The BQ24650 device is a highly integrated switch-mode battery charge controller. It provides input voltage regulation, which reduces charge current when input voltage falls below a programmed
If available solar input power is low, and the low input power causes the charge current to fall below 0.38 X current set-point at any time the battery voltage is above 13.55V, then the charger aborts the charge cycle, bypassing bulk and absorbtion stages and goes straight to the float stage. I believe this is the behaviour that the OP was seeing.

This charger is a breeze to use for solar projects: pick up any of our many 3.7V/4.2V LiIon batteries, and a 6V solar panel.
Plug the battery into the BATT port using a 2-pin JST PH cable and the solar panel into the DC jack using a 2.1mm adapter cable Put the solar panel outside (and keep the battery out of the sun, it needs to be kept cool!) to start charging.
That keeps your battery from constantly charging/discharging which will reduce the battery life. The max draw from USB / DC / Solar is still 1A, if you need more current it will come from the battery and the chip can provide up to 3A current spikes from the battery to the load output!
