I have a quick question,
If I want to measure the voltage at an input of a PV panel (24 - 48V, 220W), and give that to a microcontroller for ADC purpose (0 - 3.3V ADC range), will it be enough to just use a voltage divider (by a factor of 16 = 48/3)? Is this safe and/or efficient?
Or do I need to use some fancy circuitry using Op amps as an ADC interface (for better resolution)?
