? It would be more efficient anyhow.

DESS is now in production and this is an old beta topic. Rather post in Q&A and ideally in the dedicated DESS topic that is a sticky on that section.
