Sun Solar Charge Controller Pwm 50a 12v/24vS-pwm-50-sun

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.
