This video is in responce to many questions I get about how and why my system is setup this way. Photovoltaics is very overlooked for heating options. In this video I will show all my water heating options and try to show you how it all works. The number one question I get is why I use "old school charge controllers". They are great for a well ballanced hybrid grid tied system. The cool thing about them is they can be used as LOAD CONTROLLERS witch enables you to heat water instead of letting excess power go to waste in an OFF GRID situation.
