Solar Electricity: Issues with an MPP 10KW hybrid inverter

Basically what the issue is:

It takes power from the battery when the solar panels does not input any power what so ever. It should use the grid.

If i have 20w pv input it charges battery with 20w.
If I have 0w PV input it then starts using 120+watt from the batteries.

I have set the inverter to not use batteries unless its needed. Note that the inverter shows that 0amp is taken from the batteri. I think this is an software issue that should be corrected. Because if im using grid for everything it should power the inverter from the grid and not the battery. By doing that your/mine batteries will last longer!

This video is uploaded for MPP support to look into it.
