that’s a nice piece of equipment, but a high cost for only 130 watts. there are cheaper alternatives, but the concept is the same. it may be possible to step down in octaves of volts. converting from 70-90 volts down to 12 would pull much less current from the capacitor bank than when the bank gets down to a lower range like 15-30. my thinking is, converting from such a wide range would have inherent inefficiencies.

EDIT: actually, thinking about it, how complex would the charge controller be to efficiently charge the capacitor bank from solar panels? you wouldn’t want 90 volts going into a dead bank, as you’d have much current loss without converting it down.
