Just noticed battery not taking charge at all
What can be done ?

Some more info will help people give sensible advice but if all else fails call Givenergy and they will be able to help.

What equipment do you have?
What is the percentage of the battery?
Is the sun shining?
What are your solar panels producing?
What is the house consuming?

You could try restarting the Inverter from the dashboard.
