With FLAs doing successive incomplete recharges in a row leads to Progressive Capacity Loss. We talked about this on here about ten years ago. You must do a "recovery" to Full every so often or your capacity gets so low you can't get through the next night. Depends on the whole scenario how many days you can do it.
Solar solved that by doing shallow instead of deep cycles and by getting close to or even to Full often when the sun is out. You still have to get to Full every so often and do an overcharge per battery guidelines.
Here is a plot showing PCL with five successive 50-90s I did about ten years ago.
