24-48volt Charge controller Load diversion

In the last few months i received a lot of emails asking me about the 24volt and 48volt variant of the charge controller.

 So i set myself to design a new controller with some common features such as  simplicity and common parts.Keeping in mind the original design i endedup with a controller that can work with 24volt systems and 48 volt systems just by chaging the reference resistors and  wiring in the pre regulator in circuit. 

the result is the picture shown here. i have a prototype and shall have the boards shortly . the unit will be supplied as a kit and pre assembled and aligned unit.
