Stupid battery and solar questions
I figure I am going to have a lot of them, so I better put all in one thread :B. My situation: - I mainly want solar for running residential freezer and fridge, maybe also for charging my shave ...

There is no bulk or absorb phase for surplus acid AGM.
I guess because they are meant not for fast charging/discharging, but rather for floating forever. They are backup batteries.
What happens when a typical PWM controller will be forcing 60-90 minutes Absorb stage on it, every single day? Most PWM won't let you disable Absorb.
Nothing happens. You set the voltage for 14.4V, the battery charges up, and not much else happens if there's 14.4V sitting on it and the battery is fully charged... the current taken drops off to 0. I see it every time on my RC watt meter when I top charge upon return home from a trip, with my 30 amp MegaWatt PSU. It might take about 2.5 to 3 hours to top off the last 3-4 amps of recharging.
Some of the panel's output during the day is used to run the parasitic 24 hours a day usage that the smoke alarm, refrigerator, water pumps and what ever else use 24/7 when camping. If there is nothing drawing current, the panel doesn't produce the current.
