How bad, if any, for Lifepo4 batt float charging 5 - 6 hours/ day, every day ?

[new off grid]

Hello every one,
My solar system is a bit overkill when Spring/summer coming
the 3 batt of 20kwh total @ 48v will be full at around 1 Pm
they're running in floating mode, at nearly 100% SOC, during the rest of the day, until 6 - 7 Pm
it's 5 -6 hours long sitting at full every day
nothing I can do about it, everything setting up automatically
how bad, if any, will affect the batt cycle life ?
Bulk/Absorb/Float voltage set to very low, at : 3.43 / 3.41 / 3.38 respectively
Thanks all ppl
good day,

The converter in my trailer sits at 3.40 per cell (12V system). I tweaked balancing to start at 3.30. It's passive JBD so pretty slow balance. I call it pretty darn full. If I bump the voltage up, I'll see a runner so I keep it at 3.40.

so you suggesting lower the charging voltage a bit more ?
