CA T, thanks. If Vbatt was say 12.2, at what panel voltage would charging begin?

The short answer is Vp=12.7, Vbat=12.1 and Abat=1.2

So, your 24v panel only had to be at 12.7v to initiate charging? Or am I misinterpreting that?

The Abat represents output from the controller and actually started at less that the 12.7V panel voltage. The amps would be supplying house loads since the battery voltage is to low for any real charging plus amps are also low. I kept the battery voltage low with house loads since I wanted to see how the panels and controller would work. I'm not a big fan of discharging my house batteries say overnight just to run a test and hence use house loads.

I'll see about posting some graphs.
