Eventually will reduce battery life.
Try setting the bulk time out higher, about 2-3 hours, and restore the 13.6v float.
Also, why do you need 100% soc? 95% to 97% is fine and will give a longer lifetime. Works for me.
My Victron Smart Solar has a Tail Current setting that will early exit bulk (14.2v, 1 hour) when the current drops below my 10A setting. Also it measures voltage at the battery via the Victron Smart Shunt, which corrects for cable voltage drop.
Your SCC measures the voltage at it's terminals, not at the battery. Are your SCC to Battery cables lenght short? The largest gauge the SCC battery terminal accepts? No circuit breaker in the path.? Fuses have less loss.
The RV WFCO converter supplies 13.6v and it takes many hours to hit 95% charge. It takes a long time due to the cable resistance. After 40 hours it drops to 13.2v storage.
