I don't even understand what my question is! Anyway, still in a muddle.
Two 100AH 12v batteries. As a 24v get 100AH As a 12v get 200AH
Acceptance rate for charging the 200AH/12v is say 40a, what is it for the 100AH/24v?
So do you need the same size controller in amps whether 12 or 24 battery, or what?
How long does it take to charge each bank? Same time? half the time, twice the time?
Now you have a 40amp controller at 12v. Is it still a "40amp controller" at 24v? So its 40amp limit is the same? What about its input voltage limit? Same?
Last year we got into another muddle over the limits for the MS 15L, ISTR, which turned on it having a 200w or a 400w limit depending on system voltage?
So do these controllers have different limits for different situations or not?
I am unclear on sensing wire importance in all of this but mentioned since that is the real topic :) Sorry, OP! :(
