Harness the power of the sun and optimize your solar energy system with a PWM Solar Charge Controller

This PWM Solar Charge Controller regulates the electricity flowing from your solar panels to your batteries. So it can ensure safe and efficient charging.

Choosing the Right Charge Controller: PWM vs. MPPT

In solar power systems, there are two ways to control how batteries are charged from solar panels: PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking).

PWM Solar Charge Controllers:

  • Simpler and lower cost
  • Efficient at constant power levels
  • May not be as efficient under variable lighting conditions
  • Operates by rapidly switching the connection between the solar panel and battery. Well then, this on-off switching wastes some energy.

MPPT Solar Charge Controllers:

  • More advanced and efficient
  • Can extract more power from your solar panels, especially in variable or shaded conditions
  • Generally higher cost
  • Uses a sophisticated algorithm to continuously optimize the output from the solar panels to match the battery’s needs. And then, this results in increased energy harvest.

  • Real-Time Monitoring and Control (LCD Display and Button Control)
  • Extended Battery Life with Automatic Temperature Compensation
  • Automatic System Voltage Detection (12V, 24V, 36V, or 48V): Simplifies setup by automatically recognizing your system’s voltage.
  • Customizable Charging Parameters for Multiple Battery Types: Supports lead-acid and lithium batteries
  • Comprehensive Protections: Over-current, short-circuit, and temperature protection features safeguard your system from potential damage.
