Battery not charging, even when surplus is exporting

[albie999]

Just noticed this tonight, as the sun is going down ... not sure why, but my battery is not charging (even though at 98%) and there is enough Solar to charge, as it is actually exporting some of it. It is set in "Self Use" Mode

That is normal behaviour, when the battery is full the BMS reduces the allowable charge current to zero, depending on state of charge, temperature, age and cell balance the BMS will then wait before allowing the batteries to start charge again (which reduces unnecessary cycling) - typically it drops to around 97% and then will start to charge again.

Thanks for the explanation Dave ... Still new to my system, so still trying to understand it's behaviour
