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.


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

    No, we do not recommend that. The PWM charge controller is not designed to communicate to each other. Hence, batteries will only be getting charge from one controller.

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

    Unfortunately, PWM charge controllers does not have User/programmable setting.

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

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

  • 4. Can I use this controller with DC alternator or Wind turbine?

    No, the charge controller is only compatible to accept input from solar panels.
