MP2 going into idle mode

I have a MP2 with a Epoch Essential 300 amp hour battery, it appears the MP is going into idle mode after charging the battery to 100%, it doesn’t do it immediately it takes about 10-15 minute’s. I am tracking down to these possible issues:
MP is shutting down to prevent overcharging?
MP has wrong setting for battery discharge?
My temp sensor attached to the battery and Cerbo is not giving accurate reading?

What should I do?
Thanks ou

What do you mean with “idle mode” ?

The charger is finished with bulk and absorption, it will have to wait for the battery to fall down to float level before it has any real challenge to meet.
