user to trigger an external event when a predetermined amount of
time has expired.PWM - Pulse Width Modulation can generate signals of varying
frequency and duty cycle.
The PIC16F887 microcontroller has two such modules - CCP1 and CCP2. Both of them are identical in normal mode, with the exception of the Enhanced PWM features available on CCP1 only[5].
3.Proposed Charge ControllerThe main parts of a solar home system are : PV cell, solar
charge controller, storage battery ,and load (as shown in figure 2).
