Interpreting DESS

Hi all

Would greatly appreciate some help interpreting numbers.

System as follows:

15Kw battery bank 24 x 2V 660Ah BAE spiral wound gel cells.

16Kw PV through 3 x 250/100 Smart Solar MPPT.

Cerbo GX

500amp Smart Shunt

Quattro-ll 48/5000/70-50/50
ET340 energy meter (single phase system)

DESS is set to sell excess to the grid, buy and sell prices are not variable

How do I read the below, I get the below screen (or similar numbers for about 8 seconds, then the lower screenshot for around 12 seconds, then repeat.

Another even better example where the numbers just don’t add up, 2800W from Solar and PV, 8251W from grid = 11Kw, where does the 16,57 come from
