More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

I suspect you might be onto something, but also suspect you are confusing yourself, which is why am seeking clarification.
eg, above you say it is the voltage not the current but then say it needs current to make it happen. ?
Also we have the switch from constant current to constant voltage for the Stage 2 absorption phase. At this constant voltage of 14.7 (say) the current tapers specifically to prevent the battery from overheating and gassing "too much" --we want some gassing.
The whole point there is to reduce the current as SOC rises while voltage remains at 14.7. So why worry about reducing the current if it is the voltage that causes the gassing? I don't get it.
I agree that holding the battery at high voltage after it has been charged -no current- will keep it gassing and it will lose water. but here Mr Wizard's batteries are not charged yet, and the controller will prevent "too much" gassing, while allowing the desired "some" gassing.
So is this just all about how much gassing is "too much" for "too long?" The time factor (too long) is taken care of every day around sunset isn't it? Doesn't that also take care of "too much?" whether it is voltage or current?
