Multiplus 12/1600/70

Hi there I have a multiplus compact 12/1600/70 and 4 x100 amp hr lithium battery set as 12 volt bank. My problem is that the charger is in float mode and my coulometer is saying 68% charge and 260 amp hr remaining . My solar controller is trying to to put boost charge in. Why won’t the multiplus recognise the batteries are low and put charge in?

What are the charger settings in the MultiPlus? Compare those settings with your solar controller.

If you turn the multi off wait 3 min then turn it back on it will go back into bulk mode

then

Please advise what the voltage is when it switchs to absorption and then the voltage when its in float .


Also what are you using to read your SOC reading
