DAY 311 OFF THE GRID - *"Stereo" current boost circuit*

Подробнее о видео

Here's my latest circuit design to allow extra panels to be connected to a small PWM charge controller. This one is specifically designed for the BP 'GCR' series of controllers, as these use a shunt method to regulate the power from the panels in PWM mode. It could be used on any shunt switching controller though and (with a small modification) on series type switching ones too.

This particular build is "stereo", inasmuch as there are two separate boost circuits built into the one unit as it is intended for by uber-balanced 24 circuit in Shed 'B'.

Unlike some of my other designs this one does not attempt to convert a +ve common controller into a -ve common one. I did not need that functionality in this circumstance. And doing away with that makes the design much simpler and not requiring any kind of "boost voltage".
