“I have a 12v 271 ah pack that I built for my truck camper and it's usually fully charged by the time lunch is finished, when there is full sun. It takes all day on a cloudy day. This is with 600 watts of solar panels.“
Though my system is a bit smaller than your’s (@200a/h LFP, 440w solar), the charge recovery advantage is substantial, and peak harvest times are considerably exploited - this attribute is pretty much a ‘settled science’ (per the principle of Occam’s razor...) and likely why NASA chose a Lithium variant for Mars Opportunity Rover’s energy reservoir...JMO
