"FULL" means when the hydrometer indicates "full" not when some Looney Tunes meter gizmo dartboards a guess.
Exactly. Part of the reason whey I chose the BS SC30 controller. It doesn't guess when the batteries are full. It let's me tell it exactly what to do and for how long.
I think senor Mex meant bean-counting feature of battery monitors - determining SOC by counting AH in-out.
He is right, this is merely an estimate. Can be useful to estimate SOC in less than Full stages. This is why it isn't very useful to me, as my solar brings batts to Full in the evening 9 days out of 10, and CC itself keeps a log. No hydrometer, AGM won't take it. If log says that it exited Abs after 5 minutes - because the current dropped to 2.5A for 300AH bank - and then spend 5 hours in Float, it's as close to Full as it can be said about this black box. Or - if current is zero when fridge isn't cycling.
Telling CC what to do is fine as long as you know what to do. 30-minutes time for Abs in storage, taken off the top of your (and their engineer's) head is a guestimate. I would observe it for a few days, making notes how soon the current drops to, say, 2-2.5A for 225 AH bank. If it's 3 or 5 minutes, then set it so. A bit of pain to do this manually, but with this CC seems like you have no choice.
