Pulse Width Modulation (PWM) Solar Regulator is the most effective means to
achieve constant voltage battery charging by switching
the solar system controller's power devices. When in PWM regulation, the
current from the solar array tapers according to the battery's condition and
PWM solar chargers use technology similar to other modern high quality battery
chargers. When a battery voltage reaches the regulation set point, the PWM
algorithm slowly reduces the charging current to avoid heating and gassing of the
battery, yet the charging continues to return the maximum amount of energy to
the battery in the shortest time.
