SmartShunt and Seplos BMS

Hello!

My Question:
I have a Seplos BMS, and if the batteries are charged to 100% and the DC power should be exported to the Grid, ich have a lot of oscilation in current and Voltage going in and out of the battery.

Why is this? What can i do?

So i purchased a Smartshunt, now the problem is, even if i set my smartshunt as batterrmonitor it keeps the Mppts at "external control" and I would like my victron charging algorithm back.

But also to keep the BMS in the system for analytics.
What do i have to set?

Thank you!

@TestOr90

When a BMS is connected DVCC is the system it uses to control the system. This is how I have removed the BMS with one of my systems at home.

Just a warning though I have seen posts saying the Seplos still sends commands to the system bypassing the expected control route. But I don't know much else about it. I didn't really read the whole thread.
