The most important job of all solar charge controllers is to properly charge the batteries and to give them as long a life as possible. There are two types of charge controllers: Pulse width ...

Working This is a PWM (pulse width modulation) based charge controller. PWM based charge controllers are very efficient when solar panel are of 20V open voltage and battery max voltage is 13-14 volts.

Do not use mbed Ticker class, as it disturbs the timer settings and might cause the charge controller to crash. In addition to that, it contains a lot of overhead and is not very efficient. Timers ...
