Dynamic ESS vs. Schedule export

Hi all,

I have used Dynamic ESS for a week now to understand how it operates. I see some problems in Trade mode. Is is not always prioritizing self-consumption, and therefore buy from the Grid, even if the battery is 100% full. Also in DESS trade mode the target SOC is set to min. SOC in ESS. That means in the morning the battery is empty, and I need to buy from grid before the sun is up in full swing. I therefore have to turn OFF the DESS before I go to sleep, to have enough power on the battery. And turn it ON again in the morning, to sell it at peak price.

I suggest to have a similar function like the "Schedule charging" in ESS, for "Schedule export". In that way it will be up to me to decide when to sell, regarding car-charging and other high load during the week to a specific minimum SOC as well.


My system consist of:

3 pcs MP-II 5000/48

2 pcs MPPT 250/100 + 250/85

Lynx shunt + power in/out

62kwh LFP battery.

Thank you for the tip. I'll take it and discuss it with the rest of the developers.
At the moment all of this can be done with the Node-RED implementation, though it is probably not the most easy thing to get going if you haven't used that before.

Hi @Dirk-Jan Faber (Victron Energy). Is there any change for an option to schedule a selling time to a desired SOC? I have seen many issue with DESS over the last many weeks. Peak prices here in Denmark and also any other places, seems like to be in the morning time and the evening.
