My Smart Solar MPPT 100/50 charges my 4 x 100ah lithium batteries by midday at the moment and solar charging is terminated when the full charge threshold is met.
This is my first season with uprated solar panels (now using 2 x 60 volt 330watt Hitachi panels) and I have never seen full charge characteristics before and I am not sure what the correct behaviour should be, but I am noticing that after several hours, my batteries are discharging and the solar controller doesn't cut back in and resume charging.
If I go into the mppt settings and disable charging and then re-enable it again, I see normal charging resume again.
What is considered normal behaviour once the batteries are starting to become discharged, for example down to 95%?
