Hi Guys,
I've been racking my brain for ages and this is the best i can figure for dividing (up to a 65V) solar pannel voltage to a useable uController ADC voltage.
Only problem is, there must be a better/cheaper way of doing it as this requires a 65V opamp and I cant find any. In fact this one is only 35V.
This needs to work for a uC running off a 12V battery on the 'battery terminal' of either a common positive or common negative Solar charge controller.
GND in this schematic is battery 12V GND.
Any help would be appreciated.
