Had to Lower My Solar Float Voltage-Update
Updated 9 July Just a note for folks in a similar situation. My usual procedure in a normal summer here with my set-up with the Eco-Worthy controller (adjustable Absorb and adjustable Float ) is...

AFAIK the various "stage" voltages in a charging profile are all rated at 77F/25C.
The trouble as usual is trying to figure out what the electrolyte temp in a battery is when it is being charged, at what SOC, at what ambient temp outside the battery? Too complicated!
So, lucky me, my controller has two adjustable voltages and I don't have to do any work after all, by pure chance. (saving me the extra $500 cost of having a controller like smk's :) ) BUT what if I were using my single settable voltage Solar30 in this same situation?
I want the batts to reach a Vabs in the 14s but now I don't want them to to stay at that voltage the rest of the day till dark. What to do?
A. change the voltage manually mid-day to 13.2 and then back to 14.x before going to bed (solar starts before Wakey- Wakey) or
B. let the batts reach Vabs and full SG and then just disconnect the solar, or
C. what?
I suppose all this is because once again, I am finding I have too much solar (255w in a tilted twirler--daily usage under 70AH) for the summer months. (Just right for Spring and Fall though) Who says you can't have too much solar? :)
