No charging with DESS

[TobiasFrank]

I tryed a lot to solve this issue and i think there is a misconfiguration on my side, but i cant catch it.

i dont have a pv generator so its all ac charge and discharge.
this night i had cheep times over about 6 hours but the battery did not charge. after i rised the soc by 2 % it charged only the 2 % and stoped after. I cannot see any charging schedule on dess so my battery is stuck at aprox 13%.

any thoughts on that?

also i think the formular is not working because when i rise by 2 cents the graph did not update to a 2 cent higher price…

very wierd…

Ok I think i understand why it happened like that. Its the algorithm and calculating costs of buy energy, conversion loss two times (AC-DC-AC), and battery cost per charge the forecast of buying energy and using that stored energy plus all the costs compared to the price of energy at a specific time. And when all that is lower than the price at a specific time, only then it will charge the batteries from grid.
