Not really a problem if you look a little closer.
From my system today.
About 11:30 the battery reaches the batteries target bulk voltage of 14v.
Mppt goes to absorption, current reduces to maintain 14v.
About 11:50 after the programmed absorption time has elapsed, mppt changes over to float. Target float voltage is 13.35v.
It take about 30 minutes (with a inverter/fridge as load) for the battery voltage to finally drop down to the float voltage.
During that 30 minutes, the battery is powering both the inverter/fridge/other small loads.
The loss of solar input during this 30 minutes drains my battery by 1% Soc.
No harm to my battery Soc.
Once the mppt has switched to float it maintains that battery voltage/Soc
until there is no longer enough sun available.
I do see that the period between absorp and float cuts solar production to zero.
Though, once the mppt has switched to float, it maintains the battery voltage and Soc.
