What nonsense. The controller turns the panels OFF at the appropriate
time. It doesn't manufacture power from thin air. I wouldn't buy his
product because he lied to me.

How do the Maximum Power Point controllers work?

OK, nobody's answering me - I'll try it myself...

IIUC, the "power Point' controllers are basically DC-DC converters,
converting the 19 volts or so that the panels produce to 12.6 (or
something), thus drawing from the panels at their output voltage instead
of the battery's voltage. Presuming minimal change in current delivery,
this would represent an increase in delivered power.

OK, where am I wrong here?
