 +Renogy Li profiles are charge-and-stop: 
 + 
 +  - charge to the selected Boost setpoint 
 +  - stop charging 
 +  - drift down to the reBoost setpoint, typically 13.2v,if loads are present 
 +  - start the charging cycle again 
 + 
 +If you want to //hold// a 13.2v floor instead of cycling repeatedly you might charge use a Pb profile to charge to 14.1v((the lowest available)) and "float" at 13.2v.  This would let the bank relax to somewhere between ~60-70%,((it's notoriously hard to predict, so play with it - secessus)) although with light loads you might not fall to 13.2v until sundown.  
 + 
 +A 13.8V float is unacceptably high((IMO - secessus));  it would pin the bank at 100% all day.  13.5v, the last option, may be acceptable if you are running heavier loads.  13.5v will put constant (albeit relatively gentle) charging pressure on the bank.  Experiment with it;  if it pins SoC at 100% all day then 13.2v might be healthier for the battery.
