I am using Adafruit's solar battery charger and it does charge a Li-Ion battery from a solar panel as it should. It also powers an LED driver from the battery at night. The problem is that the LED driver is always powered and I want the LED to be powered only when it is dark.
From what I read so far, it seemed that a P channel MOSFET would serve my purpose - when the gate is high (solar panel in daylight), the P channel MOSFET disconnects the load, when the gate is low (solar panel covered/at night), it connects the load.
This is not working, see attached schematic and circuit, so how should I change my set-up?
Many thanks in advance!
