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 recharging needs.

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.

·Mutiple Electric Protection.

·High efficiency series charging mode extends battery life.

·Dual mosfet reverse current protection, low heat production.

·Comes with a display that can clearly indicate the status and data.

·Prevents batteries from over-charging and over-discharging.
