Warm greetings
I have not much experience nor knowledge about electronics so that's why I need and ask for some guidance and help from those who do!
There are three common manual- or fixed mpp modules available for purchase. sd30crma, CN3767, BQ24650. Problem with those is they are quite expensive.
I was wondering if there is a simple way to modify the HW-613, an highly efficient (96%, 22w stable output with heatsink!) and super affordable (10 times+ cheaper than the mpp modules listed above!) buck converter,..
.. so that it holds the input panel voltage at mpp 18v for a 22v panel (add somewhere a trim resistors? Where?)? I am looking for a easy hardware solution.
Does anyone happen to know how to do that and could you kindly explain me how to do it exactly? Which parts (value of resistors... ) do I need to get for this little hack?
Much much appreciate your help!
