Unexpected exporting to grid

[gxaxrxy2025]

Hi all
Today the minimum battery cell temperature is 15.6 degrees C so it should be charging.
Battery SoC is 98%
Solar panels are producing 4.56kW
but system is exporting 4.04kW to the Grid?
Why am I exporting when the SoC is less than 100%?

Once the batteries have reached 100%, the BMS holds the charge and doesn’t allow it to charge again until the cell voltages have dropped - that’s usually around 97% when it allows them to charge again.
It’s a battery ageing anti-cycling protection mechanism so that the batteries don’t sit charging all day long.

Okay, that sort of makes sense then.
I guess I need to read a Dummies guide to Solar Power!

Thanks for the reply
