Target SOC

Q&A and troubleshooting DESS
, , ,
1

Hello,
I have have a Multi RS (1 Tracker) and a Cerbo GX. Both have the latest Firmware.

If I activate the Dynamic ESS over the VRM, I get a new menu in ther Cerbox UI (Remote Control) and it shows “Target SOC --%” but I can’t change the Target SOC there.

Is there a way to change the Target SOC? Or is there a other way like over MQTT?

Thanks Jan

That’s the target which is calculated by DESS. You can’t change this.

Just read the DESS manual :wink:

Thanks for the reply.

I have right now the DESS running for about 2 weeks and the Target SOC is still the same (–%). And my Batteries are not charging. When the Target SOC will be calculated?

Hereby my DESS settings:

“–” is normal value in some situations

But you always can have a look at the planned target SOC in VRM, for example my sytem today:

Maybe your battery costs 0,03 kr/kWh are too high?

Edit: but no, this are only 0,0026 EUR/kWh. Thats definitely not too high

I just switched the Battery coast to zero. I will see what it will do the DESS

Hereby my system:
