12v from 24v Battery Bank ?
With two 12vs in series and the 24v charger on the other two posts, can you draw 12v at the same time as they are being charged at 24v, from the pos and neg of just one of the batts? If so, will th...

If 24v panels remain so much cheaper than 12v panels and MPPT controllers remain so much more expensive than PWMs, then the solar choice would be 24v on 24v battery using PWM..
My "goal" is as stated. Redundancy when off grid. Expanding on that for other scenarios is interesting too IMO, but it is not new of course.
I have been thinking how this could go ever since smk reminded me on here you can run 24v panels with PWM, no buck converter, IF the batteries are also 24v.
