I noticed a behaviour in DESS that in my opinion can be improved.
Below image shows DESS want to feed in to grid but also charge the battery in the current hour.
I noticed it actually feeds in to grid in the first part of the hour (unfortunately i lost the screenshot). That is ok for the PV inverter as it is AC, but the DC energy from the PV charger must be converted to AC by the multiplus, hence we deal with conversion losses.
The latter part of the hour the battery is chargeD from both PV inverter and PV charger. So in this case we suffer from AC->DC conversion losses from the PV inverter.
It would be more beneficial when the PV charger energy goes into the battery for the whole hour and the PV inverter energy goes to grid at the same time (as long the targets are not met).
