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 ...

Hi,
High rate means they are perfect for folks such as myself who want to use an inverter. High rate, in some ways, is a meaningless term. Battery cells are rated to do 25 amps. Doing more than that causes voltage drop. That means the effective capacity gets lower pretty quickly.
I currently have 4 12 volt jars so I can do 100 amps without much voltage drop. But the microwave draws 170. It is not uncommon for me to see a load of 276 amps.
My bank is currently 556 amp-hours on 4 12 volt batteries in two banks wired in a balanced manner.
Since they are AGM batteries there is no need to equalize (from solar) and reconditioning will, I hope, be rare.
This telecom form of AGM is a "surplus acid" and ought to be treated much as if it were a flooded batter, i.e. do not go below 50%. They also need to be returned to 100% state of charge after each cycle as often as is humanly possible.
