WebOk, it's a moot point - attempting to power a MPPT 75/15 controller or any similarly designed buck regulator indeed "won't work", but only for the simple reason that the input voltage needs to be somewhat higher than the output. The manual for the 75/15 notes at least 5V higher to start, and 1V higher to keep running. i.e. the nominal 13.8V car battery has no … Webinput voltage to a 43.5V output voltage, whereas the power optimizer of module #9 is acting as a down converter, converting the 28V input voltage to an 8.7V output voltage. The various system currents and voltages in this case are illustrated in Figure 2. Figure 2: Operation with Partial Shading
