PWM Charge Controllers
Renogy’s PWM, or Pulse Width Modulation, controllers are perfect for just about any small
scale application! Need to run LED lights in your RV? Want to power a 12V refrigerator on your boat?
PWM controllers act as a constant voltage regulator. They emit a pulsing signal to the
battery in order to determine and maintain a healthy charge level -
making PWM controllers ideal for smaller systems.
