Home >> bosun outdoor ip66 12v dc mppt charger controller 20w 30w 50w solar led road lamp
this is a simple solar boost converter and voltage limiter circuit that charges a 12v battery from a 6v solar panel. it also demonstrates mppt (maximum power point tracking) capability. when we think of mppt, we generally think of microcontrollers and complex power computing algorithms, but such computing power is not actually required.
traditional pulse width modulated (pwm) solar charge controllers have been around for several years and force your solar panels to operate at the same voltage as your battery bank during charging. they tend to be less expensive than mppt (maximum power point tracking) charge controllers, but they're also less efficient than the mppt type.
