I have 200watts of solar. On the sunniest day in Tucson it stays in bulk mode all day, only a few times has it ever floated. My batteries voltage is slowly falling. I am in an RV and on the road. I have been running the generator to get the voltage to 13.6. I have two new AGM group 31 batteries. My system is wired differently. I have no loads connected to the charge controller. I believe the loads are directly wired to batteries. I did not wire the system it was done by a previous owner. I have older Trace 2000 watt inverter. Everything works great other than the charge controller. It barely allows 1 amp to pass trough the charger and seldom uses 20 watts of solar, the norm is single digits. I am using the battery life algorithm. If I try to manually start an equalization it doesn't complete itself.
