Hey I am after a design for my solar setup. I want to have the battery powered by either solar or wind when its available and if not then mains power. of course I want to go with a overcharge protection and minimum voltage protection.
I was thinking the easiest way was a microcontroller but thought I would ask before going head deep into it to see if anyone has any other ideas of how to approach this on the cheap

my first thoughts are diodes, it could charge from either source without the risk of barckcharging the other, overvoltage Im not sure, but undervoltage just throw a zener in there or a few in line to get the voltage drop of the lowest you safely can
