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, determining and maintaining a healthy battery charge level.


  • Can I wire two charge controllers in parallel to one battery bank?

    No, PWM charge controllers are not designed to communicate with each other.

  • Can I change/adjust the charging parameters on PWM charge controllers?

    Unfortunately, PWM charge controllers do not have a user-programmable setting.

  • Can I cover or mount the charge controller in an enclosed box?

    The charge controller should be mounted in a well-ventilated area with 9-inch clearance around it as it will convert the excess voltage into heat and dissipate into the air.

  • Can I use this controller with a DC alternator or a wind turbine?

    No. The charge controller is only capable of accepting input from solar panels.
