ESS runs very strangely!!

Hello.

I have a Victron Multiplus ll 48/3000/70-50 and a Victron SmartSolar MPPT 150V/100A. When my battery is fully charged and it needs to "Net feed-in", it all runs very strangely, the SmartSoler runs up and down in production and the Multiplus behaves strangely, it fluctuates every second, between sending power out and charge the battery, but after approx. an hour, it supplies all that the solar cells can produce to the grid.


Does anyone have an idea as to whether it is the Multiplus or my SmartSolar that has some incorrect settings now when you have to deliver power to the grid after the batteries are full?

Then that will most likely be why... Cell balancing...

Usually the bms will be sending charge and discharge singals.

The hour duration is what is set on the Charger tab....
