Battery discharge is greater than charge

I've had my system installed for almost a year now. It all works fine but one thing seems odd. When I look at the Battery Analysis Graph in the FoxESS App for last year, nearly all months show a larger discharge amount than the charge. The flow directions are correct so I don't understand how this can be happing.

Hello Mike,
Datamonkey posted similar yesterday about numbers not adding up.

If you see my reply in the 2nd post, my SoC was 56% from a discharge (from 100%) and after a few hours it increased to 71%.
My system is just over a year old also, it reports 2414.00 kWh battery total charge, and 2165.70 for the discharge.
Either I have Depleted Uranium for battery cells, or more likely the system is inputting some PV energy but not showing it in the logs is one option.
The sensors are just that bad, that they don't add numbers up correctly, which is where you, and I are seeing the difference.
