Question on configuration

[adradr]

First of all thanks for this great plugin!
I configured and mostly it works great however I do not understand why the battery discharges way above my grid import figures.

My config is the following:
I have a PV system and in my country (Hungary) we can uae the grid as a virtual battery on an annual basis so on each new year it resets, but I can import as much as exported within a year. That is why I though it would be a great plugin to simulate this behavior and show me how much I am importing as paid energy or using as an exported surplus.

I have configured the virtual battery for 20k kWh as that is around my annual production. Set charge and dischare at 100 kW and efficiency at 1.0. As import and export sensors I am using my utility meter sensors. Furthermore my virtual battery is configured for Default mode.

The problemw as this chart shows is that during the afternoon the virtual battery discharges way more than my actual consumption based on the utility meter import data. Both the battery and my grid stats are showing the same 44.9kWh sum.

What am I configuring wrong?
