I simply set the battery charge parameters and inverter LBCO as I would with Lead Acid, but using the numbers for LiFePO4. I've said before (in other threads) that I think the closed loop stuff is over-sold. I see a small benefit to lower the charging current near the end to allow balancing, but I've not really seen any problem with not having that. In the end, whether it is LiFePO4 or L-A you have numbers (bulk voltage, absorption voltage, float voltage, max absorption time, and tail current. You can just set these to work great for LiFePO4, or you can set them to work great for L-A.
Having said that, my 6 year old Schneider CSW4024 does have some quirks that make working with LiFePO4 a bit harder. For one, there seems to be a bug that won't let me set the charger to a bulk voltage of lower than 28.8V, which is significantly higher than the 28.0V I would prefer. Second, at least my version of the firmware doesn't let me set the LBCO higher than 24V (3V per cell). I would have preferred 24.8V (3.1V per cell), but I guess 24V will do.
