Part two of my series on parasitic loads in offgrid solar systems and the dramatic effect they can have on the amount of batteries you need and the overall efficiency of your off grid solar system. In this video I talk about something I’ve done that has dramatically reduced these parasitic loads – the use of DC/DC (or ‘buck’) converters – throw away your wall warts and enjoy a much more efficient system. Here’s some references:-
