Zener Diode to regulate solar voltage Answered
I'm new to electronics, and I'm having trouble with varying voltage.
I'm running a 6V solar panel through a charge controller, and out to a lithium battery (3.7V) and a load (3.7V), in this case a GPS data logger. My issue is the varying voltage to the GPS.
The GPS works perfectly off the battery (constantly diminishing voltage), but when the solar panel kicks in the voltage increases, the GPS thinks it is being charged, and switches off. The GPS will work on any voltage above 2.75V
I was wondering if I put a 3V zener diode in series between the charge controller and the GPS, would this keep the voltage at a constant 3V even if the solar panel is producing the 5V needed to charge the lithium battery?
I hope this makes sense
