Random Charging of the battery at 00:30

Hi There

for some reason my battery started to charge this morning at 00:30 from the Grid. It hasn't happened before and to my knowledge nothing has changed on the settings.

Would anyone be able to shine light on this so it doesn't happen again?

Thank you so much in advance

Chris

I'm new to all of this, but is it possible the battery was flat, and was trying to maintain it's minimum SOC of 5%?
